Is loft insulation right for my house?
Loft insulation is ideal for most houses in York. It will keep your home warm in winter and cool in summer, which means you use less energy and save money. If your home has a loft or attic, adding insulation can make it more comfortable.
Energy efficiency:
Loft insulation is energy-efficient as it helps keep your home at a more comfortable temperature. This means you use less energy to heat or cool your home.
Here’s how much CO2 you could save depending on the size of your home:
Your home | CO2 savings (kg/year) |
One-bedroom flat | 410 |
Two-bedroom terraced | 500 |
Detached bungalow | 500 |
Three-bedroom semi-detached | 900 |
Four-bedroom detached | 1,500 |
For a two-bedroom terraced or detached bungalow, that’s the same as boiling the kettle over 12,000 times!

How does loft insulation work?
Loft insulation is like a cosy blanket for your home. It fills the gaps in your loft, so warm air stays inside during winter and hot air stays out in summer. This helps you save money on your energy bills.

How loft insulation works
Loft insulation keeps your home comfortable all year round. It fills the spaces between the beams in your loft, trapping warm air inside during winter and keeping hot air out in summer.
There are three main types of loft insulation:
Blanket insulation: soft rolls or battens are placed between and over the wooden beams in your loft.
Loose-fill insulation: a fluffy material is poured into your loft to fill any gaps between the wooden beams.
What does loft insulation look like and where does it fit in your house?
Think of loft insulation as a soft and fluffy blanket for your attic. It’s usually made from mineral wool, sheep’s wool, or recycled plastic.
This cosy material fills the spaces between and over the wooden beams in your loft. It’s usually around 27 cm thick and can sit between joints that are 40 to 60 cm apart. If your loft is smaller than this, it might be hard to fit the insulation in properly. Our advisers can help you figure out the best option for your home.
