Cavity Wall Insulation Polystyrene Bead

The bonding agent is used to provide long term stability to the insulant.

Cavity wall insulation polystyrene bead.

Kore fill cavity wall insulation is expanded polystyrene eps injected in bead form into a wall cavity to form an insulating mass. Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass. 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 material is resistant to water penetration and will not transmit water across the cavity by capillary action or from below dpc level. Thermabead cavity wall insulation are industry leaders in providing high performance injected blown bead insulation systems. If properly installed these materials should theoretically be superior to mineral wool fibre as they are inherently waterproof. The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as.

This makes kore fill the perfect solution to meet nzeb part l 2019 cost effectively. Providing 100 cavity fill with no cold spots no waste and easy to install. 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. The use of polystyrene bead for cavity wall insulation does not prejudice the fire resistance properties of the wall.

The bonded bead significantly reduces thermal transmittance across the cavity. 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. Cavity walls over 225mm can be accommodated with the input of an engineer and are project specific. Neither material is used as widely as mineral wool fibre because of cost.

With outstanding cavity wall insulating properties it is ideal for domestic commercial and industrial use. Polystyrene beads are produced to a specified size and density which remains unaltered during the installation process. Ciga cavity insulation guarantee agency issue an independent 25 year.
