All Natural

Perched high on top of rocks, like a birds nest, this build was a challenge. More so since the clients wanted to take in the gorgeous views which necessitated extra-large windows, doors and fixed panes. The build consists of three main parts that are connected with glazed walkways, which allow views and solar gain for every room. Timber was a must-have as the window frame material due to its sustainable features: it re-grows and stores carbon for life, it improves health and well-being, and cuts energy bills while simultaneously blending beautifully with the natural sandstone and timber cladding.

Double glazed units with low-E were used for very high energy efficiency, so the heating and cooling will be negligible, further reducing greenhouse gas emission and improving thermal comfort. Reducing of the carbon footprint has a positive impact on the environment. For this project we manufactured and installed tilt & turn windows, lift-slide doors, stacker sliders and corner windows, fixed glass units and hinged doors. All are double glazed with low-E glass with 16mm argon filled space, resulting in U-values of 1.8 or less.

The timber is Victorian Ash, plantation grown in Gippsland. Frames were dipped into a preservative and factory spray-painted with specially formulated water based coating before German multi-point hardware, seals and IGU’s were installed. It was very important for the client to be able to enjoy the views with as little interruptions as possible. Some of the units therefore were 3970mm wide by 2200mm high, each weighing 420kg and had to be installed by crane. Also, extra-large 3 part stacker sliders (7570mm x 2200mm) open up the gymnasium which was built underneath the tennis court.

High performance was a main reason for the clients and architect choosing Paarhammer products, in this case with WERS ratings from 5 cooling to 7 heating stars and energy savings from 65% to 75%. Very low U-values combined with extra low air infiltration – no drafts - offered the solution the clients and architect wanted. The ability to provide high energy ratings for extra-large sizes was a key component for selecting Paarhammer products.

The Paarhammer windows and doors reduce heat loss and improve thermal comfort while maximising daylight transmission. Complexity of this project included huge double glazed units, enabling expansive views, and light and openness without the need for window coverings due to very high energy efficiencies. High winter heat gain increases comfort levels and decreases the need for heating. The house design and use of low-E glass also ensures the house stays cool in summer.

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.

Lilly C.

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!

Mark D.

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.
