Smooth run-through sash horns with no revealing cap lines or wraparounds
Recreate the authentic timber look with a deeper cill option available
Sliding sash windows were a common sight in Georgian and Victorian homes and consist of a movable panel that allows you to easily control the ventilation in your home. Our sliding sash windows allow you to retain the original character of your home while improving its performance. They offer a simple operation with the use of tensioned balances. Either sash can also be tilted inwards to allow for easier cleaning. Spring balances are concealed within the framework for easy adjustment and eliminating the need for cords. With traditional features such as an oval-shaped frame and classic sash horns, the authenticity is retained, and they can be approved for use in conservation areas.
Designed to redefine classic sash windows, custom designs include run-through sash horns, no horn and deep cill options.
Installing one of the most secure uPVC sash windows available, our sash window security features include innovative internal sash interlocks and optional laminated double glazing.
Our uPVC sliding sash windows offer a maintenance-free design that won't rot, crack, warp, or fade throughout its lifespan (unlike real timber).
As well as offering EcoMax Glass as standard, our sliding sash windows are created from 80% recycled manufacturing off cuts.
