25mm Multiwall Polycarbonate Sheets

Clear, Opal and Bronze tints.

Lightweight, tough and thermally efficient roofing panels!

With upto 200 times impact strength of glass, polycarbonate sheets, offer are a safe, long-lasting roofing choice and a great option for conservatory roofs, canopies, atriums, industrial rooflighting and many more applications.

These 25mm sheets are great insulators that reduce condensation and can diffuse light. This multi-wall polycarbonate wont let you down when consideration energy conservation too - it can be more energy efficient and upto 50% cheaper than glass of a comparable thickness!

Features and Benefits

	UV Resistance - minimises long-term yellowing
	High resistance to impact - resistance to breakage
	Super thermal efficiency - triplewall and fivewall
	Robust yet lightweight - fraction of glass weight
	Fire safety - Class 1 Spread of Flame Protection
	10 year warranty - light transmission is guaranteed

Let Truly do the preparation for you - for polycarbonate to work effecitvely and have a long life, it's vital that any bits of dust and plastic are blown from the flutes once cut. Not only do we cut to size for you, we then ensure that the flutes are clear and the ends are taped. We save you time and money!

Choosing Polycarbonate

Beyond simply appearance, there are other considerations when choosing the best polycarbonate for your application. The Colour Tint, Thickness and Sheet Size are key factors explained below.

Polycarbonate Colour Tint

ClearMaximises daylight

High level of light transmission provides greater heat build up. A conservatory would be bright and light - even on the darkest winter days. A good choice for colder spots and ideal for industrial and commercial greenhouses.

OpalSoft diffused light

Allows light into a conservatory or building to keep it bright but reduces solar gain concentrating on one area. So, eliminates uncomfortable hot-spots. Provides privacy and creates softer light quality.

BronzeKeeps things cool

Lower levels of light transmission and shading co-efficiency makes Bronze effective at limiting the amount of light and minimising glare. Also reduces heat build up, so it's popular for sunnier spots as it can help keep room cool.

Polycarbonate Sheet Thickness

If replacing individual sheets then you may wish to purchase the same thickness as the others. Alternatively, when whole roofs are being replaced, it may be an opportunity to upgrade to thicker sheeting for greater thermal efficiency and sound-proofing. But be sure that the increased thickness is compatible with your roofing system.

Polycarbonate Sheet Size

These sheets are available in various widths and lengths to save time preparing the sheets, save money and minimise wastage. Please note that due to the thermal expansion of fitted sheets, a little space should be available on the ridge and glazing bar sides (see our Polycarbonate Advice Sheet for more information). Width and Length options are as follows.

Product Comparison - Thermal Efficiency

The thermal efficiency of glazing material is described using terms such as 'U-value' and 'Solar Heat Gain'. These measurements provide a means of comparing one material against another and the following table illustrates the performance of these polycarbonate sheets.

* Weight is measured in (kg/m²). ** Structure is described as follows: TwW = Twinwall, TW = Triplewall, TWX = Triplewall X, FW = Fivewall, FWX = Fivewall XX.
