Purposely designed to mimic the timeless styling of an authentic timber window, the Envisage range offers the cleanest of lines. This outstanding collection also promises opening lights that don’t stand proud of the frame.
Their authentic appearance is enhanced further by the application of a series of Heritage and modern finishes and hardware, giving you the opportunity to ensure the window design effortlessly matches your home’s character. Where Envisage Windows significantly differ from traditional timber windows is that they guarantee you modern window performance in terms of security and insulation.

The adaptability of the Envisage range means these outstanding windows will look just as at home on a period residence as they would on a new-build property.
If you reside in a contemporary residence, the likelihood is that you will want unfussy hardware with clean lines. Those living in a period home are more likely to be drawn towards more detailed hardware.


Explore our Envisage Flush Windows
While preserving the timeless aesthetic of a traditional flush window, Envisage surpasses old flush window designs where it truly matters – security and thermal efficiency. Far more advanced, Envisage sets a new benchmark for flush window performance, expertly crafted by Planet.
Flush Casement Windows
We take immense pride in reviving this universally admired window with our own unique touch. The Envisage design draws heavily on the historical principles that shaped classic flush windows, particularly the retention of their most striking feature – a perfectly flat exterior.
Where Envisage stands apart from traditional flush windows is in our decision not to use wood in its construction. The key benefit of this is that Envisage significantly outperforms its predecessor in terms of insulation.

Flush Tilt & Turn Windows
If you’re on the hunt for a practical window style, the Envisage flush tilt and turn window deserves your attention. Its clever opening mechanism has been specifically designed to make cleaning and ventilating your home easier than ever.
Crafted from UPVC, tilt and turn windows are a popular choice for families with young children thanks to their child-safe design. The ability to tilt the window slightly inward at the top allows for ventilation without compromising safety.

Flush Bay & Bow Windows
A bay or bow window setup welcomes abundant natural light into your home while adding a sense of extra depth to any room. Typically crafted from three or more rectangular, triangular, or polygonal shapes, this timeless style is a favourite for front lounges.
Upgrading your space with an Envisage bay or bow window will enhance the charm of your living environment and offer you a whole new outlook on the world outside.

Flush French Windows
The UPVC profile of our Envisage flush windows ensures lasting quality and minimal upkeep. Featuring a floating mullion and side-hinged sashes, they open up to offer an uninterrupted, expansive view.
The two fully openable sashes make it simple to invite the outdoors in, flooding your space with light and fresh air. For enhanced security and peace of mind, consider the addition of an espagnolette locking system. Envisage French windows deliver the striking refresh your home deserves.

Flush Cottage Windows
Much like the heritage windows that used to grace British homes, Envisage flush cottage windows exude timeless charm. However, they differ from traditional cottage windows with their internal and external flush opening vents, reminiscent of classic painted timber designs.
To further enhance their undeniable beauty, consider adding timber-effect foils – a feature that will elevate your home’s character and leave it looking more impressive than you ever thought possible.

Flush Shaped Windows
Flush arched and gable windows offer a tailored touch, showcasing a striking finish. Often the go-to choice for modern homes, both window styles effortlessly meet current UK thermal standards.
Gable windows, typically triangular in design, excel at capturing sunlight and flooding interiors with natural warmth. Whether you favour arched or gable, you can expect standout elegance paired with uncompromising practicality.

Flush Fixed Windows
If you’re willing to sacrifice window operation for a design that perfectly showcases a stunning outdoor landscape, Envisage fixed flush windows deserve a spot on your shortlist.
These fixed windows beautifully frame outdoor views, creating a picture-perfect focal point you won’t tire of admiring. Budget-friendly and highly customisable, they can also be crafted in extra-large sizes to maximise the impact.
