Hardwood Formalhyde free

Can be great but need to study if a given manufacturer makes stable boards. Controversial product.
Cabinet panels made from recycled straw — an ecological source but, must study the adhesives used.

Lots of products fall into the category of Panels, and most use a lot of glue to turn material into a panel.
The first step is to avoid the most common panel adhesive, which is formaldehyde. Panels, like plywood or particle board, that do not use formaldehyde usually say “formaldehyde free” on the packaging.
Many panels are publicized as “mould resistant”. Using chemicals to make them mould resistant is usually not a good idea for people who experience Multiple Chemical Sensitivities. Using surfaces, such as fibreglass-covered drywall, works for many people once the fibreglass has off-gassed.
Cement boards are generally quite inert and volatile organic compound (VOC) free.
Note: “TAPES” in the listing, as panels often need to be joined together, like with drywall tape, or interior or exterior gap sealing tapes.
