A new rooflight has achieved 60 minutes fire integrity and insulation after being tested by BRE. Glass manufacturer Pilkington collaborated with NuLite Ltd, designer, manufacturer, installer and renovator of all types of rooflights, to test the new NL604 (C) fire-resistant rooflight which contains 23mm Pilkington Pyrostop 60-101.
“We use a number of Pilkington products in a variety of our roof lights, glass pyramids and lantern lights, so we were confident Pilkington Pyrostop would pass our stringent requirements for this new product, said Bill Harris, managing director of NuLite Ltd. The tests were very successful, achieving greater fire resistance than anticipated – 80 minutes integrity and 64 minutes insulation.”
Mike Wood, Global Fire Protection Consultant, Pilkington, said: “We test our fire resistant glass range in a number of different scenarios so specialist fire glaziers and specifiers know which combinations of products are the most suitable to use together. This test was carried out using the principles of BS 476 part 20 which includes glazed screens, floors and walls, and we are very pleased to be working with NuLite Ltd on this new product.”
The Pyrostop range is a family of clear, laminated, fully insulating fire and impact resistant glass that offers fire protection while maximising natural light and visibility. In the event of fire it turns opaque, providing both the integrity requirements of a barrier to hot gases and flames, as well as very effective insulation from the heat of a blaze. Depending on the thickness, it also provides impact protection up to Class 1 of BS EN 12600.
