Free Cavity Wall Insulation

Cavity wall is where exists a gap in between internal and external walls. Almost all houses built during or after 1950’s have empty cavity walls. These walls results in heat loss which increases the energy usage of the houses to keep them warm. Cavity wall insulation is injected in between these walls by drilling a series of unnoticeable holes. These holes are then sealed with cement after filling in adequate amount of insulation. The whole process can take up to 1-3 days depending upon property size
