Flush Casement Windows

Envisage Flush Casement Windows are specially made to make your property stand out

Based on the first ever timber windows, their casement is distinguished by simple, clean-cut lines. The opening lights aren’t heightened on the frame, just as windows were made in the workshops of times gone by. Staying faithful to authentic sizing, the casement can be accentuated by various pieces of hardware and colours, allowing you to achieve a finish that suits the style of your home perfectly. Envisage Windows offer exceptional insulation, security, and performance, allowing you to combine the charming traditional timber look with the practical needs of the modern day.

Whether you have a rustic home or a minimalist newbuild, the adaptable design of our windows will guarantee a look that works for you.


By choosing Envisage flush casement windows, you’ll receive a product with industry-grade quality, reliable durability, along with the convenient benefits of our high-quality UPVC frames with every order.

We understand how important the security of your home is to you. That’s why we use the most dependable multipoint locking systems on our windows. Likewise, we know how important energy efficiency is to any responsible homeowner, which is why we apply cutting-edge designs and high-grade double glazing to provide both comfort, and peace of mind for when you come to open your energy bill. The rest? Well, that’s down to your personal preference.

Lines and sizes – Either go for something clean-cut and minimal, or add an interesting frill to your windows using astragal bars. We manufacture our flush casement windows to ensure perfect proportions, and an understated, yet elegant style.

Stays and handles – When it comes to features like windows, the smallest of details can have a huge impact on the overall effect. We offer a wide range of both classic and modern stays and handles, ensuring the details of your windows always suit the style of your home.

Textures and shades – While our frames are UPVC, they’re a world away from the standard white material you may be thinking of. Their finishes are expertly made to replicate the shades and textures of various timbers, allowing you to create a warm, homely feel. Our dual-coloured and period shades work beautifully with lime-wash, brick, stone, and many other materials.
