Which Attic Insulation is the Most Effective?


No matter how large or what material the house is built of, it needs a well-insulated attic to keep the temperature stable and the energy bill down. The last sentence refers to you in bold font and all caps if you live in a country of, especially cold and snowy winters.

But which form of attic insulation is the most effective? There is no “one-size-fits-all” solution for the right insulation since many aspects are involved. Read on to learn what you need to know about the various kinds of attic insulation and how to pick the best one for you.

Any discussion of proper Attic Insulation Ajax must begin with a thorough understanding of R-Value, the metric used to measure insulation strength. The higher the average R-Value of an attic, the better it would be at trapping heat and preventing your house from freezing in the winter or becoming a sauna in the summer.

Insulation Materials for Attics

Though R-Value is a “the higher, the better” measurement, the highest R-Value insulation content isn’t always the right option for your home. Different insulation materials have different strengths and disadvantages, and some attics may be best suited for one form of insulation than another.

Here’s a rundown of the most commonly used insulation materials, together with the benefits that have made them so popular with customers and the drawbacks you should remember before purchasing:

Fiberglass is a type of plastic

Fiberglass insulation is the equivalent of a McDonald’s Big Mac in terms of insulation material: it’s not the best one, but it’s by far the most common. In the case of specially made high-density fiberglass, the R-Value will vary from 2.2 to 4.3.

Cellulose insulation is usually made of wood or recycled paper, and it is often advertised as a green commodity. Despite having significantly more recycled material than other forms of insulation, cellulose does not pass a comprehensive “green” review of its environmental effects.

There are a few disadvantages to cellulose insulation that you should be mindful of. Cellulose insulation is flammable by itself and is treated with anti-flammable chemicals in large quantities. Both cellulose insulation manufacturers are required by the Consumer Product Safety Commission to inform their customers that cellulose insulation is a fire hazard.

Mineral Wool

Mineral wool batts, which are made from molten stone and reclaimed slag from steel mills, are more popular in Canada and Europe but are seeing a revival in the United States.

Mineral wool is more costly than fiberglass, but you get what you pay for because of the following benefits:

In the worst-case scenario of a house fire, this will provide the fire department with valuable, potentially life-saving extra minutes to get on the scene and react. You can checkout Attic Insulation Ajax.

Water Fighter – Mineral wool is not only fire-resistant, but it is also water-resistant, allowing it to continue insulating even in the case of the greatest moisture leak.

Mineral wool acts as a sound barrier, effectively preventing outside sounds from approaching your house.Mineral wool insulation has only one downside, but it’s a big one: inhaling it when it’s being installed will cause cancer. If you’re present during the insulation installation, proceed with great caution.
