Which Insulation Would Be the Best For My Existing House?


There are many ways to take benefits of government grants for insulation, as we know that every home requires insulation, but when it comes to the use of spray foam, injection, fiberglass, or cellulose, which would be perfect for your home. Before jumping into this, let's understand first why is insulation so important for your home?

Whether it is winter or summer, the insulation is what keeps the air you are paying to heat and cool inside where you want it. It helps to keep the temperature inside consistent without the furnace and air conditioning. Basically, insulation is a material used that reduces heat loss or heat gain by providing a barrier between the inside of your home. And this thing not only helps to keep you warm in the winter but also reduces the energy bills and saves your money. Majorly there are three types of insulation used in homes. Foam, fiberglass, and cellulose. Let's start with the foam insulation.

Foam insulation comes in two different forms: spray and injection form.

Spray foam

It is the process in which the foam is sprayed in an open cavity such as in the construction, attics, crawl spaces, rim joists, and pole barns, in a liquid state. The spray foam then expands and fills the cavity.

Injection foam

In this process, the foam is used to pump into the existing cavity in the wall, which makes it great for insulating existing homes. However, the spray can be either open or closed-cell foam insulation. Talking about the open cell foam insulation, it is very light and flexible due to its composition.

Open-cell foams dry faster, and it is one of the main characteristics of the material, in which the gas inside the cells escapes through the openings in the cell’s wall resulting in foam that is light, flexible, and shifts as it settles.

On the other hand, closed-cell foam spray is much denser and heavier than the composition of open-cell spray. This process creates a denser surface that is far more resistant to weather and temperature change.


Cellulose can be blown in or loose-fill. It works well in existing enclosed walls or open new wall cavities. Cellulose is the oldest type of insulation utilized in not just the attic but also other parts of the house. Cellulose is largely formed of recycled newsprint or denim and can be used as a loose-fill or blown-in material.

In comparison to other insulation materials, cellulose may be a DIY effort and is quite inexpensive when it comes to insulating attics. On the other hand, cellulose can settle by up to 20%, shift to one side of the attic, and do not establish an air seal. This implies that cold and hot air can freely circulate through the attic without being obstructed, resulting in higher monthly expenditures. Along with the insulation, you can also opt for gov grants for storage heaters that make your winter warmer and cozy.
