Like with any external building product that contains timber or absorbent materials, SIPS can be sensitive to moisture.

H1 provides for the efficient use of energy and sets physical conditions for energy performance. Are the recent changes to the H1 clause just a small step along the road to adopting the International Passive House standards across New Zealand, like other members of the OECD experienced? Robert Whitehouse believes they are.

When it comes to understanding the flow of liquid water, air, heat and water vapour through our building elements, accurate nomenclature matters.

Harsh summer conditions expose roofs to severe solar radiation and add uncomfortable heat loads to our buildings. But the air movement induced by ASV can work to keep our buildings cool, no matter the cladding type or material colour.

A look at the impact of water from the outside, the inside and within our buildings, and how above sheathing ventilation can keep the structure dry using proven building physics.

An introduction to Above Sheathing Ventilation (ASV) and some of the issues it helps to resolve. 

TEEE membranes actively transport water vapour through molecular diffusion across the thickness of the TEEE film.

A guide to Above Sheathing Ventilation (ASV) and how it can significantly reduce moisture accumulation and assist with condensation management.

The Ministry of Education's updated guidelines on Weathertightness Design Requirements for New School Buildings outline new changes in the design philosophy of school roofs set well above NZBC Acceptable Solutions. 

Knowledge about the fundamentals of adhesion technology and about the loads that will actually be acting in practice is crucial in order to be able to carry out reliable project planning and testing.
