Twinfix GW Polycarbonate: The innovative alternative to Georgian wired glass

One of the latest polycarbonate glazing variants available from Twinfix is a 6mm solid sheet that combines the appearance of Georgian wired glass with all the material benefits of polycarbonate. This lightweight glazing has the same sort of dimpled surface as Georgian wired glass – and this should always face the inside of a building when installed – but it is incredibly tough and durable and will withstand all that the British weather can throw at it without cracking and breaking.

Having been approved for use in Grade II listed buildings, GW Polycarbonate is now being installed at traditional 600mm centres as rooflight glazing in many refurbishment projects. Whether it’s a railway station canopy or overhead glazing in a swimming pool this innovative 6mm polycarbonate glazing looks very similar to traditional Georgian wired glass, but provides the much higher levels of roof safety required nowadays, especially in public buildings. It is also less than half the weight of 6mm glass, so its use can help extend the fabric of an older building.

It may be installed using one of the Twinfix range of traditional glazing bars or where the project needs to conform to the ACR[M]001:2014 drop test as described in the HSE document HSG33 it is available pre-glazed into the Twinfix Multi-Link-Panel NF (non-fragile). These ‘fix and link’ pre-fabricated modular rooflight panels have a strong, lightweight and rust-resistance aluminium frame that is quick and easy to install.

The use of GW Polycarbonate rooflights fits in well with today’s need for future proofing as this product is virtually unbreakable, requires little maintenance and may be recycled at the end of its long life span.
