What's The Best Type of Loft Insulation for Your Home?
Loft insulation is one of the simplest and most effective upgrades you can make to your home — reducing heat loss, cutting bills, and improving comfort year-round.
But with several insulation types available, it’s not always clear which one suits your property best.
This guide explains the main insulation materials, their pros and cons, and how Snug Lofts helps you choose the right fit for your home and budget.
Blanket (Roll) Insulation – The Popular Choice
This is the most common form of loft insulation, made from mineral wool or fibreglass.
It’s rolled between and across joists to reach the recommended 270mm depth for maximum efficiency.
✅ Pros:
- Cost-effective and widely available
- Quick to install
- Excellent thermal performance
⚠️ Cons:
- Not ideal for very tight spaces
- Can irritate skin if not handled properly
💡 Best for: Most standard lofts with easy access.
Loose-Fill Insulation – Flexible and Fast
Loose-fill insulation is made of lightweight granules that are simply poured or blown between joists.
It’s perfect for topping up existing insulation or reaching awkward corners.
✅ Pros:
- Great for irregular spaces
- Easy to install in small areas
- Can be eco-friendly depending on the material
⚠️ Cons:
- May shift over time
- Not suitable for draughty lofts
💡 Best for: Older homes or hard-to-reach loft areas.
Rigid insulation boards are solid panels that provide high thermal resistance with minimal thickness.
They’re often used when space is limited or for loft conversions where the roof itself needs insulating.
✅ Pros:
- Excellent thermal performance per inch
- Can be used on walls, ceilings, or between rafters
- Long-lasting and durable
⚠️ Cons:
- More expensive than other types
- Requires precise cutting and fitting
💡 Best for: Loft conversions or properties with limited head height.
Blown-In (Loose Fibre) Insulation – Professional Finish
Blown-in insulation involves using a machine to blow loose fibres evenly across the loft floor.
It’s quick, clean, and achieves full coverage without gaps.
✅ Pros:
- Ideal for hard-to-reach areas
- Consistent thickness
- Professional, mess-free installation
⚠️ Cons:
- Specialist equipment needed
- Slightly higher upfront cost
💡 Best for: Larger lofts needing even coverage and minimal disruption.
Many homeowners now prefer sustainable insulation materials made from recycled or renewable sources such as sheep’s wool, hemp, or cellulose.
✅ Pros:
- Environmentally friendly
- Breathable and moisture-resistant
- Excellent acoustic insulation
⚠️ Cons:
- Higher initial cost
- May require professional fitting for best results
💡 Best for: Eco-conscious homeowners looking for sustainable comfort.
- Up to 25% of heat loss escapes through an uninsulated roof
- Loft insulation can save up to £400 per year on energy bills
- It improves comfort and helps your home stay cooler in summer, warmer in winter
- Better insulation can increase your property’s value and EPC rating
