Roseview Windows is claiming an industry first with a timber-style sash horn design that is says could not previously be achieved in uPVC.
The curved profile of the sash horn, dubbed Seahorse because of its shape, was made possible by investment in the CNC technology already in use on the fabricator’s Ultimate Rose sash window, as MD Mike Bygrave explained:
“A horn detail like this can’t go through a typical milling machine. It was made possible by the specialist CNC processes that we already use for our existing seamless run-through horns, and the different way of looking at product design these techniques open up.
“The hidden cap also provided a challenge because of the deep recesses that are fundamental to such a traditional horn design. Long-term temperature testing showed that traditional foiling techniques couldn’t handle the intricate design and deep recesses reliably. So we had to take a different approach to design and manufacture a textured cap that doesn’t rely on standard foiling.
“It may seem like a small detail but it makes a huge difference, and it’s another milestone in the development of timber-alternative sash windows. Pushing the boundaries of conservation-grade authenticity and leading the market for sash windows is what we do at Roseview; and this is yet another example.”
