Understanding Storm Risks to Greenhouses in the UK
Greenhouses in the UK face a mix of weather threats that can cause rapid damage and long-term wear. Rising storm frequency recorded by the Met Office has made awareness of UK weather risks greenhouse essential for every gardener and grower. A clear grasp of common hazards helps prioritise practical, cost-effective protections.
Common UK weather extremes that threaten greenhouses
Autumn and winter bring high winds and gales that test frames and fixings. Storm Eunice in 2022 showed how a single event can shatter glass and tear polyfilm across large areas. Coastal and exposed upland sites see higher gust speeds, while some summer storms deliver intense, localised hail and driving rain.
Heavy snow creates load hazards for flat or low-pitched roofs. Sudden temperature swings lead to rapid expansion and contraction, stressing seals and glazing. Each of these elements feeds into the overall picture of hail and snow greenhouse risks and the separate but related danger of wind damage greenhouse.
Typical weak points in greenhouse construction
Many failures trace back to anchors that are too shallow or absent. Lightweight glazing such as single-sheet polyfilm lifts in strong gusts. Poorly secured doors and vents act as sails, increasing uplift forces. Corroded fixings and weak joints reduce the structure’s redundancy, leaving base sections and narrow frames vulnerable.
Glazing failures often start small: a cracked pane, a slightly loosened polycarbonate panel or a torn seal. These local failures let wind and water into the cavity, raising internal pressure and triggering cascading losses. Recognising these failure modes helps focus repairs and upgrades where they matter most.
Assessing site-specific exposure and wind patterns
Start with local wind maps and Met Office records to understand regional patterns. Ordnance Survey contours indicate potential channelling across slopes. Observe prevailing wind directions from nearby buildings and hedges. Coastal plots face more frequent gale-force winds than sheltered suburban gardens.
Simple tests are useful. Flag a lightweight ribbon for a week to record gust directions. Walk the perimeter during a windy day to feel how gusts accelerate around corners. Combine these observations with local weather records to form a practical risk picture and carry out a basic vulnerability audit.
| Threat | Typical effect | Common weak points | Immediate sign |
|---|---|---|---|
| High winds and gales | Uplift, frame distortion, blown glazing | Shallow anchors, unsecured vents, lightweight glazing | Loose fixings, rattling panels |
| Hailstorms | Punctured glazing, damaged plants, torn films | Single-sheet polyfilm, unprotected vents | Cracked panes, holes in film |
| Heavy snow | Roof collapse, bowed frames | Low pitch roofs, narrow base sections | Bowed roofline, sagging panels |
| Driving rain | Water ingress, rot, corrosion | Poor seals, corroded joinery | Water trails, rust stains |
| Temperature swings | Seal failure, glazing stress | Tight frames, brittle seals | Split seals, fogging between panes |
Making a Greenhouse Storm-Proof
Start with a clear aim. Decide whether you want full structural resilience to withstand severe gales, operational resilience to protect plants and equipment during a storm, or recoverability to keep downtime and repair costs low. Bear in mind that making a greenhouse storm-proof sits on a spectrum. Total immunity is unrealistic, yet careful choices cut risk substantially.
Defining objectives: What does storm-proof mean for your greenhouse?
Set measurable goals. For structural resilience, aim for stronger framing, improved foundations and higher-spec glazing. For operational resilience, focus on secure benches, tied-down pots and reliable ventilation closures. For recoverability, prioritise designs that allow fast replacement of panels and clear routes for repair crews.
Prioritising structural integrity versus temporary protections
Decide based on use and value. A commercial grower with high-value stock should favour permanent upgrades. A hobby gardener may choose temporary protections to save cash. Permanent measures include galvanised frames, concrete bases and laminated safety glass. Temporary options range from removable internal bracing and storm straps to battening down vents and tarpaulin covers.
Long-term resilience planning and budget considerations
Plan across a 5–10 year horizon. Inspect each season, budget for incremental upgrades and factor in inflation. A basic budget and priorities list helps when grants or insurance discounts appear. Create a greenhouse resilience plan that tracks inspections, upgrade dates and replacement costs.
