Increasing Insulation Increase Your Homes Efficiency

Joseph Coupal - Tuesday, January 17, 2012

Making your home perfectly energy efficient can be challenging unless you’re building a custom home right now. Your best bet to energy efficiency now is tightening up the building’s envelope: caulking and weather stripping, more insulation, and better windows and doors.

Plugging air leaks and topping up insulation can save over $400 a year, according to energy provider Direct Energy. Upgrading insulation in a 1,200-square-foot attic saves enough money in energy savings to make up for the cost of the project.

For insulation, anything less than R12 in the walls and basement, R20 for exposed floors and cathedral ceilings and R40 in the attic should be upgraded. Going from R10 to R20 gives you the biggest boost: it’s the first few inches that are most important.

Adding rigid Styrofoam to the outside walls can bridge thermal gaps, which are heat leaks where the fiberglass insulation stops at the studs, although you may need to remove the exterior siding to do so.
