Your Guide to Better Shed Insulation
Posted: October 18, 2019
Why Insulate Your Shed?
Shed insulation is essential if you’re going to make the most of your garden shed. The temperature inside can get pretty cold during the winter months so, if you want a pleasant working environment the whole year round, you’re going to need a well-insulated shed.
In order to achieve this, you have two options: insulate your existing shed or buy a new one that offers better levels of insulation.
Insulating an Existing Shed
Inspect Your Shed
Firstly, clear out the shed completely. You don’t want your work impeded by tools, garden furniture and bikes.
Ensure that there are no loose panels, no missing fixings and that everything is secure, well-maintained and watertight.
Next, check the condition of the roof felt. If any of the corners are loose then nail them to the roof. If its overall condition is poor then you’ll need to consider replacing it with a new weatherproof covering.
Once you’re satisfied that everything is ship-shape, it’s time for some proper shed insulation.
Insulate Doors and Windows
Pay careful attention to the areas around the doors and window frames. This is where a lot of your shed’s heat is lost.
Fill any cracks or holes, caused by general wear and tear, with liquid wood or expanding foam. Then use draught excluders, or even homemade rubber strips, around the doors and window frames to plug further gaps.
Insulating the Walls and Roof
Firstly, fit a damp-proof membrane on your shed’s inner cladding.
Then it’s time to select an insulation material to place between your shed’s structural frames.
Polythene and Bubble Wrap
The cheapest and easiest option is to use polythene or bubble wrap. However, bear in mind that it is also the least effective.
PIR Insulation Boards
Fitting PIR insulation boards is a costlier, but far better option. This is a method commonly used in the building trade, so you won’t have any problems finding boards to fit between your shed’s frame. Cut them to size, if necessary, and then simply push them into place.
Packing rockwool between your shed’s frames is another highly-effective method of insulation. Ensure that you wear protective glasses, a facemask and gloves, when cutting it, to avoid irritation to your eyes and skin.
If this puts you off, why not use a different type of wool? Consider Thermafleece, which is purpose-made for this type of job.
Finally, it’s time to board up the insulated layer. Plywood is the most effective material to use, as it is tougher and more water-resistant than plasterboard.
Alternatively, you could always use some old pallets. Remove the nails, sand them down, then stain or paint, according to taste.
Insulating the Floor
The obvious way to insulate a floor is to roll out some old carpet, preferably over a water-resistant membrane.
If you don’t have any to hand, many carpet retailers sell off-cuts for a reasonable price.
If you’re willing to accept a slight reduction in the height of your shed, you could even add a second, false floor.
A layer of Styrofoam, with plywood on top, works nicely.
Buying A Better Insulated Shed
The Benefits of Tongue and Groove
If you don’t enjoy DIY and are simply in the market for a new shed, choose one with tongue and groove cladding for the best insulation.
Tongue and groove sheds are built from thick, interlocking boards, which leave no gaps, whatsoever, in the walls, floor or roof. This ensures superior levels of weathertightness and insulation.
