About Us

AboutDoubleGlazing.co.uk is owned and run by Excelsior Information Systems Ltd, a UK based Internet publishing company established in 1991.

Our Mission is to create the best double glazing website in the UK.

If you’re thinking about buying double glazing, it makes sense to do some research on the Internet before you buy. Informed consumers make better decisions, and get better deals.

But once you start researching double glazing on the web, you’re likely to discover, as we did, that there are very few sites giving high quality information and independent advice on the subject.

Most sites belong to double glazing manufacturers and installers, or trade bodies with an agenda to promote one sector of the market – eg uPVC or wooden double glazing.

So we set out to create an independent source of information for the double glazing buyer – and AboutDoubleGlazing.co.uk is the result.

Because we are a publishing company rather than a double glazing company, we have no agenda, or bias, and we can give you an honest overview of the whole market, with no hidden agendas, and no strings attached.

We’ve spent many months, and invested thousands of pounds in commissioning extensive, original research into the UK Double Glazing market, to enable us to bring you detailed, independent information to help inform your buying decisions.

Before buying, it helps to know about how double glazing works, and the different features and types available, and the advantages and disadvantages of each. It would also help to understand U Values, and the impact of energy efficient glass. Is self-cleaning glass a worthwhile investment, or an expensive gimmick?

We’ll also inform you about everything from how to deal with pushy salesmen, whether you need planning permission, and what building regulations you need to comply with. We also have detailed articles about the financial aspects of buying double glazing, as well as your legal rights when something goes wrong.

So before you jump into the (sometimes shark-infested) waters of the UK Double Glazing market, prepare yourself by reading the articles on this site. Become an informed consumer, you’ll be well prepared to make the best choice, and to get the best deal on your Double Glazing.

We hope you enjoy AboutDoubleGlazing.co.uk, and find it useful. If you have any comments or suggestions, please don’t hesitate to contact us.
