The completion of a stunning new Hilton hotel at Silverstone leads the way in superior high-performance with Wraptite external airtightness barrier.
KKA Architecture designed the hotel with Metclad Contracts appointed as the specialist envelope contractor for the project. Wraptite airtightness membrane from the A. Proctor Group was selected by Metclad to maximise airtightness and energy efficiency.
Wraptite self-adhesive breather membrane is applied externally, quickly and efficiently as part of the rainscreen system. Incorporating the Wraptite System helps ensure “as-designed” performance. Its inclusion narrows the gap between as-designed and actual energy performance whilst reducing the likelihood of possible failures to meet required airtightness levels.
Traditionally, air barriers have been fitted internally but this necessitates accommodating building services such as electrical, lighting, heating and drainage systems, thereby increasing the gap between as-designed and built. However, the Wraptite membrane fully bonds externally to virtually any substrate, requiring no additional mechanical attachment, seals or tapes to suppress air leakage around junctions or penetrations.
The high vapour permeability of Wraptite allows the substrate beneath to dry quickly and moisture vapour to escape and reduces the likelihood of mould, mildew, condensation, timber distortion and metal corrosion.
Wraptite is the only self-adhering vapour permeable air barrier certified by the BBA and combines the critical properties of vapour permeability and airtightness in one self-adhering membrane.
