Polystyrene Bead Cavity Wall Insulation Material

The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue.

Polystyrene bead cavity wall insulation material.

Types of cavity wall insulation the most common type of material used in ireland is a type of polystyrene bead system. 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 bonding agent is used to provide long term stability to the insulant. Polystyrene beads are produced to a specified size and density which remains unaltered during the.

Polystyrene bead is a system of insulating cavity walls with flame retardant adhesive coated polystyrene beads. Problems are therefore extremely rare but if they do occur ciga has the expertise to ensure that they are swiftly rectified. 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. 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. Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass. 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. 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. The bonded bead significantly reduces thermal transmittance across the cavity. 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. 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.
