However, currently the major flooring brand launched the "no added formaldehyde" insects resistant composite decking and railing manufacturers parquet floor focused on the field, and each different process, and some of the floor with the biological glue developed new structures and installation techniques.
Since the production process is more complex and requires additional production equipment, "added formaldehyde-free" floor price higher definition of composite staircase than ordinary floor about 30%. Indeed superior environmental performance these biological glue floor is really greener it? Just out on the market new soy protein glue floor have been tested, and its environmental performance is indeed very good, the measured indicators l shaped outdoor wooden bench to achieve the E0 class level.

However, due to the wood itself contains formaldehyde, formaldehyde-free floor to say a bit too much, there is no problem to use.
