EJOT innovates to drive up soffit insulation standards

2 mins

EJOT’s new DDS-Z fastener range holds the key to installing much greater depths of soffit liners with the smallest embedment depth, helping architects and clients to dramatically improve the thermal performance of buildings, as well as acoustic and fire insulation standards.

Doing so enables car parking to be created below ground or at ground level where residential or commercial space is contained above—hence the need for high insulation standards using soffit liners. However, the increasingly high thermal standards now being sought here in the UK have given rise to the use of much greater depths of mineral fibre insulation. This demands significantly longer fasteners to drive through the multiple layers of insulation and anchor effectively into the concrete substrate—all with a minimal embedment depth. EJOT UK has responded with the DDS-range of steel screws featuring a duplex coating and self-tapping thread for reliable fastening, with only a 25 mm embedment into cracked and non-cracked concrete.

This range of high-quality self-tapping fasteners is designed specifically for the attachment of ceiling insulation and acoustic boards to concrete soffits, where the goal is to bring uninsulated floor structures up to the thermal requirements of the latest building regulations and beyond.
