Loft Insulation
If your office building has been built in the past 100 years, it’s likely that it’s been constructed with two layers of wall, leaving a small space (known as a cavity) between them. The cavity is there to prevent external elements such as rainwater from penetrating through the outer wall to the inside of the property. If left unfilled, however, open loft spaces and cavities are a huge weakness in insulation, potentially being responsible for 1/3 of heat loss from a building!
Most often, cavity insulation comes in the form of mineral wool, beads and granules, as well as polyurethane foam. Cavity insulation fits closely against the brick and block of the wall construction with no sagging or slumping. Its weatherproof properties provide essential protection against bad weather and moisture, which have the potential to lead to structural decay and dampness.
Cavity insulation is a fantastic choice for old buildings looking to improve their thermal efficiency, as well as new builds looking to fulfil optimal energy use.

How to Install Loft Insulation
Installing loft insulation is a straightforward process that can significantly improve the energy efficiency of your building. Whether you’re a DIY enthusiast or a professional installer, here’s a step-by-step guide to installing loft insulation:
- Safety First
Before starting, ensure you have the right safety equipment. Wear a dust mask, goggles, and gloves to protect yourself from insulation fibres. Also, ensure the loft space is well-lit and that you have sturdy boards to walk on.
- Prepare Your Loft Space
Clear the loft of any items and check for any existing damp or ventilation issues. Repair any damages and make sure the loft is dry.
- Measure the Area
Measure the space between the joists and the total area of the loft. This will help you determine how much insulation material you need.
- Choose the Right Insulation
Select the appropriate insulation material for your loft. Our range includes options like glass wool, mineral wool, and eco-friendly sheep’s wool, each providing excellent thermal performance.
- Roll Out the Insulation
Start at the furthest point from the loft hatch and unroll the insulation between the joists. Cut it to size using a sharp knife. Ensure it fits snugly without gaps but avoid compressing the material, as this reduces its effectiveness.
- Layering
If the existing insulation is below the level of the joists, lay a base layer between the joists. Then, add another layer across the joists to achieve the recommended depth (usually around 270mm).
- Insulate Your Loft Hatch
Don’t forget to insulate the loft hatch. Attach a piece of insulation material to the upper side of the hatch to prevent heat from escaping through this area.
- Ventilation
Ensure that any eaves ventilation is not blocked by the insulation. This is crucial to prevent condensation build-up.
- Final Checks
Once you’ve laid all the insulation, double-check for any gaps and ensure the insulation is evenly spread.
- Dispose of Waste Responsibly
Clean up any debris or offcuts and dispose of them responsibly.
