Appraisal No.979 
With efficient circulation, stale moist air is ventilated outside and fresh air is drawn in. Your insulation works efficiently because it remains dry.
VENT has been New Zealand’s leading specialist in the supply of passive ventilation systems and products for over 5 years and is now here in Australia as VENT Systems. VENT was created as a direct result of the misconception that the ‘Leaky Homes’ disaster that gripped New Zealand was caused solely by external moisture penetration and product failure.
