The Best Type of Insulation for an Attic

The best kind of insulation for your attic will depend on many factors, such as cost-effectiveness and performance. There are many options in the market, but here is a closer look at why you should opt for cellulose for your attic insulation project.

It has a higher thermal resistance

Thermal resistance is expressed as R-value, and it measures the ability of insulation material to resist heat transfer depending on thickness. When properly installed, cellulose can save you a lot of cash in energy bills. Compared to other materials, including fiberglass, cellulose has the highest R-value.

Protection from air infiltration

When installed in your attic, cellulose will provide a more robust layer against air infiltration than fiberglass or any other material. Air infiltration is where air leaks through holes in the insulation materials and causes heat loss via convection during colder temperatures. The method in which it is installed also has a role to play in cellulose’ high performance. Cellulose is blown into the attic, such that it is able to reach corners and spaces that fiberglass, which is installed in rolls, would not be able to reach, thus creating spaces through which air can flow. Air infiltration lowers the performance of insulation material like fiberglass by up to 40%.

It is the greener option

If you are environment-conscious and want to take a step towards reducing recyclable waste, then go for cellulose. It contains about 80% of recycled wastepaper, which is one of the biggest challenges in waste disposal today. It also takes less energy to manufacture compared to fiberglass, as it takes 750 BTU to prepare one pound of cellulose, and 12,000 BTU to manufacture the same amount of fiberglass. Moreover, using an insulation option that is effective means lower energy consumption in keeping your home warm, thus, a lower carbon footprint.

Increases the resale value of your home

Opting for cellulose insulation may make it easier for you to sell your home at a good price as potential buyers will perceive it as warm and comfortable. Again, they will also prefer it for the significant savings in energy bills.

In addition to the advantages above, cellulose is flame-retardant, has excellent moisture and sound control due to its open-cell structure, and is non-toxic and harmless to pets and children. It does not have asbestos, formalin, or glass fiber, and is, therefore, better suited for your home.
