Each type of insulation has its inherent pros and cons. We will walk you through the benefits of each insulation type, and recommend the application that is best suited for your job and budget.
R-Value is the industry standard for measuring the insulating power of any material; The higher the R-value, the greater the insulating power.
Insulation is not just for attics and outside walls. Insulation should also be installed in other areas including ceilings with unheated spaces, basement walls, floors above vented crawl spaces, cathedral ceilings, floors over unheated garages or porches, knee walls, inbetween interior walls (especially bathrooms), and ceilings or floors for extra sound control.
Closed-Cell spray Polyurethane foam is highly dense and when sprayed expands up to 30 times its original liquid volume producing an R-value per inch of 6.8. In Closed-Cell spray foam, cells or bubbles in the foam are compacted together, are not broken and each is filled with an inert gas selected to make the insulation value of the foam as high as possible. An example of Closed-Cell foam insulation that we benefit from every day would be the insulation found in your refrigerator and freezer. The advantages of Closed-Cell foam include its strength, higher R-value, and greater resistance to the leakage of air or water vapor making it ideal for windy, damp and water prone locations, such as coastal areas, below grade, crawlspaces, or for the whole house. For many of our clients, Closed-Cell foam is the product of choice. While more expensive than Open-Cell foam because of its density, at 1 inch thickness Closed-Cell foam develops an air barrier and at 2 inches a moisture barrier. Closed-Cell Spray Foam is the only FEMA approved flood resistant insulation material.
Open-Cell spray Polyurethane foam is soft – like a foam cushion in a pillow and is an excellent air and sound insulator. Unlike Closed-Cell foam, Open-Cell foam is less dense, with each Cell in the foam being broken, thus allowing air to fill all of the spaces in the material. Upon spraying Open-Cell foam expands up to 150 times its original liquid volume, thereby filling all nooks and crannies in the wall cavity. When spraying is complete, the excess foam is shaved off the studs, leaving a flat surface over which dry wall or other material can be applied. With an R-value of 3.9 per inch Open-Cell foam gives you an air barrier at 5 inches of thickness. Uses for Open-Cell include spraying directly to all walls of a house, and as sound proofing for media rooms. Open-Cell foam may also be direct sprayed to the underside of roof decks to create a highly efficent seal attic system.
Insulation saves money, increases home comfort, and protects the environment by reducing energy use. According to the U.S. Department of Energy (DOE), the typical U.S. family spends close to $1,500 each year on energy bills. DOE statistics show that, typically, 44% of a homeowner’s utility bill goes for heating and cooling costs. DOE states that homeowners may be able to reduce their energy bills from 10% to 50% by taking certain steps. One of the major steps is increasing the amount of thermal insulation in their existing homes or purchasing additional insulation when buying new homes.
Unless your home was constructed with special attention to energy efficiency, adding insulation will probably reduce your utility bills. The amount of energy you conserve will depend on several factors: your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use. Energy conserved is money saved, and the annual savings increase when utility rates go up. Insulation upgrades also add to the value of your home.
Yes. Insulation is an efficient way to reduce unwanted sound, and it is commonly used to provide a more comfortable and quieter interior environment. Insulation effectively reduces noise transmission through floors and through interior and exterior walls.
