If you're improving the thermal performance of a building, Jablite 70HPE+ offers a reliable, energy-efficient solution. These external wall insulation boards are made from expanded polystyrene (EPS) and are designed to be either bonded or mechanically fixed to the exterior of your building.
Each board measures 1200mm x 600mm and covers 0.72m². Available in a wide range of thicknesses—from 20mm up to 150mm—they provide flexibility for different insulation needs while maintaining thermal conductivity as low as 0.030 W/mK.
Built for Versatile Applications
Jablite 70HPE+ insulation boards are designed to work with a variety of external finishes. Whether you're using timber or plastic weatherboarding, tile hanging, or reinforced render systems, these boards are fully compatible. They're ideal for residential or commercial EWI (External Wall Insulation) projects aiming to improve energy performance and reduce heat loss.
Durable and Easy to Work With
These boards are lightweight, flood-proof, and rot-resistant, meaning they’ll remain effective for the lifetime of the building when installed correctly. They're easy to cut with a sharp knife, allowing for quick and precise fitting—even around awkward shapes or architectural details.
