Air Tightness

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.

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.
