The Best Types of Roof Insulation for Self-Builders

Insulation is one of the main areas you need to take care of when building your home, in part because you have to comply with current building regulations. However, that’s just a part of the overall reason.

How much insulation you decide to put in and what type you use can influence the result.

According to the Energy Saving Trust UKabout a quarter of heat is lost through the roof.

Clearly, roof insulation is something that should be on your checklist. It can help you get energy savings of up to £250 every year.

The good news is that if your loft is easy-to-access and doesn’t have any dampness issues, it is possible to do it yourself without having to hire a pro.

However, before you start working on this project, it’s best to take note of your insulation options.


The proper way to evaluate a type of insulation is by looking at its properties.

With that in mind, we’ve covered several important aspects about SuperFOIL multilayer foil insulation.


  • It provides a barrier for the movement of air and controls air leakage.
  • It helps prevent radiant heat transfer. Other attic insulation materials only help to reduce conductive heat (R-Value) flow. As a result, the insulation heats up, and the heat is transferred into the home. Reflective insulation will help reflect heat coming off the roof, thus reducing the insulation temperature.
  • SuperFOIL insulation is thinner and lighter compared to other types of insulation. Thus, it takes up less space.

All these properties translate into significant benefits that can turn any roof insulation project into a success.


  • The control of air leakage leads to the further improvement of energy efficiency. As a result, it reduces your energy expenditures.
  • By reducing heat flow due to radiant heat into the home, reflective insulation enhances your comfort. 
  • It’s easy to handle, install, cut and seal. Moreover, you can find step-by-step instructions here on how to install SuperFOIL insulation. Also, its size makes it very versatile so that you can use it all over your home.


One of its main advantages is cost, you’ll be hard pressed to find a cheaper form of insulation, the downside to this of course is that its relatively low performance and as such requires a lot of space.

This material will slow down various forms of heat transfer. However, compared to reflective multifoil insulation, it has very low reflective ratings.

Yet, it has very high emissivity ratings. That means that it won’t be as effective when it comes to helping reduce radiant heat transfer.


The advantage of using this type of material is that it’s lightweight. Just like the case of reflective foil, this makes it easy to handle and install.

However, polystyrene panels do pose certain environmental issues: When burnt, they emit toxic smoke. 

Also, this type of material has the same shortage as mineral glass when compared to reflective insulation: It won’t do a good job when it comes to helping prevent radiant heat transfer.


Getting roof insulation is a smart investment that will pay off in the long run.

Once installed, it will silently do its job, and you will start to see improvements almost immediately.

Also, you shouldn’t be required to put any effort regarding maintenance.
