Energy Efficient UPVC Doors

Since its introduction, UPVC has quickly grown into the most sought after material for doors. Strong, durable and practically maintenance-free, UPVC doors continue to be popular with homeowners in Lanarkshire. Never fading, rotting or requiring repainting, your UPVC doors will look brand new for many years to come, and require no more maintenance than a simple wipe of a cloth to look brand new again. Doors play many important roles, but none more so than that of your home’s security. A strong, well designed door will keep your home safe; giving you important peace-of-mind for years to come.

At Crystal Clear Windows we take this very seriously, and that is why we use only the very best, strongest materials in the construction of all our doors. Featuring toughened frames and strong, multi-locking systems that provide exceptional security, UPVC doors also boast incredible external noise reduction and energy efficiency. Surpassing the insulation properties of both wood and aluminium, UPVC is non-conductive; meaning your doors will not transfer heat out or cold in, and thereby allowing you to keep your home warmer for longer for less.

No door can be considered complete without a letterbox, locking system, hinges and handles. They all need to look as good as the door itself, otherwise they can bring down its entire appearance and it’s of course massively important that they function successfully to ensure optimum door performance. Our hardware range embraces every single element of hardware, with a huge selection of colours available to match them to the chosen frame.


Energy Efficiency

A UPVC door will eliminate any heat loss and cold spots; helping to drive down the cost of energy bills as well as reducing your carbon footprint. The energy efficiency provided by the panelling, door frame and glass units contained within the design will help make your home a more comfortable place to live; regardless of the weather outside.


All of our UPVC Doors feature market-leading components and are created using the very latest technologies. This creates a door that will significantly improve the security of your home and help ensure your family stay safe.

All your favourite colours, inside and out…


Colours such as Golden Oak, Rosewood and White never seem to go out of fashion, which is why they feature on our UPVC front and back door panels. An even broader colour range is available if you opt for a door that is predominantly glazed and does not contain any panelling. Further character can be added to your door thanks to our range of textured and patterned glass designs, as well as a variety of sophisticated hardware solutions.

Textured Glass

Whilst there’s nothing wrong with plain glass, we understand that some people want a little more extravagance. This can be achieved thanks to our range of patterned designs for your front or back door. These charming doors are also very practical as they provide you with extra privacy. Patterns available include classic designs such as Autumn Leaf and Sycamore, as well as contemporary styles such as Digital and Cotswold.
