We offer a range of solutions for the offsite market, for the external building envelope as well as for internal walls, floor cassettes and ceilings. Providing technical solutions for MMC across residential and commercial schemes, our products are regularly used to ensure:

The membranes used from Protect tick all the boxes of performance for this unique café development. As the building is sited in a particularly harsh and exposed coastal climate, it was critical that the outer membrane Protect Thermo Extreme offered a primary line of protection to the whole of the external wall during the construction as well as providing enhanced thermal resistance to meet our target U-value. Combined with Protect VC Foil Ultra, which we have tried and tested over many years, this ensured condensation risk was managed and controlled.
