When it comes to improving your home’s energy efficiency, loft insulation is one of the most cost-effective upgrades you can make. In fact, around a quarter of the heat in an uninsulated home is lost through the roof. That means the right insulation not only keeps you warm but also saves money on energy bills and reduces your carbon footprint. However, with so many different types available, the real question is: which type of loft insulation is best for your home?

What are the different types of loft insulation?  

Blanket insulation – the most popular choice 

For most homeowners, blanket insulation (also called quilt insulation) is the go-to option. Made from mineral wool, fibreglass, or sheep’s wool, it comes in rolls and is easy to lay between joists. It’s relatively affordable, straightforward to install, and widely available. The downside? It can be bulky to work with in tight spaces, and mineral wool can irritate if not handled carefully. It is the best option for standard lofts with easy access. 

Loose-fill insulation – flexible but messy 

Loose-fill insulation is made from lightweight materials, such as cellulose, cork granules, or mineral wool. It’s poured between joists, making it ideal for topping up existing insulation or filling awkward gaps. However, because it’s lightweight, it can easily be disturbed by draughts and may settle over time, reducing its effectiveness. They are best for lofts with irregular joists or areas where rolls won’t fit. 

Sheet insulation – rigid and efficient 

If you’re planning to convert your loft into a living space, sheet insulation (rigid boards made from materials such as polystyrene or polyurethane) may be the best option. These boards provide excellent thermal resistance and can be installed between or under rafters. They also add strength and a smooth surface for further finishing. The trade-off is that they’re more expensive than other types and require careful fitting. They are best for loft conversions or when space-saving insulation is needed. 

Blown-fibre insulation – quick but professional only 

Blown-fibre insulation involves a professional installer using specialist equipment to blow mineral wool, cellulose, or other fibres into the loft. It’s a fast and effective method, particularly for hard-to-reach spaces. However, it’s not a DIY option and tends to be pricier due to the labour costs involved. It is best for lofts with limited access or hard-to-reach areas. 

Which is the best option? 

The “best” loft insulation depends on your home, budget, and plans for the loft. For most households, blanket insulation is the most practical and affordable option. If you’re considering a loft conversion, sheet insulation is a better long-term investment. For difficult spaces, loose-fill or blown fibre provides flexible solutions. 

Loft insulation isn’t one-size-fits-all. The key is to weigh up cost, ease of installation, and long-term efficiency. If you’re unsure, it’s always worth consulting an energy assessor or insulation professional, who can recommend the best solution tailored to your home.
