Windows and doors are not our only forte. At Cladwinds Ltd we can help you with your larger double glazing projects and offer a range of conservatories and extensions. Thanks to a variety of styles and designs, these spaces can be built to fulfil your needs.

We use Computer Aided Design (CAD) during the installation process, which helps us to perfectly plan the layout you want. We offer our conservatories in several finishes, such as Irish Oak, Wood Grain, and Light Oak to name a few. Each conservatory is safe and secure, due to being fitted with high-tech locking mechanisms. The double glazing also offers thermal efficiency, with less heat escaping from your property and natural light heating it, meaning you should save some money on your energy bills.

Security and thermal efficiency are just some of the benefits our range of conservatories provide. They also require very low maintenance. We use Pilkington Activ™ Self-Cleaning Glass on all our conservatories, which breaks down organic dirt using daylight and washes it dirt away with the rain.

Our range of conservatories include:

Conservatory Roofs

If you’re looking for the perfect upgrade to your conservatory or the final piece to an unfinished project, then why not consider one of our conservatory roofs. At Cladwinds Ltd, we work with two excellent conservatory roofs that will compliment your existing double glazing.

The Supalite Tiled Roof has an incredible u-value of 0.18 and is designed so you can use your conservatory year-round. The lightweight aluminium frame allows for an easy fit to an existing frame or for the addition of new windows and doors. You will also maximise daylight thanks to the large vents in the roof.

The Guardian Warm Roof™ is an energy efficient insulted conservatory roof. The efficiency has been approved by the Local Authority Building Control (LABC) and leads the market for its thermal retention. There is a good range of both external and internal finishes for this type of room, and a selection of roof tiles from Tapco Slate and Metrolite.
