The ambitious target of zero carbon homes from 2016 means the way we design and build new homes is changing, with higher levels of insulation and a greater focus on the air tightness of the building envelope. This forward thinking development has been designed to test proposed specifications for each regulatory stage along the way.
Two plots were designed to meet the current requirements under the 2010 revisions to Approved Document Part L. Two further plots were constructed to meet the Fabric Energy Efficiency Standard (FEES) and the final plot was built to meet the expected Zero Carbon Hub Carbon Compliance Standard.
Knauf Insulation supplied its Supafil 34 for use across the external walls of the development and Supafil Party Wall for the adjoining party walls. Offering an unrivalled 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.
Paul Beardsley from Mark Group said, “Using Supafil 34 and Supafil Party Wall for the external and party walls of the development means that all cavity walls can be insulated using the same machinery - saving time and labour, as well as hidden onsite costs for the house builder, such as storage and purchasing of materials up front.”
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.
