Extreme Performance
Three is better than Two, and while Triple Glazing is still not seen as mainstream in NZ, E13 Windows have become specialists in harnessing what it can offer.
With an extra pane of glass comes the added benefit of another surface to apply high performing Low E coatings, as well as another cavity between panels for even further insulation, not to mention the added bonus of noise reduction.
We partner with our suppliers to bring leading solutions to the age-old problem in NZ, where the windows were the weak link in insulation.
Savings long term
A fundamental principle of Passive Housing, an air tight home is easier to heat/cool and ensures building products last longer, meaning less energy is used and less maintenance is required.
As warm air moves through your home, it finds gaps in materials and cool surfaces to condensate upon, promoting mould build up. Sometimes these surfaces are unseen or covered, and over time can lead to costly repairs.
E13 Windows continues to lead the industry, partnering with local experts, achieving high level results.
Another basic principle of Passive Housing is to have any Thermal Breaks forming a continuous line in the home - so that they can't form a "Bridge" over each other. For windows this means having the Thermal Break align with the wall insulation, or recessing the window frame as much as possible.
This decreases the Dew Point of a window, enabling further reduced condensation but also decreasing the opportunity for mould to form.
At times this is difficult to achieve under NZ building standards, however you can best achieve this with our systems and how the Thermal Breaks align.
Whether you are wanting greater thermal performance or building an architectural home, we've got more than 20 years of expertise and experience in delivering superior triple glazing window solutions throughout New Zealand.
A long-standing Otago business with family origins, Michael and Kathryn Brenssell has been hands-on in the business for 20 years and are proud of the reputation they have built for producing joinery that makes a difference. After operating as Vistalite Otago providing services from everyday residential homes to recreational and commercial properties, we felt it was time to recognise our achievements and develop the stand-alone brand E13 Windows for our future.
We cater to the harsh climates of Central Otago and the South Island and the contrasting difference in parts of the North Island warmer climate. After starting a business with cottage building for architecture homes in Dunedin, Michael saw the potential in providing window and door solutions that added to the aesthetics of these homes while offering great thermal performance, a combination necessary in the South, home of spectacular views but harsh winters. With their ability to create airtight homes without compromising on the style proving a success in Dunedin and the greater Central Otago region, they are now offering sophisticated and versatile triple glazing window solutions throughout New Zealand.
