Frequently Asked Questions
Why is Spray Foam better than blown-in fiberglass or batt insulation?
When used alone fiberglass and other types of non-Spray Foam insulation (blown-in or batt) allow warm air to leak out of your house through the walls and ceiling.
Spray Foam insulation is sprayed onto the inside of the house's sheathing or roof decking and seals the surfaces it covers tight. This prevents warm air inside from leaking through the walls, ceiling or around lights in the ceiling. Spray Foam also acts as a vapor retarder and prevents warm, moist air inside your home from condensing in the walls, potentially causing moisture damage or even mold.
Can Spray Foam only be used in new construction?
NO, spray foam can be installed in the attic of a new or existing home or in the walls during a remodel.
Why haven't I heard of this before?
Spray foam has been used since the 1950's and has improved to follow all emmissions regulations and meets building codes. Home owners and contractors are steadily becoming aware of the tremendous benefits for the savings that spray foam provides.
How much does Spray Foam Insulation cost compared to other insulation methods?
Although the up front cost of Spray Foam Insulation is considered to be higher than most conventional insulation, it cannot be compared to conventional insulation. When using the Spray Foam Insulation system it actually air seals the building and eliminates energy loss, air leakage and the associated problems with moisture, mold, mildew, and condensation problems inside the walls. When calculating the actual cost, you need to consider the savings associated with the possibility of downsizing HVAC systems, as well as eliminating building wraps and a significant portion of the material and labor costs associated with an air-sealing approach.
What Is Spray Foam Insulation Made Of?
Spray Foam is an organic material developed from products of the petro-chemical industry. It is a two component system that is sprayed like paint. The chemical constituents are similar to those used in the manufacturer of many products already in your home, such as upholstery foam and the foam used for pillows and mattresses---although the properties of the foam are different. Spray Foam is an environmentally friendly urethane in which the ozone-robbing CFC's have been replaced with air and water.
How Long Does Spray Foam Last? Does It Change Physically?
Aging is not an issue with Spray Foam. It is inert, and its physical and insulating properties are constant.
Does Spray Foam Insulation Have Building Code Approvals?
Foam has approval of all four major building codes in the United States and the Canadian building code.
What is the difference between open-cell and closed-cell foams?
Both open-cell and closed-cell foams prohibit the movement of air and slow down the transfer of heat. Closed-cell foams, on the other hand, have low vapor permeance due to their cell structure. These foams, depending on thickness, may be considered a vapor retarder but not a vapor barrier. Closed-cell foams also have a high compressive strength which allows them to be used for exterior applications.
