Our 6mm solid polycarbonate sheet is a transparent polycarbonate sheet with UV protection on both sides offering excellent weathering properties. With its excellent impact resistance, it is ideally suited to a wide variety of building and construction applications.

Although mainly used in flat applications, solid polycarbonate can be easily cold formed into gentle curves which make it ideal for skylights, covered walkways, barrel vaults etc.

Solid polycarbonate is thermoformable and can be heat formed into the desired geometry whilst retaining the UV resistant properties for weather resistant applications.

UV Protection

Our 6mm solid polycarbonate sheet has proprietary UV protected surfaces, giving excellent durability to outdoor weathering. This superior UV resistance and toughness of our solid polycarbonate is backed by a 10 years limited warranty against yellowing, loss of light transmission and breakage.

Steel Ball Impact Test

Our 6mm solid polycarbonate sheet meets the highest impact performance required by the European Norm prEN356 for security glazing. A steel ball of 4.11kg with a diameter of 100mm is dropped freely from different heights onto the glazing specimen. The steel ball must impact the specimen 3 times. Our solid polycarbonate reached the highest standard required by the test at a thickness of 5mm and above.

Fire Performance

Solid polycarbonate has good fire behaviour characteristics, and receives high ratings in several major European fire performance tests. Our solid polycarbonate sheet achieves a class 1Y rating to BS476 part 7 surface spread of flame.

Related FAQs

1. What is the minimum pitch for a polycarbonate roof?
Never install polycarbonate flat. Our standard glazing systems require a minimum pitch of 5° to ensure water can run off the roof and to eliminate ‘puddling’. Our Multi-Link-Panel modular system should be installed with a minimum 10° pitch. Contact us if you require clarification.
2. Can you walk on polycarbonate sheet?
Polycarbonate has been tested against UK wind and snow loads and we can supply you with recommended glazing centres for each thickness of polycarbonate. However you should never walk directly on polycarbonate sheet. A crawling board or similar should be placed across at least two structural supports of the roof. We can manufacture aluminium framed polycarbonate panels which have been tested for non-fragility to ACR(M)001:2014 – this does not mean you can walk on the polycarbonate but gives added resistance to accidental falls.
3. How do you clean polycarbonate sheet?
Gently wash the sheet with a solution of mild soap and lukewarm water, using a soft, grit free cloth or sponge to loosen any dirt or grime. Rinse over with clean water to remove any residue. NEVER use a proprietary glass cleaner.
4. What is the fire performance of polycarbonate?
Polycarbonate has good fire behaviour characteristics and receives high ratings in several major European fire performance tests including EN13501. Always check with the Twinfix sales office for current classification, at the time of writing most variants achieve a class1Y when tested against BS476 part 7 surface spread of flame.
5. How does UV affect polycarbonate?
Solar radiation has a particularly harmful effect upon materials that are not protected. Many variants of multiwall polycarbonate have a unique proprietary UV-protected surface on one or both sides, giving excellent resistance to outdoor weathering. This unique protection ensures long-term optical quality under intensive UV exposure.
6. Polycarbonate is virtually unbreakable, so isn't polycarbonate glazing non-fragile?
No, in many canopies that use multi-wall or solid polycarbonate glazing, the glazing is simply clamped into a glazing bar system that just holds these sheets in place. Whilst the sheet itself might not break, a falling object, (and in some cases even a strong wind), can flex the sheet and force it out from between the glazing bars. If someone were to trip on such a roof, they could fall through, endangering themselves and anyone underneath. Remember..... just because it doesn't break doesn't make it non-fragile.
