Stylite Plustherm Grey EPS 70 100mm Board

100mm Expanded polystyrene (EPS) insulation board delivers outstanding thermal performance for external wall insulation systems. This robust material substantially improves building thermal efficiency, enhancing U-values whilst reducing water ingress and condensation risks. The 100mm thickness works seamlessly with timber, masonry, system-built properties, tile hanging, and various rendering finishes. Installation involves adhesive and mechanical fixings applied to masonry or timber-backed walls, with optional cavity void placement for cavity wall insulation applications.

100mm Stylite Plustherm Grey EPS 70 represents the preferred choice for external wall insulation systems, combining exceptional thermal performance with outstanding value. Selecting this cost-effective 100mm EPS board delivers significant savings without sacrificing quality or thermal capability.

Installation of 100mm EPS within an EWI system benefits from economical materials and straightforward application. The lightweight nature of EPS permits lower-strength adhesive and plastic fixings rather than metal alternatives. Being non-breathable, 100mm Stylite EPS enables the use of budget-friendly thin coat renders, including EWI-075 Silicone Render or EWI-040 Acrylic Render.

Typical Applications

100mm 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 minimises the risk of interstitial condensation developing within wall cavities.

Stylite 100mm External Wall Insulation board accommodates diverse wall constructions, from solid brickwork to timber frame walls. External wall insulation typically receives a rendered protective coating, with application methods varying by system specification. Furthermore, 100mm Stylite EWI boards suit rail or drained cavity EWI system installations.

Preparation

Deploy netting on scaffolding to prevent polystyrene dispersal during windy conditions. We strongly advise using hot knife or hot wire cutters to minimise polystyrene waste generation, though standard knives remain viable if necessary. Ideally, perform cutting of 100mm EPS insulation boards within covered spaces to prevent offcuts from becoming airborne.

EPS Insulation Application

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

Following external wall attachment, apply a protective outer layer such as mortar basecoat or netting to shield against excessive heat, moisture, and UV damage.

Before applying basecoat or mortar with fibreglass mesh, rasp or sand the board surface to establish proper adhesion. Once prepared, the substrate accepts fibreglass mesh application. Consult the full 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.
