For those of you using the BRANZ House Insulation Guide, you’ll be pleased to know they have brought out a new edition with nearly 50 percent more construction options and 28 new pages of information.

If you have ever pondered what efflorescence is and how it affects the specification of a concrete, particularly for underground areas I am here to answer your questions.

Ah, the age old question.  Hopefully this post will give you some insights as to why this happens.

Recently I received a panicky phone-call from a friend. 

The use of downlights in ceilings reduces the effectiveness of ceiling insulation and needs to be accounted for when meeting NZBC H1.

Recently we were asked to assist with the preparation of a paint specification for a Green Star building and the project team wanted to ensure that we gained the maximum points on offer under IEQ3 and Matt3 in relation to paint and coatings.

With James Hardie's Linea™ Weatherboard you can achieve up to a 90 minute fire resistance rating.

Over the past year or so, the majority of the insulation queries I have received concern the changes to NZBC H1 and how to use the Calculation Method.

A Dulux AcraTex Texture System is permanent. Like all surfaces exposed to the elements, preventative maintenance will keep it looking its best and preserve its optimum performance over a longer time span versus a cement render painted finish.

The genesis of the acrylic texture industry was actually the limitation and failings of cement renders resulting in the development of what we now know as Acrylic Texture Systems.
