Pro Clima Promo Winner Puts Certified Building Wrap to Good Use

Adroit Builders are the proud winners of two rolls of SOLITEX EXTASANA building wrap — branded for Certified Builders’ members. The Pro Clima team met with Oscar Williams of Adroit at his latest build in Puhoi to find out a little more about the project — and also happened to meet Oscar's clients.

David Kelly, Chairman of Zeald, and his wife Lisa are building their family’s dream home on a scenic rural plot of land. The first building on their site is a shed/man cave/minor dwelling. Lisa isn’t too fussed on having a man-cave first, but is happy to tolerate this — the family will live in the building while they build the main dwelling. Oscar approached David with the option of using pro clima’s SOLITEX EXTASANA CodeMark approved building wrap which he jumped at. Oscar and his building partner Matthew Hanna have used these products in the past and are pleased to be able to rely on them again.

These building underlays are non-porous and have been tested to resist more than 10,000mm of water column pressure. SOLITEX building wraps are at the same time extremely vapour open with a moisture vapour transmission rate (MVTR) of 0.75MNS/g and will actively dry out the framing and insulation layer. These wraps work in combination with the TESCON range of flashing and sill tapes and ROFLEX and KAFLEX penetration seals to complete the weathertightness layer. The question was asked, “Why do I need 10,000mm of weathertightness?”. Of course the answer is "You don’t." However, knowing it is actually watertight is the point — unaffected by washing the building with detergents, timber treatments, wind pressure (it’s windtight too). Adroit Builders have confidence in the performance of the products for the construction period and for 50+ years.

CodeMark certified, SOLITEX EXTASANA is now available to Certified Builders with the new NZCB logo printed onto it.
