EWI EPS Insulation Boards | Lightweight, Cost-Effective Thermal Protection for External Walls

Expanded Polystyrene (EPS) Insulation Boards provide high-performance thermal efficiency for external wall insulation (EWI) systems. Designed to enhance U-values, reduce heat loss, and prevent water penetration and condensation, EPS insulation is a versatile, durable, and budget-friendly choice for residential and commercial buildings.

Key Features of EPS Insulation:

✅ Superior Thermal Conductivity: 0.032W/(m²K) for excellent insulation performance.
✅ Lightweight Yet Durable: Easy to handle, cut, and install.
✅ Versatile Application: Compatible with timber, masonry, cavity wall insulation, and a wide range of rendering systems.
✅ Variety of Thicknesses: Available from 20mm to 100mm, sold per 0.72m² board.
✅ Cost-Effective Solution: Offers excellent value for money without compromising on quality or thermal performance.
✅ Environmentally Friendly: Lower adhesive and fixings costs due to its lightweight nature.
✅ Fire Classification: Rated Class E for fire resistance.
✅ Strong & Stable: Compressive strength of 70 kPa, bending strength of ≥ 75 kPa.

Why Choose EPS for External Wall Insulation?

• Affordable & Efficient – One of the most cost-effective insulation materials on the market.
