Frequently Asked Questions
Answers to the questions we hear most often about UPVC windows and doors.
UPVC (unplasticised polyvinyl chloride) is a rigid, weather-resistant plastic material. It's widely used for windows and doors because it doesn't rot, rust or corrode, holds its shape well, and needs very little upkeep compared to wood or metal frames.
Well-fabricated and properly installed UPVC windows are built for long-term use, often performing well for decades with basic care. Actual lifespan depends on installation quality, climate exposure and maintenance.
Yes. The multi-chambered profile and sealed glazing reduce heat transfer, which helps keep interiors more stable across seasons and can ease the load on heating and cooling.
Very little. Unlike wood, UPVC doesn't need repainting or sanding. A periodic wipe-down with mild soap and water, along with occasional lubrication of hardware, is usually enough to keep them working smoothly.
Sealed multi-chamber frames and glazing help dampen sound transfer, making interiors noticeably quieter compared to older or poorly sealed window systems — helpful for homes near busy roads.
