London, UK – 16/12/25 – Colin’s Sash Windows has released findings from a recent overseas installation in Jamaica, where its British-made Spectus uPVC sash windows were subjected to hurricane-force conditions during Hurricane Melissa.
The windows formed part of a bespoke window and door package supplied from the UK several years ago for a new residential build. Following the storm, post-event the homeowner confirmed that all uPVC sash windows remained fully intact, with no visible damage to frames or glazing.
In contrast, several accompanying uPVC French doors installed on the same property sustained storm damage as a result of extreme wind pressure and flying debris, highlighting the differing performance demands placed on window and door systems in severe weather environments.
“We’re proud that our sash windows stood firm in such challenging conditions,” said Colin Greenslade, founder of Colin’s Sash Windows. “They have been laboratory tested in up to 140mph winds but this provided a genuine real-world test of the Spectus system and demonstrated the strength of its design and fabrication.”
While the project was based overseas, the company says the results are equally relevant to UK homeowners, architects and specifiers, as resilience and durability become increasingly important considerations in window design amid changing global weather patterns.
Colin’s Sash Windows continues to supply and export bespoke window and door packages to international markets, applying lessons learned from real-world installations to improve long-term performance across its product range.
