What Thermeco does

Thermeco is a family-owned Australian window and door manufacturer headquartered in Rowville, Victoria, founded in 1981. The company designs and produces thermal break, energy-efficient aluminium, steel, brass, and minimal window and door systems for high-end residential projects across Australia and New Zealand. Thermeco holds exclusive Australian and New Zealand distribution rights for Italian manufacturer Secco Sistemi's premium steel and brass systems (OS2, 4F curtain wall, OG Zero Gravity magnetic levitation lift-slide, BV75), and also offers the Keller minimal windows range alongside its proprietary EC aluminium series (EC35TB through EC115TB, including the EC125 AluSteel hybrid). The company's core technology is thermal break engineering, with the EC65TB achieving U values as low as 1.5 for fixed windows and the EC35TB and EC115TB certified to BAL40 bushfire rating.

The business operates a channel-led go-to-market model. Architects and designers specify Thermeco products during project design, after which a national network of 13+ authorized fabricators across Australia and New Zealand purchase, fabricate, and install the systems on those projects. Pricing is custom per project based on specifications, dimensions, and configuration, with no public price list; the billing relationship is multi-year as projects move through design, fabrication, and installation. Marketing is largely top-of-funnel and content-driven: an extensive project gallery, social media presence across Facebook, Instagram, LinkedIn, and Pinterest, an email newsletter, and earned coverage in architectural publications such as The Local Project. Customer concentration is dispersed across luxury residential developments, with named architects including Travis Walton, Vibe Design Group, Cera Stribley, DX Architects, Carr, and Aktis featured across project case studies.

The company differentiates on three pillars: proprietary thermal break technology combined with European hardware quality (via Secco Sistemi partnership), B Corp sustainability certification covering circularity, environmental footprint, and stakeholder welfare, and BAL40 bushfire-rated product variants. A 600m2 factory extension completed in 2019 expanded the existing 1,200m2 manufacturing facility, and 2025 industry recognition includes the AGWA Design Award and AusFenEx25 Highly Commended. Ownership remains with the founding Costabile family (Carl Costabile as Managing Director), with no external institutional capital, funding rounds, or M&A activity disclosed.
