We are often asked whether waterproofing membranes function as vapour barriers. The answer to this question is not as straightforward as with other waterproofing membranes. 

There are many products in the market each promoting their individual thermal performance, but when incorporated into a building the actual ‘real-life,’ performance becomes dependent upon the interaction of all the materials and products used in the construction.

While in the normal course of events, most newly constructed homes in an urban setting can achieve a 6 Homestar rating, if there is an aspiration for higher ratings, then there is value in looking at where points can be gained at an early stage in the design process. 

A collaborative approach is needed to resolve conflicts between fire protection and seismic movement requirements for service penetrations passing through fire-rated walls.

The results of a simple experiment to demonstrate the value of well-fitted curtains.

Continuing from my previous blog and the question of design, I look at considerations for ensuring an effective waterproofing solution. 

Lessons from the design of service penetrations through fire rated walls and floors on a recent high-density residential project. 

As an incentive to sustainable housing, in mid-April the ANZ Bank announced that it is offering reductions to some of its interest rates and fees, subject to particular conditions, if the property being financed has a minimum Homestar rating of 6 stars.

The consultation is on proposals to improve the regulation of building products and methods, strengthen occupational regulation, look at how risk and liability are managed, reduce the building levy, and strengthen penalties for those who don’t comply with the law.
