Warmer in Winter Cooler in Summer

Can you honestly say that you are getting the most out of your conservatory?

That's where the Sagars 365 conservatory roof insulation system comes in!

For many people, a conservatory is a dream addition to their home. A perfect way to enjoy your garden, a much needed extra room in a crowded house. But as you may know if you were the one that paid for it, they are not cheap - plus there's the hassle of getting planning permission.

Sagars 365 Conservatory Insulation System

Using the revolutionary 365 insulation system, Sagars 365 can transform your conservatory and make it into a room you can use 365 days a year. The conservatory insulation is built up of complex layers of aluminium foil, finished with tongue and groove insulated UPVC panels to give a maintenance free bright appearance. Reducing heat loss in winter, and keeping the heat out in summer.

We use a multi-layered foil insulation system, specifically developed for conservatory roof insulation which is equivalent of 4 inches of loft insulation. The system was inspired by NASA, who use multi-foil insulation to protect the equipment and crew of their spacecraft from the extreme conditions of space travel.

Multi foil insulation is often carried out on new builds, but it can also be added to older properties. More energy efficient than many traditional types of insulation, it’s easy to install and has a number of useful properties, such as:

  • Vapour control – this stops the insulation becoming damp, keeping it effective
  • Can be used alone or with other insulation
  • The foil layer reflects heat, stopping it escaping the building
  • Thinner than traditional insulation, making it suitable for walls, floors, or ceilings


Our fitters install your insulation contact free, keeping everyone safe during the ongoing pandemic. They enter and leave your conservatory using an outside door, with the inside door to the house locked, to ensure they adhere to government social distancing guidelines.

If required, our opaque frosting is measured and fitted to the inside of the conservatory roof so the insulation cannot be seen from above. Next, the insulated multi-foil quilt is added. the quilt covers the entire underside of the conservatory ceiling. Finally, the lightweight UPVC plastic cladding is installed to give you that professional finish. And we will always leave your conservatory nice and tidy, just how we found it.
