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.
