One question we are always asked is what is the best insulation for your home? Is it batt, loose fill rigid or spray foam? Each type of insulation works a little bit differently depending on the insulation project. However, one type of insulation that is best for any type of insulation project is closed-cell spray foam.
What’s the difference between open-cell and closed-cell insulation?
When we talk about open-cell and closed-cell insulation it has to do with any air cells that are left after the insulation is installed. With traditional types of insulation, these are almost always open-cell as there will be air pockets left.
With spray foam, there is also open-cell insulation. In this case, there are small air pockets left by the foam which reduces its R-value – the ability to resist heat loss.
With closed-cell insulation the spray foam is much denser, meaning the foam is more solid and compacted. As such, it makes the spray foam insulation very solid, almost as hard as a rock, which also increases the R-value.
Is the extra cost for closed-cell spray foam worth it?
Absolutely! The higher the R-value, the better your home is insulated. This translates to lower energy bills. In the long run, your upfront investment will pay for itself in a short period with reduced energy bills and paying for itself. After that, you will be putting extra money into your pocket month after month.
How is closed-cell spray foam more efficient than traditional types of insulation?
It is all about science and the effects of moisture in the air with temperature changes. In the summer, when it is hot outside, any air pockets in the walls and attic also become hot. Warmer air also contains more humidity, which can become moisture when the air is cooled.
When moisture soaks into traditional types of insulation, it loses any insulating properties. Instead, the insulation acts as a conductor for air movement and heat loss. With closed-cell spray foam, it creates an air barrier, which in turn, creates a moisture barrier to keep your home sealed better and prevent heat loss.
Not to mention, it won’t absorb moisture, so it never loses its R-value. Additionally, spray foam is mold and mildew resistant because it doesn’t retain moisture!
Does closed-cell spray foam deteriorate over time?
Closed-cell spray foam is made of inorganic materials, which means it does not deteriorate or degrade like some other types of insulation. For example, batt insulation has a paper backing that can degrade. Batt insulation can also sag with age and sink inside the walls, leaving open gaps without any insulation at the top of the walls in your home.
Is installing closed-cell spray foam a DIY project?
If you want to ensure your home is properly sealed correctly, then you need to hire a professional. Attempting to do this type of project yourself can result in a wide range of problems and issues, that quite often result in us getting a phone call later.
