25mm Kingspan AlphaCore Pure – Silica‑Based Insulation Board - 600mm x 1000mm

25mm Kingspan AlphaCore Pure is a high‑performance, pure silica‑based insulation board designed for modern façade and wall systems where ultra‑thin build‑ups and enhanced fire performance are required. Its microporous silica core delivers excellent thermal efficiency with a declared thermal conductivity of 0.020 W/mK, making it ideal for space‑restricted applications in both new‑build and refurbishment projects.

AlphaCore provides a stable, inorganic insulation solution with high compressive strength, excellent moisture resistance, and reliable long‑term performance. It is suitable for rainscreen façades, steel‑frame and timber‑frame walls, and internal lining upgrades.
