Understanding R-Value in Insulation R-Value is a scientific measurement and industry standard unit that measures thermal resistance. In essence, an R-Value tells you how insulated an area is, dividing the temperature difference between warmer and cooler areas by heat flux density. Why R-Value Matters for Energy Efficiency R-Value is key in energy efficiency because the higher the R-Value the more insulated an area is. Different [...]

Understanding Spray Foam Drying vs. Curing When trying to determine the length of time it takes for spray foam insulation to dry, it’s important to note the difference between drying and curing, along with which type of spray foam was used. What “Dry to the Touch” Really Means Dry to touch means the spray foam is tack-free, so it can be touched without causing issues [...]

The Short Answer Yes, it’s possible to add spray foam to existing walls. The spray, in its liquid form, can be easily sprayed into a space, where it will expand, fill air pockets, and harden, creating an effective barrier from the elements. However, buildings with old insulation will make the process a little more difficult than those with none at all. This is because insulation [...]
