Expandify wall systems include an integrated breathable waterproof membrane and sealed sandwich panel joints to minimise internal condensation.

Moisture control is achieved by:

PU and Rockwool composite wall panels that resist moisture transfer

Internal vapour barrier layers within the wall panel system

CNC-machined joints sealed with anti-corrosion treatment and sealant during installation

Proper site ventilation and window use are still encouraged to support natural air exchange.
