NEW! Envisage Flush Windows

The Envisage flush casement is designed along simple lines, intended to replicate the earliest glazed timber windows from centuries past.

Characterised by a simple clarity of design and geometry, the casement’s opening lights do not sit proud of the outer frame. Envisage Windows brings the traditional timbered style of the late middle ages in line with rigour of the 21st century, offering exceptional security, performance and insulation. Because it maintains the original proportions used by carpenters for hundreds of years, the flush casement can be easily adapted to accommodate a wide variety of period and contemporary hardware or colours, which means that it can give you the finish that suits you best. An adaptable design means casement windows will suit any home, whether it’s a new build, or a heritage property.



Get the right windows for your home...

Everyone has their own personal reasons for wanting to replace old windows and doors and they should be clear in your mind when shopping for a suitable substitute. Perhaps you want to lower the cost of your fuel bills, or it could be because they no longer offer the aesthetically-pleasing looks they once possessed. Whatever your thinking, a James Oliver design consultant is there to guide you through the buying process.

Functionality - Far from being one-dimensional, our window range encompasses designs that function in a vastly contrasting fashion; some open from the side or top, some vertically slide, and some tilt & turn. When you see each of them in operation it may take you some contemplating to decide which best complements your lifestyle and property type. Our design consultants are always there to give you assistance should you need help deciding which works best.

Guarantee - Our comprehensive 10 Year Guarantee offers you complete value for money and, crucially, a lifetime of reassurance. We’re able to offer such a guarantee because our Envisage Windows are designed and manufactured to remain perfectly functional and completely fit for purpose for at least 10 years. Materials and components have been selected for their inherent durability and our manufacturing processes are second to none.
