Replacement Windows in Kingston | Double Glazing Specialists

Did you know that uPVC windows are entirely weatherproof because dampness cannot penetrate the surface of the material? Also, uPVC is non-corrosive so it will neither rot nor rust. Better still, uPVC replacement windows are energy-efficient and require little or no maintenance. This makes uPVC windows a perfect choice for many of our customers in the Kingston area. Generation Windows operates out of a dedicated showroom in Sutton.

Our showroom has an additional range of doors and conservatories on display.

We combine uPVC frames with double glazing to create replacement windows, doors and conservatories with exceptional thermal and sound insulation. With double glazing, the air between the panes creates a vacuum to prevent cold air and draughts from entering your Kingston home, and to stop warm air from escaping during the autumn and winter months.

The energy-saving qualities of double glazing make our own uPVC replacement windows the most efficient products in our market when compared to other materials. Did you know that uPVC windows could save as much as £120 a year in utility costs? That’s a massive saving which could reach as much as £2,400 over the expected 20-year lifespan of the product.


In the same way as we see exceptional performance from replacement windows, uPVC and double glazing both work well with conservatories. However, uPVC conservatories don’t need to have the bright white finish that is now so popular with most uPVC windows. In fact, it is possible for our Kingston customers to choose from a full range of different colours on any conservatory – including brown, black, grey and green to name just a few.

One of the most popular finishes for conservatories is wood grain. This gives homeowners the attractive appearance of a real wooden conservatory without the associated expense of genuine timber, but with all of the benefits one might expect from premium quality uPVC. Generation Windows also supplies orangeries to homeowners in the Kingston area.

We see conservatories as a perfect way to add welcome living space to a home without the planning, the disruption and the expense associated with home extensions. Because we offer uPVC as a framework option on conservatories, Generation Windows can build them to match uPVC windows or, indeed, our replacement windows in aluminium or timber.
