Double-Hung UPVC Window

Double-Hung UPVC Window – Energy-Efficient Simplicity for Every Home

A double-hung UPVC window is the most widely installed window type across North America and a growing favourite in many other markets, valued for its intuitive operation, adaptable ventilation, and straightforward maintenance. With two independently movable sashes — the upper sash sliding down and the lower sash sliding up — the double-hung design allows homeowners to ventilate from the top, the bottom, or both simultaneously, creating controllable airflow patterns that suit different rooms, seasons, and climates. SKATE's double-hung UPVC windows combine the inherently energy-efficient thermal properties of uPVC with robust hardware and a wide selection of profiles and glazing configurations to meet demanding energy codes.

What Makes UPVC the Right Choice

Unplasticised polyvinyl chloride (uPVC) is one of the most thermally efficient window frame materials available. Unlike aluminium, uPVC is a natural thermal insulator — it does not require a thermal break to prevent cold bridging, because the material itself has very low thermal conductivity. This makes SKATE's double-hung UPVC window an excellent specification for projects where maximum energy efficiency, minimum condensation risk, and the lowest possible frame U-value are the primary objectives.

UPVC is also inherently resistant to moisture, salt air, UV degradation, and chemical exposure, making double-hung UPVC windows ideal for coastal, humid, and high-rainfall environments where other materials might deteriorate over time.
