Polystyrene Bead Cavity Wall Insulation Material

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.

Polystyrene bead cavity wall insulation material.

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. Another application in construction for polystyrene beads is retrofit insulation of un insulated exterior walls. In this application the puffed beads are poured into the wall cavity between the studs by drilling a hole in the top of the wall. Polystyrene bead is a system of insulating cavity walls with flame retardant adhesive coated polystyrene beads.

Polystyrene beads are produced to a specified size and density which remains unaltered during the. For the safety of our customers our standard bead polystyrene cavity wall insulation is manufactured with a flame retardant additive and tested to bs 5852. 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. But there are other options.

We use graphite 27 plus cavity wall insulation beads which consists of an expanded polystyrene material in bead form which is injected into the wall along with a bonding agent. If the puffed beads fill the cavity the space can obtain r values close to that of fiberglass insulation. The thermo efficient qualities of custompac polystyrene bead make it a versatile wall cavity insulation material. Types of cavity wall insulation the most common type of material used in ireland is a type of polystyrene bead system.

The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue. The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as. The polystyrene used for cwi is in the form of virgin pre formed bead which is usually combined with a binding agent or adhesive at the time of injection. The bonded bead significantly reduces thermal transmittance across the cavity.

Problems are therefore extremely rare but if they do occur ciga has the expertise to ensure that they are swiftly rectified.
