Spacetherm® A1 - Non-Combustible Aerogel Insulation

Ultra-Thin Thermal Insulation for Façades and Space-Critical Applications

Spacetherm A1 is a flexible, silica aerogel-based insulation material of limited combustibility used for exterior and interior applications. The product is used to optimise the thermal performance and fire properties of façade systems in a number of ways. These include enhancing the thermal performance of the ventilated façade, and addressing thermal bridging in the façade. Spacetherm A1 is also useful in minimising thermal bridges around windows in areas such as window reveals and roller shutter cases.

Engineered for space-critical applications, the product offers low thermal conductivity, plus breathability allied to hydrophobic characteristics. Spacetherm A1 can be also be supplied in a variety of finishes, the substantial layers meeting the requirements for A1 classification (insulation, MgO and plasterboard).

Product Information

Spacetherm A1 Certified to Maintain A1 Fire Classification at Thicknesses Up to 200mm

The Proctor Group has undertaken an extensive review, testing, and certification process with the United Kingdom Test Centre (UKTC) in East Kilbride. This comprehensive review covered both Spacetherm A1 insulation and its laminated variants.

The review confirmed that Spacetherm A1 Blanket and Spacetherm Multi can be supplied as bonded with up to 20 layers, providing up to 200mm of insulation thickness, while retaining their A1 reaction-to-fire classification, to BS EN 13501-1:2018. This classification provides designers and specifiers with increased confidence when selecting Spacetherm solutions and enables greater flexibility in meeting the fire performance and thermal requirements of high-rise and other relevant buildings.
