Overview
• Loft floor boarding involves installing boards over battens or insulation in your loft space to create a robust storage or living area.
• Skill level: 3 / 5 (requires careful measuring, cutting and nailing for a level finish).
• Typical duration: 1 day for an average-size loft with standard boarding.
Safety First
• Ensure secure access to the loft – use a stable ladder or fixed steps and consider non-slip footwear.
• Check the structural capacity of the loft floor before boarding, particularly if planning to store heavy items.
• Wear gloves and eye protection when cutting or nailing boards.
• Ensure battens and boards are securely fixed to prevent accidents.
Tools & Materials
Item | Purpose |
|---|---|
Floorboards (plywood or chipboard) | Surface for storage or conversion, ensuring level support. |
Battens | Provide support and secure fixing points for the boards. |
Insulation boards | Enhance energy efficiency and comfort, if converting a loft. |
Hammer & Nails/ Screws | For securing battens and boards firmly in place. |
Step-by-Step
1. Inspect the loft – check headspace, structural integrity and any existing insulation.
2. Plan the boarding layout – measure the area and mark battens for consistent support.
3. Install battens – fix securely to the joists to provide a level rail for the boards.
4. Lay the boards – position each board on the battens, ensuring a slight gap for expansion.
5. Secure the boards – nail or screw through at regular intervals to prevent movement.
6. Inspect and finish – check for any loose boards or protruding nails and sand down any rough edges.
7. Clean up and ventilate – remove debris and ensure the loft remains well-ventilated.
Completion Checks
• Boards are level, securely attached and free from protruding nails.
• Battens and fixings remain stable with no sagging or movement.
• Adequate headroom and ventilation are maintained in the loft space.
• Final inspection confirms a neat finish and safe boarding.
When to Call a Pro Instead
If there are concerns about load-bearing capacity, existing structural issues or if you are unsure about the safety of the loft conversion, it is best to consult a professional carpenter or structural engineer. This ensures that all measures comply with current building regulations and safety standards.
