EXTASANA®
Sommerville Estates is a high-end residential development of 10 multi-storey units in Northpark near Howick. These five-bedroom homes offer 300 m² of living space with top-quality materials. The exterior comprises a combination of pine weatherboard, cedar and Designer Series pre-finished panels from The Brickery (formally NZ Brick Distributors).
How was this project implemented?
When the developer considered the weathertightness of these units, they chose pro clima SOLITEX EXTASANA® Wall Weather Resistive Barrier. This is a non-porous, monolithic building wrap offering complete protection from external moisture and tested for up to 10,000 mm water column pressure.
With excellent UV resistance (90 days exposure), the CodeMark certified SOLITEX EXTASANA® actively moves construction moisture out of the building envelope to keep the framing dry. The product is ideal for use with dark claddings — rated to 120°C; the TEEE functional layer has a melting point close to 200°C.
Airtightness Systems
Vapour check and airtight membranes with humidity-variable diffusion resistance provide the best protection against moisture and mould-infested components. In combination with moisture-active wind-sealing membranes on the exterior, they significantly improve the protection of building components and facilitate a healthier, mould-free indoor environment.
Weathertightness Systems
The SOLITEX wind-sealing system makes building structures particularly energy-efficient and provides effective protection against damage to structures. These high-performance functional membranes are extremely open to diffusion, provide maximum watertightness against driving rain, and actively transport moisture to the outside.
Ideally, they should be combined with humidity-variable airtightness systems on the interior side of the insulation.
