Sub-floor Sub-floors must be inspected and tested to make sure that they are within acceptable tolerance parameters. Both the flatness and levels of the sub-floor must be within tolerance. Noise Control There are various building regulations governing the transmission of sound and impact noise in new build and refurbished buildings and many ways of dealing with walls, ceilings and floors to minimize the problem. Installation There are three types of floor installation, a sub-standard installation, an average installation and an excellent installation, as ensured by Mafi USA’s in-house installers. As a rule of thumb, they are priced accordingly. Under Floor Heating As any informed engineer, architect or contractor will tell you, wide plank wood floors that are to be installed above underfloor (radiant) heating must be exceptionally well engineered. Solid non-engineered wood will exhibit deficiencies such as large gaps between the planks, cupping and warping. Floor Finish and Care Your choice of wood floor finish will affect both its appearance and method of maintenance. The many differing finishes available can be quite confusing. Potential contenders include, varnish, lacquer, wax, floor cream, paint and oil. FSC Mafi USA proudly boasts its Forestry Stewardship Council (FSC) pure 100% certification. This means that for marked products, we can guarantee that all processes are FSC conform, from felling the tree up to delivery of the floor.
