Types of cavity wall insulation the most common type of material used in ireland is a type of polystyrene bead system.
Polypearl is injected as individual eps insulation beads which then form a consistent matrix inside the cavity using an adhesive to hold them in place.
The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue.
The unique free flowing insulation beads set with point to point adhesion allowing tiny air pockets which allow the cavity to breathe and moisture to drain away.
The bonded bead significantly reduces thermal transmittance across the cavity.
Another application in construction for polystyrene beads is retrofit insulation of un insulated exterior walls.
Cavity walls are usually built of brick and consist of two thin walls separated by a gap or cavity with metal wall ties holding them together.
If the puffed beads fill the cavity the space can obtain r values close to that of fiberglass insulation.
