Why Choose 10mm Multiwall Polycarbonate Roofing Sheets?
Our 10mm twin wall polycarbonate sheets are the most popular choice for pergola roofing, carports, lean-to roofs and conservatories in Ireland. Combining exceptional impact resistance with superior thermal insulation, these sheets offer 200 times the strength of glass with 82% light transmission and a co-extruded UV protective layer on the outer surface for long-lasting performance.
Applications
Pergola and Patio Roofing: The most popular use for 10mm multiwall polycarbonate in Ireland. Creates a weatherproof outdoor space that retains natural light - ideal for pergolas, verandas and covered patios where a bright, comfortable feel is important.
Carports and Lean-To Roofs: Strong enough to handle typical Irish weather loads while remaining lightweight and straightforward to install. The 700mm maximum rafter spacing suits the majority of standard domestic carport and lean-to structures.
Conservatories and Sunrooms: Good thermal performance keeps glazed spaces comfortable year-round without the weight or cost of glass.
Greenhouses: The twin wall structure traps an insulating air layer, retaining heat during cooler months while diffusing direct sunlight - creating good growing conditions without harsh direct light.
Commercial Canopies and Walkways: Suitable for skylights, covered entrances and canopy structures on retail and commercial buildings where durability and light transmission are both required.
Need greater insulation or longer spans? For roofs requiring higher thermal performance or wider rafter centres, consider our 16mm triplewall or 25mm 7-wall polycarbonate sheets.
Benefits
Impact Resistance: 200 times stronger than glass and virtually unbreakable under normal conditions - far safer and more practical than glass for roofing applications, including resistance to hail and wind-blown debris.
Light Transmission: 82% light transmission creates bright, naturally lit spaces. The twin wall structure also diffuses direct sunlight, reducing glare while maintaining a comfortable indoor environment.
Thermal Insulation: The hollow twin wall construction provides a natural insulating air gap, reducing heat loss compared to single-skin glazing - particularly beneficial in Ireland's climate.
UV Protection: Co-extruded UV protective layer on the outer surface blocks over 98% of harmful UV rays, preventing yellowing and loss of strength over time. Sheets must always be installed with the UV protected side facing outward.
Lightweight: Far lighter than glass, reducing structural load on the supporting framework and making on-site handling and installation significantly easier.
Installation Note: When fitting 10mm multiwall polycarbonate on a roof, maximum rafter spacing must not exceed 700mm. Always install with the UV protected side facing outward and ribs running vertically or up-slope. Seal the top edge with solid aluminium tape and use a vented U-profile at the bottom edge to allow condensation to drain. Full fitting advice in our multiwall polycarbonate installation guide.