Below is a simple prioritised action plan by budget bracket.
| Budget | Key measures | Expected lifespan |
|---|---|---|
| Low | Ground anchors, inexpensive external windbreaks, internal ties for benches and pots | 3–7 years |
| Medium | Multiwall polycarbonate glazing, reinforced door and vent closures, concrete or screw-pile anchors | 7–15 years |
| High | Galvanised steel frame, full concrete base, laminated safety glass, bespoke venting and automated closures | 15+ years |
Use storm-proofing priorities to guide spending and timing. Start with fixes that prevent collapse, then protect contents, then invest in speed of recovery. Regular maintenance reduces long-term costs and may lower insurance premiums. A clear greenhouse resilience plan turns occasional upgrades into a coherent strategy that keeps plants safe and buildings standing.
Choosing Robust Materials and Design Features
Picking the right glazing and frame makes a real difference when you want a greenhouse that survives gales. This brief guide compares common options and highlights design choices that cut uplift and racking in exposed UK sites.

Start with glazing. A polycarbonate vs glass greenhouse decision hinges on impact resistance, light and longevity. Multiwall polycarbonate panels from brands such as Palram or Brett Martin give high impact resistance and good thermal insulation. They are lightweight and resist shattering in hail.
Toughened or laminated safety glass offers superior light transmission and a long service life. Glass needs stronger supports and often a concrete base because it is heavier and more fragile under impact. Lamination reduces dangerous shards if breakage happens.
Horticultural film remains a low-cost option for polytunnel-style covers. It is simple to replace and ideal for seasonal use. The film tears more easily in high winds and hail, so it suits temporary or low-cost projects rather than permanent, storm-proof structures.
Choose frame materials to match site exposure. Aluminium frames are corrosion resistant and light, making installation easier. For high-wind sites use thicker extrusions and secure anchoring to avoid flexing.
Galvanised steel gives excellent strength and durability for larger or commercial greenhouses. Its greater mass resists deformation in storms and pairs well with heavier glazing such as glass.
Treated timber brings a classic look and some thermal mass. It needs regular maintenance and careful treatment against rot and insect attack. Use generous section sizes on exposed sites to achieve comparable resilience to metal frames.
Quality components reduce failure risk. Fit galvanised or stainless-steel fixings, EPDM rubber gaskets for weather seals, and polycarbonate clips rated for wind load. These choices keep joints watertight and reduce movement under load.
Design features matter for uplift control. Steeper roof pitches—typically 15–30 degrees depending on the model—help shed wind and snow. Low-profile layouts and compact footprints cut the sail effect on open sites.
Vents should equalise internal pressure to prevent uplift. Roof vents work better than large side vents in strong winds. Fit automatic closers with lock-down options so vents cannot be forced open by gusts.
Reinforcement methods such as cross-bracing, internal T-braces, steel struts and shear panels stop racking. Specify load ratings for bracing where possible. These measures, combined with strong greenhouse frames, provide a coherent defence against storm forces.
| Component | Advantages | Limitations | Best use |
|---|---|---|---|
| Multiwall polycarbonate | High impact resistance, good insulation, lightweight, UV-stabilised options | Lower light transmission than glass, can scratch over time | Domestic and exposed sites needing hail resistance |
| Toughened/laminated glass | Superior light, long life, aesthetic finish | Heavier, needs stronger frame and base, more vulnerable to impact | Permanent installations where light quality is priority |
| Horticultural film | Low cost, easy replacement, flexible | Prone to tearing in wind and hail, shorter lifespan | Seasonal tunnels and temporary covers |
| Aluminium frame | Corrosion resistant, lightweight, low maintenance | Can flex in high winds unless heavier extrusions used | Moderate exposure sites with careful anchoring |
| Galvanised steel frame | High strength, durable, resists deformation | Heavier, may need concrete base and skilled installation | Large, commercial or high-wind installations |
| Treated timber frame | Aesthetic, good thermal feel, easy to work with | Requires maintenance, risk of rot and insect attack | Garden settings where appearance matters and upkeep is planned |
| Fixings and seals | Galvanised/stainless fixings and EPDM gaskets extend life | Higher initial cost for quality components | All installations for long-term reliability |
| Design & reinforcement | Steeper roofs, roof vents, cross-bracing reduce uplift | May increase build complexity and cost | Exposed sites where storm resilience is required |
Foundations and Anchoring Strategies
Choosing the right base and anchoring system is central to keeping a greenhouse upright in British gales. Sit it where the ground drains well and natural shelter reduces wind exposure. Avoid ridge tops and narrow funnels where gusts concentrate. Align the long axis parallel to prevailing winds to cut down cross-section and uplift risk.

