Insulation Against Metal Siding

Rolled fiberglass insulation generally comes in rolls of 15 inches up to a maximum of 24 inches wide.

Insulation against metal siding.

You can install fiberglass insulation against the metal roof and prevent moisture problems if you cover it with a vapor barrier. Some homeowners choose to use unfaced fiberglass insulation batts. Many homeowners don t find out just how poor an insulator metal siding can be until after it s installed as well at which time it s difficult to remedy the situation. The stud spacing on our metal buildings are typically 4 or 5 foot on center.

A second option for insulating a wall with no sheathing is to use spray foam. Metal siding and insulation do not go hand in hand and you do have a choice on the matter. A newer option we like from ecofoil is their double bubble wrap roll insulation for metal buildings. Each layer is composed of polyethylene bubbles that function as an additional thermal barrier that helps stop condensation.

Metal siding does not have insulating properties. Adding insulation behind the steel siding also adds even more the considerable expense and installation issues surrounding the material. Make a better choice for your home. However if the metal siding is just in a garage where you store your car the effort it would take to install insulation may not be worth it.

Taping the insulation together to achieve the on center coverage isn t best option either. This would require using two or two and a half strips between each stud.
