Roseview Windows has launched a new feature that its representatives claim marks a significant step forward for timber-alternative window design. The new sash horn uses a design common to original timber sash windows but which previously couldn’t be achieved in PVC-U, we have been told.
The curved profile of Roseview’s sash horn, dubbed Seahorse because of its shape, was made possible thanks to the specialist sash window manufacturer’s investment in cutting-edge technology. Roseview staff had already put the technology to good use by producing the business’ award-winning Ultimate Rose sash window, but Mike Bygrave, Roseview’s director, explained why the new feature marks a step change, as well as the reasons behind the new product launch.
“At Roseview we’re constantly looking at ways that we can improve our class-leading sash windows, both in terms of aesthetics and performance,” Mike said. “By recreating an important detail often seen on period originals, Seahorse is another step on that journey towards making the perfect timber-alternative sash window.
“Like all the best features, Seahorse seems simple. But creating it was anything but. 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.
“The result, however, was well worth the time, effort and investment that went into creating it. 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.”
The new Seahorse sash horn is available immediately and is exclusive to Roseview’s Ultimate Rose sash window. For more information visit roseview.co.uk/seahorse or call 01234 712 657.
