Wraptite-SA airtight membrane has been specified to achieve a highly efficient building fabric as part of a concept to create a terrace of 5 Zero Carbon homes in a site close to the historic Hastings Castle. The design, by award winning eco-architects ZED factory, and their partner the Zero Bills Home Company, has transformed a derelict site into a modern development combining high quality with highly efficient homes, during the year, which coincides with the 950th anniversary of the famous 1066 battle.
The homes are built from pre-fabricated heavy weight timber frame panels, with Wraptite-SA, self-adhering vapour permeable air barrier being applied on site. The use of Wraptite-SA makes a significant contribution to a building’s thermal performance by preventing lateral air movement. It also provides high vapour permeability in a continuously sealed, self-adhered, airtight membrane.
Another key factor in the selection of materials was the requirement to meet the durability of being located in a marine environment. Wraptite- SA’s high vapour permeability allows damp sheathing to dry quickly and moisture vapour to escape. This ensures good indoor air quality and reduces the likelihood of mould, mildew, condensation, timber distortion and metal corrosion.
Wraptite-SA was applied externally, quickly and easily to the timber panels in continuous pieces, unlike internal air barriers, which can be more complex and costly to install due to the need to accommodate building services such as electrical, lighting, heating and drainage systems.
In the battle for airtightness Wraptite continues to reassure, in both in performance, and in ease of application. The only self-adhering vapour permeable air barrier certifi ed by the BBA, in both wall and pitched roof applications, Wraptite-SA continues to be the preferred choice in the drive towards Zero Carbon homes.
