Insulation R-value
The insulation R-value is a measurement of thermal resistance. In other words, R-value tells you how easily heat will move from one side of an object to the other. Even before applying insulation, the materials that make up your home have an R-value. It is not high enough to offer sufficient insulation properties in extreme temperatures like southern Louisiana.
Some insight on Insulation R-value
The solid wood planks that provide the structure of your home offer an R-value of about 1. Your drywall has an R-value of about .45. Even your siding and sheathing have R-values.
However, if you’ve ever been in a home with no insulation at all, it becomes quickly clear that these minuscule measurements of R-value are not sufficient to offer comfort or energy savings. That’s why insulation is necessary.
A variety of insulations exist, each with their own benefits. Fiberglass batting is the cheapest insulation, and it has an insulation R-value of 3.14 per inch. While this isn’t a bad deal, fiberglass batting is susceptible to mold and mildew, air flow and it makes an ideal nesting environment for pests.
Closed cell spray foam is on the other end of the spectrum. Closed cell has an insulation R-value of 7.1 per inch, and it is water-tight and pest-resistant. However, due to closed cell’s 2 Lbs per square inch density, it is more expensive to install.
We don’t recommend closed cell in attics as it would make it impossible to detect leaks if they should occur. Open cell spray foam, which has a density .05 per square inch, is applied in Louisiana attics instead of closed cell. We use 5.5″-7.5″ depending on the application.
Our Pick for Greatest Insulation R-value Value is Cellulose.
Blown-in cellulose insulation offers many of the benefits of costlier insulation at an affordable rate. With an insulation R-value ranging from 3.21 per inch in attics and 3.70 in walls, cellulose insulation provides competitive thermal resistance, and its consistency means that it can fit any nook or cranny. In other words, cellulose insulation provides air sealing as well as insulation.
Made from post-consumer recycled newsprint, homeowners who invest in cellulose insulation can rest assured that they’ve also made the energy-wise decision. In fact, using this highly efficient, eco-friendly insulation qualifies some homeowners for utility rebates.
To increase cellulose’s value even more, the strands are treated to make them more resistant to pests, fires, and mold and mildew. Cellulose works hard for your money.
