Polystyrene Bead Cavity Wall Insulation Material

The thermo efficient qualities of custompac polystyrene bead make it a versatile wall cavity insulation material.

Polystyrene bead cavity wall insulation material.

The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as. Polystyrene beads are produced to a specified size and density which remains unaltered during the. 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. 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. 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. 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. Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass.

Independent research has confirmed that cavity wall insulation is a very reliable process. 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. 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. If the puffed beads fill the cavity the space can obtain r values close to that of fiberglass insulation.

Types of cavity wall insulation the most common type of material used in ireland is a type of polystyrene bead system. 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. Another application in construction for polystyrene beads is retrofit insulation of un insulated exterior walls. But there are other options.

The bonded bead significantly reduces thermal transmittance across the cavity.
