We at Atonic Double Glazing offer an extensive range of upvc windows, doors and conservatories. When planning your home improvement project you can choose replacement windows from modern pvc styles through to more traditional styled types with Georgian and leaded (or stained glass) panels. Choose attractive exterior doors, French doors or stylish patio doors - all available with high performance double glazing with sound insulation and heat enhancing benefits. Our range of conservatories is superb - check out the examples on this website. Not only are these products attractive, we also provide the latest multi-point locks for increased security.

We only use advanced upvc products and the best in modern materials and technology. When we meet you'll also notice we don't use any of the high-pressure sales techniques you may well see some of our competitors use, we don't believe in closing techniques or refuse to leave your home until you place an order! We support all our products with a comprehensive guarantee.

Certass which stands for certification and self assessment, was formed several years ago and was one of the original Quality Mark certification bodies. It is therefore a natural progression for Certass to move into the self assessment market.The Statutory Instrument for Certass approval was made on 9th March 2006 and was laid before Parliament on 15th March 2006. The approval came into force on 6th April 2006 and has now been published by HMSO as Statutory Instrument 2006 No. 652.

In simple terms this means that Certass can invite glazing applications to be licensed for Self Certification, therefore our application forms are available on request.

So if your home improvement project includes the installation of replacement windows, exterior doors, a porch or add a conservatory, you can be sure that we will be your best choice for optimal performance, style and quality. We are confident that it will not cost as much as you may think - why not get an online estimate while you're here?
