Multiwall polycarbonate glazing sheets are a high quality product produced in 'clean-room' conditions which helps to ensure that it retains this quality.

It is an ideal roof glazing material that offers remarkable impact resistance and long-term weather durability.  It is virtually unbreakable and will withstand storms, hail-stones, wind, snowfalls and ice formation - as well as prolonged hot sunny weather.  It performs extremely well in temperatures as low as -40 degrees C and as high as +120 degrees C.

In addition, it has high levels of light transmission and superb heat insulation characteristics, both of which offer cost savings by conserving energy - important when we are all trying to cut down on carbon emissions.  Multiwall polycarbonate is also very light in weight compared with glass, making it much easier to lift on to a roof.  Because it is so tough there will be no breakages during installation, and being light in weight means that it doesn't need heavy structures to hold it in place.

Opal or bronze tints, and a Venetian pattern (a white stripe), are available for use where levels of light transmission and/or solar heat gain need to be restricted, such as applications on a south or west facing roof.

The product features a proprietary UV coating that is designed to protect the sheet against the degrading effects of ultra-violet radiation in natural sunlight.  UV will not be transmitted through this glazing, making it an ideal choice for playground canopies used to protect children from these harmful rays.

Typical applications where multiwall glazing is used include:

• Industrial and commercial rooflights
• School playground canopies and covered areas
• Stadia roofing
• Railway station and platform canopy roofing
• Commercial greenhouses
• Swimming pool roof covers
• High level vertical glazing
• Smoking shelter roofing

It is also widely used in the domestic market for:

• Conservatory roofing
• Car ports
• Patio covers
• Sun room roofing
• Cloches
• Home greenhouses (where its unbreakability provides safety to young, playing children)

Twinfix Service

We will cut your multiwall glazing to size: even to shape as long as we have all the information to work to.  After cutting, we will blow the flutes free of swarf and dust.  We will then tape the ridge end of the sheet with an aluminium blanking tape and the eaves end of the sheet with an anti-dust breather tape (grey in colour).  This helps to keep them free from dust and crawling insects in the future. 

And, when it comes to delivering your multiwall glazing, we don't believe in using an outside haulier as we don't think they take enough care, and your sheets could get damaged.  We only deliver this product on our own vehicles, with our own team of drivers, who know how to handle it correctly.  You can, of course, collect direct from our Warrington facility, should you wish.
