On average heating and cooling comprise 54 of a home s annual utility bills. Types of heat pumps types of dehumidifiers types of generators alternatives to central air conditioning heat loss statistics.

For loose fill insulation each manufacturer must determine the r value of its product at settled density and create coverage charts showing the minimum settled thickness minimum weight per square foot and coverage area per. Once you ve decided which type is best for you examine the material options and prices to home in on the right product. Spray foam offers the best attic insulation performance available.

R value ratings vary among different types and forms of home insulations and among products of the same type and form. Insulation decreases the amount of heat entering from outside when it s hot and traps warmth inside when it s cold. In general an attic s r value should be between r 30 and r 49. R value measures how resistant types of insulation are to heat flow.

For every type and material of insulation check the r value per inch of thickness that the manufacturer has listed. Both can be added to uninsulated attics or layered over existing material. Your home s r value score will guide you toward the type of insulation you need. Insulation is rated by its r value.

They sport insulation values of approximately r 6 5 and r 3 6 per inch respectively. In particularly cold climates you might go up to r 60.

A higher insulation r value usually means a higher price point as well.
