Add a splash of colour
Every sliding sash window is beautifully factory finished using the most environmentally friendly water-based paint or stain. Choose from any RAL Classic, RAL Design, NCS and BS colour charts or match to Farrow & Ball, Earthborn or Fired Earth colour collections.
With single or dual colour options you can create the perfect match to the exterior facade and interior decor of the property.
We offer both sliding sash look alike (side hung casement) and regency casement (top hung casement) mock sash designs in our range of contemporary lipped casement windows.
This style of windows is ideal when the sash window look is desired but impractical when working with narrow reveals and where you must comply with escape regulations but a traditional sash window doesn’t offer the clear opening needed.
Handles & locks
Our timber sash windows come fitted with fitch fasteners, hook lifts and opening restrictors. Choose from 2 designs of fitch fasteners, The Fitch Lock or the Brighton Fastener; 3 designs of opening restrictor the key-operated Vent Lock, the push and twist Vent Lock or the Angel Vent Lock. Our cords and weights windows also come with round end pulley wheels and optional D handles and ring lifts.

Sliding Sash Windows FAQ's
At Bereco we don’t offer a tilt facility; this style of window usually comes with unsightly and non-compressing brush seals that can affect weather performance. However, our cords & weights option is available with an easy clean system that allows the bottom sash to open inwards side hung.
