HAUS - net-zero Wall U-Value 0.12 (W/m2k)
The HAUS net-zero Wall is a high-performance closed-panel timber system engineered for energy-efficient, sustainable construction. With a total thickness of 412.2 mm, it achieves a U-value of 0.12 W/m²K, sound reduction over 48 dB, and fire resistance rated REI 60, upgradeable to REI 90. The wall features a multi-layered build including gypsum fibre board, mineral wool insulation, vapour barriers, wood-based panels, and ventilated timber battens. External finishes are fully customisable, with options such as brick-slip, render, timber, stone, or metal cladding. Designed to meet the highest standards in thermal, acoustic, and fire performance for modern construction.
Pitched Roof HAUS Passiv U-Value 0.11 (W/m²K)
The HAUS Passiv Pitched Roof is a highly insulated prefabricated roofing system engineered for superior energy performance. With a construction thickness of 492.9 mm (excluding the roof covering), it achieves an excellent U-value of 0.11 W/m²K and a sound reduction of over 51 dB. The multi-layered structure integrates mineral wool insulation, a vapour barrier, flexible waterproofing membranes, and robust timber construction for outstanding airtightness and thermal stability. Fire resistance is REI 30, upgradeable to REI 60. The system supports a range of roof finishes—traditional clay, fibre cement, zinc, slate, or solar PV—delivering both performance and architectural flexibility. Ideal for sustainable pitched or sloped roof applications.
Triple Glazed Windows