Siting the greenhouse for natural shelter and drainage
Pick level ground with good fall-away so water runs clear of foundations. Place the structure near a hedge or fence at the right distance to break winds, not create turbulence. If soil stays wet, raise the base on gravel or a shallow compacted rubble layer to avoid standing water that undermines anchors.
Concrete bases, ground anchors and screw piles explained
Concrete bases give a rigid platform that suits large, permanent glass greenhouses. Reinforced edge beams and a DPM stop rising damp and provide solid points for through-bolts. For smaller frames, ground anchors or augers are cheaper and less invasive. Install multiple ground anchors greenhouse systems rated for uplift, and match depth to soil type; sandy soils need deeper embedment.
Screw piles greenhouse options work well where concrete is impractical or on slopes. These helical piles require minimal excavation and deliver deep, dependable anchorage. Many installers such as local piling contractors fit them quickly when access is limited.
Fixings and connections that prevent structural failure
Use galvanised or stainless steel fixings to resist corrosion in damp UK conditions. Avoid relying on self-tapping screws alone; use through-bolts or robust bracket systems to join the frame to the foundation. Follow manufacturer spacing, with anchors at corners and midpoints for small greenhouses.
Consider drainage measures at installation. French drains, soakaways and a gravel perimeter reduce waterlogging and protect anchor integrity. Regular checks of fixings and surrounding ground help spot loosening before a storm causes more damage.
| Foundation Type | Best for | Pros | Cons |
|---|---|---|---|
| Concrete base | Large, permanent glass greenhouses | Rigid platform, excellent uplift resistance, secure for through-bolts | Costly, labour-intensive, needs DPM to prevent rising damp |
| Ground anchors / augers | Small to medium frames | Affordable, less invasive, adjustable placement | Depends on soil type; sandy soils require deeper anchors |
| Screw piles (helical) | Sloping sites, poor access, where concrete is impractical | Deep anchorage, minimal excavation, installed by specialists | Higher specialist cost, requires correct installation torque |
| Fixings and fittings | All greenhouse types | Through-bolts and brackets give strong connections; galvanised/stainless resists corrosion | Higher initial cost than basic screws, needs correct sizing and spacing |
Windbreaks, Shelterbelts and Landscaping for Protection
A well-planned perimeter is one of the most cost-effective ways to reduce wind stress on a greenhouse. Good planting and landscape shaping cut wind speed gradually. Abrupt barriers create turbulence that can batter glazing and strain frames. Thoughtful placement and porosity control the flow of air and limit turbulence close to the structure.

Mixed native hedges with hawthorn, blackthorn and beech make reliable long-term shelter. Plant at least 10–20 metres windward to give the hedge room to mature without casting excessive shade. Trim regularly to maintain a dense lower profile that breaks wind near ground level.
Trees give year-round protection when you choose species and siting carefully. Evergreens such as Scots pine and holm oak provide consistent screening. Keep larger trees well back to avoid root competition and the risk of limb fall directly upwind of the greenhouse.
Hedges and trees take time to mature. Start a shelterbelt for greenhouse protection early as part of wider resilience planning. Short-term screening can cover the gap while plants establish.
Artificial windbreaks
Porous fencing with 50–60% porosity reduces turbulence better than solid panels. Use close-board fencing fitted with spaced slats or purpose-built windbreak netting to allow a controlled passage of air. Temporary screens made from burlap or polywoven fabric are useful for seasonal reinforcement during high-risk months.
For materials and supply, consider Garden centres and specialist suppliers such as Forest Garden and Rolawn for robust posts, slatted fencing and windbreak netting commonly used in UK gardens. Match the product to exposure and maintenance capacity.
Designing landscape features to manage wind and water flow
Berms, terraces and earth bunds can slow wind and channel gusts away from sensitive glazing. Shape them to guide flow and to reduce sudden pressure changes at the greenhouse perimeter.
Gravel trenches, swales and permeable paving capture surface runoff and prevent erosion near foundations and anchors. These measures reduce splashback and puddling that can undermine base walls.
Permeable hardscaping close to the greenhouse helps drainage while keeping maintenance simple. Combine planting, shaped groundforms and correctly sized drains to protect the structure from both wind and water in high-intensity storms.
Internal Measures to Safeguard Plants and Equipment
Preparing the interior of a greenhouse is as important as strengthening the frame. A secure greenhouse interior protects plants and kit from becoming hazards in a gale. Small steps taken before a storm make recovery quicker and reduce losses afterwards.

