Get in touchAll 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.

Find out moreOur flush casement windows are naturally renewable, carbon neutral and made from only sustainably sourced FSC® 100% certified softwood or hardwood. The care and attention we give to our timber before and during the manufacturing process ensures a 60 year+ life span, 10-year warranty and low maintenance for life.
SustainabilityOn 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.
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 as standard, like we do. Look for espagnolette locking and 3* high-security cylinders (neighbourhood watch approved) where possible.
Whether you’re a homeowner working on a renovation project for your home, an architect looking for specific windows and doors, or a trade professional building new homes and properties, we offer a tailored service to help you budget, design, and order bespoke timber windows and doors.
