Benefits of Spray Foam Insulation for Your Home

Insulation is a crucial aspect of any structure, it fundamentally minimizes noise from outside , and it holds a steady temperature in the climate of the building. When choosing which type of insulation to use, contractors have a number of different options to pick from. Out of all these different insulations, spray foam insulation is quickly and has already taken over the market for residential and commercial jobs.

There are multiple benefits to using spray foam, but one of the best reasons is for it’s high R-value.

R-Value means the insulations thermal resistance, and it’s the numeric measurement of that resistance. The bigger the R-value, then the smaller the heat transfer between that material. There are a few things that the R-value has to do with as far as insulation goes. It’s the weight, thickness and application that the R-value affect. All of these factors have to do with the R-value and they will aid in reducing utilities by up to %30 depending on the R-value.

There are two different types of spray foam insulation

Closed cell and open cell. They each have their purpose, and one isn’t better than the other. It doesn’t matter which type of spray foam you go with. Compared to say fibreglass batt insulation (the more traditional type), either spray foams R-Value will stay integral throughout it’s life compared to fiberglass which losses its R-value, especially if it gets moist. Even during the installation process fiberglass loses it’s R-value, whereas spray foam is created seconds before it is applied and therefore doesn’t lose any of it’s thermal resistant property.

Compared to open cel spray foam insulation, closed cell has a larger R-value per inch, and this allows it to obtain a high R-value in a tighter area, whereas open cell spray foam would need more space to achieve the same R-value.

It’s important to understand that R-value is not the measure of heat transfers in the air, but rather how a specific insulation stops the heat flow. Also realize that having thicker insulation which has a higher R-value isn’t a guarantee that you’ll have a better thermal envelope in your home. Fibreglass as an insulation has an R-value that or only connected to the insulating power, and because of this, you may not achieve that reduction of energy consumption you were expecting. This is why spray foam insulation is the superior insulation and the entire insulation industry is making a shift towards it, some municipalities are actually making it code.
