A smarter, lower-cost way to transform your conservatory
Turn your conservatory into a comfortable, usable living space all year round. Polar Insul-Roof is a high-performance internal roof insulation system that keeps your conservatory warmer in winter, cooler in summer, and far more energy efficient. Conservatories are notorious for extreme temperatures — overheating in summer and losing heat rapidly in winter. This often leaves the space unused for much of the year.
Polar Insul-Roof solves this problem by insulating your existing conservatory roof from the inside, dramatically improving thermal performance without the cost or disruption of a full roof replacement.

Is Your Conservatory Too Hot or Too Cold?
Conservatories are notorious for extreme temperatures — overheating in summer and losing heat rapidly in winter. This often leaves the space unused for much of the year.
Polar Insul-Roof solves this problem by insulating your existing conservatory roof from the inside, dramatically improving thermal performance without the cost or disruption of a full roof replacement.
What Is Polar Insul-Roof?
Polar Insul-Roof is an internal conservatory roof insulation system designed specifically for glazed and polycarbonate roofs. Installed entirely from inside your conservatory, it transforms temperature control while maintaining a clean, modern internal finish.
How the Polar Insul-Roof System Works
Our experienced installers follow a proven, high-quality process:
-
Timber Battens Installed
25mm dry-treated timber battens are fixed to the underside of your existing roof structure using specialist fast-fix screws. -
High-Performance Insulation Fitted
We install YBS SuperQuilt, a fully certificated 19-layer multifoil insulation with true aluminium outer layers. -
Counter-Battens & Airflow Created
A second layer of battens compresses the insulation while creating airflow and secure fixing points. -
Clean Internal Finish Installed
Your chosen internal lining is fitted, creating a bright, modern ceiling finish.
FAQs
Will this stop my conservatory getting cold?
Polar Insul-Roof significantly improves heat retention and overall comfort, making the room far more usable year-round.
Will it make the room dark?
The system reduces glare while still allowing natural light through the roof. Optional lighting can also be added.
Is this better than a full warm roof?
A full warm roof provides the highest thermal performance, but Polar Insul-Roof offers excellent improvement at a much lower cost.
Do I need planning permission?
No. planning permission is not required for a Polar Insul-Roof, as the installation does not involve altering the external structure or appearance of the conservatory roof. Since the work is limited to internal improvements,
this falls within permitted development rights.
Can it be removed in the future?
Yes. The Polar Insul-Roof system is fully reversible should you wish to upgrade further in the future.
Will I see the insulation through the glass?
if your conservatory roof is made of glass panels, our team of expert installers will apply ThermaFrost Window Film to the inside surface of the glass. This creates a white, opaque finish on the roof, effectively concealing
the insulation from external view.
