Dampness due to condensation can lead to fungal growth which harms occupants, causes decay in structural timbers and accelerates corrosion of metal components and fixings. 

The best way to prevent roof leaks in the wetter seasons is to be proactive with roof maintenance in the months before the winter period.

One of the more significant developments in low slope commercial roofing in the New Zealand market in recent years has been the rise of ‘cool roofs’. Relatively new in our country, the choice to adopt lighter coloured roofing membranes is becoming more popular.

It is important to consider NZ's unique environment and high UV levels when specifying modern single ply thermoplastic membranes such as PVC and TPO.

To understand insulation and its thermal resistance values, you need to know about thermal conductivity, thermal resistance and thermal transmittance.

Traditional 'cold-roof' construction of flat roofs in New Zealand is being challenged by the thermal and performance benefits of warm roof systems.

Green roofs or living roofs are an obvious, visible and celebrated device in sustainable design. They offer both ecological advantages and some design challenges.

The peace of mind and long-term savings gained from selecting a more reliable membrane system is often underestimated.

PIR insulation board is a multi-functional product that can be effectively installed in various areas of a build for high performance insulation.

While ventilation helps prevent unwanted humidity in the roof space, a comprehensive warm roof system can provide a more complete solution.
