SANDSTONE Energy Saving Thermal Ceramic Foam Insulation Board for Exterior Wall Panel

Energy codes increasingly set a wall U value that a decorative finish alone cannot reach. This sandstone thermal insulation board meets the requirement with a 50mm inorganic ceramic core and a conductivity of 0.067 W/(m·K), giving a thermal resistance of about 0.75 m²·K/W per board.

Because the same board carries the sandstone finish, the insulation layer, the weather barrier and the decoration are installed in a single operation. Consultants can drop a separate render system, and contractors lose one trade from the facade programme without losing the sandstone appearance.

• 50mm core delivers a lower wall U value
• Low thermal conductivity inorganic ceramic structure
• Class A1 non-combustible with no flame spread
• Large 1000 x 500mm board speeds up fixing on site
• Water absorption of 0.6% keeps insulation performance stable
• Sandstone decorative face removes the need for render

• Energy efficient exterior wall insulation
• Green building and low carbon projects
• Industrial and commercial facades
• Compliance work against local energy codes

Insulation performance depends on continuity. The 1000 x 500 x 50mm sandstone thermal insulation board is installed with tightly butted joints, staggered courses and full adhesive coverage to avoid thermal bridging. Around openings, boards are cut to fit and sealed at the reveal, so the calculated U value is achieved on site rather than only on paper. Services penetrating the wall are sleeved and sealed with compatible mastic.

Insulation boards ship on timber pallets, banded and wrapped against moisture. Pallets are marked with thickness and thermal data, allowing the site team to verify the delivered build-up against the energy calculation before installation begins.
