The polystyrene bead can be injected into spaces other insulation materials might not be suitable for such as.
Cavity wall insulation polystyrene bead.
Any rainwater penetrating the outer leaf will drain harmlessly to the footings.
Platinum silver bead cavity wall insulation is expanded polystyrene eps injected in bead form into a cavity to form an insulating mass.
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.
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.
The bonded bead significantly reduces thermal transmittance across the cavity.
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 installation process.
What is expanded polystyrene bead.
Providing 100 cavity fill with no cold spots no waste and easy to install.
The material is resistant to water penetration and will not transmit water across the cavity by capillary action or from below dpc level.
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.
If properly installed these materials should theoretically be superior to mineral wool fibre as they are inherently waterproof.
Neither material is used as widely as mineral wool fibre because of cost.
There are two other materials commonly used for cavity wall insulation bonded polystyrene beads and foam.
Kore fill cavity wall insulation is expanded polystyrene eps injected in bead form into a wall cavity to form an insulating mass.
With outstanding cavity wall insulating properties it is ideal for domestic commercial and industrial use.
Ciga cavity insulation guarantee agency issue an independent 25 year.
The cavity wall insulation solidifies in the cavity as it is injected along with a special bonding agent adhesive glue.
This makes kore fill the perfect solution to meet nzeb part l 2019 cost effectively.
