130mm Stylite Plustherm Grey EPS 70 Board

130mm Expanded polystyrene (EPS) insulation boards deliver outstanding thermal performance for external wall insulation systems. These high-quality boards substantially improve building thermal efficiency, enhance U-values, and minimise water ingress and condensation risks. The 130mm thickness works effectively with timber, masonry, system-built properties, tile hanging, and numerous rendering finishes. Installation involves adhesive and mechanical fixings applied to masonry or timber-backed walls, with cavity void installation also available for cavity wall insulation applications.

130mm Stylite Plustherm Grey EPS 70 Insulation Board remains the preferred choice for external wall insulation systems, offering exceptional performance at competitive pricing. Selecting this cost-effective 130mm EPS board delivers significant savings whilst maintaining superior quality and thermal performance standards.

For EWI system installation, 130mm Stylite EPS boards reduce material expenses considerably. The lightweight nature requires lower-strength adhesive and plastic fixings rather than metal alternatives. Being non-breathable, this product permits economical thin coat renders, including EWI-075 Silicone Render or EWI-040 Acrylic Render.

Typical Applications

130mm Stylite Expanded Polystyrene insulation boards provide an excellent solution for external wall insulation projects. These boards attach securely to existing wall substrates, immediately enhancing both aesthetic appeal and thermal performance. Applying insulation to the external wall surface rather than internally significantly reduces interstitial condensation formation within the wall structure.

Stylite 130mm External Wall Insulation board suits diverse wall constructions, from solid brickwork to timber frame walls. External wall insulation typically receives a rendered protective finish, with application methods varying by system type. Furthermore, 130mm Stylite EWI boards integrate seamlessly into rail or drained cavity EWI systems.

Preparation

Deploy netting on scaffolding to prevent polystyrene debris dispersal during windy conditions. We strongly recommend hot knife or hot wire cutters to minimise offcuts, though standard knives remain viable alternatives. Ideally, perform cutting in sheltered areas to avoid polystyrene fragments scattering.

EPS Insulation Application

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

After securing boards to external walls, apply a protective outer layer such as a mortar basecoat or netting to shield against excessive heat, moisture, and UV damage.

Prior to basecoat or mortar application for fibreglass mesh, rasp or sand the board surface to establish proper adhesion. Once prepared, the substrate accepts fibreglass mesh application. Consult the complete installation guide for comprehensive instructions.

EPS Insulation Storage

Verify the manufacturer's expiry date for shelf life information. Store in dry conditions within original packaging. Protect from excessive heat and direct UV exposure.
