Cost-Effective Dristud Wall Wrap Exceeds NZBC Requirements

Affordable housing for families has been an important factor in the recent push in the building sector. There are various reasons given for the housing crisis, however housing families in affordable and healthy homes is the key. Understanding of building science has improved over the years and designers are able to create healthier homes that are affordable by using quality materials in the right applications. Finding the right quality products at affordable prices is another challenge altogether.

The growth in the building industry has flooded the market with too many similar products and builders are left wondering which ones to use. 

When it comes to wall wraps, there are a few on the market at various price ranges and most of them have BRANZ or CodeMark certification. However, that does not necessarily mean the products meet all of the technical properties required by the New Zealand Building Code in every application. For example, some products cannot be direct fixed to all wall claddings and also cannot be used on gable ends. Builders need to be aware of the limitations of use.

DriStud Wall Wrap is a universal wrap which outperforms the requirements of the NZBC at a very competitive price. It is fire retardant, can be used on gable ends, and can be direct fixed with all claddings including non-absorbent materials. DriStud's competitive pricing does not affect quality, so builders can be relaxed using it, knowing that it will perform.
