Frame Fast is seeing a sharp rise in demand for flat roof windows as homeowners increasingly seek light-filled extensions and open-plan spaces. Once considered a niche product for high-end architectural projects, flat rooflights are now a standard feature in everyday kitchen refurbishments, rear additions, and single-storey extensions, according to the company.
“Adding space without adding natural light no longer makes sense to homeowners,” says Jason Pascoe, general manager of Frame Fast’s Aluminium Division. “Flat roof windows deliver brightness, a sense of openness and a design statement that installers can easily offer as an upgrade.”
Global forecasts reflect this shift, with the flat roof window market expected to surpass $230 million by 2030, growing more than 4 percent annually. In the UK, planning constraints often favour flat roofs, making rooflights the simplest way to bring daylight into new living areas, says the company.
Frame Fast manufactures its own flat roof window system at its Derby facility using the Aliver Rooflight from Smart Systems. The aluminium frame is thermally broken, supports double or triple glazing, and achieves U-values as low as 1.0 W/m²K. Units are fully fabricated for straightforward installation and feature a clean, minimal finish with no visible internal fixings.
Jason adds: “With Frame Fast, installers benefit from dealing with a single, reliable supplier across all glazing requirements.”
