Advanced membranes from DuPont offer a holistic solution to air-tightness and moisture control for new holiday homes from Haulfryn

The romance of the beach house is undeniable, but even the most beautifully constructed designs, such as those by Lissett Homes for a seaside leisure park operated by The Haulfryn Group, must withstand the harsh realities of a coastal climate. Furthermore in today’s cultural climate of sustainability, quality construction must also aim for both optimal energy-efficiency and indoor comfort. 

So the newest holiday homes at The Warren in Abersoch benefit from an air-tight, thermally efficient, weather-proof envelope courtesy of advanced membranes from DuPont Building Innovations. In fact, the superior specifications for these ultra-desirable chalets exceed the regulations for holiday home construction, aiming for the highest standards of sustainability, reliability and comfort.

The ‘holistic’ overview was for the building envelope to work in harmony with features such as a heat recovery system and this involved the optimising combination of DuPont™ Tyvek® breather membranes (in two different types) and DuPont™ AirGuard® air and vapour control layer to create a durable barrier against wind, water and interstitial condensation. The lightweight timber frame structures were assembled and sealed off site and delivered to Haulfryn ready for smart interior finishing and external landscaping.

DuPont™ Tyvek® Enercor Roof and DuPont™ Reflex Wall (both metallised for high reflectivity and very low emissivity) offer excellent protection against radiant heat loss in winter and excessive gains in summer, and are reliably water-tight while allowing any trapped interstitial vapour to diffuse through the unique membrane structure. In partnership with DuPont™ AirGuard®, a metallised layer with even lower emissivity which prevents air and vapour leakage from the interior into the structure, these products significantly enhance the integrity and thermal performance of a building.
