Which side of insulation foam faces out?

Does the reflective side of insulation go in or out?

Foil insulation underlayment is recommended under a metal roof, and in most cases, the shiny side should be facing up, but there’s a catch. Foil insulation is a radiant barrier, and it works by reflecting heat from the metal, but for it to do its job, there has to be a layer of air between the roofing and the foil.

3. Proceed “down” stapling to the side of the stud every 2″- 3”.
4. Repeat procedure on opposite stud.

Does reflective insulation really work?

Some studies show that radiant barriers can reduce cooling costs 5\% to 10\% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it’s usually more cost-effective to install more thermal insulation than to add a radiant barrier.

How good is reflective insulation?

Reflective insulation can block 95\% of radiant heat and provides superior thermal performance. Reflective insulation reflects escaping heat back in the direction of your home’s interior. By harnessing the loss it lowers your heating bills.
