Wraptite® Is The Solution For Dundee Young Persons’ Home The Wraptite external air barrier system from the A. Proctor Group has been chosen for its high performance airtight insulation for a new home for young people in Dundee, Scotland. The new £3m single-storey building will be a home for some of the most vulnerable young people in the city where they can grow up in a supportive and caring setting. The project design includes ensuite bedrooms, shared living space, dining, kitchen, and activities facilities, and accommodation for staff. Robertson Construction Tayside secured the project as part of a direct award through Places for People Procurement Hub Framework. The specification created by Dundee City Council Architects for the project was to use materials to achieve high value performance and help achieve good airtightness. Robertson Construction Tayside appointed Robertson Timber Engineering as the timber frame manufacturer and supplier for the project. Nicola Jackson, Net Zero Projects Lead at Robertson Group explained. “Installing the product at low level in the factory allowed the membrane to be more easily applied and avoided the risk of working at height. The factory installation also enabled the product to be installed in completely dry conditions to ensure full adhesion in a quality-controlled environment to deliver the required airtightness requirements. The product is very durable and provides excellent protection, reducing any risk of damage on site.” The Wraptite air barrier system is a safe and simplified membrane system. It provides a fully self-adhered vapour permeable air barrier certified by the BBA and combines the critical properties of vapour permeability and airtightness. www.proctorgroup.com
Mapei Protects New Homes In Historic Building Conversion A Mapei waterproofing membrane & watertight concrete system has been designed by Lainton Services, Stockport as part of a sympathetic conversion of a former medical Centre in Altrincham, Cheshire. Following relocation of the centre, the character building has been transformed into new homes. The Mapei system was installed within basement areas, by Lainton Services, with components supplied by Kestral Construction Products. The historic town-centre building is located in a conservation area, on the same site as the Grade II listed Church of St John the Evangelist which has also been converted. Dating back to the 1800’s, the building was originally used as a school, before being converted into a medical centre in the 1980’s. The sensitive £4m redevelopment provides five high-end 3 and 4 bedroom homes, with basements and private gardens. Two Mapei pre & post applied HDPE (High Density Polyethylene Geomembrane) waterproof membranes were used to protect the underground structure of the building: Mapeproof AL AP was applied before concrete was poured and Mapeproof AL 1200 AP was applied afterwards. The robust membranes are highly resistant to puncturing, tearing, natural elements and UV rays, and they provide a barrier against groundwater, soil moisture, radon and methane gas. On contact with concrete, the system forms a permanent, tough bond. The system also included Mapei’s watertight concrete admixture Idrocrete KR 1000: a powder admixture made from special hydrophilic components that reduces the permeability of hardened concrete which was supplied by Cemex – along with Mapeproof Liquid Membrane: a two-component polyurethane elastomeric, thixotropic, liquid waterproofing membrane. www.mapei.co.uk
