We care about quality.

Whatever shape and size you want them, windows connect you to the outside world, keeping you warm and dry, and insulating you from wind, rain, hail and snow, as well as noise, pollution and potential intruders.

But Lemon Glass windows go beyond ordinary, functional windows, giving your home or office a look and feel of quality and prestige. And the quality of Lemon Glass windows is entirely down to the time, effort, energy and craftsmanship that goes into creating them.

Lemon Glass has spent many years seeking out and vetting some of Europe’s finest manufacturers, and we insist on a level of quality in the materials and workmanship that few could match.

Who are they for?

Lemon Glass windows are for anyone who wants their property to look good and last longer. Using quality materials adds value to your property, and will extend its life, giving you real value for money.

Typically, Lemon Glass clients include home owners looking to renovate or extend their property, builders looking for high-quality products for extensions and new builds and property developers who value superior products to add prestige and value to their new build projects.

We also work closely with architects who regularly specify Lemon Glass windows in their plans for residential houses, flats and apartments and high-end commercial premises.

You choose the style.

We offer three distinctive types of window products

  • Casement windows
  • Sliding sash windows
  • Pivot windows and tilt & turn windows

Whichever style you want, they are available with traditional and modern options,
and a range of accessories to suit.
