Shed Insulation: How to Insulate a Shed

Do you have a shed in your backyard that's freezing cold in the winter and too hot in the summer? Whether your shed is new or old, there are many ways to insulate it and improve its energy efficiency. In this blog post, we'll show you how to insulate a shed and improve its energy efficiency, regardless of the climate.

How insulation actually works

Before you start, it’s important to understand how insulation works.

The simplest way to think about insulation is that it’s like a barrier between the inside and outside of your shed. In the summer, insulation helps keep heat from getting in. In the winter, it helps keep heat from escaping. All insulation works by slowing the flow of heat through walls, ceilings, and floors. The more slowly heat can move, the better an insulating material is said to be. 

Types of shed insulation

When it comes to shed insulation, you have a few different options. The most common type of insulation is glass fibre wool or mineral wool type products such as knauf or rockwool, which comes in batts or rolls. (The same applies to wool insulation, recycled bottle insulation and other fibreglass wool type insulation material.)This type of insulation is easy to install and provides a good level of thermal protection.

Another option is insulation boards from brands like kingspan or celotex, which are sheets of rigid foam board. This type of insulation is more expensive, but it provides superior protection against both heat and cold.

Finally, you can also use Reflective foil insulation or bubble wrap insulating materials, which reflects heat away from the shed. This type of insulation is lightweight and easy to install, but it needs to be installed correctly with an adequate air gap if it is to perform correctly.

The benefits of an insulated shed

While the process of shed insulation may seem like a daunting task, the benefits are well worth the effort.

By adding insulation to your shed, you can keep the interior temperature more consistent, which can protect any items you have stored inside from extreme heat or cold.

Additionally, insulated sheds tend to be more energy-efficient, saving you money on your heating and cooling costs.

In addition, insulation can help to reduce condensation and moisture build-up, both of which can lead to rot and mould.

And by keeping the interior of your shed more comfortable, you may find that you're more likely to use it as a workspace or for other activities. 

DIY or professional installation - which is better for you 

When it comes to insulating your garden shed, you have two main options: DIY or professional installation.

If you're handy and have some experience with home improvement projects, then DIY might be the way to go. However, if you're not confident in your abilities or simply don't have the time, then professional installation is probably the better option. Here are a few things to keep in mind when making your decision:

  • The size of your shed: If you have a small garden shed, then you might be able to get away with doing it yourself. However, if your shed is large  or complex, it might be better to leave the installation to a professional.
  • The type of insulation material you're using: Some types of shed insulation are easier to install than others. If you're using a type that's relatively easy to work with, then you might be able to do it yourself. However, if you're using a more difficult type, it might be better to leave it to the professionals.
  • Your budget: Installing insulation can be expensive, but it's an investment that will pay off in the long run. If you're on a tight budget, you might want to consider doing it yourself. However, if you have the money, it's often worth paying for professional installation.

How to insulate a shed

Most typical UK sheds have exposed timber studs. You can simply cut and friction fit the insulation in between the timbers. Leave a slight air gap between the insulation and the shed wall to prevent moisture build up. You might want to consider using a breather membrane or vapour barrier and covering the insulation with something like OSB timber or lightweight timber cladding to give a nice finished effect.

Installation tips

When installing shed insulation, it's important to follow the manufacturer's instructions carefully. Here are a few tips to help you get the best results:

  • Measure the dimensions of your shed walls and floor surface before purchasing insulation. This will ensure that you buy the right amount of insulation.
  • Fit insulation tightly together: This will help to prevent air leakage and ensure that the insulation performs as well as possible.
  • Leave an air gap between the insulation and the shed wall: This will help to with moisture control and keep your shed healthy and dry.
  • Dont forget about the shed roof and shed floor: The roof is often the most important part of a shed when it comes to insulation. Make sure to insulate it properly to get the best results. An existing shed floor in a wooden shed can be tricky to insulate unless you can access the floor joists. A new shed is much easier.

Costs and savings associated with insulating a shed

Insulating a shed is a relatively easy and inexpensive project that can make a big difference in terms of comfort and utility.

In terms of savings, insulating your shed is a relatively small investment that can save you money in the long run. By keeping your tools and equipment in good condition, you can avoid the cost of replacements. And by making your shed or garden office more comfortable to work in, you can save time and energy that would otherwise be spent on heating or cooling the space.
