Insulation under wooden floor on a concrete block and beam floor.

[smaug]

My lounge has a void (about a meter high) underneath it from which I can see seven inches of block between seven inch wide concrete beams. The beams protrude a couple of inches down below the bottom of the blocks.

I wish to insulate it and would appreciate advice on what material is best for this purpose.

Also how can I best attach it to the concrete and should I only insulate the blocks or should I apply the insulation under the beams trapping an airspace under the blocks?

Any advice would be appreciated

How the fudge do you intend accessing/working under the floor? Is there no room above the B&B floor?

There are double doors into the void and its is directly below the lounge. Working underneath will no doubt be uncomfortable but by no means impossible.

How deep is the void then?

Dare I say it, spray foam insulation?
