Double hung windows feature two operable sashes that slide vertically within the frame. Both the top and bottom sashes can be opened independently, providing flexible ventilation and a classic appearance that suits both traditional and modern homes throughout Dandenong and Victoria.

Double hung windows offer excellent ventilation, easy operation, and space-saving functionality since they don’t project outward when opened. They are ideal for rooms facing walkways, patios, or decks and provide a timeless style that complements a wide range of home designs.

Yes. Modern double hung windows can be fitted with double glazing, Low-E glass, and weather-resistant seals to improve thermal insulation and reduce heat transfer. This helps maintain indoor comfort and can contribute to lower heating and cooling costs in Victoria’s changing climate.

uPVC stands for unplasticised polyvinyl chloride, a durable and low maintenance material commonly used in modern window and door frames.

Unlike traditional materials such as timber or aluminium, uPVC does not rot, warp or corrode over time. It provides excellent thermal insulation, helping improve energy efficiency while also reducing outside noise.

Because of its durability and low maintenance requirements, uPVC is widely used in high performance window and door systems around the world.
