More than any question this is what most people ask.
Below you will find information regarding the Following questions.
There are too many variables to give a Square footage price or general cost unless you know exactly what Poundage of foam you are pricing out.
However The Short answer: Spray foam Materials are more costly and much more effective that traditional insulation materials. On average Spray foam runs About 30% more at the very minimum of the cost of fiberglass and cellulose insulation Depending on the Weight of foam chosen. But, spray polyurethane foam is so effective it can not be compared to standard insulation materials such as provide a continuous Air barrier, Proven Energy Saver, The most powerful Insulator on the market, Moisture Barrier,Deters Mold Growth, indefinite lifespan, Does not shrink, Crack, Settle and is Eco Friendly. Keep in mind that the prices below are budgetary, and will vary job-to-job.
Spray foam is sold by the board foot not square foot. ( 12 x 12 x 1 inch thick) Spray foam has so many weight options of Open cell and closed cell foam, Such as Envirofoam™ Low Density Foam, Medium Density Foam, High Density Foam, TRU-2 and greater weights. Learn about foam weight here
With all the different materials available we would need to know the exact foam poundage, depth, R-value desired and application.
The best way to get a price is to supply the plans or have a site visit and discuss with the installer what you are wanting or an idea of a budget so you can get the best possible application for the specific budget you have in mind.
If you are going to compare bids you will want to compare the exact material and depth of material and application areas. Walls, box sills, roof deck or attic ceiling. If not, you will receive bids that could be hundreds or even thousands of dollars apart. Making sure you are getting bids for the exact same material is key.
Nationally open-cell Spray foam Averages $0.29 to $0.65 per board foot and closed-cell Spray foams average $.90 to $1.50 per board foot for material cost only not including Labor, Prep ETC. These are National Averages and are not Envirofoam's Pricing. Envirofoam Pricing is Lower than the national Averages because we not only Install the foam We are also the Manufacture of the material.
The Biggest reason for the Large Price Differences between installers is the weight of the foam they are using. Most Consumers do not know there are Dozens of different types of Spray foam Materials and weights. Most consumers think there is just Open cell and closed cell foam. This could not be further from the truth.
The weight of the foam dictates the density of the material.
Example: An open cell foam AKA 1/2 Pound foam weighs 1/2 LB per cubic foot and you can get approx 16,000 Board feet per set with an R-value of 3.85 per inch.
A set of 2 Lb 245 FA blown Closed cell foam would weigh 2 Pounds per cubic foot of material but only get approx 3,000 board feet per set at an R-value of 7 per inch.
Because there are so many different weights of foam you may have one company biding your project in a 2LB 245 fa blown material and another company bidding the same project in a 1.5Lb foam. Both companies are calling their foam " Closed Cell Foam" however the weight and R-Value of the material are not the same. The final cost difference between the bids could be thousands of dollars difference making you think that one company over the other is giving you a great deal. In reality you may be getting taken advantage of and you would never know .
Not all of these questions May pertain to your install. Some are for new construction homes and some are for pole barns and Garages. Below are links you can Print out to ask your installer.
1. What Material Manufacture are you using?
2. What Poundage of foam are you using in the attic?
3. What depth of material are you spraying in the attic?
4. Are you spraying the roof deck and doing an envelope install Or the flat drywall ceiling?
5. What R-Value will I have when completed in the attic. Actually, Verifiable R-value not a comparative or functional R-value but a Verifiable R-Value the inspector can verify.
6. What Poundage of foam are you using in the walls?
7. Are you OK with us sending off samples of the foam for a density Check?
8. What depth of material are you spraying in the walls?
9. Do you Prep the Doors, windows, and floors and do you guarantee no over-spray to these areas?
10. Does this include fire stopping per code?
11. Does this include installing low rise foam to windows and doors?
12. Does your Quote include the garage and Box Sills ( sill Plates ) ?
13. Do you have Work comp insurance and General Liability Insurance and can I get a Binder?
