Stand out from the crowd with beautifully designed Flush Casement Windows available in UPVC or Aluminium

This beautiful new design gives the exterior a flush appearance, so it sits flush with the face of the window, rather than standing proud. Quality craftsmanship never goes out of style. Centuries ago, the original glazed timber windows were made by hand in a master carpenter’s workshop. Clean lines defined their design and our flush casement windows honour that tradition and history, with period styling, while offering a 21st century update with the option of modern colours and hardware. Whatever your home’s style, you can create the perfect finish to complement it.

Oak UPVC Flush Windows


Flush casement windows are a true declaration of style. Our window frames are perfect for a clean, modern appearance, but are also built with the strength to withstand even the harshest of weather conditions. Whether you choose from our flush UPVC window or flush aluminium window collection you’re guaranteed the same high quality finish from Hazlemere.

Grey UPVC Flush Windows


Flush UPVC windows are different. That’s because you can expect top-of-the-line insulation, security, and performance as standard. Get your dream, authentic timber-look while meeting the demands of modern life. Every home can benefit from their versatile design. Proud old dwellings with legacy, picturesque new family houses, or sleek, cosmopolitan architecture all look wonderful with UPVC flush casement windows.

Aluminium Flush Windows


Everything you’ve come to expect from our contemporary aluminium range, but with a classic, stripped back appeal for a more refined taste. Without any of the perceived ‘bulk’ of a standard casement, our aluminium flush window sits flush against the frame inside and out for a muted, graceful appearance in keeping with traditional design from centuries past.

Comfort and relaxation with the 'Secure It' locking system...

You need to be confident that your home is secure and your family protected, that’s where our ‘Secure It’ locking system for windows comes in. The whole length of your window is secured by the lock, not just one central point, for ultimate strength. The robustness of our locking systems has been tested over 30,000 times so you know they’ll stand up to the test. Our ‘Secured By Design’ standard is police-approved and performs over and above the industry demands of PAS24, so you are fully assured that your Envisage windows will offer the protection you and your family deserve, making your home a sanctuary of shelter and safety from the outside.

We say ‘small details’ but the colour, glazing and hardware you choose for a Flush Window is actually really important and brings together the entire design. Consider the many options carefully before making a final decision.

Every home will find an ideal match in our incredible selection of colours...

We have a vast range of colours for you to choose from with various textures and reproduction wood grain also available. And don’t worry if the inside and outside of your home have separate needs, you can choose a different finish and colour for each. It doesn’t matter what your dream style is, whether you want to make a bold statement or complement historical architecture, we know we have an option that will thrill and delight you, and your home.

A colourful array of stylish finishes...

You will be stunned by how astonishingly good our aluminium colours look. A robust powder-coating process is what gives them that all-important durability and richness in texture so that when applied to the frame they truly sparkle. The beauty of RAL aluminium coloured windows is that they can be dual coloured and usually come in a choice of gloss, matt or satin finish.

Choose from over 150 colours or from our popular colours shown.

Privacy glass...

Perfect for the bathroom or windows which are overlooked, our privacy glass options obscure the view into your home without compromising light. Privacy glass options are available on both our double and triple glazed units.

Practical hardware solutions to simplify usage...

We stock minimalist hardware with great lines to complement a modern house, and more detailed, antiquated styles for more classical properties.
