Through-the-wall system opens doors to offsite for housebuilders

A complete wall system from Saint-Gobain is making construction solutions more accessible to small and regional housebuilders and contractors. EnveoVent is the first complete through-the-wall solution available from a single manufacturer.  

The Modern Methods of Construction (MMC) framework Category 2 panellised system is a fully tested, complete, ventilated and insulated structural wall with a choice of internal and external finishes, offering an alternative to traditional masonry construction. The system offers one warranty, one procurement route and one single point of contact, while improving build speed and efficiency. The solution has been designed for the social housing market, delivering speedier build schedules and warmer homes for residents. 

Saint-Gobain UK & Ireland CEO Mike Chaldecott said: “We are incredibly proud to be launching a complete wall solution that has been rigorously tested as a system to deliver the required levels of fire, acoustic and thermal performance. EnveoVent demonstrates our commitment to lightweight construction methods and our clear purpose to make the world a better home.” 

The EnveoVent solution has been piloted by Saint-Gobain and TR Partnership Homes at a Midland Heart housing association development of 12 social homes in Birmingham.  

Comprising a more sustainable, closed panel timber frame, the solution switches traditional masonry for timber, which has been shown to cut embodied carbon emissions by around 20%. The system also uses mineral wool insulation manufactured from up to 65% recycled glass and carries a U-value of 0.16 to 0.13W/m2K, depending on wall thickness, which exceeds the 0.18W/m2K required by the Future Homes Standard in 2025. 

Complete fire, thermal and acoustic performance testing has been carried out on the EnveoVent system, alongside fully detailed structural calculations. This meets requirements of the Building Safety Act 2022 for a golden thread of secure, easily accessible and accurate product information.
