Our platinum grey expanded polystyrene EPS insulation board is a premium product to use for application of EWI to your external walls. The boards are cut into various thicknesses (20mm, 50mm, 70mm and 100mm) depending on your requirements. Typical product features:

  • Insulating material that will last a lifetime
  • East to work with
  • Lightweight but durable
  • Dense material – low thermal conductivity
  • Bonded to substrate by adhesion and mechanical fixings
  • Low moisture absorption

This expanded polystyrene (EPS) board is the insulating material component of the external wall insulation system. It upgrades the thermal properties of a building, improving U-values, reducing the risk of water penetration and condensation. The material can also be used on existing or new build properties.

The material is made out of polystyrene and comes in platinum grey ready to be applied over a dry substrate or adhesion-backed mortar. These EPS boards can be used on timber, masonry and system build properties as well as for tile hanging and a wide range of rendering systems.

Intended Uses:

The product is designed to be applied externally to masonry or timber-backed walls, either by mechanical fixing with supplementary adhesive or just by mechanical fixings. The EPS platinum grey boards can also be installed in the cavity void, if the property is being insulated using cavity wall insulation.

Technical Specifications:

Composition: expanded polysterene, graphite

Thermal Conductivity: 0.032W/(m2K)

Reaction to Fire: Class E

Size of boards: 1000mm by 500mm

Thickness available: 20mm, 50mm, 70mm, 100mm

Coverage in pack: 1m2

Bending strength: >= 75kPa

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 amount of polystyrene offcuts, although a standard saw can be used – ideally, cut the 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 boards should be covered with an outer layer, either by the mortar basecoat or simply by a netting covering to protect from exsessive heat, moisture and UV exposure.

Before applying the basecoat or mortar for the fibre glass mesh, the top surface of the EPS 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 fibre glass mesh.

Clean-up:

Use an industrial hoover to clean-up the polystyrene bits.

Packaging:

Stacked by stacking boards – coverage depends on board thickness

100mm board – coverage 1m2

Storage:

Shelf life: please see the manufacturer’s date of expiry. Keep in a dry place, in the original packaging. Avoid excess heat or UV light exposure.

Safety Measures:

Wear eye protection, gloves and a mask. Take extra caution when using cutting equipment.
