FAQs
How much does spray foam insulation cost?
There's no flat price per house, and anybody who gives you one over the phone is guessing. What actually moves your number: square footage, whether the job calls for open-cell or closed-cell foam, how thick it needs to go, how hard the space is to get into, and whether old insulation has to come out first. We come measure it and hand you a written price. The inspection is free and there's no obligation.
Do you charge for an estimate?
No. We come out, look at the space, measure it, and give you a written price. Free, no obligation, and no pressure to sign anything that day. Call 423-710-2529 or request a quote through the site.
How does spray foam work?
A two-part mixture is applied by trained Foametix applicators to the inside surface of exterior walls, to the underside of the roof, and beneath floors in basements and crawl spaces. The spray mixture expands rapidly to fill all cracks and voids, completely and permanently adhering to wood, masonry, metal studs and joists.
What type of spray foam products are available?
There are two basic types: closed-cell, rigid spray foam and "soft" or semi-flexible open-cell spray foams. See the article Learning the Difference between 1/2-lb and 2-lb Spray Polyurethane Foam for more information.
Won't sealing my house lead to indoor air quality problems?
Most house design professionals will advise you to seal the house structure as tight as possible and provide the necessary ventilation through the heating and air conditioning system. Many systems employ an "air exchanger" which is designed to pre-condition (either warm or cool) the incoming outside air with the outgoing exhaust air. In this manner, you can build an extremely energy efficient exterior shell using spray polyurethane foam while still providing controlled and energy efficient ventilation.
At what point in the construction of my house should spray polyurethane insulation be applied?
Normally spray polyurethane insulation is installed at the same point in the construction cycle as other types of insulation. That is, it should be installed after the rough plumbing, electrical wiring, and heating and air conditioning ducts have been installed. If you decide to seal the entire exterior house shell with spray polyurethane, spray insulation may need to be applied in some areas before the ductwork is installed.
Can I use spray polyurethane to insulate an existing home?
Yes. A popular retro-fit use for spray foam insulation calls for foam to be sprayed directly to the underside of roofing system. This replaces the conventional blown in insulation used in the ceilings. Spray Foam can also be applied in the basement / crawl space to eliminate air infiltration from the ground. Our newest technology is Injection Foam; injection foam is used to fill existing walls by drilling small holes and injecting the foam from the outside of the structure.
What are the benefits of spray foam?
Save on utlities
- Foametix's Foam Insulation expands around every void and seals all air infiltration, the primary source of energy loss. Indoor temperatures stay constant, allowing decreased use of heat or air conditioning. This translates to savings on utility bills and extends the life of your heating and cooling equipment by four times.
Breath Clean Air
- Foametix's Spray Foam insulation eliminates air infiltration and seals a building so tight that an air to air exchanger must be installed. This results in premium indoor air quality (IAQ) because dust, fiber, pollen and other pollutants have no way in. Our foam application emits no VOC's or CFS's during application or throughout the life of the product.
Great Investment
- Investing in products to make homes more energy efficient pays significant dividends over a lifetime - with none of the wild fluctuations of Wall Street.
Open-cell or closed-cell: which one do I need?
Both are good foam; they just do different jobs. Closed-cell is denser, adds rigidity, and blocks moisture, which is what belongs under a metal roof or in a crawl space. Open-cell is lighter and more affordable, and it is an excellent air seal for attics and interior walls where moisture is not the enemy. We install both, and we spec it at the inspection based on what the space actually needs.
How long will my house be torn up?
Most of the work happens in spaces you do not live in: the attic, the crawl space, an unfinished wall cavity. Time on site depends on square footage, how much prep the space needs, and whether we are pulling old insulation out first. You will get the schedule in writing with your quote, before anything starts.
When can we go back in the house?
Same day, once the area has been ventilated. Our crew ventilates the space before they leave. If anyone in the house has asthma or chemical sensitivities, tell us up front and we will plan the timing around it.
Is the foam guaranteed?
The material carries a manufacturer lifetime warranty. Spray foam also does not sag or settle the way batts and blown-in insulation do, so once it is in and cured it stays where we put it.
Will it actually lower my power bill?
Air leakage is the single biggest reason Chattanooga HVAC systems run nonstop in July, and sealing the building envelope is what spray foam does better than any other insulation. How much you save depends on how leaky the building is right now. A 1970s house over a vented crawl space has far more to gain than a tight new build. We will tell you honestly at the inspection whether the payback is there.
When can spray foam be installed?
Foametix Spray foam insulation is professionally installed at the same point in the construction cycle as other types of insulation. That is, it should be installed after the rough plumbing, electrical wiring, and heating and air conditioning ducts have been installed, but before the interior walls are completed in new home construction. In some cases spray foam also can be applied in older homes, to the inside of roofs and under floors after construction has been completed.
Do you insulate metal buildings and pole barns?
Yes, and it is a large part of what we do. Metal panels sweat: warm humid air hits cold steel, condenses, and it rains inside your own building. Closed-cell foam sprayed to the underside of the panel puts insulation in direct contact with the steel, so there is no gap left for moisture to condense in. More on metal building insulation
Do you remove old insulation?
Yes. Wet, matted, or rodent-damaged insulation has to come out before new foam goes in, and we handle the removal and disposal as part of the job. More on insulation removal
Do you serve my town?
We are based in Chattanooga and run crews up to 100 miles out, across Southeast Tennessee and North Georgia. That includes Cleveland, Hixson, Signal Mountain, Ooltewah, Dayton and Athens, and down into Ringgold, Fort Oglethorpe, Dalton, Trenton and Calhoun. If you do not see your town, call 423-710-2529 and we will tell you straight whether we can get a crew there. Full list on our service areas page
