The completion of a stunning new Hilton hotel at Silverstone is another step
nearer and leads the way featuring the superior high-performance Wraptite
external airtightness barrier.
The impressive new hotel, located trackside, overlooks the starting grid for the
home of the iconic British Grand Prix. Facilities include 197 guest rooms, a rooftop
terrace and the offer of race-day hospitality experiences.
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, specialists in supplying
high-performance products to protect buildings, was selected by Metclad to
maximise airtightness and energy efficiency, perfectly balanced with the crucial
requirements of vapour permeability
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 asdesigned
and actual energy performance whilst reducing the likelihood of possible
failures to meet required airtightness levels.
Traditionally air barriers have been fitted internally. The internal installation of an
air barrier 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. Quite simply, providing a winning performance in
advanced membrane technology for buildings.
