Spray foam Attic insulation Pros and Cons

To give you a brief explanation, we’re ready to walk you through the pros and cons as stated below:

The Pros

  1. Such An Easy Insulation

Speaking of spray foam insulation, you will not have to worry about the installation. It’s highly well-known as one of the easiest insulation to install, even in an uneven surface. You only need to spray the foam on the chosen area. Then, this foam will dry out in a day and is highly resistant.

  1. Eco-friendly

Go green or eco-friendly materials are in high demand these days. The chemicals inside, typically in closed-cell or open-cell spray foam, are materials that expand and harden, forming an effective insulation material.

The minimum materials used in the foam make the spray foam insulation able to reduce your energy consumption. In other words, this type of insulation also has the potential to be more eco-friendly.

  1. Prevent Bugs and Mold Growing

As the sprayed polyurethane foam fills in the gaps or small cracks in your attics, it effectively closes off entry points for bugs and mold, improving indoor air quality. On the other hand, the closed cell will reduce the water that can get in between the attics. Hence, the production of mold is getting smaller.

The Cons

Speaking of the cons, certain ways could go wrong if the spray foam insulation is not installed properly, here there are:

  1. You Pick The Bad Quality

No matter how easy and effective it is, it won’t work out if you pick the bad quality of spray foam insulation. The poor spray foam still creates cold spaces between the attics. So, you need to ensure when purchasing the spray foam insulation.

  1. Wrong Place

Having a dream loft means providing enough space and must be measured carefully. You must get the insulation extension at least 20% of the height between your roof and the floor. If these needs aren’t met, you won’t be able to get inside the loft comfortably. So, be more careful where not to use the spray foam insulation.

  1. Choosing The Wrong Type of Spray Foam Insulation

Just like picking the wrong place, the incorrect type of spray foam insulation can cost you later. You have to do a little digging on the amazing advantages each spray foam insulation gives. That way, you can choose the right ones for your loft.

  1. Cold Air Leakage

As it’s named, spray foam insulation can’t protect some areas from air leakage where it’s not sprayed. Though this insulation is well known for its ability to withstand cold air-sealing, the determination is in your hands. It’s about how careful you are not to miss a single gap and how you understand the building structure of your house.

Even if spray foam insulation is highly common, it doesn’t mean that it’s a total winner. No matter what brand of spray foam insulation you choose, you need to do proper planning before installing and doing it properly. When the installation is done correctly, it will even help the structure of your house survive hurricanes.

Additionally, while spray foam insulation can significantly improve energy efficiency, improper installation can lead to gaps and incomplete coverage, undermining its effectiveness. Therefore, it’s essential to ensure that the installation is carried out meticulously to avoid any potential issues.”

So if you’re thinking about insulating, you should consider the problems with spray foam insulation in attics. Make sure you choose the right type and pick the right place to avoid any problems in the future.
