Construction membranes deliver hidden protection and thermal efficiency benefits


A combination of wall construction membranes from Glidevale Protect has been installed across two social housing developments, designed and built by modular construction specialists Connect Modular, part of The Wee House Group.

The mix of membranes used included the reflective, low emissivity TF200 Thermo for external walls, improving thermal efficiency as well as non-reflective TF200 to provide water resistance and a secondary line of defence after construction, minimising the risk of interstitial condensation. Protect VC Foil Ultra, the reflective air and vapour control layer was also used on the warm side of the insulation to again manage condensation risk and improve energy efficiency.

The first development using Glidevale Protect membranes completed in May 2021 for Mull and Iona Community Trust, with modular homes built in Connect Modular’s factory in Cumnock, Ayrshire and installed across two sites in the remote location of Ulva Ferry on the Isle of Mull, required to meet acute housing need on the island.

Now on site, Connect Modular is working with Riverside Scotland, part of the Riverside Group, in delivering 63 affordable homes in Dundonald, South Ayrshire, representing the largest affordable modular housing development in Scotland. With a blend of different house types all featuring Glidevale Protect products, the first homes are scheduled to be ready for occupancy by the end of 2021. The scheme has taken advantage of the benefits of offsite construction for quicker delivery, with all homes expected to be built, put in place and occupied in around a year.

Jennifer Higgins, Managing Director of The Wee House Group commented, “Glidevale Protect is a reputable manufacturer and supplier of high quality manufactured membranes. These were ideal to incorporate into our timber frame panels being produced offsite in our factory for the Isle of Mull and Dundonald schemes. With impressive aged thermal resistance values for reflective products, this helped to generate low U-values and meet improved energy efficiency needs for our clients, helping to retain energy within the structure and reduce consumption.”
