    Totally bespoke flush timber casement windows for homes in Yorkshire

    We offer totally bespoke sizes and designs for our wooden flush casement windows so that we can accommodate any home within Yorkshire. We offer sizes spanning five metres and five lights wide, and we can use any combination of fixed and opening sashes which are available in traditional or heritage mouldings.

    You can even create an oriel or bay feature window for your living spaces, or to make your home really stand out why not opt for curved frames or swept heads (curved plates)?

    To replicate the heritage commonly found within Yorkshire architecture, adopt traditional styles such as horizontal cottage, Georgian, or marginal bar using our applied 16mm, 25mm and 35mm glazing bars. Alternatively, make a statement using lead in traditional designs such as diamond, square and Queen Anne style.

    Redwood or hardwood timber windows

    All our products are manufactured using FSC® 100% 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.

    Wooden Flush Casement Window FAQ's

    What is the difference between flush and lipped 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.

    Is there a difference in weather performance between lipped and flush casements?

    At Bereco, our flush casement timber 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 which is perfect for tackling the unpredictable weather within Yorkshire.

    What hinges do your casement windows come with?

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

    Do I need a stay on my casement windows to hold them open?

    Our Bereco casement windows feature easy clean or egress friction hinges which means, when open, the friction of the hinge holds the window in place. Our traditional lipped and flush casements also come with secure night vent positions helping to keep your home well protected in the evenings.

    Do you offer mock sash casement windows?

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

    Do I require Part Q on a casement window?

    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 as standard, like we do. Look for espagnolette locking and 3* high-security cylinders (neighbourhood watch approved) where possible.
