Synseal’s popular Evolve VS sliding sash has been improved with the addition of a new deep bottom rail design option, to provide an even greater degree of authenticity for heritage and conservation project applications.
Standard Evolve vertical sliding sash windows feature a slimline bottom rail 60mm in height to maximise glass area and daylight, however a 100mm deep bottom rail has previously been available as a special manufacturing option by combining two extrusions. Now a new ovolo deep bottom rail created from a single extrusion, 100mm deep, is readily available to cater for projects that require authentic timber-mimicking PVC-U sliding sash windows, with the added benefit of improved visual aesthetic appeal.
“Investment in a PVC-U extrusion tool to create a new VS deep bottom rail ovolo profile was an easy decision to make,” comments Steve Brown, Synseal’s Products & Customer Service Director. “Visual authenticity is a key factor in today’s marketplace. The improved bottom rail complements other finely engineered aesthetic details such as our run-through sash horns and when considered in conjunction with the many practical material advantages of PVC-U, our Evolve VS heritage offering is a compelling specification.”
