HD Spray Foam is an excellent way to improve the energy efficiency of any building. It seals gaps, cracks, and holes to create a tight building envelope, stopping air movement and heat transfer and improving energy efficiency and comfort. This is particularly important in metal buildings, which tend to be very cold in the winter and sweltering in the summer.
Spray polyurethane (SPF) insulation can be applied to both new and existing construction, including framed, trussed, and post-and-beam homes. It is also a good solution for pier-and-beam homes and rooms over garages that are not well insulated. In addition to lowering energy costs, spray foam can help reduce moisture and mold problems and increase the structural integrity of the building.
Cost Comparison: Spray Foam Insulation vs. Traditional Insulation
There are two primary types of spray foam: open-cell and closed-cell. Open-cell spray foam has a higher R value per inch than closed-cell, and it can be applied to walls, attics, roofs, and other areas of the structure. Closed-cell spray foam is more rigid than open-cell, and it is better suited for roofs or other exterior applications. Both types of spray foam use hydrofluorocarbons as blowing agents. These chemicals have a global warming potential (GWP) of over 3,400, which is almost as bad as carbon dioxide on a per-kilo basis.
Homeowners can purchase DIY kits to install their own spray foam, but it is difficult for non-professionals to get a great result. The process requires specialized equipment and is highly complex. If done incorrectly, it can lead to dangerous chemical off-gassing and subpar performance. In addition, the process is messy and the chemicals are abrasive to skin, eyes, nose, and mouth. Proper attire is also needed, and a respirator is recommended.
