Cavity Wall Insulation Polystyrene Bead

The material is resistant to water penetration and will not transmit water across the cavity by capillary action or from below dpc level.

Cavity wall insulation polystyrene bead.

The main materials used by nia installers are mineral wool glass or rock wool eps bead polystyrene bead and pu foam polyurethane foam cavity wall insulation can lower your heating bills lower wear and tear on your boiler and reduce global warming and climate change. There are two other materials commonly used for cavity wall insulation bonded polystyrene beads and foam. Neither material is used as widely as mineral wool fibre because of cost. The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue.

Cavity walls over 225mm can be accommodated with the input of an engineer and are project specific. If properly installed these materials should theoretically be superior to mineral wool fibre as they are inherently waterproof. This makes kore fill the perfect solution to meet nzeb part l 2019 cost effectively. For the safety of our customers our standard bead polystyrene cavity wall insulation is manufactured with a flame retardant additive and tested to bs476 part 12.

Any rainwater penetrating the outer leaf will drain harmlessly to the footings. Kore fill cavity wall insulation is expanded polystyrene eps injected in bead form into a wall cavity to form an insulating mass. The bonded bead significantly reduces thermal transmittance across the cavity. Providing 100 cavity fill with no cold spots no waste and easy to install.

1991 approx bead size inches mm. The use of polystyrene bead for cavity wall insulation does not prejudice the fire resistance properties of the wall. The thermo efficient qualities of custompac polystyrene bead make it a versatile wall cavity insulation material. The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as.

With outstanding cavity wall insulating properties it is ideal for domestic commercial and industrial use. Thermabead cavity wall insulation are industry leaders in providing high performance injected blown bead insulation systems. The bonding agent is used to provide long term stability to the insulant. 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.
