Miller Homes has specified Knauf Insulation’s Supafil glass mineral wool and Earthwool® loft roll products for an innovative development at Dukesmead in Bingham, Nottingham.
The development includes five ‘Fabric First’ homes, built to meet current and future energy efficiency standards.
Two plots have been designed to meet the requirements of Approved Document Part L. Two further plots have been constructed to meet the Fabric Energy Efficiency Standard (FEES) and the final plot has been built to meet the expected Zero Carbon Hub Carbon Compliance Standard.
The exterior walls to the dwellings have been constructed using a conventional, super-insulated masonry system, incorporating Knauf Insulation’s Supafil blown-in glass mineral wool insulation. The roof constructions are a timber, pitched rafter design and the ground floors consist of an insulated beam and block system.
Knauf Insulation’s Supafil 34 was specified for use across the external walls of the development and Supafil Party Wall for the adjoining party walls. Offering a combination of thermal performance and on-site practicality, Supafil 34 is a high quality blown-in mineral wool with a thermal conductivity value of just 0.034W/mK. Not only is this the lowest thermal conductivity value of any blown-in mineral wool product in the UK1, it is also the UK’s first blown insulation product to meet the new Lambda 90/90 requirement of European Standard BS EN 14064:1:2010.
Knauf Insulation’s Earthwool Loft Roll was also specified throughout the properties, offering a lightweight, non–combustible glass mineral wool solution, which was installed between the timber joists to deliver outstanding thermal and fire performance.
Knauf Insulation’s Earthwool products are all manufactured using the revolutionary ECOSE® Technology – a formaldehyde-free binder based on rapidly renewable materials instead of petro-based chemicals. ECOSE Technology is also up to 70 per cent less energy intensive than traditional binders – enhancing the environmental credentials of Knauf Insulation’s Earthwool products without affecting the thermal, acoustic or fire performance.
