Passive House Pioneer

ECOWINDOWS is a pioneer in the field of Passive Houses. In 2011, we manufactured New Zealand’s first certified Passive House windows. And in 2012, the first-ever Passive House in New Zealand was built with our high-performance windows and a controlled ventilation system that helps keep the house dry, warm and comfortable all year round.

Ever since, we have supplied components for various Passive Houses across New Zealand and continue to work on numerous Passive House projects each year.

If you would like to learn more about our components for Passive House building or discuss your building project, please do not hesitate to contact us today.

We look forward to hearing from you!
