  • 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.

  • A bit about us?

    Classic Windows was founded by the directors who have had over 20 years experience in the home improvement industry.

    The company is a family run business offering top quality products for a fraction of the cost that larger companies would charge without diminishing the quality. Classic Windows experienced team of installers can take care of your project from the initial design and planning permission to the completion of the job.

    We have recently obtained a government-backed ‘Trustmark’. Which is a scheme used to protect customers from rogue traders, giving you peace of mind when you use Classic Windows.

    We look forward to giving you the service that you deserve when looking to improve your home.
