Innovative membranes deliver thermal efficiency and cost savings for off-site construction
With the ongoing need to build more housing to meet Government targets alongside the increased requirement for energy efficient homes, modern methods of offsite construction (MMC) are being seen as the panacea to address the housing shortage.
Protect Membranes, a division of Building Product Design Ltd alongside its sister company Glidevale, is a UK producer of construction membranes which are designed for use in offsite construction.
Using innovative reflective membrane technology, Protect VC Foil Ultra and TF200 Thermo products are specifically designed to enhance the thermal performance and airtightness of a timber frame panelled wall construction, delivering low emissivity and ensuring radiant heat is reflected back into the structure, minimising absorption and energy transfer. Forming part of Protect’s comprehensive range of membranes for the construction and roofing markets, when installed together in a cavity wall with a still airspace, VC Foil Ultra and TF200 Thermo provide a cost effective solution to enhance the thermal efficiency of a building by up to 25%* (based on 0.035 λ insulation). This contributes to the house structure, meeting demanding U-value specifications whilst offering the opportunity for cost savings on the wall build. Both membranes feature an easy to understand colour coding system to guide customers on correct installation: red print on VC Foil Ultra, the vapour control layer for use on the warm side of the installation and blue print on TF200 Thermo, a breather membrane to be formed on the outside / cold side of the installation.
Traditional masonry construction can also benefit by using Protect VC Foil Ultra and a service void to give an improvement on the U-value result, with no need to parge coat the blockwork, saving time and money, an important driver in the MMC sector.
John Mellor, Product Manager for Protect Membranes said, “Based on our technical calculations, using Protect VC Foil Ultra and TF200 Thermo within a timber frame construction with a still airspace cavity could provide a saving of over £750 per average two-bed property, whilst still achieving a low U-value of 0.21. This represents a tremendous potential for housing associations and housebuilders to reduce build costs, and our technical team is on hand to provide custom detailing and U-value calculations, indicating potential savings by request”.
