Spray Foam Insulation1- Sound Barrier Many people use spray foam insulation to reduce energy costs in homes and commercial buildings. Adding or increasing insulation in an existing structure can save hundreds of dollars a year on heating and air conditioning bills. Another reason for insulation that is often not considered is noise control. Wall and ceiling insulation can act as a silencer or acoustic barrier to noise from heating and air conditioning systems, telephones, pipes, appliances and radios. It is much more pleasant to work in a quieter working environment than in a noisy one. Studies show that quiet conditions increase a worker's efficiency.2- R ValuesMost existing homes and other structures are filled with fiberglass insulation which is very economical, thus keeping initial construction costs low . It actually ends up costing the owner more, because fiberglass rarely stops air leaks efficiently. Additionally, the material has a low R-value and absorbs moisture, so it is prone to unhealthy mold and mildew. Spray foam insulation will stop air leaks, saving you money on utility bills. It also has a very high R-value of eight for every inch. Fiberglass only has an R-value of one for every inch. 3- Cold Feet I knew there was a lot of heat seeping through my attic and walls. There was too much warm air escaping during the winter and we could never get fully warm on the coldest nights. My brother told me about a better material to use than my old fiberglass insulation. He suggested using spray foam insulation to fill gaps between studs in the walls and attic. Once applied, it expands to over 100 times its original volume, effectively sealing any gaps and cracks to the outside. ......middle of paper......for allergy sufferers. Foam can reduce maintenance and wear on heating and air conditioning equipment. Meets or exceeds building codes and adds strength to the structure. 10- Polyurethane Foam Polyurethane foam is generally used to make spray foam insulation. This is a superior alternative to spun fiberglass sheets used for weatherproofing walls, ceilings and attics. The foam creates a barrier to prevent heat from escaping during the winter and keeps homes much cooler in the summer. Spray foam offers a much better seal, because it can fit into all the little nooks and crannies. It prevents even the smallest drafts thanks to this unique ability to fill small spaces. Foam is available in closed-cell or open-cell types, and the choice depends on the application. The closed cell has a higher R-value but is more expensive than the open cell.
