This post-war Greensborough weatherboard had broken springs, seized sashes and drafts pouring through every room, so we replaced all 20 openings with argon-filled, Low-E double glazing in white uPVC frames with Ovolo profiles and Georgian bar detailing, delivering a home so thermally efficient the owner disconnected from gas heating entirely.
"If you're spending that amount of money, you need to trust the company — and with Nu-Eco, I did."
Trivess didn’t approach this project like a typical homeowner. As a sustainable housing researcher at RMIT University, he evaluated every double glazing company, frame material and glass type with the same rigour he brings to his professional research. After comparing multiple providers, he chose Nu-Eco because the information was clear, verifiable and backed by documentation.
Nu-Eco managed the full scope across 20 openings in a single stage, covering every room in the home including office, living areas, dining room, kitchen, bedrooms, bathroom, toilet, laundry and the front entry. Casement windows with restrictor stays and shootbolt locking were specified throughout, with 18mm white Georgian bars added to selected windows to complement the home’s updated Hamptons-inspired exterior. The office received a tall four-pane casement configuration, while the living room and TV room were each fitted with outward-opening French doors flanked by matching casement sidelights. Gold lever handles were specified across all doors for a warm, traditional finish.
The front entry was designed as a feature: an inward-opening composite door in Turnberry Anthracite with Reflections glass panel and a gold lever handle, creating a strong first impression against the white weatherboard. Privacy glass was specified for the toilet and bathroom windows.
Every frame was finished in solid white uPVC with an Ovolo profile and KDHW timber reveals throughout. All glazing was specified as 28mm argon-filled, Low-E insulating glass, delivering the thermal performance Trivess needed to eventually disconnect the home from gas heating entirely. Two glass panels required replacement after installation due to minor scratches, one identified by Nu-Eco, one by the customer, and both were replaced immediately without question.
Five years on, Trivess reports the windows still look and operate exactly as they did on installation day. The home is warmer in winter, cooler in summer, quieter, and better ventilated in every room, including spaces that previously had no operable windows at all.
A post-war weatherboard cottage in Greensborough with original timber double-hung windows that had failed on almost every level. Springs were broken, sashes wouldn’t open, seals had deteriorated, and drafts were constant. Several rooms had no ventilation at all, creating stuffy, uncomfortable spaces with poor indoor air quality. The home relied on gas ducted heating that ran overnight in winter but still couldn’t deliver consistent warmth, and energy bills reflected the inefficiency. As a sustainable housing researcher, Trivess knew the windows were the single biggest performance gap in the building envelope.
Trivess wanted windows that genuinely performed — not products dressed up with marketing claims he couldn’t verify. His priorities were improving thermal comfort year-round, restoring ventilation to every room, reducing energy consumption, and finding a provider whose information was clear, independent and backed by documentation. He evaluated multiple companies and frame types, but found most relied on sales-driven messaging and couldn’t substantiate their performance claims. He also wanted a product that would last — spending this amount on something that deteriorated in five years was not an option.
Nu-Eco replaced all 20 openings with FORCEFIELD UPVC frames and 28mm argon-filled, Low-E double-glazed units. Casement windows with restrictor stays and shootbolt locking were installed throughout, with 18mm Georgian bars in selected windows for architectural detail. French doors with gold lever handles opened the living room and TV room to the outdoors. A Turnberry Anthracite composite entry door with Reflections glass created the feature front entrance. Privacy glass was specified for the toilet and bathroom. KDHW timber reveals were fitted throughout, and the full project was completed in a single stage, with minor glass replacements handled promptly and without question during aftercare. Five years later, the home has disconnected from gas heating entirely, energy bills have dropped significantly, indoor air quality has improved, and every window still operates like new.
