How conservatory roof insulation works

Many conservatories become uncomfortable during very hot or cold weather. Sagars 365 roof insulation can reduce heat transfer through a suitable existing roof and create a clean PVC or plaster ceiling. Final comfort and any energy saving depend on the glazing, doors, floor, heating, ventilation, room size and how the conservatory is used. Start with a free home survey and a written quotation.

Our Process

Every conservatory is different but no matter what your current set up is we can work within your requirements and specifications to get the result you want. In the project below the customer had originally fitted a ceiling fan to combat the summer heat but it wasn’t very effective. We removed the ceiling fan and light fitting and installed modern spotlights in their new ceiling. There was no longer any need for a fan as the insulated ceiling keeps the room cool in the summer and warm in the winter!
Sagars 365 conservatory roof survey and assessment
Step One
When we visit to assess your conservatory, we take the time to understand both the space and your needs. We'll carry out a full site survey, taking accurate measurements and discussing in detail how you’d like to use your conservatory , whether that’s for year-round living, a home office, a playroom, or simply a more comfortable space to relax. Once we’ve established what you want to achieve, we’ll explain your options clearly and talk you through the best solution for your home. If you’re happy to go ahead, we’ll then arrange an installation date that works for you.

Step Two
Time to get to work! We began by removing the existing ceiling fan and light fitting to clear the space. Next, we installed high-performance insulation designed to retain heat during the colder months, making the space far more energy efficient. Our electrician also got started on fitting the necessary cabling for the new spotlights, ensuring everything is ready for the final installation.In this particular project, we installed our PVC ceiling finish, a cost-effective option that’s perfect for those who are budget-conscious but still want a clean, modern look. We also offer a premium plastered ceiling finish for a more traditional feel, as well as a fully tiled roof option for those looking to go all-in on insulation and visual transformation. Whatever your needs, we’ve got a solution to suit.

Step Three
Once the timber framework was in place, we began fitting the PVC cladding, creating a clean, modern ceiling that instantly refreshed the look of the conservatory. As part of the upgrade, the old ceiling fan was removed, making way for a more streamlined and practical lighting setup. We installed a set of integrated LED spotlights, which not only brighten the space beautifully but also add a touch of contemporary style. A range of LED lighting options is available, so you can choose the look and feel that best suits your home. The end result is a lighter, more comfortable space that feels like a true extension of the home.

Premium Plastering Ceiling

Although PVC is very popular you always have the option of putting in a plaster ceiling that makes the conservatory feel like any other room in the house.
Plastering a newly insulated conservatory ceiling
Step One
No more worrying about condensation or heat loss. We use only the best and most up-to-date products and installation methods on the market to ensure a high-performing, long-lasting result. The owner of this large conservatory had struggled for years to retain heat, but with such a vast ceiling area, it simply wasn’t possible without proper insulation. We knew that once we fitted a fully insulated ceiling, that would no longer be a problem.

Step Two
For this project, the customer chose a smooth, plastered ceiling finish. We began by fitting the insulation and timber framework, followed by the installation of plasterboard. Everything is now prepped and ready for plastering. Even at this stage, the transformation of the room is already clear. Although no lighting was requested, the ceiling has been constructed to easily accommodate any type of lighting, had it been required.

Step Three
Once plastered, the result is a fully insulated, finished room that gives you extra living space without the need for an extension. You gain valuable, usable space within your home. Once the plaster has dried, you can paint it any colour you like. In this case, our client chose white, creating a bright, fresh and airy feel that really lifts the room.
