What You Need to Know Before Insulating Your Attic
Proper attic insulation can help you save 10% to 50% of your heating bill according to the Department of Energy. Without adequate insulation, the warm air generated by your heating system will just rise and escape through the roof. Here are some of the things you need to know before beginning your attic insulation project.
R-Value
R-value is the thermal resistance or the resistance to conductive heat flow. The higher the R-value, the better the insulation. Different types of insulating materials have different R-values. The thickness and density of the material will also affect its R-value. The R-value you need for your home depends on your climate and location. The minimum insulation requirement for Michigan is R-49 for uninsulated attics.
Choosing the insulation type and material
Batts
This insulation material is packaged in rolls and comes in different thicknesses and widths. Batts can be made out of fiberglass, cellulose, mineral wool, or cotton.
Blow-in insulations
Also known as loose-fill, this type of insulation consists of small particles of fiber or other materials that are blown into the ceiling floor using special machinery. The common materials used for blown-in insulation are fiberglass and cellulose.
Insulation and roofing companies prefer blown-in insulation because it provides full coverage and superior insulation.
Preparation Before Insulation
Seal air leaks
To make the most out of your insulation, be sure that you seal gaps around attic windows, pipes, and exhaust fans with proper sealants.
Fix roof leaks
Call your trusted roofing company to fix any leaks on your roof as water can ruin your insulation.
Box out light fixtures
Use metal flashing or scrap plywood to create a safety gap of at least three inches for all light fixtures to prevent fires.
