Unrivalled Thermal Efficiency

Our flush sash windows have a minimal design that helps light enter a property. This will create the illusion of more space, no matter how modest the space is. Slim sightlines allow for unobstructed views of the outside and a sleek and elegant design that is suitable for all properties. Sitting flush against the frame, these windows looks neat and tidy and offers thermal efficiency.

By installing the flush casement windows we supply, especially when replacing authentic timber profiles, you will notice an immediate improvement on the thermal efficiency of the building. Whether you opt for double or triple glazing, our flush casement windows will help achieve low U-values.

Superior weather sealing and draught proofing performance, conforming to the exacting standards of the BS36751 accreditation, will stop a cold draught entering the building. This will make homes much warmer during the cold winter months as less heat will be able to escape through the glazing.

Our flush sash windows are manufactured to the highest possible quality using the best materials on the market and are put through stringent testing before being supplied to homeowners and tradesmen. When choosing Advance Building Plastics, you are guaranteed to receive the best quality windows on the market, at a competitive price.

Should any issues occur with your flush casement windows, or you have older profiles that require replacing, we can help. We offer both double and triple glazing window options for tradesmen and homeowners.

The multi chamber profile allows for reinforced flush casement windows. Recycled thermal inserts, made from aluminium or steel can also be used. You also have to option to add multipoint locks across the frame for a boost in security levels. Additional dog bolts improve stability around the entire frame and any intruders attempting to enter by attacking the hinge side of the window.
