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.

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 bonding agent is used to provide long term stability to the insulant. If the puffed beads fill the cavity the space can obtain r values close to that of fiberglass insulation.

But there are other options. 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. 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.

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. 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.

Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass. Another application in construction for polystyrene beads is retrofit insulation of un insulated exterior walls. Independent research has confirmed that cavity wall insulation is a very reliable process. 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.

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.
