Passive House

Paarhammer triple glazed windows and doors were used in one of Australia’s first passive houses built in Castlemaine, Victoria.

A movement that first began in Germany in the late 1980s, passive houses are ultra-low energy buildings, designed and built with a low or even negligible ecological footprint. There are currently about 25,000 to 30,000 passive houses all over the world.

Designed by Danilo Paglialonga together with owner Karl, the passive house was built to provide an affordable home that could meet the environmental challenges of a changing climate at minimal cost to the planet. The key strategies followed to achieve this objective included low embodied energy, renewable resources, recyclability, minimal waste, and minimal need for ongoing heating and cooling.

One of the requirements of the passive house standard is very little energy consumption (less than 120kWh/m² per year) and very low air infiltration. Excessive air leakage leads to unnecessary heat loss or gain and discomfort. Paarhammer products use a multi-point locking system for windows and doors, which is almost airtight and increases the safety aspect as well. Low air exchange also means higher energy efficiency and much lower energy bills, a win for the owners and the environment.

Paarhammer has since joined Passive House Australia

The efficiency values of the windows from Paarhammer are very impressive, their least efficient product is more efficient than most other suppliers best performing products.

We live on a windy site, high up on a hill and three previous doors made by others all failed, but not the Paarhammer entrance door; secure, draft proof, looks amazing and everyone that comes to our house comment that it is the best looking door and we love it. Thank you again.

Our windows and doors are beautiful. Also, the temperature in the house is very stable between day / night as well as winter / summer, which makes it extremely comfortable and saves on energy costs. Thanks to the team at Paarhammer!

We have had lots of positive comments, and everyone who comes here just loves the sliding doors!

Paarhammer really helped to reduce the stress of building. They were happy to discuss window and door options and looked at it with our needs in mind. We now have a house that we call home.
