The Green Home Guide is a site that advocates for sustainable building practices and the use ofenvironmentally safe building materials. Therefore, endorsing the use of laminate flooring would not bein keeping with our mission.
With regards to leaving the material in the garage to "off gas", I would not recommend this strategy asthose chemicals will off gas into spaces that you and your family use every day.
- Unless you have a carportso that the gasses can actually escape.
- However, exposing the materials to temperature swings andmoisture would not be wise either given the climate zone you are in.
Previous experiences with real wood
As for your past experience with wood flooring in your basement, there may have been someinstallation steps 'skipped' with your previous floor that led to its failure such as:
- the slab may not have been sealed,
- a moisture barrier may not have been installed,
- down spouts from the roof were clogged and causedwater to pool at the foundation and into the basement.
The list of culprits can be extensive.I wouldencourage you to consider other flooring options such as those mentioned in the green basement flooring archive.
Air cleaning plants
Regarding plants, there are indeed several plant species that have been clinically proven to help "clean" indoor air.
I amnot personally familiar with which volatile organic compounds each species absorbs best but you can read the Q&A "Can I use house plants to improve my home's indoor air quality?" and Wikipedia's air filtering plants listto help you find the right plants for you and your home.
Note: consider door threshold heights when selecting any flooring material (and underlayment) toensure that all doors can be opened properly and maintain a good air seal.
