DriSpace Brings Compatible Weather Protection and Ventilation Systems to NZ

Recent research shows that internal moisture and condensation in the roof space is a widespread and growing problems across New Zealand. Passive ventilation is a method of allowing continuous airflow into a building above the thermal envelope and minimises internal moisture from the roof cavity and prevents condensation and mould from forming. DriSpace Systems offer comprehensive and easy to follow vented roof and wall systems and allow specifiers, designers and architects to choose the right systems and components in a simple manner.
