Conservatory roof insulation panels - the Sagars solution

Are you looking for a cost-effective way to transform your conservatory? Then our conservatory roof insulation panel solution is absolutely the answer.

Many of our thousands of happy homeowners begin their search for ways to upgrade their conservatory by looking at ways to better insulate the space. Too hot in winter, or too cold in summer? The most likely culprit is a poorly insulated ceiling, likely made from polycarbonate or single-sheet glass. High energy bills, a space that’s only good for drying clothes in summer, or chilling the festive fizz in winter. Sound familiar?

Well, no more! At Sagars, we transform tired, damp conservatories into your new favourite room in the house with our tried-and-trusted conservatory roof insulation panel solution.

For the fraction of the price of a new roof, or a new conservatory, or even a brand new extension, our conservatory insulation panel solution will make your space feel like a true extension of your home, and a space you can enjoy 24/7, 365 days a year.

How does our insulated conservatory roof panel solution work?

To put it bluntly, our conservatory roof insulation system is an upgrade on just installing conservatory insulation panels. Longer-lasting, better outcomes, and a fantastic end product.Our approach to conservatory roof insulation follows a two-step process:

Step 1: Insulation installation

The team starts by fixing an insulated multi-layer foil quilt system to your existing conservatory roof. Our system is market-leading and equivalent to around four inches of traditional loft insulation, with built-in vapour control to manage condensation an heat transfer.

Step 2: Choose your ceiling finish

This is the exciting bit - once the installation is installed, you can choose whether to finish your ceiling with conservatory ceiling panels (our popular white PVC boards) or a fresh render finish to make your ceiling look like a brand new extension. We can even install ceiling lights, a skylight, and ceiling fans too. This choice in finish and our market-leading insulation system combined are why the Sagars approach to conservatory roof insulation pannelling is so effective: highly-effective insulation properties, with the flexibility to choose the ceiling finish you’d like.

Optional Step 3: EcoSlate 365

Now, if you REALLY want to transform your conservatory inside and out, you can also opt for our incredible EcoSlate solution. Homeowners are raving about EcoSlate because it delivers a slate-effect roofing finish to the outside of your conservatory. But, crucially, these slate-effect tiles are super lightweight. That means we can fit them to most existing conservatory structures, without extensive modifications or the need for planning.

Why is Sagars’ solution an upgrade on a traditional insulated conservatory roof panel?

Traditional conservatory insulation panels work by sitting on top of your existing roof structure. They can be effective at improving the ambient temperature of your conservatory. But, if we’re being honest, we don’t think they look that great, and they give homeowners less choice in how they want their conservatory to actually feel.

The Sagars alternative solution to conservatory insulation panels actually makes your space feel like a true extension of your home. All the work can just be carried out internally with our conservatory ceiling insulation, and you can choose the ceiling finish you would like - traditional PVC planks or modern render.

And if you would like to transform the outside of your conservatory too, you can do with our fantastic EcoSlate 365 solution, so your conservatory roof will more closely mirror the roof on your home.

Our alternative to conservatory roof insulation panels is long-lasting with a cast-iron 10-year guarantee, it looks beautiful, and we truly believe you’ll love the finished result a lot more than simply installing some insulated panels to the roof.

Are insulated conservatory roof panels any good?

Insulated conservatory roof panels can improve your home’s energy efficiency, lowering your energy bills and better for the environment. They can be installed in a day but definitely aren't the most affordable or effective way of insulating your conservatory roof.

What is the cheapest way to insulate a conservatory?

A lot of people think that installing conservatory roof blinds is the most affordable way of insulating a conservatory but even we were surprised that the average cost of these blinds is £4,525. For a more permanent, efficient and affordable option, we recommend Sagars 365 conservatory roof insulation.

How much heat is lost through a polycarbonate conservatory roof?

Polycarbonate is actually reasonably good at keeping heat in in the winter, however the way that a conservatory is designed, heat is lost through all the gaps and the biggest gap is in the peak where a brush, or foam insert is the only thing stopping heat escaping as it's designed mainly to stop debris blowing in Sagars solution insulates and seals al the air gaps.

How much difference does an insulated conservatory roof make?

We conducted a survey with our customers that have our insulation installed, the results were incredible. A staggering 58% of our customers have seen their energy bills reduce by more than 25% following their Sagars 365 conservatory roof insulation. Not only does it reduce you energy bills, it also keeps you warm during winter and prevents overheating during summer, as well as reducing your carbon footprint.
