Special remarks
It goes without saying that on any education project the fire safety performance of the product is a critical consideration. We were also looking for a solution that could help minimise any noise transfer in line with BB93. Finally, it makes a big difference if the insulation is also easy to work with, saves us time and doesn’t cause us any issues on site. Daniel Rowan, DPR Thermal
