Recent manufacturing data from REHAU reveals an ongoing trend in the rise of flush fit windows, highlighting their continued appeal for residential and commercial projects.
REHAU sold over 358,000 metres of Rio sash in 2024 – a 14% increase on 2023 – while demand for the Rio door launched in 2023 grew by 70% in 2024.
“Rio’s success can be put down to two complementary factors,” says Clare Higgins, Senior Product Manager for REHAU UK. “Firstly, that well-designed frames will always find their place in the market, especially when they offer outstanding aesthetic and energy-efficiency benefits and have plenty of accessories and customisation options.
“But beyond this, Rio’s success demonstrates the enduring popularity of flush fit windows among homeowners and commercial specifiers alike, who are prioritising clean lines to ensure minimal impact on a property’s exterior.”
The new data demonstrates both a continued and recent rise in the number of Rio frames supplied and fitted. Since its launch five years ago, the number of Rio window frames manufactured has grown from 11,666 in 2019 to 89,657 in 2024 – an almost eight-fold increase.
“Demand for the Rio flush fit window frame continues to soar and it is great to see its door counterpart experience similar success,” Clare concludes. “The aesthetic versatility of the Rio range and its ease-of-manufacture have helped facilitate this rise, and we’re confident that both the window and door frame will be similarly successful this year and beyond.”
