After 9 days total VOCs showed a rapid decrease and after that stayed at a very low level for a few months. The study concluded, "PVC floorings after 10 days of installation in the room should not be source of indoor air contamination."
In reality, the off-gassing should be the strongest during the first two weeks and continue to off-gas for up to months after it is placed into your home.
Due to the materials used in the production process of vinyl, it will sometimes emit various levels of VOCs into the air for a short amount of time after installation. These toxic chemicals can be harmful to air quality of the immediate environment it's installed in and may cause respiratory problems over time.
Vinyl Plank, Luxury Vinyl Plank (LVP), and Luxury Vinyl Tile (LVT) are very low in volatile organic chemicals (VOCs) and offgassing. Most people find it odorless, but those like me with a high sense of smell can pick up a little bit of offgassing.
Off-gassing can last between six months and five years depending on the household item and the chemicals used to treat it.
Vinyl is inexpensive, long-lasting flooring. But it often contains phthalates, chemicals that have raised safety concerns for young children.
Some phthalates are even known to be cancer-causing. Luxury vinyl flooring is known to emit these toxins. When it comes to smaller, less-ventilated areas of your home, the buildup of phthalates will be more severe due to the size of the space and the lack of ventilation.
Manufacturing vinyl flooring requires the use of toxic chemicals, and after installation, vinyl floors have been known to emit VOCs (volatile organic compounds). Off-gassed VOCs can adversely affect health and an indoor environment, particularly without windows or ventilation, will lead to higher concentrations.
Solid hardwood flooring is considered the safest and least toxic option as it's completely natural and free from any toxins. Solid hardwood floors are made of planks milled from a single piece of timber, which makes it a healthy flooring option.
If you have vinyl flooring, consider using an air purifier designed to remove VOCs like phthalates from your indoor air so you can breathe easier. Dust and vacuum frequently with a HEPA filter vacuum.
During the drying and curing process, the floor's finish releases potentially harmful chemicals into the air via evaporation, a process called off-gassing. Off-gassing is heavy during the first two days after application, and the floor's finish can continue to emit small amounts of VOCs for up to thirty days.
The Simple Way To Outgas Fast
Your three best allies in expediting the outgassing process are fresh air, ventilation and heat. Thus, sunning your items outside on a warm sunny day can greatly expedite the removal of VOCs without polluting the air inside your home.
Although levels of formaldehyde emissions from products like laminate flooring decrease over time, significant off-gassing may continue for months and even years. Significant off-gassing from laminate flooring can continue for months and even years.
When it comes to environmental impact, laminate has a slight edge over vinyl thanks to its recycled wood core. However, the melamine wear layer on the surface is still made of plastic, which may off-gas VOCs (volatile organic compounds) that can be harmful to people and pets.
LVT is made from polyvinyl chloride, or PVC. PVC is hazardous to both the environment and human health. There are many reasons for this. First, the production of PVC causes the release of toxins into the environment.
The vinyl sheeting itself does not contain asbestos, however, manufacturers sometimes incorporated a felt-like 'backing' for cushioning purposes. It is this backing which contains asbestos (typically 80–100 per cent).
The U.S. Department of Health and Human Services (DHHS) has classified vinyl chloride as known to be a human carcinogen (cause cancer). The U.S. Environmental Protection Agency (EPA) has classified vinyl chloride as a known human carcinogen by the inhalation route of exposure.
More specifically, vinyl plank/LVT is made of polyvinyl chloride—PVC. This plastic is used in tons of products, but it's not very eco-friendly. It can emit VOCs after installation, it can't be recycled, it's not biodegradable, and like all plastic, it is not sustainable.
The VOCs emanating from a product dissipate over time as the chemicals vaporize. VOCs from paint dissipate fairly quickly with most offgassing occuring during the first 6 months after application. Other sources, such as particle board may continue to offgas for 20 years or more.
Most gasoline odors will dissipate within a few hours with proper ventilation. However, it can take several days or longer to go away, especially for large spills. Open windows and use fans to help increase ventilation as much as possible until the odor subsides.
Most formaldehyde is released by 2 years [Park and Ikeda 2006].
