Insulting your outdoor shed will not only help to keep it warm in the winter but also cool in the summer months too.
Insulting your shed doesn’t have to be a hugely costly job, it can be done relatively cheaply and still have a big impact on climate control in the outdoor shed.
You’ll need to consider insulating the floor, roof, windows and doors as well as the walls to ensure full insulation.
When it comes to insulation materials, you’ll need to consider the R-value of the material. The higher the R-value, the better it is at insulating your shed.

Best Insulation For Sheds

There are multiple options for materials when it comes to insulation for a shed, here’s a quick run-through of what you can choose.

Bubble Wrap:

Bubble wrap is the cheapest way to insulate your garden shed, and it can sometimes be the option on how to insulate a shed for free, depending on whether you have some lying around or not. Bubble wrap isn’t as effective as some of the other materials listed below, but it still offers an effective solution for helping to insulate a shed.

Fibreglass Wool:

Simple to install, fibreglass wool is a good insulator for your shed. The fibreglass wool’s structure makes it a great option as it’s full of air pockets that ensure it keeps its form over time, which can make it a cost-effective solution in the long run. The big downside to using fibreglass wool to insulate your shed is that you’ll need to ensure that you protect your eyes, nose and mouth, as well as wearing gloves when you install the fibreglass.

Rockwool Insulation:

Rockwool or mineral wool is similar to fibreglass in that it can be irritating to your skin if you touch it, so you need to keep protected if using it. But it’s a great option for insulation, especially if you’d like some sound protection for your shed too.

PIR insulation boards:

Commonly referred to by the brand name Celotex, PIR insulation boards are a popular choice because they can be used on walls, floors and roofs too. They come in standard sizes that fit most sheds, but they’re also easy to cut into the desired shape if needed. Polyisocyanurate (PIR) boards are the more costly choice when it comes to insulating a shed, but their design makes it worthwhile with thicknesses ranging from 50mm to 150mm and their foil-backed design creates an extra thermal barrier, as well as a vapour control layer.

How To Insulate A Shed - The Different Parts

When it comes to the different areas of the shed, such as the roof, door and windows, there are other materials that you might consider for insulation.
You’ll need your roof to be water-resistant as well as be able to reduce heat loss. Roof felt is a great option for this. Celotex boards are another great option for roof insulation in a shed.

When it comes to insulating a shed door, the simplest option is to stick rubber strips to the inside of the door frame to help create a seal along the door crack when it is shut.

If you find that your shed window has any gaps that need to be better insulated the easiest option is to fill them with a tube of ‘liquid’ wood or a foam filler.
The best insulation for a shed all comes down to personal preference and the type of shed you have. If you’re looking for tips on how to insulate a shed for free then you’ll have to use items you already have such as bubble wrap, or cardboard boxes, but both of these options aren’t really lasting solutions, just a quick fix that will last a little while.
