To prevent heat escaping through the attic and the walls of a home fiberglass batts have been a traditional insulation. New advances in insulation offer a better solution that is easy to install and on the budget.
The contemporary best practice is expanding spray foam insulation installation. Foam fills the cavities in between the framing studs of the walls and attic. Spray-on foam expands to fills in air gaps, unlike standard fiberglass insulation, which lets air pass through and around it. Even as a house expands and contracts the foam insulation expands and compresses with it. This prevents warm air from escaping through cracks and spaces.
Spray Insulation is worth looking into for many reasons, even if it’s not always the ideal solution. Although it is more likely to be the best option for new construction, its features also serve the needs of many existing homeowners who are adding to or trying to improve their homes.
For example, even if the spraying must be done by professionals, and therefore is more costly than other options, the high R-value of spray insulation can make it cost- effective over time, through lower heating bills. In very cold or hot climates this advantage may be well worth the cost.
Spray insulation also carries the advantage of filling uneven areas well. The sprayed foam expands to fill cracks and fit into irregular spaces that would be difficult to work around with other kinds of insulation. The do-it-yourself handyman might be very relieved not to have to work in difficult nooks and crannies, and to just let expansion of the foam do the work.
Another advantage is that spray insulation adheres well to the surface onto which it is sprayed. If a house is being expanded upward, to a second story, then spray insulation under the new floor will be securely in place and offer good insulation for years. It might be a better solution than trying to attach other forms of insulation in such a space.
There are several manufacturers of expanding foam insulation who offer various products for the do-it-yourself handyman and small contractor. You might have a small insulation job that does not require the services of a large insulation installer.
There are different products for different purposes. It is important to find the matching product for your job. These products generally come in handy-sized packs or cans and are easy to use.
