Project architect Andrew Tate of Bowman Riley Architects, Leeds required a high-quality air tightness membrane and chose Wraptite as an external air barrier as opposed to an internal air barrier system. 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, Wraptite was applied externally, quickly and easily to the Siniat Weather Defence Board in continuous pieces. The membrane fully bonds to virtually any substrate, requiring no mechanical attachment, seals or tapes to suppress air leakage around junctions or penetrations.
