Under floor spray foam insulation.

Does any one know if it is possible to insulate underneath a wood floor using spray foam and if so where can the materials and equipment required for application be obtained.

I can easily get under the floor but would not be able to get very large pieces of Kingspan type insulation down there, hence the query about spray foam. Any advice regarding this would be appreciated, also would it be better to have a company do it instead of DIY.

Contact a foam spray to underside of roof company and ask for quote.