Securing benches, pots and heavy equipment
Bolt benches to the base or use metal brackets to fasten shelving to uprights. Use straps or ratchet ties on benches and shelving to stop them shifting. Keep heavy pots and containers on lower shelves to lower the centre of gravity.
Anchor large pots and machines to fixed points with ground anchors or steel cables. Store loose tools in lockable cabinets or a small shed to avoid projectiles. Trolleys and movable benches should be blocked or chained down when a gale is forecast.
Protecting delicate plants: covers, staging and temporary shelters
Use horticultural fleece and frost blankets to shield tender foliage from driving rain and cold. Fit padded trays beneath pots to reduce root disturbance if movement occurs. Movable trolleys on rails let you shift groups quickly to safer zones inside the structure.
Create emergency mini-shelters with rigid frames and small polycarbonate panels for prize specimens. These temporary shelters give extra protection while preserving light and airflow. Quarantine newly sheltered plants to limit spread of pests or disease carried in by storm winds.
Watering, ventilation and heating strategies to cope with storm aftermath
Check soil moisture before rewatering; heavy rain can leave pots waterlogged and roots vulnerable to rot. Use raised benches and well-draining compost mixes to speed drying. Wait until the rootzone has started to dry before resuming routine irrigation.
Clear vents and check automatic venters after a storm. Blocked vents raise humidity and invite fungal disease. Test heaters and electric thermostats once power returns; consider battery-backed thermostats or a small generator for critical periods.
Inspect plants for pests and fungal symptoms; storms can carry insects and spores into the greenhouse. Quarantine affected specimens and treat promptly to protect the wider collection. These greenhouse storm preparations help limit damage and speed recovery for both plants and equipment.
| Task | Action | Why it matters |
|---|---|---|
| Bench anchoring | Bolt or strap benches to the base using brackets or ratchet ties | Prevents benches from becoming airborne and damaging plants |
| Heavy pot management | Place on lower shelves; secure with anchors or cables | Lowers centre of gravity and reduces risk of toppling |
| Temporary shelters | Use rigid frames and polycarbonate to enclose valuable plants | Provides immediate protection without blocking light |
| Covering delicate foliage | Apply horticultural fleece or frost blankets | Shields from driving rain, hail and cold |
| Post-storm watering | Assess soil moisture; delay watering until rootzone dries | Prevents root rot after waterlogging |
| Vent and heater checks | Clear debris, test automatic venters and heaters | Maintains airflow and safe temperatures to reduce disease |
| Biosecurity checks | Inspect, quarantine and treat affected plants | Stops pests and pathogens spreading after storms |
Maintenance, Inspection and Pre-Storm Checklists
Regular care keeps a greenhouse resilient and reduces repair bills after wild weather. A short, structured routine helps spot faults early. Use a simple plan that combines a seasonal greenhouse inspection with day-to-day upkeep and an actionable pre-storm greenhouse checklist when gales are forecast.

Seasonal greenhouse inspection
Carry out quarterly checks of frame joints, screws, gaskets and base fixings. Inspect glazing seals and corrosion-prone areas at least once a year. In winter, check guttering, downpipes and the roof’s capacity for snow loading. After any high wind event, do a walkaround to catch minor damage before it grows.
Simple maintenance tasks that significantly reduce risk
Tighten loose fixings and replace corroded bolts with stainless or galvanised equivalents. Reseal glazing with suitable silicone or rubber gaskets and clear gutters to prevent pooling. Lubricate vent hinges and sliding doors, then test automatic vent closers and latches. Swap out torn polyfilm or cracked panels immediately; small cracks spread quickly under stress.
Pre-storm greenhouse checklist
- Secure doors and vents; lock or manually close roof vents if risk is high.
- Remove or secure loose items, pots and tools. Move potted plants away from glazing and walls.
- Fit external storm clips or batten down panels where applicable.
- Prepare an emergency kit: tarp, duct tape, extra fixings, a cordless drill and replacement gaskets.
- Have contact numbers for a local handyman or structural repair service to hand.
- For severe forecasts, consider moving valuable or tender plants to a sheltered site.
For easy ongoing management, keep a written greenhouse maintenance checklist near your kit and mark completed tasks. A short log after each seasonal greenhouse inspection helps track wear and predict when parts need replacing. Use the pre-storm greenhouse checklist as a quick reference whenever a gale warning appears.
