Which Part of the House Needs the Most Insulation?

The part of the house that needs the most insulation is the attic. This is because heat naturally rises, so the attic is a major source of heat loss in the winter and heat gain in the summer. Insulating the attic can significantly reduce your energy bills and make your home more comfortable. But how much Insulation should you put in your attic?

Over Insulating the Attic

Insulation has an R-value that refers to how well it resists heat transfer or heat flow. Over-insulating your attic or using the wrong type of insulation can increase costs, provide little or no benefit and possibly create larger problems. Excess insulation in the attic can make a house too tightly sealed and block vents. If airflow is blocked, moisture can't escape. If moisture accumulates in the attic and encounters warm air, that can allow mold to grow, which can result in serious respiratory problems in certain people.

R-Value for Attic Insulation

The higher the R-value, the better the insulation. The recommended level for most attics in Connecticut is to insulate to R-38 to R-49 value for existing homes, which is about 10 -14 inches of insulation. This thickness and the type of insulation will also affect its effectiveness. Some insulations are better suited for certain areas and the experience team at Koala Insulation of Central CT will guide you through your attic insulation process as there are many options to choose. There are also many safety precautions that professionals must take during installation that homeowners may not understand or may simply not have the equipment for.
