Thermawood Otago Launches Website for Retrofit Double Glazing Across Otago and Southland

Thermawood Otago has launched a new website, www.thermawoodotago.co.nz, setting out its retrofit double glazing, timber window restoration and heritage window services for residential and commercial properties across Dunedin, Otago, Central Otago and Southland. PRLog published the announcement on October 27, 2026.

What the Thermawood Otago Website Covers

The site describes a New Zealand-designed, patented system that upgrades existing timber windows and doors without replacing the original joinery. According to the announcement, the system is intended to reduce heat loss, condensation and outside noise while preserving the character of homes and heritage buildings. It features purpose-designed drainage and Warm Edge technology to protect timber and glass while supporting thermal performance.

Existing timber and aluminium windows can be upgraded with double glazing to improve comfort, cut heat loss and outside noise, and minimise condensation without full window replacement. Ageing or damaged timber windows can be repaired and restored as part of the upgrade, with issues such as timber rot, draughts and window operating problems addressed to prepare the joinery for double glazing. Traditional windows and doors, including sash windows and leadlight features, can be restored and upgraded while preserving the architectural character of heritage homes and villas.

The company says retrofit double glazing keeps interior glass surfaces warmer, reducing window condensation and limiting moisture build-up on the glass. Customers can view completed retrofit double glazing, timber restoration and heritage window projects in an online gallery. The announcement directs property owners to contact the team to discuss an upgrade, arrange an assessment of existing windows and request a quote.

Thermawood Otago's Certification and Regional Coverage

According to akta.pro company records, Thermawood Otago obtained NZ Standard 4211:2008 certification for the Thermawood Retrofit Double Glazing System, claimed as the only retrofit system of its kind on the New Zealand market to hold this standard. The same records show the company established a Central Otago branch office at 13 Hughes Crescent, Cromwell, managed by Aaron Waldron, extending service coverage beyond the Dunedin headquarters, and formed a partnership with a local leadlight restorer to offer integrated heritage window restoration and double glazing services.

The records list Thermawood Otago as a member of the Window & Glass Association of New Zealand, serving residential and commercial customers throughout Otago and Southland, including Dunedin, Invercargill, Cromwell, Oamaru, Gore, Waitaki, Balclutha and Maniototo. The business is backed by more than 30 years of combined experience in the glass and timber joinery industry, with owner Matt Lamb holding over 20 years in the glass and joinery industry and Aaron Waldron over 20 years in the glass industry.
