How to insulate a Shed You’ve Built Yourself

Please refer to our simple to follow step-by-step guide to protect your garden shed by with the kit for insulation.

Step 1

To start your insulation, it is best to start by grabbing the staple gun with pre-loaded insulation. Begin at the wall closest to the door. Then, you can begin to staple the insulation onto the wall. staple about halfway back into the studs of the upright.

Keep your insulation stapled tightly and securely, which will give you a neat finish.

Step 2

Continue moving through the lower part of the shed, making sure to place your staples evenly across the wooden studs inside the shed. Be sure to staple the insulation securely around the window ledges.

Step 3

After the lower section of the wall is sealed and stapled then you are able to build the upper portion part of your wall.

Following the same technique, you should overlap this new layer of insulation by around 50mm with the lower layer of insulation on the wall.

Step 4

In the event that you own windows,, you can either put insulate directly on top of the window to provide additional insulation, or remove the insulation.

If you are choosing to cut the insulation away and keep your window, then continue to add the insulation straight over the top of the window and secure the staples around the window structure.

Step 5

With gloves that are active, grab your craft knife and cut the edges of the window frame and into your insulation.

Be cautious with this step as you don’t want to mark or damage the glass in the frame. The insulation should cut fairly easily, so force won’t be needed.

Step 6

Now, you should begin to tape walls with insulation by using the foil tape that comes in the kit. Tape any overlaps, edges and joints.

Step 7

Now is the time to begin installing the isolation on the roof. It’s easy to do however you might need assistance in putting the insulation overhanging. Staple the insulation of your shed’s roof onto the rafters made of timber.

It is essential to leave the space for ventilation in the process of stapling your isolating material on the roof. Don’t make it to be too tight, as if temperatures rise, it can create mould underneath.

Ensure you leave a 2 inch gap between the roof timber and insulation should be a sufficient gap.

Continue this process to ensure that the insulation for your roof is put in place.

Step 8

Then, you can continue with using the same technique to apply the insulation on the inside of the door to the shed. Find the insulation, then cut it to fit the door.

Staple the insulation to the wood rafters on the door. Ensure you staple the top and bottom areas down securely, so you don’t end up with any loose flaps of material. Keep your staples even and sporadic.

Then, take your knife to cut the handle and lock to eliminate the insulation material.

Step 9

If you would like to insulate your floor, you can apply the insulation for your shed floor and then staple the insulation directly to the flooring of your shed.

After the insulation has been put in, select 25mm or 1″ wooden batons, and lay them equally over the insulation.

Take a drill and screws to secure the batons. It could be an idea to pre-drill your holes before fixing the screws to the base.

Add a layer of plywood over the batons, which will act as the floor.

The air gap that is created between the insulation material and the plasterboard provides an air barrier that helps in insulating and protecting your shed from soil and moisture below the shed.

Step 10

It is recommended to take care to go around any joints or overlaps using the tape to ensure that you get the best from your insulation.

Now you can decide whether you want to put plywood on the walls of your interior to protect the insulation, and then decorate it as you wish.

You can now take advantage of your new, insulated shed.
