Conservatory Roof Insulation – Professional Installation

Conservatory Roof Insulation

The least used room in any home is the Conservatory.

In summer, Conservatories become uncomfortably hot to enjoy and in winter freezing cold, making it a completely useless room!

You can solve this problem by installing Conservatory Roof Insulation.

For the majority of the Year, a Conservatory simply cannot be used. In our opinion, a Conservatory is one of worst drains of energy in your home and if yours is not insulated I think you will agree with us.

So, you’re paying costly energy bills to heat your conservatory just for the energy to escape through the plastic or glass panels above,

Here is our guide on how to make your Conservatory an comfortable, usable room all year round.

If you have a Conservatory the best investment you can make is to have it Insulated with Multifoil Insulation products and if you have the required skills you could Insulate it yourself.

The following Questions & Answers explain what you should and shouldn’t do and how to carry out a D.I.Y Installation and also explains the importance of the correct procedures and why our ConservaHeat system is the best option when it comes to Conservatory Insulation.

QUESTION: Should I attempt the job of Insulating a Conservatory myself from the inside?

ANSWER If you are capable of fixing studwork & timber battens to walls or ceilings and you have someone to assist you are off to a good start, however I strongly advise watching a good ‘How To’ video.

QUESTION: Are there any Companies or products that should be avoided?

ANSWER:  Yes. Some Conservatory Companies use “Rigid” PIR products like Kingspan & Celotex. The issue with these products is they need to be very thick to give the same heat retention as Multifoil Insulation products. It is also very difficult to achieve an airtight seal compared to using a Multi-foil blanket. There is also significant wastage when cutting PIR and requires a mask to avoid breathing in the dust. Personally, I would never use SuperFoil Insulation which is manufactured in China. SuperFoil is made from an inferior metalized plastic foil that is made to look like true aluminium foil, however it does not reflect heat in the same way. Importantly SuperFoil is also highly flammable. So Beware, it is very easy to confuse genuine true aluminium SuperQuilt which is manufactured in the UK. One of the companies that uses the Chinese SuperFoil is Rundle and Dorey, which I would avoid for this reason. I would go with ConservaHeat as a superior alternative and designed specifically for insulating conservatory roofs- visit https://www.conservaheat-insulation.co.uk

QUESTION: Is it better to fit Plasterboard or UPVC cladding internally

ANSWER: Plasterboard finish can look nice, however the plaster can crack as you can get movement and will need painting every few years or so. With UPVC or Timber Cladding, you do not have this problem and can be installed by a good D.I.Yer where plastering is a skilled trade. UPVC is also is zero maintenance.

QUESTION: Should I use a film on the inside of my Conservatory Roof or will I be able to see the foil?

ANSWER: If your roof is poly carbonate or opaque there is no need to fit a film first unless you do not want the foil to be seen. Most people consider the foil looks appealing from the outside. Importantly it allows full reflection of radiant energy without any barrier.
It is always recommended to fit a film to clear glass Conservatory Roofs. The Thermafrost Conservatory Tint Kit can be ordered HERE.


QUESTION: Is planning permission or building regulations required to Insulate a Conservatory?

ANSWER: To Insulate outside the Conservatory Roof requires Building regulation. It is much easier and much more cost effective to insulate a Conservatory from the inside, in which case none is required.


QUESTION: Can a Conservatory take the added weight of Insulation.

ANSWER: According to the designers of ConservaHeat Insulation System the average weight of the Insulation is only 7 Kilos over the average 15m2 Conservatory.
Even with the 25mm battens and UPVC cladding the weight is minimal. The installers of ConservaHeat have Insulated over 15,000 Conservatories in the last 5 Years and includes a 10 Year Insurance backed guarantee they claim has never been used for this reason. The company also has the highest rating on the Guild of Master Craftsmen and inspect every Conservatory prior to Installing the ConservaHeat Insulation System to ensure 100% applicable.
