200mm Stylite Plustherm Grey EPS 70 Board

200mm Expanded polystyrene (EPS) insulation boards deliver exceptional thermal performance for external wall insulation systems, substantially improving building energy efficiency and reducing thermal bridging whilst minimising moisture ingress and condensation risks. These 200mm boards work seamlessly with timber, masonry, system-built properties, tile hanging, and numerous rendering finishes. Installation involves fixing to masonry or timber-backed walls using adhesive and mechanical fixings, with cavity wall applications also supported.

The 200mm Stylite Plustherm Grey EPS 70 represents the leading choice for external wall insulation systems, combining outstanding thermal performance with exceptional value. Selecting this cost-effective 200mm EPS board delivers significant savings whilst maintaining superior quality and thermal characteristics.

Installation of 200mm EPS within an EWI system proves economical, as the material's lightweight nature requires lower-strength adhesives and plastic fixings rather than metal alternatives. Being non-breathable, 200mm Stylite EPS permits application of budget-friendly thin coat renders such as EWI-075 Silicone Render or EWI-040 Acrylic Render.

Typical Applications

200mm Stylite Expanded Polystyrene insulation boards provide an excellent solution for external wall thermal enhancement. These boards attach securely to existing wall substrates, immediately upgrading both aesthetic appeal and thermal performance. Applying insulation to the external wall surface rather than internally significantly reduces the likelihood of interstitial condensation developing within the wall structure.

Stylite 200mm External Wall Insulation boards integrate effectively with diverse wall types, from solid brick construction to timber frame walls. External wall insulation typically requires a rendered protective layer, with application methods varying by system specification. Furthermore, 200mm Stylite EWI boards perform well in rail or drained cavity EWI configurations.

Preparation

Deploy netting on scaffolding to prevent polystyrene debris dispersal during windy conditions. We strongly advise using hot knife or hot wire cutting equipment to minimise polystyrene waste generation, though standard cutting tools remain viable if necessary. Where possible, perform cutting operations in sheltered areas to prevent offcuts from becoming airborne.

EPS Insulation Application

Install EPS insulation boards strictly in accordance with manufacturer specifications, addressing all installation and design considerations. Begin by securing EPS boards to the substrate (masonry or timber) via mortar/adhesive or mechanical fixings.

Following substrate attachment to external walls, protect the boards with a protective layer such as mortar basecoat or netting, shielding from excessive heat, moisture, and UV radiation.

Prior to basecoat or fibreglass mesh application, roughen the board surface through rasping or sanding to establish adequate adhesion. Once complete, the surface is prepared for fibreglass mesh installation. Consult the comprehensive installation guide for detailed procedures.

EPS Insulation Storage

Verify the manufacturer's expiry date for product shelf life. Maintain storage in dry conditions within original packaging. Protect from intense heat and direct sunlight exposure.
