Ideal for conservation areas

Our Heritage profile Flush casement windows are specifically designed for Conservation areas and listed buildings*, with options for both single glazing and slimline double glazing.

Our 14mm slimline double glazing units are internally glazed and utilise a full drainage and ventilation system. They can achieve a centre pane U Value as low as 1.2, and are fully compliant with building regulations, meaning you get all the benefits of modern window design whilst still satisfying conservation requirements.

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.

Handles that match

Obscure glazing

Glazing is an important design element for any project and can make all the difference when creating a feature window or door. A variety of obscure glazing patterns are available with different designs offering varying privacy levels (rated 1-5 with 5 being the highest level).

Redwood or hardwood timber

All our products are manufactured using FSC100% engineered laminated timber. We offer both redwood (Scots Pine) and hardwood (Dark Red Meranti) – both with the same extensive warranty. When comparing the two, our hardwood has a more of an open grain structure meaning it gives more of a textured finish, particularly when stained.

Casement Window FAQ's

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.
