What is Spray Foam Insulation?

It is a synthetic material created through the combination of organic and inorganic materials. There are different combinations of chemicals that make these materials. One type of material is created on site through a combination of organic resin polyols and isocyonate at specific temperature and pressure conditions. Through a chemical reaction, these two compounds combine to create polyurethane material. This material has the unique property of expanding to a substantially greater size (about 100 times) its actual volume.

This foam hardens in about four hours after application filling out all the space in which it is sprayed and creates a thermal blanket. It can effectively create an insulation barrier when sprayed on to wall cavities, concrete slabs, sheathing interior, drywalls and cavities in walls. It creates a barrier against air flow and moisture build up taking care of insulation as well as mold growth problems. It can strengthen a structure and insulate compact regions which are not normally accessible to conventional foaming techniques. A higher R-value (a measure of thermal resistance of a material) per unit volume qualifies it as an effective insulation material. There are environmental and health concerns raised regarding the toxicity of these materials if directly exposed to them. However if care is taken while installation and environmental exposure is limited through drywall cover, it can be a safe insulation material.
