How to Insulate a Garden Shed

19 November 2010

Many of us just use our sheds for storage but if you want to use your shed as a woodwork studio, music room, garden room or office you will need a little insulation to get you through the winter months. Garden sheds do not have any insulation; they simply have wall panels. Without insulation the inside of a shed can be very cold and will have drafts.

Bubble Wrap

The cheapest way to insulate a shed is with bubble wrap. Bubble wrap can be purchased in large rolls from DIY stores. The air trapped in the bubble wrap and the shape of its surface helps trap air; this helps insulate the inside of your shed. Simply attach bubble wrap to the inside of your shed covering the roof and wall panel. You can attach the bubble wrap with a staple gun or small tacks.

Traditional Wall Insulation

One of the most effective ways of insulating a shed is to use fibre glass wool rolls. These sheets of insulation are thick and provide similar insulation to a home. Fibre glass wool traps air which in turn insulates the shed. You must make sure that when you install this type of insulation into your garden shed you cannot compress the sheets.

There is one problem with cladding the inside of the walls with this type of insulation. If rain or water seeps into your shed through its cladding it will soak the insulation and not dry. The way to prevent this is to line the inside of your shed before adding the fibre glass wool insulation. Choose a breathable membrane; this can be found at most DIY stores.

However, one issue with this is that any rainwater soaking into the shed’s cladding will no longer simply evaporate away, but will instead soak into the wool, rotting it over time. Therefore you may need to line the walls before insulating your shed to prevent damp from reaching the insulation. You can do this fairly easily by simply tacking breathable lining membrane onto the cladding before placing the fibre-glass wool and tacking the solid sheet wood into place.

However, this method has a similar drawback as any rainwater leaking through the cladding, which it bound to do at some point several years down the line, will be trapped between the cladding and the cladding and the membrane.

Insulate with Fibre Glass Wool

  • Tack a breathable lining membrane to the inside of your shed attaching with staples or tacks to the shed frame. This will stop leaking water getting into the insulation.
  • Tack extra batons to the shed wall so there will be space between the breathable membrane and the insulation. This will also help make the inside of your shed warmer.
  • Next attach the fibre glass wool insulation to the extra baton. Try not to compress the insulation when tacking it to your shed.
  • You can then line the inside of your shed with MDF, plaster board or solid sheet wood. This will then leave a flat, smooth surface which can be painted.

Which shed do I buy?

If you haven’t brought a shed yet and you are thinking of using it all year round then rather than insulating a cheap shed then it might be worthwhile getting a head start and purchasing a tongue and groove shed as this will not only provide more insulation as standrad that an overlap shed, but will also be more durable and watertight. This is also the recommended cladding if you are looking to upgrade your shed.
