NZCB Select Pro Clima Underlays for New Head Office

When the New Zealand Certified Builders Association decided to build their new head office, they chose pro clima's SOLITEX MENTO and EXTASANA exterior wraps to provide the best protection from wind, rain and UV with exposure for up to 90 days.

These wraps 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 an 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.

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