Home Product News Etex launches Thruwall system to streamline building envelope specification

Etex Building Performance has launched its new Thruwall system, a single solution for the building envelope.  It combines elements from the company’s three lightweight construction brands, Siniat, Promat and EOS Facades, to remove the need for project teams to procure three separate building products, saving them time, money and the need to review previously disparate performance data from materials providers.

The Etex Thruwall system is guaranteed under one 30-year warranty, providing regulatory compliance and assured technical performance for the construction supply chain and building users.  The non-loadbearing in-fill system combines Siniat’s Weather Defence external sheathing board, light gauge steel framing from EOS and internal wall linings, drawing on Promat’s expertise in passive fire protection.

It is the latest advanced system to be developed at Etex’s Innovation and Technology Centre in Avignon, France.  Designed specifically for multi-storey residential buildings, the one-stop solution can be adapted for the specific needs of projects, providing up to 120 minutes of fire resistance and sound insulation up to 50 Rw dB.  Each system is subjected to rigorous fire, acoustic, airtightness, weathering and mechanical tests.

Construction teams also benefit from Etex’s combined technical expertise, helping them to navigate specification details and ensure the system is installed correctly on site.

Simon Scrase, Business Development Manager at Etex Building Performance, said: “Until now there hasn’t been a system-based approach to the design of external building envelopes, forcing specifiers to rely on a fragmented supply chain and piece together performance statistics for different components.

“In a changing regulatory environment, Thruwall takes the headache away from the specification process and uncertainty about how different materials will work together to deliver a guaranteed level of performance.  Project teams can concentrate on more challenging aspects of their schemes, safe in the knowledge that Thruwall will live up to its promises, while building users have peace of mind that their homes will meet and even exceed building regulations.”
