BRANZ Appraisal

Check below to view our appraisal from the Building Research Association of New Zealand. They want a building system that deliver better outcomes for all. And we’re on board (pun unintended!). Our Vinyl Cambridge and Cedarline profiles have been rigorously tested and BRANZ appraised in New Zealand.

We believe kiwis should get the best out of there homes, and strive to make a difference.

Vinyl Cladding conforms and surpasses certification standards in New Zealand and many other countries.
