The attic insulation is a crucial component of your home’s energy efficiency, regulating temperature and lowering utility bills. The type of insulation you choose should be based on your needs, regional climate and budget. There are many types of attic insulation, each with its own benefits and drawbacks. Choosing the right attic insulation is important because a high R-value ensures better resistance to heat, and ultimately lowers your heating and cooling costs.

In the past, builders and homeowners had numerous options for attic insulation, including Mineral Wool, Fiberglass, Rock Wool, Vermiculite, Cellulose and others. But stricter building codes and safety regulations have narrowed the choice to two safe, cost-effective and long-lasting attic insulation materials – Cellulose and Fiberglass.

Loose-fill or blown in insulation is comprised of small particles of either cellulose (made from recycled newspaper), fiberglass or mineral (rock or slag) wool, and installed with a blowing machine that shoots the material into the attic space. The material fills gaps and spaces more effectively than blanket or batt insulation, and can be adjusted for depth and density to achieve your desired R-value. Blown in insulation is also moisture-resistant, which prevents mold and mildew growth and rot, and can be quickly installed by professionals.

The only downside is that blown in insulation can settle over time, which can lower its R-value. It is also prone to absorbing moisture, which reduces its effectiveness. It is also a more expensive option, but offers significant savings over the long run.
