How can I keep my conservatory warm in winter and cool in summer?

Conservatories always seem like a great addition, but they are usually the least used room in a house. Often too hot in summer and too cold in winter. Not only are can the be uncomfortable to sit in, but if uninsulated, in the winter they draw heat from the adjoining rooms and the rest of the house creating cold spots in the house. Low-E insulation is made from a 99.4% pure aluminium with a recycled closed cell foam core. Our pure aluminium facing is not a Mylar and ensure Low-E will reflect 97% of radiant heat that come in contact with the surface.

How do I stop Draughts in my conservatory?

There are lots of different types of conservatory frames and glazing system. Some are more thermal efficient and draught proof than others but most old style systems are very draughty. This can cause draughts through your home as well as the conservatory itself. The easiest way to stop draughts is to use an insulation system with a air barrier or better yet an insulation material like Low-E that will reduce or stop draughts altogether. Remember reducing draughts doesn’t necessarily mean sealing up the whole building. You can insulated and reduce draughts while still maintaining breathability.

Is it worth insulating a conservatory roof?

The short answer is yes, having an insulated conservatory roof is VERY worthwhile, for numerous reasons; 

  • It will give you back use of extra square footage in your home and increase the value of your property. 
  • It will make your home more thermally efficient and reduce your energy bills 
  • It will reduce rain noise  

Is it safe to insulate a conservatory roof?

There are lots of companies offering conservatory roof insulation system. Like I said previously, some of these are installed from the inside and some from the outside. The risk with insulating a conservatory roof is adding weight to the roof that the roof system has not been designed to take. In recent years there have been numerous reports of conservatory roofs collapsing after additional weight has been added to the roof.

The most important thing is to ensure the roof can take the additional weight, use an installer that is qualified and insured to carry out the work. I would always recommend using our unique Low-E Insulation which weights less 150g/m2. See below for details of a Low-E approved installer who will assess your roof and determine the safest and most efficient way to insulate it.

What is the best way to insulate a conservatory?

The best way to insulate a conservatory roof is to ensure the materials you specify tick all the boxes and address all of the issues your existing roof is causing.

Make sure it will reflect solar gain (radiant heat) rather than just looking ‘shiny’, or slowing down conductive heat loss (traditional insulation). To understand the difference between ‘shiny’ mylar type insulations and Low-E Insulation your should read our blog How Does Low-E Compare?

“What can I say? The insulate was quick clean and easy to install. Our original loft conversion was done over 20 years ago, and it has gone from being the hottest room in the summer, and the coldest room in the winter, to being our master bedroom and the most comfortable room in the house."

We use both the vapour and the breathable versions of Low-E Insulation. We’ve tried using other foil insulation products, but they can be time-consuming and difficult to install. Low-E is so easy to work with, we just wouldn’t use anything else.

G Stone

“I’ve been specifying the use of Low-E Insulation for the last 5 years. It’s a fantastic product. It achieves better values in smaller spaces than other materials. Best of all, Building Control love it and so do our contractors.”

“We’re part of the Insta Group and have been installing loft insulation in Manchester for over 10 years. I’ve never come across a product as good as Low-E. It quick clean and easy to use. Our customers are delighted with it. I’ve been so impressed with it that I’ve re-insulated my own loft.”

“The installation was quick clean and efficient. The results are amazing. Our conservatory is comfortable even in these record-breaking summer temperatures.”

Mrs Staff

“Low-E was a critical part of our insulation build up. Without it, we would not have been able to meet our brief. The contractor was very happy with it because it was quick, clean and easy to install”
