Insulation Against Metal Siding

This would require using two or two and a half strips between each stud.

Insulation against metal siding. 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. A newer option we like from ecofoil is their double bubble wrap roll insulation for metal buildings. Metal siding and insulation do not go hand in hand and you do have a choice on the matter.

Therefore if you want heat to stay within the area that has metal siding then insulation is necessary. Metal siding does not have insulating properties. Polyurethane foam has the added benefit of sealing air leaks but you shouldn t consider installing it directly against the back of the siding. Some homeowners choose to use unfaced fiberglass insulation batts.

Rolled fiberglass insulation generally comes in rolls of 15 inches up to a maximum of 24 inches wide. Spray foam especially closed cell spray foam will cling tenaciously to siding gluing everything together. Taping the insulation together to achieve the on center coverage isn t best option either. The stud spacing on our metal buildings are typically 4 or 5 foot on center.

You can install fiberglass insulation against the metal roof and prevent moisture problems if you cover it with a vapor barrier. 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.
