A Guide to Shed Insulation

A Guide to Shed Insulation
Posted in: Guides, Insulation

Insulating your shed can be extremely beneficial to extend the time you can spend in it throughout the year, as well as protecting your belongings and electronics from extreme temperature changes.


Seemingly simple garden sheds on the outside are now being transformed on the inside into micro homes for people to retreat to and spend their time relaxing, creating, reading and more. With a little insulation, you can enjoy your shed come rain or shine and utilise it fully no matter the season.




Should you insulate a shed?

If you need outdoor storage all year round or just like to be in your shed to practice a hobby, insulation can be very effective and inexpensive. Not only will it help to prolong the equipment and tools you store away, it can also be a place you can store delicate plants in harsh conditions. It is worth noting that not all sheds are suitable for insulation. Metal and plastic sheds are not designed to be insulated, however most types of standard wooden sheds can be insulated to retain heat in the colder months.


What are the benefits of insulating a shed?


  • Regulate temperature

An insulated shed will minimise extreme cold temperatures, severe heat and can even regulate humidity. This will create an ideal environment to store sensitive tools and equipment such as electronics, paint and valuables.

  • All-year-round living space

Insulation will allow you to transform a basic storage unit into a mini retreat, an office shed or place to practice hobbies. It will give you the chance to spend long hours in your shed comfortably no matter the weather conditions.

  • Prolong the life of your shed

Humidity, moisture and extreme temperatures can damage the structure over time, welcoming insects, mould and rotting.


Things you need to know before you insulate your shed


Before you insulate your shed, you need to thoroughly inspect it to make sure it is dry and waterproof. Pay particular attention to gaps in the cladding and the overlaps of roofing or flooring materials. Leaks will compromise the structure and can cause mould and decay, so carrying out this inspection is extremely important.

You also need to check the window and door frames, ensuring they are intact and secure. Double glazed windows are naturally best for optimal insulation.



What’s the best insulation for a shed?


Before you begin you need to decide if you will be adding any electrics or plumbing as this will need to be completed first. You then need to select the correct materials, taking into consideration what you will use it for, how much protection you need and your budget.

Bubble Wrap

This is one of the most basic forms of insulation and is affordable and easy to install to the inner surface of the floor, roof and walls. Euroform U Foil BDA is a more advanced form of insulation including bubble wrap as it is constructed using polyethylene bubble and aluminium to provide thermal resistance, water vapour resistance and more.


Insulation Boards

Multi-purpose insulation boards are a simple solution to providing protection against harsh conditions and temperatures. Available in a range of thicknesses, the boards can be cut to shape and fit to the floor, roof and walls. This type of insulation is commonly used in the construction industry and they come in foil-backed boards of all sizes. Celotex TB4000 Insulation Boards are ideal for a shed.



Rockwool cavity insulation is great for temperature and humidity control, and it is also beneficial if sound insulation is of interest. It can be messy to use, so it’s important to wear protective gloves and glasses when handling, but it is a lightweight and affordable solution.


When insulating your shed, you will also need a sealant and adhesive to fit the insulation and seal around doors and windows that are prone to ingress from water and wind. Rockwool Acoustic Intumescent Sealant. Is a high performance sealant and adhesive that can be used as a waterproof sealant on virtually any material.


How to insulate a shed


  1. Ensure your shed is waterproof and dry

Once you have removed all of your belongings, inspect every corner, windows, the door, roof, floor and walls. There’s no point in insulating a shed that isn’t waterproof as you will only get mould, dampness and potentially rotting wood.


If your window and door frames are damaged, try to remove the rot, fill with wood filler before sanding and painting. It is also advised to regularly treat your shed with wood stain to prevent rotting.


  1. Draught exclusion

Over time, your shed will naturally experience wear and tear which can cause gaps that allow in the wind and rain. Use a sealant as an effective solution to draughts or gaps and fit adhesive rubber draught excluders once set.


  1. Install your insulation

Once you have chosen suitable materials, you need to install the insulation between the structural frames of your shed. It is best to install the materials to the floor, roof and walls if possible for optimal insulation. As with any form of insulation material, make sure to read the manufacturer’s guidelines before installing.


  1. Fit panelling or wall boards

Now that your insulation material is installed, you will need to fit panelling or wall boards to the inside of your shed. There are different options available including plasterboard, hardboard, plywood, pallet-board and more. Once you have covered up the insulation, your shed is now ready to decorate to suit your needs.
