Best Shed Insulation

Sheds are a really versatile addition to any outdoor space, and can be used to store essential gardening tools in, as a workshop for creating amazing crafts and DIY projects or as the infamous ‘man cave’ in order to escape for a while.

Whatever you use your shed for, it needs to be properly maintained in order to have a long life. You might think this is as simple as painting it with a coat of wood protector once a year, but although that is also essential maintenance, another way to prolong the life of your shed is to insulate it.

Insulation does so much more for a garden shed then providing it with warmth over the winter months. It can also keep it cool during the summer, which in turn can keep your expensive equipment and tools in good condition, as well as provide protection against damp and mould growing and damaging the wood. Shed insulation can even help reduce noise pollution so you can carry on working without disturbing anybody.

Best Shed Insulation – Buyer’s Guide

Adding insulation to your shed does so much more than just keep it warm during the winter months, and can actually help to prolong the life of many garden buildings by reducing the risk of damp and reflecting heat away from the roof.

However, there are a few things you need to consider before diving straight in and purchasing the first insulation you come across. Below, you’ll find some important points to bear in mind before making your final decision, and that will ensure you get the best shed insulation possible for your individual needs.

Size

The first thing to consider is how much insulation you need in order to cover your shed. Bear in mind that insulation is most effective when the walls and the ceiling is covered, so it’s worth heading out into your garden with a tape measure and jotting down some figures.

Once you’ve got your measurements sorted, you can then make an informed decision on how much insulation you need. You’ll mostly find that insulation is available as single rolls or in multipacks, but check to make sure how cover each roll will give you so that you don’t end up with too little or not enough.

Thickness

The next thing to look at is how thick the insulation is. Traditionally, insulation was made of super thick materials that were tightly packed into a membrane casing. However, developments in materials and technology now mean that this is no longer the case, and you can get insulation that is much thinner (around the 4mm mark) that still provides the same benefits as thicker materials.

Not only is thinner insulation a better, space-saving alternative to the old fashioned stuff, but it’s also much lighter in weight. This means that you can install it to the walls and ceiling of your shed without needing to worry about it adding any heft to the structure and potentially weakening it, which is less than ideal in stormy, winter weather conditions.

Installation

So, you’ve found insulation that is the right size and thickness for your shed. The next thing you need to think about is how you’re going to actually get it onto the walls and the ceiling.

The last thing you need to be doing is trying to keep your insulation in place with one hand whilst you try and secure it with nails and a hammer in the other! Luckily, most modern insulation is designed to be easily installed simply by stapling it into place with a staple gun, and when you combine this with the lightweightedness of it, the job of installing becomes even easier.
Another thing to think about is if your shed or summer house has any irregularly shaped walls or ceiling panels. If it does, your best bet would be to look for insulation that can easily be cut into that shape with a pair of scissors, allowing you to get the perfect fit and covering every inch of your shed adequately.

The final thing to remember when you’re installing insulation is that you’ll need to seal the joins between each panel of insulation to create a tight, secure bond. This is best done with insulating tape, and it’s usually a good idea to use the same brand of tape as the insulation.

Material

The material that your insulation is made from will have a direct impact on the performance of it, so it’s definitely worth looking to see what components make it up.

As we know, advances in fabric technology mean that the insulation doesn’t have to be thick, and materials such as bubble polyethylene will provide warmth at a fraction of the thickness of more traditional insulative materials such as fibreglass.

You’ll notice that modern insulation also tends to have aluminium external layers. This gives the insulation a dual ability of keeping interior warmth during cold weather, but also acts as a reflective layer that stops the shed becoming too hot internally during the summer months.

Lots of insulation also incorporates recycled materials into its construction, which is a great eco-friendly choice and is perfect for anybody that is keen on using sustainable materials as much as possible.

Water Resistance

When you’re installing insulation into a shed, it’s absolutely essential that it is waterproof or water resistant, and well as corrosion resistant. This ensures that no water can enter the shed and lead to condensation becoming trapped.

The problem with trapped condensation is that it leads to damp and mould, which can cause irreversible damage to the wood in your shed and can leave you with the rather costly expense of having to replace it altogether.

Insulating your shed and ensuring that the insulation itself is water resistant will prolong the life of your shed and make sure that it’s kept as dry as possible internally.

Noise Pollution

Another fantastic feature to look for in any shed insulation is whether it offers to reduce any noise pollution.

Absorbing excess noise coming from inside the shed will allow you to carry out various DIY tasks without causing any annoyance to your neighbours or the rest of your household, and reducing the noise coming from outside your shed will provide you with a quiet place to relax away from it all for a while.

Price

Shed insulation can be an expensive investment, albeit a worthwhile one. So it’s a good idea to set yourself a budget before you start shopping so that you don’t end up spending more than you can afford.

Be sure to look at all the features that your shed insulation offers you, and if you’re still unsure, then order just the one roll to begin with. If you’re satisfied with it and think it’s worth the money, you can always order more of the same later on.

Frequently Asked Questions

Do I need to insulate my shed?

Although insulating a shed isn’t imperative, it is highly recommended as it will help to reduce the risk of damp or mould, keep the wood healthy by regulating the temperature and will also keep any tools or expensive equipment you’re storing in your shed safe from overheating and rainwater.

What materials insulate the best?

For insulating a shed, we’d recommend looking for insulation that is made of multiple layers. Usually this will be an internal layer of bubble polyethylene to keep everything warm, and outer layers of aluminium foils that reflect heat away from the shed during hotter months. It’s also a really good idea to check that the insulation is water resistant as well.

How easy is it to install insulation in a shed?

Modern insulation is actually really easy to install into a shed, and can simply be cut to the desired size and then stapled into place with a strong staple gun. Use insulative tape to seal the gaps between the panels and the job is done! For the best results, make sure that you apply insulation to the walls and the ceiling as this will prevent any drafts, hot spots or leaks from occurring.
