Envisage Flush Casement Windows

Your chance to make a design statement

These flush casement windows are designed to mimic the traditional style of some of the first glazed timber windows. The design is simple and elegant with minimal lines, to fully reflect the style of centuries past. The windows are all designed to keep to authentic proportions but can be individually styled using a range of both modern and traditional hardware and colour options. The windows have been designed to stand out from the crowd, not just in aesthetics but also in security and insulation. This is your chance to bring a traditional style to your home with the modern comforts we expect today.

These windows are completely flexible and can be tailored to suit any property from a modern new build development to a rustic, heritage property. Envisage flush casement windows are both durable and easy to care for thanks to the superior quality UPVC frames.

We understand that when choosing which windows to fit in your home, security is one of your key concerns. All windows will be fitted with the most advanced multipoint locking systems as standard. Alongside securing your home, it is important to choose windows which provide great insulation. These windows use innovative designs and high performance double glazing to give you optimum warmth during the colder months.

Line and proportions

It is important that your windows match your home’s style and we include a variety of line options. The design of these windows allows you to choose simple glazing or astragal bars for a more intricate finish.

Handles and stays

To finish your windows perfectly, it is important that you can select the ideal hardware to complete your vision. We have a range of carefully designed, traditional and contemporary fixtures and fittings which all seamlessly fit these windows.

Shades and textures

Not everyone wants plain white UPVC frames, which is why we have created a pallet of authentic shades to mimic different timbers and period tones. It is also possible to have a dual finish, allowing you to match your windows to your interior decor.

‘Secure It’ locking system for complete home security.

Envisage Flush Casement Windows are fitted with our innovative ‘Secure It’ window locking system. For your peace of mind, the lock is fitted along the length of the window to ensure it is completely unbreakable. To put your mind at rest the locks are tested over 30,000 times and surpass all industry demands such as the PAS25 regulation. They are even approved by the police under their ‘Secured by Design’ standard. Security is important to everyone, and these windows will ensure you and your family can rest easy day and night.

Carefully designed finishing touches to complete your look

We know that it isn’t just the functioning and the security which makes you choose your windows, it is the overall design. Appearance is one of the first things which draws our customers to this range. The key is in the flexibility we provide, from simple hardware for modern homes, to intricate lines for a traditional style. Not only do our hardware options look great, they are very durable and easy to use. The colour choice is completely up to you, whether you want a timber effect to blend in or a bold colour to mimic your front door.

Personal touches to suit your lifestyle

All of the accessories in the Envisage range have been created with usability and design in mind. Whatever your individual style, these fixtures will complement the design of our casement windows. If you prefer a more traditional look, the astragal bars or arched head inserts will add an elegant finish. On the other hand, if you are looking for a contemporary finish, a single astragal bar can be very stylish when combined with our range of cills. When it comes to functionality, it is possible to add trickle vents to allow increased ventilation during the night.

A variety of colours to match your home perfectly

Whatever style you are looking for, we have a range of perfectly designed colours and wood effects. The finishes have all been created by our expert design team to match both the outside of your home and the interior. Whether you would like the windows to have a natural wood effect or a heritage colour, the choice is entirely up to you. It is even possible to choose a dual finish, many people choose a wood effect for the outside and a neutral colour shade for the inside.

Innovative glass to save on your fuel bills

We increasingly invest in the latest technologies to improve the quality and functioning of our glass panes. These panes have been covered with an almost invisible coating, which will help keep your home warmer during the cold weather. The panes feature U-values as low as 1.2W/m2K. The sealed units are fitted with warm-edge spaces and inert gases to create a thermal barrier between the cold temperatures outside and your cosy home. If you take a little time to research your glass options, it can save you plenty in the long run.
