UK: Knauf Insulation has developed a new robust detail for aircrete blocks, which has been included within the latest edition of the Robust Detail handbook. The new detail E-WM-30 comprises two leaves of 100mm aircrete blocks, with a 100mm cavity that has been fully filled with the blown mineral wool insulation Supafil Party Wall. It is the first Robust Detail for aircrete blocks, with a blown retrofit solution that negates the need for a wet parge coat. Only a plasterboard lining is required. The detail will also achieve three points in the Health and Wellbeing section of Code for Sustainable Homes assessments.
“We are always striving to develop cost-effective solutions for our customers to make their life easier and this new robust detail is no different. We have developed this detail without a parge coat to deliver greater process efficiencies, and it offers high levels of acoustic and thermal performance, which can satisfy the requirements of the building regulations for a zero U-value party wall,” said Stephen Wise, Glass Product Manager at Knauf Insulation.
Aircrete is a lightweight aerated concrete material that provides thermal performance and is primarily used for the inner skin of external walls. The Robust Details scheme is the alternative to pre-completion sound testing for satisfying Part E of the Building Regulations in the UK.
