EPS Insulation

Expanded polystyrene EPS insulation board is high-performing thermal insulation at the centre of our external wall insulation systems. It upgrades the thermal properties of a building, improving U-values, reducing the risk of water penetration and condensation. EPS boards can be used on timber, masonry and system-built properties as well as for tile hanging and a wide range of rendering systems. It is designed to be applied externally to masonry or timber-backed walls using adhesive and mechanical fixings. EPS boards can also be installed in the cavity void, if the property is being insulated using cavity wall insulation.

  • Great value
  • Easy to work with
  • Lightweight but durable
  • Dense material – low thermal conductivity
  • Low moisture absorption
  • Non-degrading
  • Available in 10mm increments

Preparation

Use netting on scaffolding to reduce the amount of polystyrene blowing about in the wind.

Try to use a hot knife or hot wire cutters to minimise the number of polystyrene offcuts, although a standard saw can be used – ideally, cut the EPS insulation boards within a covered area to reduce offcuts blowing around.

Application

EPS insulation boards should be installed in accordance with the manufacturer’s installation guidelines – these should cover design and all aspects of the application of the insulation. The boards are initially fixed to the substrate (masonry or timber) either by a mortar/adhesive or simply by mechanical fixings.

After having been fixed to an external wall, the EPS insulation boards should be covered with an outer layer, either by the mortar basecoat or simply by a netting covering to protect from excessive heat, moisture and UV exposure.

Before applying the basecoat or mortar for the fibreglass mesh, the top surface of the EPS insulation board needs to be rasped or sanded down to produce an abrasive surface. Once this has been done, the substrate is ready for the application of the fibreglass mesh.
