Put simply, a loft conversion helps you to maximise the use of space in your home. Many homes have existing loft spaces that are left unused, only to store a boiler or some old boxes, but this space can be transformed into a wonderful living area.
When converting your loft, you’ll need to insulate it as well to ensure it’s comfortable, liveable, and does not become a financial burden in the long run. In addition to significant savings on your energy bills, loft conversion insulation will also cut your domestic carbon footprint by a staggering 1 ton a year, benefitting you and the planet at large.

The best insulation for a loft conversion depends on a few factors, such as your budget, personal preferences, and home condition. For a budget-friendly option, consider mineral wool or fibreglass. For thermal efficiency, PIR boards stand out as a great option. For sustainability, cork boards are a wise choice.
There is a range of regulations for loft conversions, not so much for the actual insulation of a loft. You do not need planning permission to insulate your loft, but your loft conversion must follow a series of regulations relating to your property size, scope and volume.
For optimal thermal performance, it is strongly recommended to get at least 270mm of thermal insulation in place for lofts, especially if using mineral wool, fibreglass, or other similar blanket-like insulation materials. Synthetic boards such as PIR have high thermal efficiency and may do with less thickness.
