Choosing the Right Timber Casement Window

Choose from lipped or flush casement styles with both top and side hung openers.

Lipped Casement Windows

The lipped casement window (also known as “storm-proof”) is one of the most popular styles of window in the UK. Our lipped casements feature a decorative edge on the opening sash, softening its appearance and making it suitable not only for modern properties but traditional homes too. 

Flush Casement Windows

This traditional style of timber window is ideal for both new build homes and renovations with its styling that is reminiscent of our English and Scottish heritage. Our flush casement windows feature slim frame sections, external putty line mouldings and ovolo or lambs tongue internal mouldings.

Safety (& security) first

Our timber casement windows come with modern easy clean or egress friction hinges, secure night vents and child safety restrictors.

Internally glazed as standard they also come fitted with high-security multipoint espagnolette locking handles and are Secured by Design & Part Q certified.

Totally bespoke

Totally bespoke sizes and designs of up to 5 metres and 5 lights wide using any combination of fixed and opening sashes in your choice of contemporary, traditional or heritage mouldings.

Create an oriel or bay feature window or go all out with curved frames or swept heads (curved plates).

Choice of Glazing

Choose from single, slimline, acoustic, double glazing or triple glazing. Create traditional styles such as horizontal, cottage, Georgian, or marginal bar using our applied 16mm, 25mm and 35mm glazing bars.

Divide panes with arched or gothic bars designs. Make a statement using lead in traditional designs such as diamond, square and Queen Anne style.

Overlooking a neighbour? Our obscure, translucent coloured and opaque painted glass makes for a great feature.

High Performance

Enjoy the sound of silence and sleep well at night with noise reduction up to 42dB.

Double glazing with warm edge spacers offer Uw values that are 40% better than current Part L Building Regulations.

Our casements are part of BlueSky high-performance window scheme and offer exceptional draught-proofing and weather performance.

Add a splash of colour

Every casement 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.

Casement FAQ's

Our most popular timber casement windows are the flush casement. 

On  flush casement windows the sashes are flush with the frame externally. On a lipped or storm-proof casement window the sash overlaps the frame.  

At Bereco our timber flush casement windows feature double weather seals that offer excellent weather performance and keep out the draughts. In addition, both our window styles come with the ability to adjust and increase compression on the weather seals.  

All of our casement windows are fitted with easy clean friction hinges. 

Bereco casement windows feature easy clean or egress friction hinges; when open the friction of the hinge holds the window in place. Our traditional lipped and flush casements also come with secure night vent position. 

Yes, we can offer these in both side hung or top hung (regency casement) designs, as well as  Tilt & Turn (opening in) window styles.   

Currently, Part Q is only applied to new dwellings, so if you are building a new home or converting a non-dwelling (e.g. a barn) into a home then it is a required. If you are renovating a home then it is not a requirement, however, we would certainly recommend that you look for a manufacturer who builds security in as standard as we do. Look for espagnolette locking and 3* high-security cylinders (neighbourhood watch approved) where possible.
