Reflect early rather than regret later

Modern industrial Rooflight systems form an integral part of the overall roofing system. Once correctly installed they complete the roof and perform the valuable job of bringing natural daylight into the building.

The level of daylight that a rooflight system can give depends on the type of system, the materials used to construct it plus the quantity and position of the rooflights installed.

Looking just at the construction of rooflights it’s important to understand that regardless of whether the rooflight is made from glass, polycarbonate or GRP the performance is affected by the number of layers in the rooflight. The more layers the greater the level of reflectance which in turn causes less light to be transmitted into the building. If this isn’t recognised, then the light level in the building won’t be as expected and increased artificial lighting will be needed to compensate.

 

Remember the ‘Walkie Talkie’ building? That’s an excellent example of what can happen if reflectance isn’t understood.

 

 

 

 

 

 

 

To ensure that specifiers and building owners can rely on the technical data being quoted for their rooflights, Hambleside Danelaw asked the National Physical laboratory (NPL) at Teddington to independently measure the light transmission data and ensure that data quoted is totally reliable.

Hambleside Danelaws innovative approach to product development saw the launch of our patented Zenon Insulator core which significantly outperforms traditional rooflight insulation cores in regard to light transmission. The honeycomb like system transmits significantly more light into the building, which will reduce the need for artificial lighting resulting in lower CO2 emissions and operational energy costs.
