Wooden sheds often house valuable tools, equipment, and materials. Proper insulation protects these items from moisture and temperature fluctuations, extending their lifespan and reducing the risk of damage.


Start Insulation with the Floor Of Your Wooden Shed

There are two steps in installing the insulation on the flooring of your wooden shed. The first one is insulating the soil during shed construction, and the next one is after.

Soil insulation during Shed construction

During shed fabrication,  you can start to insulate the flooring where it will be installed. Provide enough elevation by either installing beams, or better yet, a certain type of cinder block called breeze blocks. Install them on the top of the concrete. 

It’s also recommended to insulate the concrete slab especially when it is bigger than your wooden shed. 

If the previous method is what you prefer,  use polystyrene plates to insulate the wooden shed’s flooring. Extruded polystyrene (XPS) or Expanded polystyrene (PSE) is popularly used because of its insulation properties.

Insulating a Wooden Shed Cheaply

Insulating a wooden shed on a tight budget is not only possible but also a practical way to enhance its comfort and energy efficiency.
Two cost-effective materials that can do wonders for insulation are aluminum baking foil and bubble wrap. By following a straightforward process, you can create an insulated shed that effectively retains temperature without breaking the bank.

To start, attach aluminum baking foil to the walls using a hammer stapler. This step is crucial as it prevents the wood from sweating when in direct contact with the bubble wrap insulation. Secure the foil in place by stapling it between the wooden framing of the shed until all walls are covered.

Next, apply the bubble wrap in the same manner as the foil. It provides an additional layer of insulation and further improves the shed’s ability to maintain a comfortable temperature.

Not only does the aluminum baking foil create a barrier between the wood and the bubble wrap, but it also acts as an excellent insulation material itself. This combination of materials ensures that your shed is well-insulated and energy-efficient, all while staying within your budget.
