ROCKCLOSE® Insulated DPC

Combatting door and window heat loss 

If left uninsulated, as much as 20% heat loss can occur around door and window reveals. This results in both expensive heat loss and damaging exposure to moisture. ROCKWOOL ROCKCLOSE® fire resistant Cavity Closers work to effectively minimise thermal bridging at door and window reveals in cavity wall constructions.
