Is there a safe foam insulation?
Foam insulation has been used safely since its invention in the 1940s. Initially used as a fire retardant material, it has since evolved into a versatile building product. The most common type of foam insulation is polyurethane (PU) foam. PU foams have been around for decades and are considered safe by the EPA.
Natural Latex Foam
Latex foam can be either synthetic and natural. Synthetic latex is often made with toxic chemicals that are not safe for human contact. Natural latex foams, such as Dunlop or Talalay latex, are safer alternatives.
Icynene® is a non-toxic spray foam. It doesn't contain formaldehyde, HCFC, CFC or HFA so it produces no toxic emissions. And, unlike polyurethane foams, Icynene® foam cells are only filled with air.
After proper curing, spray foam insulation is safe and should not cause any health-related or even structural problems in your property. However, it is highly important for you to call a licensed insulation contractor to install this type of insulation in your property.

According to the EPA, occupants must stay away from the building while it cures (and as long as the dust remains) for at least 24 to 72 hours, something they, devastatingly, are not always told. If the spray foam continues to off-gas, the building can be inhospitable to occupants for years.
No it's not, 24 hours after spray foam has been applied there will be no toxic chemicals present, as the gas is made inert. This makes it perfectly safe for humans or animals to be present in the sprayed area.
When should you not use spray foam insulation?
DON'T use expanding foam around outlets and recessed can lights. In the quest for a draft-free home, it's natural to want to add some insulation around electrical outlets, but expanding foam might not be the best type of insulation there.
Spray foam has an off-gassing period of a few hours until it's 100% cured.
Properly applied by a professional, spray foam insulation should emit relatively low fumes that will altogether dissipate in about a week.
Insulating the attic rafters with spray foam creates a conditioned space where your attic is the same temperature as the rest of your home. This keeps the external weather and moisture outside of the attic space so you don't have to worry about any moisture problems or air infiltration.
Yes, expanding foam can be used as insulation. Expanding foam can be defined as a two-component mixture composed of two materials that react when mixed. This causes the foam to expand and harden, providing an insulating material.
Cellulose insulation is another environmentally friendly option as it's made from about 80 percent recycled paper materials. The costs of these insulation materials will also be more wallet-friendly than spray foam.

Available in spray-on form which uses water as its main blowing agent, soy foam expands inside the wall like other types of spray-on insulation, but has no toxic gas emissions. Soy foam insulation is also available in rigid form, which is much less dense than other kinds of rigid foam.
Styrene. Styrene is a plastic-based material that works great for signage with a life expectancy of less than a year. It's 100% waterproof and doesn't tear, dent or crack the way foam core can. Not only that, but thinner styrene sheets can be rolled and placed in a tube for easier shipping.
Corrispring cardboard inserts are a cost effective, recyclable and innovative polystyrene and foam alternative.
Is polyurethane foam safe?
Polyurethane is the result of the chemical reaction between a polyol and a diisocyanate. Once the chemical reaction of its components has taken place, the result is a polyurethane foam that is completely inert and harmless to humans.
At Greer, we love using Walltite CM01 for our customer's insulation projects. What we love is that the benefits of this foam go way beyond a safe, long-lasting insulation product. It's an eco-friendly spray foam insulation with one of the lowest environmental footprints without sacrificing quality and performance.
Latex is a natural repellant to dust mites & other allergens, and is also resistant to mold and mildew. It is used as a healthy, eco-friendly replacement for polyurethane foam in cushions & padding for upholstery.
Although UFFI is still used today, most modern spray foam insulation products do not contain formaldehyde. However, they are still far from green building materials.
Even if you do not become sensitized to isocyanates, they may still irritate your skin and lungs, and many years of exposure may lead to permanent lung damage and respiratory problems.
Pink fiberglass insulation effectively keeps homes warm in the winter and cool during the summer. But it does not come without a price. The material could trigger asthma, bronchitis, and eye irritation. Moreover, it could cause itchiness and skin irritation.
Because any type of spray foam is combustible, along with most other building materials, we need to protect the wall from the foam. By installing gypsum board over the foam, we have protection on the inside of the building for a life-saving purpose.
Recent media and industry reports suggest some homeowners have found it difficult to remortgage or sell properties that have spray foam insultation. If installed incorrectly, spray foam insulation may lead to condensation which can affect a roof structure.
But in many spray foamed attics, it can be hard to manage humidity. During the spring, summer, and fall, relative humidity (RH) in a spray-foamed attic often exceeds the comfort threshold of 60%. When it exceeds that threshold by too much – and for too long – you could experience problems, like mold growth.
Vapor barriers are often installed in basements and crawl spaces to prevent ground moisture from leaking in. In houses with spray foam insulation, however, vapor barriers are not necessary.
Do you need fresh air with spray foam insulation?
Therefore providing mechanical fresh air ventilation is especially important in spray foam houses. Mechanical ventilation systems allow a constant flow of outside air into the home and can also provide filtration, dehumidification, and conditioning of the incoming outside air.
Spray foam can provide the thermal, air, and vapor control layers in both new and retrofit construction. Unvented roof strategies with open cell and closed cell SPF insulation sprayed to the underside of roof sheathing have been used since the mid-1990s to provide durable and efficient building enclosures.
Air will circulate from the living space up to the attic, hit the spray foam barrier, and then move back down. Adding spray foam to the attic flat will seal it off from the rest of your house. The air barrier created with spray foam insulation blocks the air you pay to heat and cool from moving up into the attic.