Emergency Repairs and Insurance Considerations
After a gale, a calm, practical approach keeps people and plants safe. Prioritise safety and assess visible damage from a distance. If glazing is shattered or the frame tilts, do not enter until a professional confirms stability. Take clear photos and video of every damaged area, note dates and weather, then move salvageable plants to a dry, sheltered place.
Immediate steps after storm damage to prevent further loss
Start by cordoning off dangerous sections and covering breaches with tarpaulins or corrugated plastic to limit water ingress. Save broken glass and loose fixings as evidence for insurers. Clear debris carefully to avoid worsening structural issues. Keep a dated log of all actions and receipts for any emergency purchases.
Choosing and documenting for adequate insurance cover in the UK
Check whether your greenhouse sits under household buildings or contents cover, or whether a separate garden structure policy is needed. Many mainstream insurers limit cover for glass or outbuildings, so consider specialist horticultural insurers for large or commercial operations. Ensure policies include storm damage, accidental damage and loss of plants and equipment when required.
Document improvements such as stronger glazing, anchoring upgrades and professional installations. Insurers like Aviva, NFU Mutual and AXA frequently reduce premiums for demonstrable storm-proofing. Keep receipts, contractor contracts and a dated maintenance log to support claims and speed settlements.
When to call professionals for structural repairs
Contact a structural engineer or qualified builder if there is frame distortion, foundation movement or widespread glazing loss. Use Gas Safe engineers for heater or fixed-electrical work and consult RICS surveyors for major structural concerns. For screw piles or foundation repairs, engage specialist piling contractors who provide warranties and insurance.
For urgent stabilisation, accredited professionals via TrustMark or the Federation of Master Builders provide verified workmanship. Arrange written estimates before major repairs and photograph completed work for your files and future claims. Prompt, documented action helps with emergency greenhouse repairs and supports smoother greenhouse insurance UK claims.
Conclusion
While no greenhouse is completely immune to the worst of British weather, a clear, staged plan will make a meaningful difference. Combining wise siting with robust materials, secure foundations and thoughtful landscaping delivers the best outcome when making a greenhouse storm-proof. This balanced approach boosts greenhouse resilience UK and protects plants, equipment and investment.
Start with high-impact, low-cost actions: anchor frames, secure benches and move loose pots indoors. Then prioritise upgrades such as polycarbonate glazing, reinforced frames or a concrete base as budget allows. Keep records of works and follow building regulations for major alterations to ensure safety and insurability.
Practical habits complete the picture. Maintain a concise pre-storm checklist, assemble a basic emergency repair kit and plant permanent sheltering like hedging or a shelterbelt. For a storm-proof greenhouse summary: assess your site, fix the urgent vulnerabilities, plan staged improvements and consult reputable suppliers or structural professionals for any work beyond DIY skill.
FAQ
What does “storm-proof” actually mean for a greenhouse?
Storm-proofing is a spectrum, not an absolute. It means reducing the likelihood of structural failure, protecting plants and equipment during severe weather, and ensuring quick recovery afterwards. Objectives range from basic operational resilience—securing loose items and vents—to full structural resilience including reinforced frames, robust foundations and high-spec glazing.
Which UK weather hazards pose the greatest threat to greenhouses?
In the UK the main threats are high winds and gales, driving rain, hail, heavy snow loads and rapid temperature swings. Coastal and exposed upland sites face higher wind risk. Notable events such as Storm Eunice (2022) demonstrate how intense gusts can uplift lightweight structures and shatter glazing.
How should I assess my site’s exposure to wind?
Use local wind maps and Met Office records, observe prevailing wind directions, and study Ordnance Survey contours for channel effects. Note nearby sheltering features—buildings and hedges—and perform simple exposure tests by observing wind flow at different times. Prioritise risks by probability versus consequence to decide what to address first.
Which glazing is best for storm resilience: polycarbonate, glass or horticultural film?
Multiwall polycarbonate offers a strong balance of impact resistance, insulation and light weight—good for windy sites. Toughened or laminated safety glass has excellent light transmission and longevity but needs a stronger frame and base. Horticultural film is low-cost and temporary; it tears more easily in severe weather and is best for seasonal use.
What frame material should I choose for a windy site?
