Triple Glazed

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.

About the

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.
