Welcome To GLS Windows

Double Glazing, Windows, Birmingham, Leicester & more

At GLS Windows we have a strict work ethic. Whatever type of work we undertake, whether it is the manufacture and installation of Windows and Doors, the replacement of Fascias, Soffits and Guttering, the manufacture of trade supply items, or the design, manufacture and installation of a Conservatory, Orangery or other double glazing products, we make a firm promise to all of our customers - that we will operate with "Pride in Our Workmanship". Through years of experience, our team has discovered that this practice leads to customer satisfaction, which in turn leads to new customers and the return of satisfied customers. If we can stand back and look at an installation and say "we are happy with what we have done" then we know our customers will also be happy.

All of our Windows, Doors and Conservatories are manufactured in-house at our premises in Cosby by a team with over 40 years’ experience in the trade. Using the Swish 24/7 70mm Profile System, we can produce what we believe is the most aesthetically pleasing and most energy efficient product in today’s market. All of our installations are carried out by our own fitting teams and, as we are affiliated with Fensa and the GGFi, the quality of every installation is certified to provide our customers with protection and peace of mind.

We offer a wide range of products that include Domestic and Commercial Windows and Doors, Conservatories and Orangeries, Bi-Folding Doors, Vertical Sliding Sash-style Windows, Tilt and Turn Windows, Composite Doors & many other Double Glazing products to Birmingham, Leicester and across the Midlands.

We use the latest in energy saving technologies, which include Low-E and Low Iron Glass, Warmedge Spacer Bars, RCM (recycled composite material) Reinforcement and the use of Argon and other gases.

We are now proud to be able to produce and install our most energy efficient Window to date, the GLS Eco-Save A Window, which is a BFRC certified A-Rated product that can help to reduce household energy bills. We provide free, friendly and impartial quotations, with our potential customers being visited at their homes by a company representative who does not operate on a commission-based salary. This ensures that we do not use the hard sell techniques that unfortunately are associated with larger national companies, but does enable us to provide our customers with products that are equivalent or, as in the majority of cases, superior to that provided by the larger national outfits at a lower cost.

For a Free Quotation please call us on 01455 202985 (daytime) or 07753 748769 (evenings and weekends) or click here to contact us using our simple contact form.
