Insulate your garden shed
For every DIY enthusiast, having an insulated shed is a must. It’s a great way to keep busy all year round and work in a comfortable and warm environment during the winter months.
Whether you use your shed to pursue a hobby, store plants or keep tools and electronics equipment protected from the weather and changes in temperature, shed insulation is an economical and effective way to go about it.
Not all garden sheds are easy to insulate. You can’t insulate a shed made out of metal or plastic. However, if you own a wooden shed, then it can be insulated without too much effort.
One of the added benefits is that it goes a long way in prolonging the structure and lifespan of your garden shed.
Plan your project in advance
Before you begin, inspect the shed to ensure it is waterproof and dry.
Check for any gaps and leaks in the roof and the floor.
Check door frames and windows to make sure they are secure and in good shape.
If your door or window frames are damaged, you need to treat any sign of rot. However, this is a good opportunity to install high specs double glazed windows and doors to avoid compromising the final result.
Choose the Type of Insulation for your shed
Insulation slabs, insulation boards, and bubble wrap foil insulation are among the most common types of insulation material used for this project.
It is great for humidity and temperature control. If you want to maintain good acoustics in your shed, insulation slabs from Rockwool or Knauf will do the trick.
Using slabs is a lightweight and cost-effective insulation for your shed. And is mostly use to insulate the walls of your shed.
As with every fiberglass wool insulation, you will need to wear a mask covering your nose and mouth, protective glasses before starting your work.
To protect your shed against extreme temperatures and harsh weather conditions, multi-purpose insulation boards are another cost-effective and simple solution. They come in a wide range of sizes and thicknesses.
Simply cut the boards to shape and fit the roof, floor, and walls. An ideal candidate for this job would be “Celotex TB4000.”
Bubble Wrap Foil Insulation
A simple form of insulation, but nonetheless a great option to insulate your shed. Bubble wrap is easy to install and extremely cost-effective. Made from polyethylene bubble and aluminum, it provides excellent water vapor and thermal resistance.
Ideally, staple it directly to the wooden frame on the inner surface of the walls, thus leaving an air gap. It is more a radiant barrier than a traditional insulation and works better if air is trapped on either side of it.
Fiberglass is a commonly used insulation for sheds. If your shed has studded walls, then this type of insulation is quick and easy to install.
Once you are done installing the material between the studs, line the walls with plywood or OSB.
Fiberglass rolled insulation is also a great vapor barrier for keeping the level of humidity to a minimum. This is important if you plan to store delicate items.
Sheep Wool Insulation
Sheep wool insulation is one of our favorite options, you can't beat the insulating properties of sheep wool, on top of providing excellent thermal efficiency it also regulates the humidity by absorbing moisture in the air.
Insulate your shed
In most cases, the insulation is installed between your shed’s structural frames. This is usually a simple process that doesn’t require much effort, push and shove the insulation slab in between the joists it all it takes.
After the installation of insulation material, the next step is to fit wallboards or paneling. This fitting is done to the inside of your shed. There is a wide range of options available such as plywood, hardboard, plasterboard, and pallet-board, etc..
DIY Shed Insulation Costs with Foil Insulation
The cost for a small 8’ x 8’ shed is around £350. This includes the roof, floor, and walls of your shed which would require roughly ten sheets of 50mm foil-backed insulation.
For a medium size shed of 10’ x 10’, you need approx. fifteen sheets of 50mm foil-backed insulation, bringing the cost to £525 pounds.
If you want to insulate a larger shed, the estimated cost will be around 840 pounds. If you use any other type of insulation material the price will vary accordingly – depending on the quality of the material.
Don’t forget to consider ventilation and humidity
With an air-tight shed, you will need controlled ventilation to avoid a degradation of the quality of the air inside the shed. This can be done using trickle vents to expel the stale air and draw fresh air in. Controlling the air flow is critical to reduce heat loss.
Similarly, warm air carries moisture, which creates dampness when it gets in contact with a cooler surface. So you need sufficient air circulation to allow the dampness to disperse. Installing sheep wool insulation will also reduce the potential for dampness.
