THERMOFLOC VSD MEMBRANE
A high performance variable vapour resistance barrier
Thermofloc Variable Surface Diffusion (VSD) membrane is an intelligent membrane which acts as a high performance vapour barrier providing air tightness. Further allowing effective variable vapour resistance in a building.
Use Thermofloc VSD Membrane internally as an air tight barrier and vapour control layer for internal walls and roof linings. Moreover only use Thermofloc VSD Membrane on the warm side of the insulation.
In addition reinforced for increased tear resistance use it in conjunction with most insulation systems including THERMOFLOC cellulose insulation.
