These can off-gas and produce a fishy or sickenly sweet odor if the foam does not harden or cure properly, and this off- gassing can continue for many weeks. The resultant odor has made some people ill. How long does fiberglass insulation smell last? Open the house windows and doors to let in as much fresh air as possible to get rid of a fiberglass smell indoors. It may take a couple days to dissipate, but allowing in fresh air will help it disappear more quickly.
The technician responsible for installing the insulation mixes the chemicals just before being sprayed into the home. If the technician or contractor improperly mixes the chemicals, including incorrect ratios of chemicals, the foam may give off an odor. You might also have tainted insulation.
Some blown-in insulation products contained compounds that smell like this. Any leaks in the duct system allows those smells to be distributed throughout the house.
Pets, smoke, mold and mildew, and cooking can create odors that permeate the air and linger around. These odors will eventually penetrate into the walls, carpeting, and furniture. Fiberglass pictured is the most common blown-in insulation, followed by cellulose. Mineral wool and real wool blown-in are less common but are healthier choices. The electrical components and wires in your walls and outlets are coated with heat resistant chemicals and plastic coating for insulation.
When these chemicals and plastic heat up significantly, they give off a burning odor that can smell like fish. Many fibreglass products give off fumes which can be harmful if inhaled in sufficiently large quantities. When machining finished items in cast resin or laminated fibreglass, the tiny particles of fibreglass or resin can be dangerous to the eyes and lungs. Mold often brings a not-so-pleasant odor that smells foul and musty. This step is a smart add-on to whatever ventilation strategy you choose.
There are various kinds of air filters out there, many of which offer better filtration than the standard 1" pleated type. For odor control, the best option is an activated carbon filter. We recommend the Carbon Clean It's a media filter designed for high quality filtration, maximum airflow, and odor removal.
The activated carbon coating is what distinguishes it from other media filters and absorbs strong smells so that they don't circulate throughout your home.
Or, for that matter, your nose and lungs. If you're really serious about indoor air quality and odor control, consider a Pure Air system , which combines contains a carbon filter and a HEPA filter. The solution generally involves some combination of isolating the stinky attic air, replacing attic air with indoor air, ventilating your living space, and aggressively filtering the air moving through your HVAC system.
In most cases, you'll stop smelling the spray foam, but you may have to try a few different tactics before you're successful.
Call Us Menu Schedule Now. Here's What to Do. Disclaimer: We're not a spray foam insulation contractor. Call the spray foam manufacturer. Here's why you might have to do this: Chemicals in the foam may not have mixed properly. Spray foam insulation is shipped as separate chemicals that must be mixed together prior to being sprayed. If the ratio for one or more of the chemicals is off due to contractor error or otherwise, the foam might not insulate properly.
It might also create a noxious odor. The space might not have been ventilated per manufacturer specifications. Before, during, and after applying spray foam insulation, it's really important to ventilate the spray foamed space so that the foam can off-gas properly.
If your contractor didn't adequately ventilate the space and some won't do it right! You'll need to do something about that, so let's explore your options. Seal your leaky ducts. The exhaust fan circulates the air from the house into the attic, not the opposite. While the spray foam will still smell, the odor will be directed out of the attic through the exhaust fan.
If the odor persists, it may be worth it to install a ventilation system to exchange the indoor air for filtered outdoor air. Another option that may help with odor from spray foam insulation is to seal the top plate and air gaps between the attic and living space.
However, sometimes this process can cause problems with the relative humidity in the attic space. In some cases, homeowners need to install a dehumidifier in the attic after pursuing this step.
An activated carbon filter may be the most appropriate for odor control. Avoid having to install a new ventilation system in your home by contacting Northwest Weatherization for insulation and weatherization services. We specialize in helping homeowners save money every month on their utility bills.
A bad installation of spray polyurethane foam stinks. Properly applied by a professional, spray foam should emit relatively low fumes that will altogether dissipate in about a week. Pretty much any time it gets wet it reeks of pee. Even without getting wet it will sometimes smell that way. Just it's natural scent. Since mold tends to grow on the surface of walls, under carpets, behind drywall and inside insulation , you'll smell it but not necessarily see it.
Most people say that mold smells like rotting wood or paper, whereas others say it smells like dirty, wet socks. Turn on exhaust fans to get rid of a fiberglass smell. Open the house windows and doors to let in as much fresh air as possible to get rid of a fiberglass smell indoors.
Set up fans in the windows to blow outwards. Roll down the windows of a car if that is where the fiberglass smell is a problem and air it out. The individual fibers in fiberglass insulation are made from water and recycled glass, so it won't absorb the water. Even when it gets wet , the fibers themselves remain structurally sound and functional.
If it starts to have a funny smell , it's a sign that the water that contaminated the insulation was dirty. Formaldehyde is a colorless chemical with a strong pickle- like odor that is commonly used in many manufacturing processes.
It easily becomes a gas at room temperature, which makes it part of a larger group of chemicals known as volatile organic compounds VOCs.
If the smell comes from everywhere in the house , rodents may be living in the air handler. Usually you can open up the air handler and look behind the air filter for signs of mice. You might also have tainted insulation. If it smells the same, that's your problem.
