Abstract
Described herein are methods for installing field-assembled flooring systems wherein the underlayment is a hybrid design that includes a combination of structural board and cementitious product. The hybrid design is configured to reduce or eliminate the curing time requirement after pouring the cementitious product (e.g., gypsum concrete). The field-assembled flooring systems can reduce or eliminate the chances of the onset of mold due to high moisture levels by removing the cementitious product from the prone areas and replacing it with structural boards. The structural boards (e.g., cellulose fiberboards) can be installed in non-critical areas such as underneath cabinets, around the perimeter of the floor, under bathtubs, in non-walk-in closets, anywhere drywall reaches the floor, or the like.
Claims22
A flooring system having a hybrid underlayment, the flooring system comprising:
- a plurality of isolation boards adhered to a subfloor in a targeted area, the targeted area lying within a first portion of the subfloor adjacent to a wall;
- a cementitious product poured in a second portion of the subfloor so that the poured cementitious product is level with a top side of the plurality of isolation boards, the plurality of isolation boards defining a pour stop for the cementitious product;
- and
- a sealant applied on top of the poured cementitious product such that the sealant covers intersection locations between the poured cementitious product and the plurality of isolation boards;
- wherein the plurality of isolation boards is comprised of water-resistant isolation boards, fire-rated cellulose fiberboards or combinations thereof.
A method for installing a hybrid underlayment of a flooring system, the method comprising:
- adhering a plurality of isolation boards to a subfloor in a targeted area, the targeted area lying within a first portion of the subfloor adjacent to a wall;
- pouring cementitious product in a second portion of the subfloor so that the poured cementitious product is level with a top side of the isolation boards, the isolation boards defining a pour stop for the cementitious product;
- and
- applying a sealant on top of the poured cementitious product such that the sealant covers intersection locations between the poured cementitious product and the isolation boards;
- wherein the plurality of isolation boards is comprised of water-resistant isolation boards, fire-rated cellulose fiberboards or combinations thereof.
