Wet Tropics

This region roughly corresponds to NCC/ABCB Climate Zone 1 and contains the capital city of Darwin, as well as the population centres of North Queensland. The vapour drive is inward.

External Wall Wraps for the Wet Tropics (vapour drive inward) are selected based on vapour barrier performance, with the highest vapour resistance preferred.


Design and Build To Suit Your Climate Zone

The following product matrix is a hierarchal guide for selecting products for residential and commercial building applications for the relevant ABCB climates zones.

Condensation Risk in Walls – Hygrothermal Analysis

Interpreting condensation risk

When the temperature is lower than the dew point condensation will form. When the Temperature profile and Dew Point lines intersect this is the location point of the condensation in the wall.
