The Vertical Slider is an authentic looking sash window with Ovolo finishing that combines high performing modern materials and functionality with period character and design.

Much thought has gone into the Spectus Vertical Slider to ensure that the attractive style of a traditional sash window is retained, whilst providing all the benefits that modern technology can provide.

For ease and cost effective fabrication, each sash option is post co-extruded. Thermal properties are enhanced through the use of 24mm glazing as standard. Excellent weathering performance is increased with a pile seal detail on the sash edges and outer frame and air flow specification can be achieved through the use of trickle or glazed-in vents to suit particular applications as required.
