What is the Best Type of Attic Insulation for Your Home?

If you're looking to make a positive impact on the environment, fiberglass block insulation is likely the best option for your attic. This type of insulation is made from recycled sand and glass, making it lightweight and flame-resistant. It's also the most common type of attic insulation. Blown fiberglass insulation is another great choice for insulating your attic.

But why? What are the benefits of this type of insulation? Blown fiberglass insulation offers many advantages, but what about the downsides? The next type of attic insulation on our list is blown cellulose. The last type of attic insulation is spray foam insulation. This type of insulation is becoming increasingly popular due to its extensive benefits. Unlike other types of attic insulation, spray foam insulation comes in liquid form.

When it comes to determining whether R30 insulation is good for an attic, there is no one-size-fits-all answer. The answer depends on many factors, including climate, geographical region, and the specific characteristics of the attic space.

Generally speaking, however, R30 insulation is a good choice for attics in most climates. It provides a high level of insulation that can help keep the attic space cool in summer and warm in winter. Most block insulation consists of fiberglass or mineral wool, sometimes denim. Blown insulation also known as loose fill insulation comes in small pieces packed in large bags and requires a blowing machine to fill the necessary spaces.

Fiberglass, cotton, and mineral wool can all be used as loose fill insulating materials, but fiberglass is the best choice for blown insulation. Unlike block insulation, blown fiberglass insulation is perfect for filling tight gaps around wiring, pipes, or any area with an awkward structure. In general, if your attic measures less than about 10 to 13 inches (the equivalent of an R-30), it's recommended to add more insulation. However, the recommended level of attic insulation varies depending on where you live and how old your home is.

For reliable attic insulation that's easy to install and can be cut if necessary, Owens Corning R-38 fiberglass insulation comes with more than four packages for large attics and is made from 35 percent recycled materials. Insulation in the form of a blanket is an inexpensive and easy way to install insulation on the attic floor and wall. Often combined with an insulating blanket to seal gaps, it's one of the most effective ways to isolate the attic space. Foam plate insulation is rigid and lightweight, making it easy to transport and install on floors, walls, ceilings, and around windows.

So it's clear that you need to invest time and money into insulating your home - but what types of attic insulators are available? Which one is better? And what are the potential risks associated with each? You don't necessarily need to remove old attic insulation before adding new - unless it's damp or made from hazardous materials (such as asbestos) or simply degrades too quickly to serve any other purpose. The market for insulation products includes block insulation, blanket-shaped insulation, rigid foam insulation, blown insulation, and loose-fill insulation. No matter how big your house is or what material it's made from - each one must have adequate attic insulation to keep the temperature regulated and energy bills low. These options are made with fiberglass, cotton, cellulose, polyester, polyethylene, and polystyrene - all of which are easy to install and suitable for cutting or adjusting as needed.

Whether you spray it or choose to blow it - this type of insulation is easy to apply over existing insulation or on its own - reducing heating and cooling costs by 20 percent. If you need to replace the blocks' existing insulation - you'll need to know how to remove them - or you can contact an attic services professional to do the work for you. A widely publicized study conducted by Oak Ridge Laboratories in 1991 found that loosely filled fiberglass attic insulation lost much of its insulating value once temperatures dropped below 20 degrees - making it an inferior product compared to cellulose. This type of insulation is easy to cut with a utility knife or scissors - and easy to install with staples, nails or an adhesive.

Affordable and effective - Frost King's natural cotton attic blanket measures 16 x 48 inches thick and 1 inch thick - conveniently - most blowing options can be applied over existing insulation - filling gaps between existing wall posts and ceiling beams - increasing overall efficiency.
