How to Insulate a Garden Shed



As the nights start to draw in and the evenings get cooler, the humble garden shed becomes less of an appealing place to be, but it doesnt have to be this way. Your shed can remain just as functional and comfortable as during those warm summer months, with a little bit of knowhow and at a very reasonable price!

First though before anything else, make sure you have treated your shed with a good quality timber preservative to protect it from rot and the horrid winter weather. You can check out our more in depth guide here.


The average garden shed isn't equipped with any form of insualation and can be quite draughty, especially if you're in an overlap building. A cheap and cheerful means of insulating your shed is with a good amount of bubble wrap!
Large rolls of the stuff can be bought from most DIY or even stationary stores as well as online. It may sound silly, but the wrap helps to trap air, in addition to the bubbles themselves helping to insulate the inside of your shed. This is great for both tongue & groove and overlap buildings of any size or shape. Bubble wrap sheets are simple to install with a staple gun or thumb tacks and can be used on the roof as well of the walls to prevent draughts and keep your shed feeling snug!






If bubble wrap doesnt appeal, or you fancy kitting your shed out your shed with something a little more effective in the winter months, then traditional wall insulation is another option. While perhaps a bit more time consuming, the benefits far outweigh the added time of getting it on the walls. Fibre glass wool offers similar insulation to what you'd find in your home and can be found in DIY stores and online.

Insulate your Garden Shed

First of all, you're going to need to make sure that your insulation isn't going check inside and make sure you haven't got any damp areas or gaps where water could get inside. If you do, don't panic, check out our damp proofing guide here!

The best thing to ensure your insualtion stays as dry as possible is to first fit a breathable membrane in front of the shed cladding. You'll need to place some additional batons within the framing and tack the membrane to these. This is to stop the membrane actually touching the walls of your shed and creates an air pocket; you want any moisture entering the shed to evaporate.

Next up is the insulation itself. Fiber Glass Wool can now be laid over the top of the membrane, between the shed framing. Avoid compressing the fiberglass as this will make it a less effective insulator. You can then cover over all of this with MDF, plywood or OSB and tack the boards into place at the framing points to retain the fiber glass wool.

Don't be tempted to use plasterboard, this might be great for indoors but leaning a heavy bike against it is going to leave a nice big dent! This type of insulation is great for the roof of your building too where most heat loss tends to occur. Follow the exact same steps for a cosier shed in no time.





Of course, the shed you buy in the first place greatly impacts the effectiveness of these insualtion techniques. While Overlap is perfectly suitable, a tongue and groove building will put you at an advantage as the cladding interlocks, preventing the vast majority of draughts and helping to prevent damp.
