The cheapest way to insulate a shed involves using affordable, readily available materials. Bubble wrap, a common packing material, can be attached to the walls and roof with staples or adhesive, trapping air pockets to minimize heat loss. Similarly, recycled cardboard or newspapers can be stacked between studs and covered with plywood or drywall.
For the floor, inexpensive rugs or carpet remnants provide insulation and comfort. Ultimately, sealing gaps and cracks with caulk or weather-stripping further enhances insulation, making your shed energy-efficient without breaking the bank. I have listed all the cheap ways to insulate a shed below.
Cheap Ways to Insulate a Shed
Insulation is a material that helps keep heat in or out of a building. It’s used to reduce energy transfer through walls, floors, and roofs by slowing down air movement within them. Insulating sheds can help keep your tools dry and safe from extreme temperatures and save you money on your utility bills!
1. Bubble Wrap
Bubble wrap is one of the cheapest ways to insulate a shed. It’s also one of the easiest since you can use it right out of the box without any preparation or special tools.
The big advantage of using bubble wrap is that it’s very effective at keeping heat and cold air out. This makes it ideal for small spaces like sheds, where insulation needs to be compact and efficient. The bubbles act like small pockets of air that help keep heat from escaping through cracks or gaps between boards or panels on your shed’s walls and roof (which could otherwise be let in drafts).
Bubble wrap comes in two different thicknesses: standard and heavy duty (HD). Standard bubble wrap has an R-value* between 1-2 per inch; HD has an R-value between 2-3 per inch–so if you’re looking for maximum efficiency, go with HD! But remember: no matter what kind of bubble wrap you choose–standard or heavy duty–you’ll need several layers before seeing any real results when insulating your shed with this material alone; otherwise, there won’t be enough “pockets” within each layer for them all to do their job properly.”
2. Insulation Roll
Insulation rolls are a great option for insulating your shed. They’re easy to install, and they provide good insulation for the price.
The main disadvantage of insulation rolls is that they can be difficult to cut into smaller pieces if you need them cut down. You may also have trouble finding an exact match in color if you want something other than white or gray (the most common colors).
If you’re using this method, make sure that the roll is long enough so that you don’t have any bare spots on your walls when it’s installed–you’ll want at least 1 foot of overlap per side of your shed!
3. Expanded Polystyrene
Expanded polystyrene is a great way to insulate a shed but it has some downsides.
Expanded polystyrene (EPS) is the most affordable option for insulating your shed. You can find it at home improvement stores like Lowe’s or Home Depot and usually buy it in sheets 4 feet by 8 feet long and 1 inch thick. The sheets come in different colors, so you can paint them to match your shed’s color scheme or make it blend into its environment better!
The main drawback of expanded polystyrene is that it doesn’t hold up well against moisture–it will absorb water from rain or snow very easily if you don’t cover it with something else first. To prevent this problem from happening when using EPS as an insulator for your storage unit, make sure there isn’t any other material touching the outside surface of any wall before applying this type of insulation material onto them; otherwise, they’ll start rotting away pretty quickly!
4. Rigid Insulation Board
A rigid insulation board is a great option for insulating your shed. It’s easy to install and can be cut to fit any shed size, but it has some drawbacks.
First, rigid insulation board is more expensive than other insulation materials.
Second, it will only work with sheds with metal roofs; if you want to use a rigid insulation board on your wood-framed shed, you’ll need to add an additional layer of plywood over the top of your existing roof before installing the rigid insulation board.
Finally (and most importantly), since the rigid insulation board is so thick (about 1/2 inch), there isn’t much room between each layer when installing them. You may need multiple sheets depending on how big or small your shed is!
5. Cellulose
Cellulose insulation is made from recycled paper products and is an eco-friendly option. It can be blown into cavities or applied as a loose-fill material. The dense cellulose packing provides an effective barrier against heat loss and air infiltration. It is also fire-resistant and pest-resistant. A DIY enthusiast can easily install cellulose insulation, making it a budget-friendly option for insulating your shed.
6. Sprayed Foam
Sprayed foam insulation is another cost-effective method for insulating a shed. It consists of two components that, when combined, expand and harden to create an insulating barrier. Sprayed foam fills gaps and voids, providing excellent thermal and air-sealing properties. While it can be more expensive than cellulose, its performance can offset the initial investment in the long run. Applying sprayed foam insulation can be manageable for those with some experience in DIY projects, further reducing costs.
7. Straw
Straw is a natural and sustainable option for insulating a shed. It provides excellent thermal insulation and is an eco-friendly alternative to synthetic materials. Straw bales can be stacked against the shed’s walls, creating a thick insulation layer. Ensure the straw is dry and well-packed to prevent moisture build-up and potential mold growth. Although straw may not be as efficient as cellulose orsprayd foam, it is a low-cost option for those on a tight budget.
