Cavity Wall Insulation Polystyrene Bead

If properly installed these materials should theoretically be superior to mineral wool fibre as they are inherently waterproof.

Cavity wall insulation polystyrene bead.

Any rainwater penetrating the outer leaf will drain harmlessly to the footings. Polystyrene beads are produced to a specified size and density which remains unaltered during the installation process. The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as. Neither material is used as widely as mineral wool fibre because of cost.

What is expanded polystyrene bead. The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue. There are two other materials commonly used for cavity wall insulation bonded polystyrene beads and foam. The use of polystyrene bead for cavity wall insulation does not prejudice the fire resistance properties of the wall.

Cavity walls over 225mm can be accommodated with the input of an engineer and are project specific. Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass. Kore fill cavity wall insulation is expanded polystyrene eps injected in bead form into a wall cavity to form an insulating mass. This method of cavity wall insulation consists of pre formed polystyrene beads which are usually combined with a binding agent or adhesive and then injected into the cavity space between the outer and inner masonary work.

This makes kore fill the perfect solution to meet nzeb part l 2019 cost effectively. The material is resistant to water penetration and will not transmit water across the cavity by capillary action or from below dpc level. The bonding agent is used to provide long term stability to the insulant. 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.

With outstanding cavity wall insulating properties it is ideal for domestic commercial and industrial use. 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. Ciga cavity insulation guarantee agency issue an independent 25 year. Thermabead cavity wall insulation are industry leaders in providing high performance injected blown bead insulation systems.
