Whether you’re considering replacing the insulation you have in your home or weighing your options when building a new home, there are pros and cons to both fiberglass and spray foam insulation. While fiberglass is still the more traditional of the two, spray foam insulation provides a number of benefits. At St. Louis Insulation, we have put together a short guide to provide you with more information about the benefits of spray foam insulation in St. Louis.

More energy efficient

When comparing spray foam insulation to fiberglass, you’re going to get a more energy-efficient option regardless of whether you choose closed cell or open cell foam. The foam creates a tighter seal against your walls and roof than what you get with fiberglass, thereby making your home more airtight. This prevents air from getting in or out and allows your air conditioner or heater to run more efficiently, which could save you hundreds of dollars over the course of several years.

Longer life

Fiberglass insulation is designed to last between 10 and 25 years. You might reach the top-end of that estimate if the insulation is able to stay dry. Should moisture find its way into your insulation, its lifespan will be cut much shorter. On the other hand, spray foam insulation will quite literally last a lifetime as it’s capable of lasting upwards of 80 years. This means that you can have it installed in your home and never have to worry about it again.

Better sound blocking

The concepts that go into sound blocking and energy efficiency are similar in that a tight seal works best. When spray foam insulation is installed, it is applied to the entire segment of the wall. It creates a tight seal that fills in gaps and corners with no surface left uncovered. This is excellent for sound blocking as there are no nooks or crannies that allow for sound waves to permeate through the walls of your home. Fiberglass insulation can only do this so well because it’s applied in sheets. While the fluffy sheets are able to fill the space, there will always be some level of space between the edges and the wall framing.

Better for allergies

Insulation can be damaged and cause problems in your home. Should fiberglass insulation sheets break, fiberglass will fall into the walls and onto the floor. This can cause major skin and breathing issues. If foam insulation breaks and falls away from the wall, you’re likely to have a small problem that can be cleaned up with a vacuum cleaner. Additionally, foam insulation helps to block pollen from making it into your home.

Adds strength to your home

Something that foam insulation does that fiberglass sheets cannot add strength to your home. Spray foam insulation is applied to the inside of your walls and hardens to form a strong seal from the outside air. Once the foam has hardened, it will also help to improve the strength of your walls and roof. This would essentially be like adding an extra layer of drywall inside your walls to help support them. In fact, foam insulation can increase the racking strength of your walls and roof by as much as 250%.
