Modular house builder uses new Winframer specification


Leaders at the modular house builder CoreHaus have specified Winframer, ISO Chemie’s thermal insulating and load bearing bracket support system, for the firm’s new designs. The development is to see Winframer units, along with Win2Wall multi-level sealing tape, supplied to CoreHaus, as part of the company’s five-year plan to produce around 1,000 precision engineered units a year, to deliver long-term energy cost savings.

Passivhaus-certified and fire rated for up to 30 minutes, Winframer is a prefabricated installation frame, manufactured to accommodate cavities up to 250mm. It is marketed as a product that allows windows to be supported independently from the face of the wall, regardless of any external cladding.

Dan Selby, CoreHaus’s managing director, said: “As a house designer, we are always looking at smarter ways to deliver low-carbon structures, which includes using sustainable technologies. ISO Chemie’s fit-and-forget products offer innovative solutions for effective window and door sealing, delivering measurable airtight, acoustic and thermal sealing benefits in the process.”

Nick Thompson, ISO Chemie’s technical consultant, added: “Using Winframer allows a cavity wall to be created outside the existing one. This can then be filled with insulation to massively improve thermal efficiency. As it’s also very thermally efficient and airtight, Winframer is proving to be an easy and cost-effective way to improve the quality of the modular properties.”

The composite Winframer brackets can bear heavy windows loads and bi-fold doors, its representatives have claimed, to provide ‘a reliable, strong and high-performance support frame’. Among the advantages of Win2Wall are its thermal performance. It is also weather tight to 600 Pa (Violent Storm Force 11) and is marketed as having excellent acoustic insulation properties.
