Wraptite - Eco House

An impressive new contemporary award-winning Eco House in Perthshire is set to benefit from the superior airtightness performance qualities of Wraptite from the A. Proctor Group.

The house “Tighétébhu” was constructed by SIPS Scotland and has been chosen as the winner of the Best SIPs Home in the Build It Awards 2018. The new property is a self-build project commissioned by Keira Proctor, Managing Director of the A. Proctor Group, and designed by Allan Corfield Architects, Dunfermline who are specialists in Self Build. Commenting on the news about the award Keira said, “I am delighted that Tighétébhu has been recognised for the award as ‘Best SIPs Home’, which is testimony to the high quality of the work achieved by SIPs Scotland, and it’s a further endorsement of the superior airtight performance of Wraptite in buildings.”

Wraptite, the only self-adhering external vapour permeable air barrier certified by the BBA, was installed as part of the Structural Insulated Panel (SIPs) construction of the home. The use of Wraptite in the construction 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.

Unlike internal air barriers, which can be complex and costly to install due to the need to accommodate building services such as electrical, lighting, heating and drainage systems, positioning a highly breathable, yet airtight barrier on the outside of the structural frame simplifies the process of maintaining the envelope’s integrity, as there are less building services and structural penetrations to be sealed.

Another key benefit of the system is that the high vapour permeability of Wraptite allows the substrate beneath 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.

The self-adhesive nature of Wraptite means that it is easy to apply together with Wraptite corner detailing and there are no requirements for mechanical fixings. During the construction, the membrane was wrapped externally around the whole house, which proved invaluable in protecting the building from the elements throughout the length of the project and it also kept internal finishings safe from the elements, and the site workers warm!

Alongside Wraptite, additional products were selected from the A.Proctor portfolio to enhance the thermal performance of the property including Reflectatherm Premier a high performance reflective, vapour control layer, and Spacetherm CBS (Cold Bridge Strip), which uses Spacetherm Aerogel
