The Way To Save Energy Costs

Insulating the attic of a house is a key ingredient of any energy cost-saving plan. It’s good for the environment, and for both the health of the home and its occupants.
 
A popular alternative to traditional building insulation, spray foam insulation is the new, best choice material. Developed by the U.S. military for insulating planes in the 1940s, it didn’t become a common home insulation choice until the 1970s. Since then it has undergone a rapid period of development, and there is a growing appreciation of its versatility and effectiveness.
 
There’s no question that spray foam insulation lowers utility bills. Up to 40% of a home’s energy is lost through air seeping out walls, windows and doorways. Spray insulation is typically 50% more effective than the older forms of insulation because it expands and fills construction defects. It’s considered a “green” product because of its ability to save energy in the heating and cooling of buildings.
 
Spray foam’s complete sealing protects against moisture, reducing the chance of mold and mildew growth, and the consequential health effects on humans. It is superior to traditional forms of insulation in reducing noise.
 
Spray Foam in Your Attic
 
Attics are typically the ground zero of insulation in a house. Attic insulation ensures that summer’s heat and winter’s cold never makes its way downstairs. A well-sealed attic can achieve remarkable reduction in heating and cooling costs. But what constitutes an optimal level of insulation?
 
A healthy attic should not allow the entry of heat – or moisture. Trapped heat and moisture can increase the chance of mold generation, as well as create an inviting environment for pests like termites. Experts say that the goal in insulation is to create the following condition: your attic’s internal temperature should be as close to, or equal, to the external temperature. Moisture levels follow the same rule. To achieve this, ventilation becomes a secondary part of your insulation strategy. Components include roof vents, turbine vents, soffit vents, electric pans, even solar powered attic vents.
 
Before your attic is brought to peak performance with spray foam, it may be necessary to remove pre-existing insulation. Presence of rodents, foul odor and leakage are the main reasons why people remove existing insulation. Some people may find themselves allergic to a particular type of insulation, especially if particles have become loose or airborne.
 
Spray Foam Installation
 
The installation of any kind of insulation in an attic requires a professional. Spray foam insulation, because it arrives in a non-solid form, needs trained professionals wearing protective gear. It is definitely not a job for the weekend home-renovator. The need for a professional adds significantly to the cost of spray foam. But, as pointed out, it immediately results in a substantial saving in energy costs.
 
There is no shortage of testimonials from home owners praising spray foam. They notice a reduction in how often their air conditioning is necessary in the summer, and a reassuring lack of dampness in areas covered with foam insulation. But the bottom line proof of spray foam’s value is the huge number of homeowners and businesses that are turning to this effective form of insulation.
