Ferma Wood Floors
FERMA Solid and Engineered Products can be installed on and above grade. Solid Products may be nailed down with cleats or staples over wooden sub-floor, using specially designed hardwood floor nailer. Engineered Products may either be glued down over plywood or concrete sub-floor, or simply nailed down with cleats or staples over plywood floor, using specially designed hardwood floor nailer.
FERMA does not recommend installation of its products over radiant-heated sub-floor.
INSTALLER AND OWNER RESPONSIBILITY
Hardwood floors increase the value of your home and enhance its beauty. Hardwood is a natural material that may reveal imperfections. FERMA pre-finished hardwood floors are manufactured to meet the highest quality standards of the industry, which permit a defect tolerance and grading variance not to exceed 5%. The defects may be of manufacturing or natural type.
FERMA ensures that the its products are free of manufacturing defects and following strict guidelines, each wood strip is individually and meticulously inspected to select the right pieces belonging to the grade being produced. Prior to installation, installer must make sure that every sub- floor inspection and pre-installation requirement listed in this guide is satisfactorily met or even exceeds minimal specifications.

Final grade, manufacturing, finish quality check and approval of product before installation remains the sole and joint responsibility of owner and installer, even if owner is absent at time of installation. Installer must exercise sound judgment [common sense] before and during installation; strips showing any glaring defects or imperfections must be trimmed and used in hidden places or not used at all. Once nailed down in place, any strip is considered as having been accepted by installer and owner.
When ordering hardwood flooring, it is recommended to add 8% to 10% to the square footage needed as allowance for cutting waste and color grade variation, according to type and place of installation.
When in doubt, installer should not install any strip showing visible grade, manufacturing or glaring defects, if unable to use in hidden places or trim imperfection. If any installed strip must be replaced at a later date, FERMA's liability shall be solely limited to the replacement of defective products [materials only] in excess of the 5% industry accepted norm, excluding trimming waste allowance. FERMA shall not in any case be liable for installer's lack of judgment, quality of installation, labor and installation costs.
