Polycarbonate sheets are ideally suited to many roofing projects, such as conservatories, car ports and covered walkways, combining the strength of polycarbonate with air pocket insulation, within a lightweight sheet. The sheets have many excellent properties including:
- Non-flammability - Sunlite sheets are self-extinguishing and do not emit toxic gases when subject to flame
- Impact resistance - Polycarbonate is significantly tougher than glass, styrene, acrylic or PVC, and so resistant to falling roof tiles or malicious damage, for example
- Heat and noise insulation - heat gain or loss is minimised by the air cells within the sheet, giving much better results than single walled, corrugated or solid flat sheet
- Durability - Sunlite sheets come with a 10 year limited warranty
- High light transmission - up to 82%, depending on thickness and tints
- Protected surfaces - sheets are supplied with protective film on both sides (printed film indicating the side with UV coating, to be installed outwards). The film must be removed prior to use
- Workability - Sunlite sheets can be cut with a handsaw, jigsaw or bandsaw. If using a circular saw we recommend gloves and protective eyewear are worn. A fine tooth high speed steel saw blade gives best results
Please also note that Polycarbonate sheets need careful handling as edges can be sharp, and that they are subject to thermal movement, so allowance for this should be made when positioning any fixing through the sheet. For comprehensive advice and information on these sheets, please refer to the PDF "Multiwall Technical Guide" on this page. This covers light transmission, physical properties, curving radius, slope, wind and snow loadings, installation, sheet spans, connecting and fastening, thermal expansion, handling and storage, cleaning, safety, cutting, drilling, bonding and sealing. We recommend that you read this before purchase.
Sunlite sheets can be supplied in 3 standard finishes, achieved by tinting during production:
- Clear for projects where light is most important, such as car ports
- Opal for matching to white PVC conservatories and similar
- Bronze for matching with hardwood or brown PVC conservatories
Tubeway supply the two common designs of polycarbonate roofing, Twinwall and Multiwall, along with accessories required for installation, details of which are listed below - to discuss your requirements further please contact us with your Twinwall / Multiwall Polycarbonate queries.
TWINWALL POLYCARBONATE SHEET
Sunlite Twinwall polycarbonate roofing sheet is available in 3 sizes. Clarity is very good, with the Clear sheets letting around 80% of light through, whilst the Bronze and Opal sheets are more opaque.
Although Twinwall sheets are available in large sizes, they may need special delivery arrangements. Please contact us to confirm these and to discuss any other Twinwall Polycarbonate Sheet requirements.
4mm and 6mm Twinwall Polycarbonate
Sunlite Twinwall’s smallest sizes, these lightweight sheets are only available in Clear. They can be supplied in various sheet sizes, all based on cut downs of 3660 x 1830mm or 2440 x 1220mm, although because they are not rigid, large sheet sizes may be difficult to handle or install.
Prices are based on 4mm = £8.70 per square metre and 6mm = £12.40 per square metre.
10mm Twinwall Polycarbonate.
Sunlite 10mm is a more popular size, combining clarity, lightweight design and more rigidity than the thinner Twinwall sheets. It can be supplied in sheets of Clear, Bronze and Opal as large as 7000 x 2100mm, although smaller metric sheets are much easier to handle and deliver.
Prices are based on 10mm = £16.80 per square metre for all shades.
For 10mm Twinwall Accessories, please see the section below.
MULTIWALL POLYCARBONATE SHEET
Sunlite Multiwall polycarbonate roofing sheet is available in 2 sizes. Clarity is reasonable, with the Clear sheets letting around 60% of light through, with the Bronze and Opal sheets being more opaque. Although Multiwall sheets are available in large sizes, these may also need special delivery arrangements. Please contact us to confirm these and to discuss any other Multiwall Polycarbonate Sheet requirements.
16mm Multiwall Polycarbonate
Sunlite 16mm Multiwall is a popular product, strong and rigid, with excellent insulation properties from its multiple air pockets, keeping warmth in during winter and excessive heat out in summer. It is available in sheets of Clear, Bronze and Opal of up to 7000 x 2100mm, although smaller sheet sizes are easier to handle and deliver.
Prices are based on 16mm = £26.20 per square metre, for all shades.
For 16mm Multiwall Accessories, please see the section below.
25mm Multiwall Polycarbonate
Sunlite 25mm provides scaled-up benefits of the Multiwall design, with better thermal insulation but without sacrificing much clarity. It is available in the same Clear, Bronze and Opal tints, and the same sheet sizes as the 16mm Multiwall sheet. In addition to these standard shades, we can now offer 25mm "Bronze on Opal", which is one layer of either shade sandwiched together. This is usually installed with Opal on the inside and Bronze on the outside. Also available is Opal "Heatshield" 25mm Multiwall, offering solar control as infrared sunlight is blocked by additives within the sheet, but high light levels are still let through. Protection is permanent and Opal Heatshield is UV protected on both faces. Tubeway will be pleased to receive your 25mm Multiwall Polycarbonate enquiries.
Prices are the same for standard shades, based on 25mm = £34.30 per square metre. Bronze on Opal and Opal Heatshield options are 25mm = £37.30 per square metre.
35mm Multiwall Polycarbonate.
35mm Multiwall is the largest size available, in sheet sizes the same as the 16mm and 25mm sizes, up to 7000 x 2100mm. Please note that the range of accessories for 35mm Multiwall is not as wide as smaller sizes. Standard Clear, Bronze and Opal tints are based on 35mm = £40.80 per square metre whilst Bronze on Opal and Opal Heatshield options are 35mm = £44.30 per square metre.
