can i use this to insulate a suspended timber floor?

I have and is working really well. It has made a big difference to what the floor feels like on your feet. I put down two layers and secured them in place with tape.Hope that is of some use.

Does this come with instructions on how to fit and do I need to buy any special glue or other products to use this?

It's really easy to install, there's a front and back. You'll need a stapler and staples to attach it to your trusses / timbers and you'll need foil tape for sealing the joints. I'd advise having a Stanley knife as well.

can you use this on top of a concrete floor and how do you glue it to floor?

I can't say on that as i only used it in the greenhouse to keep the warmth in

Would this trap cold out if we lined our internal garage door?

Metal garage doors can use any type of insulation. An affordable option is fiberglass insulation batts. Insulating a garage door can be even easier with DIY garage door insulation kits. These kits provide pre-cut insulation, fasteners or tape and sometimes tools like gloves and utility knives.
