Victorian Sliders® is proud to announce the launch of the new ECOSlide® Flagship Window, representing the next generation of our best-selling Elegant Sash Window. Developed by our in-house Innovation Team, the upgraded ECOSlide® sets a new benchmark for performance, durability, and weather resistance—offered as standard.
This major upgrade delivers performance levels that go well beyond typical requirements for residential windows, making it one of the most (if not the most) robust sash window systems available on the market today.
Tested to Withstand the Worst of British Weather
In the UK, the most severe weather events including extratropical cyclones and winter storms — can generate wind pressures equivalent to Class C3 or C4 ratings. The new ECOSlide® Flagship Window has been rigorously tested and certified to meet or exceed those standards:
- Air Permeability: 600 Pa – Class 4 (maximum achievable under EN 12207)
- Water Tightness: 300 Pa – Class 7A (suitable for exposed locations)
- Wind Resistance: 1600 Pa – Class C4 (withstands storm-force winds up to 115 mph)
These levels ensure that the ECOSlide® Flagship Window remains airtight, watertight, and structurally secure—even during the UK’s most extreme weather conditions.
Bringing Premium Performance to Every Home
“We’ve taken everything customers love about ECOSlide® and pushed it even further,” said Sue Davies, Head of Sales at Victorian Sliders®. “This isn’t just a cosmetic improvement—this is an upgrade in engineering, reliability, and real-world performance. And the best part? It comes as standard.”
Thanks to these advancements, the new ECOSlide® Flagship strengthens it’s position within the RMI market as well as for new build and government-backed housing projects, particularly those that require Secured by Design accreditation and premium product specifications.
