How to Properly Insulate a Garden Shed

Posted on Feb 1, 2016

Your child’s first shoes, your wife’s collection of CDs, the clothes you wore to your prom and about a million of Polaroid photos from the 1990s – these are all valuable memories, but how often do you use them? They do not belong in your house because of the lack of space, but are to be safely stored in a garage or a shed. In order to ensure protection, your shed has to be adequately insulated and protected against all weather conditions. To do it properly, you have to invest some money, effort and time, but, if done right, a shed can even become an area to grow plants, set up a gym or store food. Therefore, here is how you should insulate it.


While you may have noticed sheds that look quite fancy and stylish, they are usually not. They were probably built several decades ago and most of them have not been taken care of properly since then. Due to that, your first goal must be concerned with the structure and sealing everything tight. This includes replacing windows, patching the roof and fixing the walls. When it comes to windows, the best way to go is choosing double glazed ones – they have two layers of glass with an extra layer of air for additional protection. This solution will ensure that your shed is properly sealed and protected, claim at a Perth-based company specialised in double glazed windows.

Once this is done, you can move to the walls and the roof. You need to inspect their condition and identify all cracks and gaps, which are then seal with caulk and spray foam. While some professionals apply the former only to bigger holes, do not be afraid to use it with the smaller ones as well – the smarter you use it, the better your job will be. Ultimately, check if your roof is leaking and pay attention to the drainage system.



The first thing you need to do is gather proper measurements – determine the width of the free space between the studs of your wall and you will know how wide your insulation has to be. No matter what kind of insulation material you plan on using, these measurements will be the basis for your project, so make sure they are as precise as possible.

When speaking of the choices you have, most people use wool insulation, foam filling or foil-faced insulation. All are, of course, great choices that provide thermal and sound protection, but there are a couple of details that separate them. Wool, much like fiberglass, is perfect if you want to use your shed actively all through the year and in all temperatures and conditions. Foam is an elegant solution for walls equipped with a layer of drywall, while foil-faced insulation is easy to install at all sorts of walls. You can do it on your own in just a couple of hours.



Once you have settled for a particular material you wish to use, it is time to do the job! If you choose foam, be sure to contact an expert – you can do it on your own, but a professional will surely do a much better job and still not be too expensive.

If you, however, pick polystyrene or foil-faced sheets, your job will be much easier. All you need to do with the former is set the sheets against the frame of your shed, glue them with an adhesive and hold tight for a couple of seconds. For the foil sheets, you will need to secure them to the walls with a staple gun and make sure they overlap, thus creating a better connection between separate sheets.

Finishing Touches

What you must not forget is insulating the ceiling of the shed and, finally, covering the insulated walls with drywall sheets. This way, you will make your shed nice and welcoming from the inside as well, and you will be able to spend some quality time there, too.

About Lillian Connors

If one thing is true about Lillian Connors, her mind is utterly curious. That’s why she can’t resist the urge to embark on a myriad of home improvement projects and spread the word about them. She’s also deeply into green practices, cherishing the notion that sustainable housing and gardening will not only make us far less dependent on others regarding the dwellings we inhabit and what we eat, but also contribute to our planet being a better place to live on. When she is not trying to improve the things around her (and herself, for that matter), she likes to lose herself in a good book and sip on an occasional appletini.
