NEW! Envisage Flush Windows

Envisage flush windows are designed to replicate the timeless style of traditional timber-framed windows, whilst giving you the benefits of modern technology and design.

Our Envisage flush windows are manufactured so that the opening lights are not proud of the window frame, creating simple lines that are inspired by traditional design. Available in a range of both contemporary and period colours, and realistic timber grain finishes there’s something to suit every home. Our Envisage windows also come with a choice of modern and traditional hardware, allowing you to design the finish that perfectly complements the style of your home. For more information on our flush windows, don’t hesitate to contact our team or visit your nearest showroom.



We’ve specialised in windows for years, so we know what we’re talking about...

It could be down to one sole factor, or there may be a number of reasons behind your decision to come to Coastline for new windows. Once we know why you want to see the back of your existing windows, we will be able to suggest the most suitable window replacements. There is no chance of Coastline not having an appropriate set of windows as we have a massively extensive window collection.

Functionality – Until you see our full window range, you may not have realised that so many window styles existed. Give them all a try to discover that we have window offerings you open from the side or top, vertically slide and tilt & turn. The best place to do that is in our stylish showroom where we have our windows elegantly displayed. Once you find a window functionality you like, Coastline will guide you through the next steps.

Guarantee - The length of our window guarantee should be enough to persuade you to part with your hard-earned cash and trust Coastline. It runs for 10 years, which is the minimum expected lifespan of all of our window replacements. We reserve the use of top-class materials and components for our window designs, so that’s why we’re so confident in their ability to last for so long.
