Envisage Flush Casement Windows

These windows are constructed to deliver an outstanding level of style and versatility, which makes a difference to all homes and buildings through a perfectly tailored finish. Constructed to imitate the original glazed timber windows, the elegance of the flush casement is evident in the simple lines. The opening lights are not positioned above the surface, imitating the version that would have been built by a carpenter hundreds of years ago. By preserving the true proportions, the flush casement flatters a variety of period and contemporary colours and hardware. When combined, this provides windows with a finish that complements your home, whatever its style.

By bringing together a traditional timber look with incomparable safety, performance and insulating features, these windows set themselves apart in the world of flush casement windows. Versatile styling is on offer that can complement any home, whether a simple contemporary construction, a heritage-style new build, or a traditional property looking for a great, modern means of insulation. Our flush casement windows guarantee you remarkable UPVC frames as a given with outstanding calibre, resilience and easy-to-maintain characteristics.

Your safety is imperative to us, so we will continually incorporate the utmost advanced multipoint locking systems. Sky-high heating bills and cold draughts are something we all dislike, but excellent insulation is guaranteed, thanks to clever designs and high-specification double glazing which ensure heat retention.

Shades and textures

Graceful, understated and genuine UPVC duplicates the grain of different timbers and discards the common flat white image. This includes period shades and two-fold coloured selections that work with any exterior and interior.

‘Secure It’ locking system for unconditional safety.

Our ‘Secure it’ window locking system is definitive in establishing security for your home and family. These windows proudly boast the police-guaranteed ‘Secured by Design’ stamp of approval. With a lock that connects along the full span of your window, its strength is impassable and has been tested over 30,000 times to ensure it is completely fail-safe. It therefore undoubtedly surpasses the industry demands of PAS34. Envisage windows are something you can feel safe and confident in, thanks to the ultimate protection they provide from the risk of break-ins.

Finishing excellence

Excellence goes beyond purpose. Although the final product must demonstrate that every element works seamlessly, including the hinges and handles, what makes a window a cut above the rest is the hardware. Appearance has the ability to balance the window in a way that can reframe and complement the whole house, giving you the style and finish you desire.


A modern home may choose to mirror its style through hardware with perfect lines and simplicity, whereas a traditional home may desire greater features. In any case, you will be looking for a window which is easy to use, long-lasting and well-matched to your way of living. Which is why we have developed a range of colours to complement your frame or door shades, if your mind holds a stylish vision, it is easy to achieve with our strong materials and class finishes.

What makes your windows distinct is the inclusion of all the attractive, enhancing details, features and finishing touches

Astragal Bars

Envisage windows encompass a comprehensive variety of accessories which are established to fit effortlessly as a way of completing our windows. For example, arched-head inserts can smooth the lines of your windows. Astragal bars fashion the magic and feel of a small paned window minus all the awkwardness of redecorating around the detailed window beads. Trickle vents are optional for protected night-time ventilation. A drastic alteration can be made to a window through a single astragal bar or indeed deliver a fascinating inflection to a larger plane of glass. Finally, there’s a variety of cills to finish any installation flawlessly.

Boundless colour selections to complement every type of home.

Unfortunately, we haven’t yet got every colour under the sun, but we can guarantee you we have abundant shades, wood effects and textures to indulge in. This includes the choice of a diverse colour and finish for both inside and outdoors.

Energy Efficiency

A+ and A++ UPVC windows are our best performing windows in terms of insulation and energy efficiency, which in turn makes them an environmentally friendly option when replacing existing windows. Thanks to ongoing innovation and product development A+ and A++ windows have overtaken A-rated as the best available on the market and the insulation offered by these types of windows is better than ever before. Quite simply, less heat is allowed to escape from your home, and more natural warmth from the sun is allowed into your home thanks to an intelligent composition of glass which delivers this twofold benefit and reduce your household carbon footprint.


We understand that the security of you and your family is a major consideration when deciding about home improvements, whether that be windows, doors, porches, conservatories or orangeries. That is why we invest in the latest technology and manufacturing to ensure all products meet maximum security requirements. Thieves and burglars target properties with poor quality framework or locking systems. You and your family can rest assured that you house won’t be targeted for that reason!

Noise Reduction

For new home improvements such as windows , consideration also has to be made for how well it presents noises from the outside world from entering your home. This is particularly important for properties in built-up areas, but also affects people living close to busy roads. All products from Visual are built with noise reduction in mind, tested repeatedly and constantly improved to ensure you have the most enjoyable living areas you could wish for that aren’t affected by the outside world.
