AIR PERMEABILITY CLASS 4 FOR SECTIONAL DOORS
Tekta are now offering our Rollashield SD sectional doors with the new ThermalSafe panels from Kingspan – offering an industry-leading air-permeability of Class 4.
There are two critical aspects to the Thermal Performance of a door in order to meet Building Regulations and reduce energy wastage, these are:
1) The thermal conductivity performance (U-Value) of the door, and
2) The air-tightness (permeability) performance of the door.
