Impressive insulation with smooth sliding functionality

Unlike the traditional timber vertical sliders of old, Spectus uPVC vertical sliders make use of multi-chambered internal chambers and pile sash seals to keep properties weathertight and efficient. This results in ‘A’ rated windows which when combined with 24mm double glazed units forever prevents heat leaks and stamp out pesky draughts and cold spots.

Installers take comfort in knowing that this emphasis on insulation doesn’t compromise the easy-to-use operation of all Spectus uPVC vertical sliders. Smooth operating balance mechanisms ensure a smooth glide every time, and inwards tilting sashes act as a convenient extra that makes cleaning just as easy as sliding for end users.

Customisation elements that combine to create the ultimate traditional style

We supply Spectus uPVC vertical sliders to be somewhat of a blank canvas in terms of authenticity, making the system wholly configurable to let you meet any homeowner’s specific tastes. Optional astragal bars, sash horns, weather bars, and deep bottom rails all blend to specifically provide a period look, while flush gaskets mimic traditional glazing.
