What Thermalframe does

Thermalframe is a New Zealand-owned, family-operated manufacturer and installer of European uPVC double-glazing windows and doors, headquartered in Lower Hutt, Wellington. Founded in 1992 under the legal name European Profile Company Ltd and rebranded to Thermalframe in 2007, the company exclusively uses the Liniar uPVC profile system sourced from the UK and works closely with Metro Performance Glass for glazing units. Its product portfolio spans awning, casement, sliding, bay, and tilt-and-turn windows; sliding, French, and front/back doors; and glass upgrades including Low E, laminated, tinted, and privacy options. Technical differentiators include multi-chambered PVCu profiles, co-extruded seal technology, multi-point stainless steel locking systems, fusion-welded mitre corners, and argon-filled double/triple glazing with 16-20mm thermal spacer bars.

The company operates a direct-to-consumer sales model with an in-house trained installation team, supported by a physical showroom in Alicetown/Lower Hutt. Pricing is quote-based with a staged payment structure (25% deposit, 50% on manufacture start, final 7 days after installation) and a 4-7 week production lead time. Its primary customer segments are residential homeowners in three categories: Character/period homes, Classic homes, and Contemporary homes; secondary segments include New Build Projects (architects/builders) and Replacement/Retrofit Projects. Marketing relies on the website, project galleries, showroom visits, and direct quote requests.

Thermalframe is privately held by its founding family with no institutional funding, subsidiaries, or acquisitions. Marquee reference installations include Scott Base in Antarctica and various New Zealand ski lodges. The company employs approximately 9 people and operates exclusively within New Zealand, with the Wellington Region as its historical base and growing reach across the country.

• Pella Corporation: Major North American window and door manufacturer with broad product portfolio. Comparable in offering high-performance window systems for residential customers, though at much larger scale and broader geographic reach.
