HD Spray Foam is an extremely versatile insulation material that can be used to insulate a wide variety of structures. It is applied on site as a liquid, and it expands when it comes into contact with air. This allows it to fill gaps, cracks and crevices where air commonly escapes from homes, buildings and commercial structures. The foam also conforms to the unique design of a structure, creating a tight building envelope and improving energy efficiency.
Benefits of Using Spray Foam Insulation
The process of applying spray foam insulation begins by removing any existing insulation from the area to be sprayed. This can be difficult in older homes, but it should be done before the crew starts working. A crew will then run a hose to the area being sprayed and begin mixing the chemicals that create the polyurethane foam that will insulate the space. The chemicals are kept in separate hoppers, and they are mixed together at the tip of a spray gun. Once they are mixed, the resulting foam is sprayed into the area and it hardens to form an effective air and vapor barrier.
Some types of spray foam, particularly open-cell, contain high levels of hydrofluorocarbons (HFCs). HFCs have a global warming potential over 3,400 times higher than carbon dioxide on a per kilogram basis, making them very powerful greenhouse gases. For this reason, it is important to choose a spray foam insulation that uses low GWP blowing agents such as BASF Walltite CM01 or Genyk Boreal Nature.
