Frequently Asked Questions

Can I insulate my loft myself?

If your loft is easy to access and has no damp or condensation problems, it should be easy to insulate – and in many cases, it is possible to do it yourself. If access is easy and your loft joists are regular, you can use rolls of mineral wool insulation.

Can you put too much insulation in the loft?

Yes, you can. If insulation is installed too thickly or packed too tightly into the loft, it can block air flow and prevent moisture from escaping. This can lead to condensation and dampness. To combat this, make sure to leave ample breathability room for your insulation.

How long does loft insulation last?

Loft insulation is an extremely long-lasting product. If it isn’t damaged, good-quality loft insulation can last up to 100 years.
