180mm Stylite Plustherm Grey EPS 70 Board

180mm Expanded polystyrene (EPS) insulation board delivers outstanding thermal performance for external wall insulation systems. This robust material significantly improves building thermal efficiency, enhances U-values, and minimises water ingress and condensation risks. The 180mm boards work seamlessly with timber, masonry, system-built properties, tile hanging, and numerous rendering systems. Installation involves adhesive and mechanical fixings applied to masonry or timber-backed walls, with cavity void installation also available for cavity wall insulation applications.

180mm Stylite Plustherm Grey EPS 70 Insulation Board stands out as the preferred choice for external wall insulation systems, delivering exceptional performance at competitive pricing. Selecting this cost-effective 180mm EPS board enables budget-conscious projects to maintain quality and thermal performance standards.

Installation of 180mm EPS within an EWI system benefits from lower material costs. The material's lightweight nature requires minimal-strength adhesive and plastic fixings rather than metal alternatives. Since 180mm Stylite EPS is non-breathable, it accommodates economical thin coat renders including EWI-075 Silicone Render or EWI-040 Acrylic Render.

Typical Applications

180mm Stylite Expanded Polystyrene insulation boards provide an excellent solution for external wall insulation projects. These boards attach readily to existing wall substrates, delivering immediate improvements to both aesthetic appeal and thermal performance. Applying insulation to the external wall surface rather than internally reduces interstitial condensation formation within the wall structure.

Stylite 180mm External Wall Insulation board accommodates diverse wall constructions, including solid brick and timber frame walls. External wall insulation typically receives a rendered protective finish, with application methods varying by system type. Furthermore, 180mm Stylite EWI boards suit rail or drained cavity EWI system installations.

Preparation

Deploy netting on scaffolding to prevent polystyrene debris dispersal in windy conditions. We strongly advise using hot knife or hot wire cutters to minimise polystyrene offcuts; standard knives work if necessary. Ideally, cut 180mm EPS insulation boards in sheltered areas to prevent offcuts scattering.

EPS Insulation Application

Always follow the manufacturer's installation guidelines when fitting EPS insulation boards, ensuring comprehensive design and application coverage. Begin by securing EPS boards to the substrate (masonry or timber) using mortar/adhesive or mechanical fixings.

Following external wall installation, protect boards with an outer layer such as mortar basecoat or netting, shielding from excessive heat, moisture, and UV damage.

Before applying basecoat or mortar with fibreglass mesh, rasp or sand the board surface to create texture for better adhesion. Once complete, the substrate accepts fibreglass mesh application. Consult the full installation guide for comprehensive instructions.

EPS Insulation Storage

Review the manufacturer's expiry date for shelf life information. Store in dry conditions within original packaging. Prevent exposure to extreme heat or direct sunlight.
