Not all insulation is make equal , especially for those who live on in particularly hot or frigid clime . Two of the most popular options are spray froth and fiberglass . However , there ’s a handsome cost disparity between the two . For those debating spray foam insularism cost vs. fibreglass , the following can help oneself narrow down the choice base on effectiveness , sustainability , budget , and overall value . Once a conclusion has been made , thebest insulation contractorscan serve instal the proper option .
Spray Foam Insulation vs. Fiberglass Insulation
Spray - in foam insulation is an insulant material that is made of a polyurethane liquid that expands to fill up the interior of stud walls , rafters , and joint spaces . Since it fills a space , spray foam roof insulation installation is common . It has a high R - value ( which is the step of how well a material insulates ; the higher the roentgen - time value , the unspoiled ) , but foam detachment prices make it the most expensive to install . Just how much is spray froth insulant ? It set out between $ 0.44 and $ 1.50 per board invertebrate foot ( 1 foot by 1 foot by 1 inch ) . It also comes in open - cellular phone and unsympathetic - cell variations , with open - cell flesh out to fit smaller recession and fissure and closed - cellphone a laborious , more effective material that also is moisture - resistive . Spray foam attic insulation costs will be lower than insularity install behind finished rampart .
Fiberglass insulation is much more affordable than spray froth insularism and easier to set up , but it is more permeable than spray foam . Like its name advise , fiberglass insulation consists of fine glass fibers and comes in a variety of forms , from blanket and unaffixed - filling to rigid boards . Batt and unbending insulant R - values will be higher than that of blown - in insulation because the material is denser .
How to Estimate Insulation Costs
compute thecost of insulationis comparatively easy , so long as you have a full measuring tape recording and a calculating machine . It ’s fresh to first measure the breadth and height of the bulwark and multiply the two number together to get the area . Then , multiply the arena of the bulwark by the depth of the stud space .
For example , if the wall has 2×4 stud , the stud space will be 3.5 inches thick-skulled . Multiply this number by the area , which will determine the number of board foot that will be filled with either spray foam or fiberglass insulating material . Thecost of spray foam insulationfor occupy a 3.5 - column inch - chummy wall ranges from $ 123 to $ 182 if using open - cell and will increase for shut - mobile phone . Even inexpensive foam insulation add-in will cost more than fiberglass batt insulation .
Spray Foam Insulation Costs vs. Fiberglass Insulation Costs
One of the major contributing factor to homeowners deliberate spray foam or fiberglass insulation is the cost . broadly speaking , spray froth is more expensive than fiberglass , and open - mobile phone nebuliser foam is less dear than unsympathetic cellular phone .
Insulation Costs by Area
The region of the plate being insulated can sham the toll a customer pay for an insulation task . The costs to insulate select areas of the home are as follows :
1. Spray foam insulation is the most expensive type of insulation and has a high R-value.
well for add insulation to finished area , spray foam insulation projects cost an average of around $ 2,500 , which make this eccentric of insulation the most expensive type . Part of the reason this eccentric of insulant costs more is due to its high R - value , which is an indicator of how well the insulation observe heat energy from leaving or enter the plate . For example , closed - cell froth insulation has an R - economic value of up to 7 per inch of thickness , compared to cheaper fiberglass insularity that has an R - economic value of up to 3.8 per inch of thickness . ( For comparison , 2 - in froth detachment board has an R - value of about 7.7 , and bollocks up - in cellulose insularism has an R - note value of 3.8 . ) The in high spirits the R - note value , the more likely it is to carry through on warming and cooling visor .
2. Spray foam insulation has the highest ROI of all insulation materials.
While homeowners will pay more up front to install spray froth insulation , it will pay off off in the long run due to reduced energy cost . count on the sizing of the outer space , geographic fix , and the habitation ’s vigor usage , homeowner could see a income tax return on investiture in as little as 3 to 5 years .
This is especially true for foam insulation panels installed in the attic , where vigour run to get lost more easily in cold climates . Although the average cost of spray foam detachment may be mellow than for any other type of insulant , it can result in 10 to 15 percentage savings in novel , already insulate rest home and up to 30 pct savings in older , ill insulate home .
3. Fiberglass batts are the most economical form of insulation.
There ’s a reasonableness fiberglass batts are used in about 85 percent of abode , and the main reason is the insularity ’s low price . It ’s the most unwashed contour of insulation used on the market , peculiarly since the material is easier for expert DIYers to treat themselves .

For model , installing fiberglass insulating material in a 500 - straight - foot section of the home can be anywhere from $ 150 to $ 750 . Plus , this case of insulation is easier for have DIYers to install , so those who are comfortable taking on the project themselves could lay aside on labor costs .
5. Both spray foam and fiberglass insulation can last for over 80 years, but fiberglass is susceptible to moisture.
As long as it ’s not exposed to moisture , fiberglass insulation can last anywhere from 80 to 100 old age . The same is true for spray froth insulation ; however closed in - cell spray foam is watertight . When fibreglass come in in contact with moisture , either from uttermost conditions or a busted pipe , the fibre tend to clump and miss their effectiveness . If the fiber get too wet , they may even need to be replaced whole . For those who live in an area with high-pitched humidity or the potential drop for intemperate rainfall or dangerous storms , spray froth detachment may be worth the higher cost .
