FIRE

GIS Cavity Duo Socks are manufactured with Knauf ECOSE Rock Slab, encased in recycled plastic. Knauf ECOSE has a EUROCLASS A1 fire rating, tested to BSEN13501-1.  We test our socks using the latest BSEN1366-4 methods, for cavities up to 300mm wide, as per the BMT/FE/IF/15078 report, fitting them between substrates with equal or higher fire ratings than Duosocks to meet Approved Document B requirements.

ACOUSTIC

GIS Duo Cavity Socks are effective sound barriers that fulfill the generic requirements to prevent flanking noise transmission in external and separating wall cavities. They are in compliance with Approved Document E (2014) of the building regulations for England, Wales, and Ireland.

THERMAL

The socks have a thermal conductivity of 0.037W/mK. When installed, they provide an efficient perimeter edge seal, meeting building regulations L1A and L2A, as well as section 6 of the Scottish building standards.

COMPLAINCE

The fitting of GIS Duo Cavity Socks conforms to the requirements set out in Part E of the Robust Details scheme. Our socks meet E-WM 1-21 for masonry in separating and party walls, E-WT 1-4 for timber frame in separating and party walls, and E-FT 1-6 for separating floor applications.  Our socks comply with E-FC 1-14 for concrete in separating floor applications.
