190mm Expanded polystyrene (EPS) insulation boards deliver exceptional 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 190mm 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 additional suitability for cavity wall insulation within cavity voids.
190mm Stylite Plustherm Grey EPS 70 represents the preferred choice for external wall insulation systems, combining outstanding thermal performance with excellent value. Selecting this cost-effective 190mm EPS board delivers significant savings whilst maintaining superior quality and thermal properties.
Installation of 190mm EPS within an EWI system benefits from reduced material costs. The lightweight nature of EPS permits lower-strength adhesives and plastic fixings rather than metal alternatives. As a non-breathable material, 190mm Stylite EPS enables the application of budget-friendly thin coat renders, including EWI-075 Silicone Render or EWI-040 Acrylic Render.
190mm Stylite Expanded Polystyrene insulation boards provide an excellent solution for external wall insulation applications. These boards attach securely to existing wall substrates, delivering immediate improvements to both aesthetic appeal and thermal performance. Installing insulation on the external wall surface rather than internally significantly reduces the likelihood of interstitial condensation developing within wall cavities.
Stylite 190mm External Wall Insulation board accommodates diverse wall constructions, from solid brick to timber frame walls. External wall insulation typically receives a rendered protective coating, with application methods varying by system type. Furthermore, 190mm Stylite EWI boards suit rail and drained cavity EWI system configurations.
Deploy netting across scaffolding to prevent polystyrene debris dispersal during windy conditions. A hot knife or hot wire cutter significantly reduces polystyrene offcuts; standard knives work as alternatives. Perform cutting within covered spaces whenever feasible to minimise waste scattering.
Install EPS insulation boards strictly following manufacturer guidelines covering all design and installation specifications. Initially secure EPS boards to substrates (masonry or timber) using mortar, adhesive, or mechanical fixings.
Following substrate attachment to external walls, 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 adequate adhesion. Once prepared, the substrate accepts fibreglass mesh application. Consult the complete installation guide for comprehensive instructions.
Verify manufacturer expiry dates for shelf life information. Store in original packaging within dry conditions. Protect from intense heat or direct UV exposure.
