Cavity Wall Insulation


It is estimated that 35% heat loss occurs through un-insulated walls, resulting in wasted energy and money.  For cavity wall insulation, a series of small holes are drilled on the outside of the house, through which the bead is injected with an adhesive that binds the beads together. This forms a layer of insulation that has no joints and accesses every section that conventional insulation board cannot cover. The holes are concealed and revamped using sand, cement and dye.
