Drier Education: An Insight into the MOE's Weathertightness Design Requirements

In this article, we'll explore the new elements in Version 3.0 of the Ministry of Education's Weathertightness Guidance.

Above Sheathing Ventilation – Part 3: Fighting the Sun

In Part 2 of this series, our brave new roof used Above Sheathing Ventilation (ASV) to battle the dark forces of winter. But summer brings another set of challenges.

Above Sheathing Ventilation – Part 2: The Blue Planet

Above Sheathing Ventilation (ASV) facilitates roof drying by using the same physics that creates rising clouds on the surface of the Earth.

Thermoplastic Elastomer Ether Esters: What are they, how do they work?

Exterior membranes for roofs and walls by pro clima incorporate a monolithic Thermoplastic Elastomer Ether Ester (TEEE) film.

Above Sheathing Ventilation – Part 1: Rise of the Cavity

Above-sheathing ventilation (ASV) uses solar energy to induce airflow between the cladding and the membrane by heating the roof cladding and warming the air in the cavity below.

Fire Testing for Temporary Wall Cladding

A look at how a peel and stick weathertightness membrane performs in a fire when used as a temporary cladding.

Renovating and Insulating Masonry Walls

Why strapping and lining masonry walls on the inside is not a good idea, not for renovation or new builds.

Adding Insulation and Wall Underlay to Existing Walls

How can we safely add insulation to existing walls without risking trapped moisture and compromising durability?

Achieving Winter Warmth in New Zealand Homes

Common themes with comfortable high-performance houses are insulation, airtightness, ventilation and heating.

Water Resistant vs. Watertight

Protecting the structure from moisture before, during, and after construction is a code minimum requirement for B2 durability.

Where Does the Airtightness Layer Go?

In New Zealand, it's crucial to get building layering right for summer and winter. Modern buildings include an intentionally airtight shell to conserve energy, whether for warmth or coolness.

Triple Connected Windows - Part 2

It is very important that all aspects of the window are taken into consideration, including the frame system, double glazing, window size, and the connections between the window and the wall.
