What is R-value?
R-value measures the insulation's resistance to heat flow. The higher the R-value, the better the insulation will perform.
What are the advantages of Spray Foam?
The main advantage of spray foam insulation is that it does not only insulate, but it creates an air-tight seal. This prevents temperature fluctuations in your home and creates a more healthy and comfortable living environment by minimizing indoor allergens, such as: pollen, dust, mold, mildew, and other pollutants. Last but not least, it will never loose its R-value overtime, compared to traditional insulation.
How much can I save with air sealing and insulation?
Every home is different. There are a lot of factors that play a role into how much can be saved, so there is no good answer for this. Usually savings can be anywhere from 20-50%, but regardless of how much can be saved, anyone will appreciate better indoor air quality and how much more comfortable their home is.
What is stack effect?
There is always a pressure difference between the air outside and the inside your home. As the warm air in your home rises and escapes at the top, either through unwanted holes in your ceiling (lights and ceiling fans), vents, or open windows; the cold air from the outside enters through unwanted leaks, windows, and doors to replace it. The stack effect is greater during the winter due to the higher temperature differences. During the summer the stack effect is reversed.
What's wrong with fiberglass or cellulose insulation?
Absolutely nothing. As long as it has been properly installed and all air leaks have been sealed, this insulation can perform well. These products will not work as they are designed to when air moves through them.
Is a good insulation job more expensive?
Just like any-other thing, you get what you pay for, and the same applies to home performance. However, a good insulation job will always pay for itself.
Why is air sealing important?
By air sealing your home you will have more control of the air enters and exists your home. The more conditioned air exists your building envelope, the more the HVAC system will have to replace. Once you have sealed all air leaks your heating and cooling system will work more efficiently, you will have a more comfortable home, and lower energy bills.
Isn't an air-tight house bad?
Sealing a house tight is not bad, as long as it is ventilated right.
Why can't my upstairs stay cool and comfortable?
Blame Physics. Hot air rises and cold air sinks. During the summer, the air you condition will drop and escape your home. Without a good thermal and air barrier, your home will absorb the hot heat form the outside, specially the heat in your attic and roof, and your HVAC system cannot keep up.
