At Prior Products, we offer only the best quality for your home. Our most recent addition to our fantastic variety of products on offer is the flush fit window.

Blending modern with traditional, the Rehau Rio Flush Fit window offers a sleek, flush finish that blends in beautifully with the exterior structure. Designed to mimic the look of a traditional timber window, but with all the benefits of uPVC, the flush fit window will combine seamlessly with any style of home and its surroundings.

Why choose flush fit windows?


With PAS 24 security accreditation, Rehau Rio Flush Fit windows have all the added benefits of high security locking mechanisms, ensuring that your home has the best protection available. Similarly, our windows meet the highest BSI weather performance ratings, ensuring that your home is not only protected from home invaders, but extreme weather too.

Low maintenance & Long-lasting

Where timber windows need annual maintenance to ensure they look good and work efficiently, uPVC windows are far more resistant to weather, corrosion, warping and rotting.

Thermally efficient

The Rio Flush Fit windows benefit from a high ‘A’ energy efficiency rating, helping you to save on your bills. The windows also help to prevent noise pollution, so you can sleep with less interruptions at night.


Not only are our windows highly secure, low maintenance and capable of saving you money, they are available in a variety of beautiful colours.
