About Heat & Flow - Mitcham - Surrey - CR4. How is cavity wall insulation installed? Cavity wall insulation. Cavity wall insulation is used to reduce heat loss through a cavity wall by filling the air space with material that inhibits heat transfer.
This immobilises the air within the cavity (air is still the actual insulator), preventing convection, and can substantially reduce space heating costs. A wall that has had cavity wall insulation installed (after construction), with refilled holes highlighted with arrows. During construction of new buildings, cavities are often filled with glass fibre wool or rock wool panels placed between the two leaves (sides) of the wall, but many other building insulation materials offer various advantages and many others are also widely used. For existing buildings that were not built with insulated cavities, a fibrous material such as cellulose insulation or glass wool is blown into the cavity through suitably drilled holes until it fills the entire wall space.
Foam can also be used for this purpose. Insulating my loft ceiling. What exactly are you trying to achieve here?
