SPI GREY EPS BOARD

The SPI Grey EPS Board is a high‑performance expanded polystyrene (EPS) insulation board designed specifically for External Wall Insulation (EWI) systems: and thermal upgrading of buildings. EPS insulation boards provide excellent thermal performance that helps improve U‑values, reduce heat loss, and enhance energy efficiency in both residential and commercial external wall applications.

These lightweight, durable insulation panels are compatible with a wide range of substrates - including masonry, timber backing and system‑built walls - and can be fixed using adhesive and mechanical fixings as part of a full EWI build‑up. Once installed, EPS boards offer a stable, flat substrate ready for basecoats, reinforcement mesh and decorative render finishes.

Key Features & Benefits
- High‑quality expanded polystyrene (EPS) insulation board for external wall insulation.
- Improves thermal performance and reduces energy loss by enhancing U‑values.
- Lightweight and easy to handle, cut and install.
- Durable and long‑lasting thermal insulation solution.
- Compatible with most EWI adhesives and render systems.
- Available in a variety of thicknesses to suit project insulation requirements.
- Supplied in boards sized 1200mm x 600mm, covering 0.72 m� per board.

Applications
The SPI Grey EPS Board is widely used as the insulation layer in external wall insulation (EWI) - both in new build and retrofit projects - working with basecoats and decorative render finishes to provide a continuous insulation envelope that reduces thermal bridging and weather‑related issues.

EPS insulation boards are also suitable for:
- Timber and masonry wall substrates
- Cavity wall insulation applications
- Render system build‑ups as part of energy‑saving projects
- Enhancing comfort and reducing heating costs across residential and commercial buildings
