A Guardian roof will make all the difference

Lets face it…Having a conservatory is not much fun during the Winter months, it’s almost impossible to keep the room comfortable and when it gets nice and warm in Summer, your beautiful conservatory turns into a greenhouse!

If you’re fed-up of being either too hot in Summer or too cold in the Winter, then make the change.
By replacing the existing roof on your conservatory you’ll be creating a comfortable environment and a room you can enjoy all year round, plus your heating bills will be slashed. You’ll be amazed at the difference it will make to your home, in fact, it will literally transform your whole ground floor living area to give you the room and living space you always wanted. A room you can use everyday come rain or shine.

  • The Guardian™ roof

    The lightweight, insulated Guardian™ roof system was designed and developed over a ten year period and with one purpose – to replace the typical glass or polycarbonate roof that was used in the construction of most UK conservatories.

    The main focus was on the dynamics and performance, however the overall weight of the replacement roof, which needed to be installed onto the existing conservatory windows, doors and frames was always a big priority. During this period extensive tests were carried out both for compliance and approval to very vigorous structural and thermal standards. The result is not only a brilliant product but a very practical solution, one which has been the biggest home improvement.
