Why should I get spray foam?
Answer: Spray foam insulation can form a continuous air barrier on walls, roofs, around corners, and on many surfaces in and around a home or building. It is created at the jobsite by mixing two liquids that react very quickly, expanding on contact to create rigid foam. It not only insulates, but seals gaps, and some foams can form a barrier against moisture and vapor.
By creating a tight barrier around a building, SPF helps prevent hot and cold air, moisture and vapor from infiltrating a building’s comfortable interior environment. SPF insulation is known to resist heat transfer extremely well, and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams and joints.
What is the cost of spray foam insulation services?
Answer: The first question many people ask is “how much will it cost to get my home insulated with spray foam?”. While the quick answer to this would be “more than fiberglass”, there is more to the answer that will justify the cost. Three or four times more might seem expensive at first, but you need to keep in mind that spray foam insulation provides a continuous barrier and is much more efficient than fiberglass, saving you money in the long run.
There are some prices below, however, think of these as a general idea of the cost. Price will vary according to size and scope of the project.
To get a closer determination of your cost, first figure out what you need. You will need to determine the type of foam and the thickness you will need for the project. There are two types of spray foam: Open Cell and Closed Cell.
Open cell foam is mostly used in roof lines, attics, exterior wall and for sound proofing.
Closed cell foam is mostly used for crawl spaces, basement and for commercial/industrial building. It is also used where a high R-value is needed with minimal thickness.
Next, you will need to determine your board footage.
The amount of Spray foam you will need is mostly calculated by the board foot, a 12 foot by 12 foot, 1 inch thick area.
Take the sq. footage of the area you want to spray and multiply it by the depth in inches of that area. A section which is 50’ in length and 10’ tall and framed on 2’x4’ wood studs would be 3-1/2” deep. With an above grade wood-framed wall, you will want to use open cell spray to the full thickness of the wall stud.
50 x 10 x 3.5 = 1,750 board feet
Travel, preparation time, and area of needed insulation will all play a factor in the price.
What are the benefits of Spray Foam Insulation?
Answer: Spray foam will form a continuous air barrier on walls, roofs, around corners, and on many surfaces in and around a home or building. It not only insulates, but seals gaps, and some foams can form a barrier against moisture and vapor. The foam is very versatile and can be added to new homes or very old homes to help save money on energy and keep your family warm in the winter, and cool in the summer.
Spram foam will preserve the long term value of your house by keeping out moisture and wind, lower maintenance costs, and reduce the need for repairs.
Can I still keep fiberglass insulation and use spray foam?
Answer: To install spray foam insulation, all old fiberglass insulation, wiring, and sheetrock needs to be removed and all debris cleared.
