After a few bright and sunny days last month, autumn has now landed here in Darlington! The winter coats are out, people are lunching on soups rather than salads and we’re all facing the same old question – is it cold enough to put the heating on?


So, what better time than now to check that your house is in order before winter sets in? With figures suggesting that up to 30% of heat loss in the home is down to draughts, it’s worth checking that your doors are in good repair.


Here at Nationwide Window Systems, we fit a wide range of PVCu and composite entrance doors across Darlington, Richmond and the North East. But for the ultimate in energy efficiency, you can’t beat a Solidor composite door. Stylish and secure, they’re the perfect option for anyone wanting to upgrade their home this winter.


Keeping warm

Made from multiple materials, Solidors boast excellent thermal properties. Their internal core contains wood and other insulating materials - which are protected against the elements by a weather resistant outer skin.


Staying safe

Security is never compromised at National Window Systems and you can choose from a wide range of multi-point locking systems. We can fit high standard cylinders, key-free systems and even the industry’s largest dead bolt if you require!


Choice of colours

Available in a range of 17 colours, with a variety of glazing units as well as frame and skin options there are over 10,400 colour combinations to choose from. At National Window Systems we’re experienced in working with all styles of properties and we can help you find the perfect option for you. Once you’ve chosen the colour, you’ll be glad to know that each door has a guaranteed UV stable colour fastness which means it won’t fade in the sun.


The little extras

A full range of Prolinea door hardware means that you can add the perfect finishing touch to your Solidor. From letterboxes, to door handles and knockers, Prolinea is made to the highest standard and of premium quality - ensuring your door will always look well dressed.


Easy to maintain

With highly durable plastic skins, you’ll never need to paint or varnish your new composite door and the guaranteed UV stable colour fastness will ensure that it looks as good as new for years to come!


Protecting the environment

Manufactured using 100% fully recycled door frame reinforcing, Solidors are fully recyclable. Our door skins are lead-free too, for environmental benefit.


Peace of mind

Our doors have achieved BSI ISO 9001, are BSI Kitemarked for enhanced security, PAS 23-24 and benefit from Secured by Design accreditation, whilst our glazing is manufactured to BSEN1279. With National Window System’s 12 year manufacturing guarantee also included you can be completely confident that your composite door has been manufactured to the highest of standards.
