What are Possible Problems of Spray Foam Insulation and How Can They be Repaired?

When installed correctly, spray foam insulation Newmarket provides homes and offices with comfort and energy efficiency. Moreover, it outperforms most other types of insulation used in modern buildings.

Unfortunately, it isn’t always applied properly. Up until a few years ago, the equipment itself was the problem. Today, however, the problems tend to lie more with the installation process itself. Human error is more often than not to blame for current troubleshooting associated with spray foam insulation.

This is why it’s extremely important for you to not only acquire the services of professional installers who have a good reputation, but to know how to identify possible problems yourself.

Here are some of the possible problems.

Incorrect Thickness

Foam insulation needs to be applied at an exact thickness in order to work properly. To meet energy code requirements, a specific thickness needs to be sprayed in the appropriate areas. Installers tend to spray a bit more thickness in rooflines than in walls.

Since open cell foam typically fills the framing cavity entirely, it’s easy to tell if the right amount has been sprayed. With closed cell foam, regular spot checking in different places is required since it does not fill the cavity entirely.

If spray foam isn’t the right thickness, it can be either too brittle or too spongy. It’s not uncommon for foam insulation to be installed too thin. If this occurs, you should have the problem fixed prior to covering the foam up.

The foam insulation contracts and pulls away from its application.

Cured insulation can contract and pull away from its framing studs and leave large gaps. This can be caused by a number of reasons: extremely high temperature, bad mixing, bad chemical batch, incorrect spraying, etc.

Unfortunately, this does not always happen right away. It may take a few days or even a few weeks to start noticing the problem. The only way to prevent this is to – once again – make sure you hire the right contractor who understands the physical properties for the different types of spray polyurethane foam.

Some of the air leakage sites are missed.

One of the primary reasons people invest in foam insulation is its air-sealing capability. If one or more of the air leakage spots are missed, the investment is just a waste of money. The areas on which the foam is to be sprayed should be looked over very carefully. All of the cracks and gaps need to be noted and filled accordingly. The best way to prevent this problem is to not rush through the process.

Adhesion problems.

Adhesion errors tend to happen with closed cell foam. The problem areas are easy to find, as all it takes is some random pounding on the insulation. The cause of the problem could be incorrect application, delimitation, or a combination of both. Weak spots have a hollow sound and slight compress.

Repairing Incorrect Foam Insulation

It’s ideal that every spray foam installation be inspected shortly after the application process. Inspection services are worth the investment since they can potentially save you a lot of money, due to the fact that most problems are not difficult to deal with, yet not dealing with them can cause more problems in the long run.

Problems such as cracking usually only affect a small area, which means that repairs can be made without having to completely tear out and redoing the existing insulation.
