Can I use pitched roof insulation under floors?

dagoof · 24 Jan 2009

I bought a load of 75mm Kingspan TP10 for insulating my pitched roof but have found I've got quite a lot left over - I was wondering if this would be suitable to insulate under the ground floor of a bungalow?

The reason I ask was because I thought there may be some breathability needed

It will be ok to use it. On new builds nowadays it is specified to insulate between the joists so go for it.
