What are the benefits of foam board insulation?
Foam board insulation is just like any other type of insulation in that it's there to keep heat in during the winter, and out when it's hot.
The best aspect about foam board insulation is that it is the least expensive type on the market for insulating large walls or ceilings. It can also be applied in smaller sections using spacers, which makes access much easier than with other types of wall assembly. The drawback with low cost foam boards is generally creep creep achieved by additives in the plasticizers they use, making them structurally weaker than higher priced rigid panels used to make regular "rigid" foam boards
Ultimately, however, foam board insulation can be used alone or mixed with regular foam board insulation, providing a good value for the money spent.
Foam board insulation is foam panels used as the primary means of insulating an exterior wall or ceiling structure. It works by trapping air bubbles between foam panels. In this process it increases the R-value of whatever panel it's being used on, thus providing superior insulation to any other type of foam product currently available.
In order to know which foam boards are best for your application, you need to consider a few factors before making a decision: how long will foam board insulation last? What about moisture protection and heat resistance? Will foam boards actually save me money over time? The answers to these questions can help you determine whether foam board insulation is right for your home.
Foam board insulation comes in a variety of types, depending on the foam board manufacturer. You'll find foam boards that are made from various foam panels, which vary by R-value and price. People use foam boards for insulation because they provide superior protection against cold air infiltration, low moisture vapor transmission rates (which keeps walls dry), high thermal resistance, long term stability and ease of installation.
It's important to remember that foam boards insulation is not without its drawbacks.

How does foam board insulation work?
Foam board insulation is primarily used as an underlayment and primarily consists of polystyrene - a 3D foam, or "expanded cellular fluid" that functions similarly to the way glass wool functions. It provides good sound absorption and good thermal properties.
The styrofoam beads of insulation material are blown with air so it expands and creates reinforced holes throughout the board- ultimately creating a foam density between 30 to 90 pounds per cubic foot. The boards can be cut with scissors for more precise measurements since they do not have flat surfaces like sheets of drywall would, similar to a sponge they would conform to any voids in walls or ceiling areas.
Depending on how it is manufactured foam board insulation can either be rigid, semi-rigid or foam.
Foam boards are typically used as underlayment for ceilings and roofs instead of traditional insulation materials like fiberglass or cellulose. Installing foam board underlayment requires the use of special nails that will not split the foam after it has been installed. If you do not use these types of nails foam board insulation may split because the foam is so brittle, which would cause problems later on if it were to rain or snow heavily.
The expanded foam beads store warmth in walls during cold weather conditions and then release that warmth back into the room at a steady rate, which helps maintain an even temperature inside homes during winter months. This makes it a great choice during the colder times of the year, especially in colder climates. The foam board insulation also helps stop outside noise from seeping into walls and rooms to provide a more peaceful environment.
Foam board is available in different thicknesses, with thicker foam boards providing greater thermal resistance and soundproofing qualities.
The higher foam board's R-value (a measure of how well something resists transfer of heat), the better it will resist heat loss from your home when installed properly around windows and doors, studs, electrical outlets and other openings.
