Climate-responsive hygrothermal modelling
for building envelopes

Better Building's moisture analysis workflows offer dynamic, HAMT-based hygrothermal simulations to predict how heat and moisture interact within building envelopes over time. Define real-world climate conditions, choose from trusted material data, and assess risks of condensation, mould, and material degradation. Equip your design with reliable forecasts that enhance occupant health and structural durability.
