Passive House Designers

In New Zealand we have got some  very good INDEPENDENT PASSIVE HOUSE DESIGNERS who provide impartial advice to clients and offer the best option for you and your project and not the best option for the Passive house designers wallet.

As some Passive House Designers  gave up their independence and now compete with ThermaDura we recommend to contact ThermaDura directly to get a free quotation for New Zealand manufactured certified passive house windows. We can also provide you with recommendation for Passive House Designers who are still independent in your area.