Galvanised steel provides the greatest strength and rigidity for larger or commercial greenhouses. Aluminium is corrosion-resistant and low-maintenance, suitable for moderate exposure if sections are robust and anchoring is strong. Treated timber can be attractive and thermally efficient but requires maintenance and larger sections to resist uplift and racking.
How important are foundations and what options exist?
Foundations are crucial. A reinforced concrete base offers the most rigid platform and anchor capacity for heavy frames and glass. Ground anchors or augers are economical for small-to-medium units and effective if sized to soil type. Screw piles (helical piles) are a specialist option where concrete is impractical or on sloping ground.
How do I anchor a greenhouse correctly?
Follow manufacturer guidance for anchor spacing—corners and midpoints are commonly required. Use galvanised or stainless through-bolts and brackets rather than simple screws. Match anchor depth and type to soil conditions: sandy soils need deeper anchors. Ensure base-to-frame connections are strong and corrosion-resistant.
Will planting hedges or trees help protect my greenhouse?
Yes—well-placed, porous shelter such as mixed native hedges reduces wind speed gradually and lowers turbulence. Plant hedges 10–20 metres windward for effective shelter. Trees can help but must be sited to avoid shade, root competition and the risk of limb fall. Bear in mind hedges take years to mature, so plan ahead.
What temporary measures should I take when a gale is forecast?
Secure doors and vents; lock down automatic venters and close roof vents manually if necessary. Remove or secure loose pots, tools and equipment. Apply storm clips or batten down panels where available. Prepare an emergency kit with tarpaulin, extra fixings, a cordless drill and duct tape, and move valuable plants to a safer spot if practical.
How should I organise internal fittings to reduce damage risk?
Bolt benches to the base or use sturdy brackets, keep heavy items low, and strap shelving with ratchet ties. Anchor large pots and secure tools in lockable storage. For valuable plants, use internal mini-shelters or padded trays and consider movable trolleys to shift specimens quickly.
What routine maintenance reduces storm vulnerability?
Conduct quarterly checks of joints, screws, gaskets and base fixings; annually inspect glazing seals and corrosion-prone areas. Tighten loose fixings, replace corroded bolts with galvanised or stainless versions, clear gutters, lubricate moving parts and replace damaged panels promptly to prevent defects worsening during storms.
What immediate steps should I take after storm damage?
Prioritise safety—avoid unstable structures and broken glass. Photograph and video all damage before moving items for insurance. Apply temporary covers to limit water ingress, move valuable plants to dry areas and retain fragments of glazing as evidence. Contact professionals for major structural issues.
Is my greenhouse covered by typical household insurance?
Not always. Some household buildings or contents policies include garden structures but often with limits on glass or outbuildings. Check policy wording; commercial growers may need specialist horticultural insurance. Document improvements and keep receipts and maintenance logs—insurers may reduce premiums where storm-proofing measures are in place.
When should I call a professional rather than attempt DIY repairs?
Call a structural engineer or qualified builder if there is frame distortion, foundation displacement or large glazing loss. Use RICS, TrustMark or FMB accredited contractors for major repairs. For electrical or heating faults, engage Gas Safe registered engineers or qualified electricians. Specialist piling or foundation remediation should be handled by experienced contractors with warranties.
What are cost-effective first steps for storm-proofing on a tight budget?
Start with high-impact, low-cost measures: install ground anchors, strap down benches and pots, apply storm clips and secure vents. Add inexpensive external windbreaks or temporary screens and follow a seasonal inspection regime. These simple actions substantially reduce immediate risk while you plan longer-term upgrades.
How can I plan resilience over 5–10 years?
Create a staged plan: inspect each season, prioritise urgent fixes, budget for incremental upgrades (better glazing, stronger anchoring, concrete base) and factor inflation and replacement costs. Record works and receipts to support insurance claims and review the plan after significant weather events.
Are there UK suppliers or products you recommend for robust glazing and fittings?
For multiwall polycarbonate consider UK brands such as Brett Martin and Palram products sold through Garden Trade suppliers. For fittings and fixings choose galvanised or stainless steel hardware and reputable greenhouse manufacturers that publish load ratings. Seek suppliers who provide wind-load data and installation guidance for the UK climate.
How can I balance ventilation and storm resistance?
Prefer roof vents that help equalise internal pressure rather than large side vents which act as sails. Fit automatic vent closers with lock-down options and ensure vents can be closed manually in severe weather. Regularly maintain hinges and latches so vents seal properly when required.
