Kingspan Thermawall TW50 Cavity Wall Insulation 450mm x 1200mm
Kingspan Thermawall TW50 Cavity Wall Insulation is a high-performance, rigid insulation board designed for use in partial fill cavity wall constructions. Manufactured from premium PIR (polyisocyanurate) foam with low thermal conductivity, it delivers outstanding energy efficiency and helps meet modern Building Regulation requirements with minimal wall thickness.
Each board measures 450mm x 1200mm and features a low emissivity foil facing on both sides, enhancing thermal performance by reflecting radiant heat. The boards are lightweight, easy to handle, and simple to cut to size — making installation quick and precise.
Ideal for both new builds and refurbishments, Kingspan TW50 provides long-term thermal stability, excellent moisture resistance, and contributes to lower energy bills and improved comfort throughout the property.
Key Features & Benefits
• Premium PIR insulation for superior thermal performance
• Foil facings enhance heat reflection and energy efficiency
• Lightweight boards — easy to handle, cut, and install
• Resistant to moisture and water vapour ingress
• Suitable for new build and retrofit cavity wall applications
• Reduces heat loss and helps achieve Part L compliance
• Board size: 450mm x 1200mm
