Perfect for Period Homes and Heritage Projects

These vertical sliders are perfect for projects where the traditional sash look matters. Whether you’re working on a Victorian terrace or a cottage in a conservation area, they replicate timber without the high cost or ongoing upkeep.

The outer frame is 128mm deep to match the proportions of original timber sashes, making them easier to install into existing openings. The authentic look means they’re often accepted for use in conservation areas by local planning authorities.

Styles and Details to Match Any Property

Spectus vertical sliders are available with a range of optional features that add authenticity and help match original details. Georgian bars, sash horns, deep bottom rails, and flush gaskets give you the flexibility to create a genuine period appearance.

The frames and sashes feature a traditional ovolo shape, and colour options include heritage tones, woodgrain finishes, and dual colour choices.

Built for Modern Performance

Behind the classic appearance is a high-spec uPVC window built to perform. Thermal efficiency meets today’s standards thanks to 24mm glazing units and multi-chambered profiles.

Security is equally well considered, and because they’re made from uPVC, maintenance is minimal – with no painting, warping, or rotting to worry about down the line.
