One of the major benefits for developers using offsite construction for high volume housing is it significantly increases the speed of the build by reducing build time on site. Work is progressing at a rapid speed for this happy developer using our Reflect® 140 wall system which is factory insulated and closed on the inner face with an airtight membrane and service battens. The combination of membranes and insulation are used to optimise performance and minimise cost. Factory fitting the airtight membrane and battens greatly reduces site works.
