Our story
Founded in 2006, we’ve grown into one of New Zealand’s most trusted façade remediation and industrial abseiling contractors – with a large, IRATA-trained team and a reputation for delivering high-quality outcomes in complex environments. Our technicians provide cost-effective access to even the most challenging sites – offering everything from leak detection through to full exterior painting and major repairs.
As demand for our specialised expertise continues to grow, we remain focused on what matters: technical expertise, prompt delivery, nationwide service, and trusted advice.
The Pro Clima weathertightness system includes:
SOLITEX MEMBRANES
For roofs, walls, and façades.
SYSTEM-SPECIFIC TAPES
For seams, junctions, and penetrations.
PRIMERS AND SEALANTS
To ensure adhesion on various substrates.
INSTALLATION ACCESSORIES
Such as preformed corners and pipe gaskets.
Barriers
System-based performance.
Together, these components form a continuous, breathable barrier that supports energy efficiency, interior comfort, and building longevity.
SOLITEX EXTASANA® is a UV stabilised and tear resistant weather resistive barrier (WRB). It contains a non-porous, water resistant TEEE film that is laminated at high temperatures between two layers of spun bonded polypropylene.
This product is designed for use behind most typical wall cladding systems, including cavity brick, fibre-cement, masonry, and other common wall systems. It is suitable for use in BAL regions 12.5 to 40 in accordance with AS 3959.
- 180 days UV resistance & long-term durability
- Highly vapour permeable (Class 4)
- Weathertight & airtight weather resistive barrier (WRB)
- Next generation non-porous monolithic technology
