Coventry, UK -- Insulation company Innovaré Systems has supplied its i-SIP (structural insulated panel) system to a social housing scheme in the south of England.
The panels were used in the construction of certified Passivhaus homes. It was the first time that Innovaré's i-SIPs were used to meet the global energy standard, the company said in a 17 Aug announcement.
Innovaré said early adoption of the i-SIP system by the construction team at Bryce Lodge in Horsham "established the thermal envelopes for the scheme which in turn informed design considerations that affected the planning requirements."
This allowed the company to develop a specific product that met the air permeability requirements of Passivhaus 0.6m3/m2/hr at 50pa as well as providing U values at 0.10 W/m2K with minimal cold bridging, Innovaré of Coventry, UK, said in the announcement.
In addition to providing 12 Passivhaus units at Bryce Lodge, Innovaré also supplied i-SIP structures for the remaining 26 units built to the Code for Sustainable Homes level 5 standards. Those units are constructed from a slightly different i-SIP system with U values of 0.13 W/m2K, where the thermal bridging is less of an issue, according to Innovaré.
The company added that building the homes at the same location to two different standards of sustainability allows performance in use to be compared directly. Saxon Weald, who provide social housing in the area, aim to use information gathered to inform future decisions about which energy standard to use.
