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.

Polystyrene bead cavity wall insulation material.

Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass. 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. 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. The bonded bead significantly reduces thermal transmittance across the cavity.

The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as. Independent research has confirmed that cavity wall insulation is a very reliable process. 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. If the puffed beads fill the cavity the space can obtain r values close to that of fiberglass insulation.

But there are other options. Polystyrene bead is a system of insulating cavity walls with flame retardant adhesive coated polystyrene beads. The bonding agent is used to provide long term stability to the insulant. 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 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. Polystyrene beads are produced to a specified size and density which remains unaltered during the. The thermo efficient qualities of custompac polystyrene bead make it a versatile wall cavity insulation material. Another application in construction for polystyrene beads is retrofit insulation of un insulated exterior walls.

Types of cavity wall insulation the most common type of material used in ireland is a type of polystyrene bead system.