- Irritation of the eyes and lungs.
- Fever.
- Stuffy nose.
- Sore throat.
- Tightness in the chest.
The good news is that off-gassing odors usually go away within a few hours to a few days. If the smell bothers you, you might want to consider opening your new mattress in a separate, well-ventilated room, removing the cover, and allowing it to off-gas before you bring it into your bedroom.
As a product, spray foam insulation does not attract mold. And unlike wood or metal, spray foam does not rot, rust or deteriorate. This means that an area properly sprayed with foam insulation will never become a food source or a hospitable environment for a mold colony.
Spray foam insulation does not off gas, or emit any harmful chemicals. Third party laboratories have carried out vigorous testing during and after the installation of spray foam insulation and found negligible levels of exposure just 24-hours after spraying.
Burning foam will emit mainly carbon monoxide, carbon dioxide and small traces of other toxic gases, such as HCL, HF and HCN. As with burning of any organic material, avoid breathing the fumes.
Fiberglass batt is considered to be the best insulation for attics. Compared to other insulation materials, it is the cheapest and easiest to install. Fiberglass batt is also incredibly energy efficient, as it helps to slow the spread of hot and cold air.
In most cases, we recommend the open cell spray foam on the attic flat and roof deck, but there are instances where the closed cell is the better option. RetroFoam of Michigan has been insulating attics since the beginning of time, or at least since we started this business close to 15 years ago.
Is it better to insulate attic ceiling or floor?
So insulating the floor of the attic is not only the best solution, but it is also the simplest and cheapest. In practical terms you can choose between mineral wool or insulation boards.

Larger gaps should not be caulked. Most builders seal the gaps between a window frame and the rough opening with canned, one-component spray foam. Low-expansion foam is usually best, because other types of foam can exert enough pressure to bow window jambs inward and cause a window to bind.
Use the foam for insulation or soundproofing.
Whether you're trying to insulate your garage, a small workshop, or just want to add a little soundproofing to a kid's playroom or garage band area, the foam from your memory foam mattress can help.
Latex is a natural repellant to dust mites & other allergens, and is also resistant to mold and mildew. It is used as a healthy, eco-friendly replacement for polyurethane foam in cushions & padding for upholstery.
Just like almost every other substance on the planet, polyurethane foam off-gasses, or releases compounds into the air. Yes, you breathe in these compounds when you sleep on these mattresses. But no, they're not going to hurt you.
Product description. Clevr Extra Large Interlocking EVA Foam Baby Play Mat is made from high quality, durable and non-toxic EVA foam. These versatile mats transform any area to a fun interactive playroom for your child's development and entertainment.
Toxicity of PUR foam is a myth - you do not have to be afraid of negative effects of the components from which it is made. Polyurethane foam is entirely harmless to health once it has dried. Tests carried out by PU Europe have not indicated the presence of harmful and toxic substances.
What are the harmful effects? Exposure to chemicals commonly found in most polyurethane foam products may cause serious or fatal respiratory disease. These chemicals are powerful irritants to the mucous membranes of the eyes, gastrointestinal tract, and respiratory system.
- Fiberglass batts;
- Rock wool batts;.
- Blown-in fiberglass or cellulose, manufactured from recycled paper and similar products.
- Recycled cotton (denim), normally used for soundproofing but also provides R-13 thermal insulation.
Is there formaldehyde in foam?
Some memory foam mattresses contain toxic chemicals such as formaldehyde, benzene, and naphthalene. Memory foam may contain isocyanates, which, according to the Occupational Safety and Health Administration, can cause irritation of the eyes, nose, throat, and skin.
Although UFFI is still used today, most modern spray foam insulation products do not contain formaldehyde. However, they are still far from green building materials.
Polyurethane foam is used in most mattresses on the market. But polyurethane is made from petroleum chemicals that can emit VOCs—harmful chemicals that can cause respiratory irritation or other health problems.
As a closed cell foam, EVA material is firmer than open cell foams and allows for subtle movements when standing on it without much risk rolling ankles. This quality also makes it great as an anti-fatigue flooring material.
The use of EVA and PE foam is very similar due to their properties, but EVA foam is much more well-liked to be applied in the package that needs a die-cutting process. This method of use is chosen because it is cheaper for EVA, however, PE foam can also be cost-effective choice for customers with special needs.
The EU has since harmonized safety standards around allowable formamide release from EVA foam mats and related products. Other countries, however, haven't followed suit in creating formamide limits in EVA foam tiles or baby mats.
