Fireshield® vapour permeable membrane, which is designed specifically to improvethe fire protection behind cladding has been chosen for a new Science Centre at Bevington Primary school in the Royal Borough of Kensington and Chelsea,
London.
The project includes a brand new Science Studio, plus before and after school club buildings. SIP Build UK was appointed as frame subcontractor for the project and chose the Fireshield membrane as part of the SIPS panelling system. Chris Duckworth from SIP Build UK explains: “We chose Fireshield as it provided the project with a number of really important benefits. Fireshield is a high-performance breather membrane which enables us to achieve the requirements in terms of fire protection without compromising on vapour control.
Fireshield was also ideal because it is easy to use and allowed us to achieve the requirements in one process, using just the membrane, rather than the typical approach of two, cement board and a membrane.”
Fireshield is the culmination of leading research to produce a vapour permeable membrane with a intumescent coated surface, which has a unique composition that actively reacts to help protect the materials underneath. The intumescent
coating helps protect the substrate by reducing the risk of fire taking hold and significantly reduces the formation of droplets and smoke.
The BBA Certificate awarded to Fireshield confirms that it has enhanced performance in relation to reaction to fire classification, will reduce the risk of interstitial condensation, and will have a life equal to that of the building in which it
is installed.
Fireshield is classified as Class B, s1 –d0 according to the Euroclass system, which classifies the reaction to fire performance of building products. The performance of Fireshield is in advance of the requirements of the current classification grading.
Fireshield complies with BS5250, BS4016 and NHBC requirements for vapour permeable walling underlays. It is installed and fixed to the substrate in the same manner as standard breather membranes using mechanical fixings. Applications include both commercial and residential buildings including apartments and student accommodation, as well as Rainscreen cladding and applications over 18m high.
