Polyurethane Spray Foam Insulation offer Numerous Advantages over Other Home Insulation Types
By Mark J. Donovan
||Spray foam insulation is an ideal choice for insulating a home. Unlike other types of home insulation products, polyurethane spray foam insulation leaves no gaps or cracks for air infiltration. It also provides a higher R-value (resistance to heat flow) per inch than any other type of house insulation product.
Open Cell and Closed Cell Spray Foam Insulation
There are two main types of spray foam insulation, open cell and closed cell. Closed cell spray foam insulation provides a higher R-value, however it is more expensive than open cell.
Closed cell foam insulation is commonly used in insulating homes and should always be used over open cell foam in below grade applications as it is a natural vapor barrier. Closed cell foam insulation is also ideal for narrower width framing. Open cell spray foam insulation typically requires trimming after installation whereas closed cell spray foam insulation does not.
|Spray Foam Insulation Provides Maximum Energy Cost Savings and Structural Integrity
When installed properly spray foam insulation can yield up to a third more in energy cost savings compared to other types of home insulation. Also, since spray foam insulation adheres well to anything it is sprayed on to, and fills every nook and cranny that it is sprayed into, insect infiltration is also mitigated. In addition, spray foam insulation retains its R-value over time, unlike rolled or batt fiberglass insulation, and it is also an excellent sound insulator.
Also spray foam insulation, and in particular closed cell spray foam insulation, helps improve the structural integrity of walls, floors and ceilings. Consequently a home is less susceptible to sheering and racking caused by high winds.
Spray Foam Insulation is Expensive and Messy
Though spray foam insulation has many benefits it is more expensive to install than rolled or batt fiberglass insulation. It is also messy and if not installed correctly can cause walls to swell or buckle, and doors and windows to not function properly. Consequently when insulating an entire home or a large room forgo the thought of using diy spray foam insulation kits, and hire a professional who has the experience and equipment to install it correctly.
The small spray foam insulation cans are also great for insulating around electrical boxes, and plumbing and wiring holes in the wall studding. The gaps in home insulation around these particular areas are often major sources of air leaks.
