DuPont™ Tyvek® UV Façade offers discreet protection for a contemporary and sustainable timber-clad new build in Bristol

Tyvek UV Façade

May 2015 – An elegant open-jointed façade design demands not only high-performance protection but also a discreet subtlety that will not compromise the aesthetic vision. Thus when Point1 Building Systems were tasked with installing an attractive western red cedar cladding system to a residential extension conceived to blend with its environment, DuPont™ Tyvek® UV façade was the obvious choice of advanced breather membrane.

Created especially for such applications, DuPont™ Tyvek® UV Facade was developed using the same unique technology that has made DuPont™ Tyvek® the market leading breather membrane. This innovative solution allows for greater freedom and confidence when designing ventilated facades and reliably protects against wind, water, interstitial condensation and air-leakage, while being resistant to UV damage and offering an entirely black finish. DuPont™ Tyvek® UV Facade bears the CE mark in accordance with EN 13859-2 and rigorous testing has shown it can withstand UV exposure for a very significant length of time.

The new structure is a two storey contemporary addition connecting to a period coach house in Long Ashton, Bristol, and is a self-build project designed to give the owners increased living space for their growing family. DuPont™ Tyvek® UV Façade has been installed directly behind the timber cladding and entirely wraps the structure, including the pitched roof.

DuPont™ Tyvek® Butyl tape was used to seal penetrations and DuPont™ Tyvek® UV Facade tape to seal the laps. Excellent thermal efficiency and airtightness were crucial factors in this environmentally conscious project, which has been built using the fully insulating Kingspan Tek SIPS system and which also features air source heat pumps and triple glazed panels.

Garry Dyke, Director of Point1 Building Systems explains, “The cladding was not continuous and therefore we needed a completely black, waterproof and UV-resistant breather membrane that would not be seen. DuPont provided excellent technical support and really helped us to develop the specification for installing the membrane. We positioned counter battens vertically up and horizontally across the roof slope to accept the 44 x 18mm Western Red Cedar Cladding. We then laid battens over counter battens, also all stained black in order to match the subtlety of the membrane.”

Garry continues, “Our installation team found this to be a very robust membrane that was easy to work with, what’s more DuPont offers a good range of supporting seals and trims to assist in minimising puncturing etc. Altogether this is a superbly insulated project, in addition to DuPont™ Tyvek® UV Façade and the Kingspan TEK142 wall and roof panel system, we also installed a 25mm layer of TP10 (Thermapitch) to further reduce thermal bridging and improve heating response times. Overall we have achieved impressive through wall U-Values of 0.15W/m².k.”
