When it comes to transforming your steel shed into a comfortable and functional space, proper insulation and wall finishing are essential and are something many Aussies would love to do.

In this guide, we’ll take you through the process of enhancing your steel shed by adding thermal break insulation, Gyprock battens (also known as furring channels), and Gyprock. These steps will not only improve the shed’s thermal performance but also create a polished and finished interior for your steel shed spaces.

Step 1: Adding Thermal Break Insulation

*Why It Matters:*

Adding thermal break insulation is a crucial first step in making your steel shed more energy-efficient and comfortable, especially in varying climates. It helps minimize heat transfer between the steel frame and the interior, making the space warmer in winter and cooler in summer. It’s a win-win no matter the season.

*Materials You’ll Need:*

– Thermal break insulation (e.g., Insulbreak, Insulshed, Thermalbrane, Thermalbreak)

Vapor barrier (if required. Most modern insulations like those we sell also act as a vapour barrier)

– Appropriate fasteners (screws or clips, tape)

*Installation Steps:*

  1. Measure and cut the insulation material to fit between the steel frame members, ensuring a good fit. 
  2. Secure the insulation in place using appropriate fasteners, ensuring there are no gaps that open the back of the insulation to the inside of the shed.
  3. If your climate necessitates it, add a vapour barrier on the warm side of the insulation to control moisture. This would apply if using old-school fibreglass insulation or other blanket-based products.

Step 2: Installing Gyprock Battens (Furring Channels)

*Why It Matters:*

Gyprock battens serve as a structural element that creates an air gap between the insulation and the Gyprock sheets. This gap reduces sound transmission and allows for a smoother Gyprock finish, compensating for any irregularities in the steel frame. It also adds to the insulation properties.

*Materials You’ll Need:*

– Gyprock battens (furring channels)

Self-tapping screws or appropriate fasteners

*Installation Steps:*

  1. Attach the Gyprock battens in a direction that suits your steel frame, ensuring they are level and spaced correctly to suit the size Gyprock sheets you are using.
  2. Secure the battens in place using self-tapping screws or appropriate fasteners. Make sure they are firmly attached to the steel frame.
  3. The battens create a framework onto which the Gyprock sheets will be attached.

Step 3: Applying and Finishing Gyprock

*Why It Matters:*

Now that you have insulation and Gyprock battens in place, it’s time to complete the interior by applying and finishing the Gyprock sheets. This step not only enhances aesthetics but also provides a durable surface.

*Materials You’ll Need:*

– Gyprock sheets (plasterboard)

– Screws for Gyprock

– Gyprock adhesive (optional)

– Joint tape

– Joint compound (Gyprock filler)

Sandpaper (150-grit)

Safety goggles and dust mask

*Installation Steps:*

  1. Measure and cut the Gyprock sheets to fit your shed’s walls and ceiling. Use a utility knife or Gyprock saw for clean edges.
  2. Apply Gyprock adhesive to the back of each sheet if desired, though it’s not always necessary.
  3. Position the Gyprock sheet against the Gyprock battens, ensuring it is level and flush with adjacent sheets.
  4. Use a cordless drill to screw the Gyprock to the Gyprock battens, spacing the screws appropriately.
  5. Cover the seams between Gyprock sheets with joint tape and apply a thin layer of joint compound. Repeat, allowing each layer to dry and sand between coats.
  6. For external corners, install a metal corner bead and apply a joint compound over it.
  7. Sand the surface to achieve a smooth finish.
  8. Finish with priming and painting or applying your desired wall finish.
