This disclosure is related to use of a floor tile for use in new construction or renovation. In particular, this disclosure is related to a tile with beneficial properties in applications wherein a substrate can be unstable and/or noise dampening or thermal insulation is desirable. Additionally, the disclosure is related to a tile for use when a temporary flooring material might be desired or a floor with the ability renew and replace easily with no messy or common construction processes would be associated with the replacement process. Additionally, the disclosure is related to a tile for use with a simple installation in which almost no prior experience would be required to complete a satisfactory installation in a floor application.
The statements in this section merely provide background information related to the present disclosure. Accordingly, such statements are not intended to constitute an admission of prior art.
Tile is widely used as a decorative and functional material for use in residential and commercial buildings. Tile provides a finished look, and it also is easier to clean in some applications than other types of covering materials. Tile construction typically includes a porcelain or ceramic tile adhered to a substrate surface with an adhesive, and borders surrounding the tile are filled with grout. Such typical tile construction is rigid and durable when it is stable. However, a substrate can be less than perfectly stable. If a substrate flexes or shifts or people or objects move across the floor, grout and/or the adhesive binding the tile to the floor can crack and break, leading to loose or broken tiles.
Standard tile configurations include rigid grout adhering tile to substrate. Such rigid grout easily transmits sound waves from the tile to the substrate and vice versa. Similarly, rigid grout rigidly holds the tile in place. In the event the substrate is uneven or flexible, both the tile and the grout itself are subject to breakage and accelerated wear when weight is applied to the tile.
A dampened tile is disclosed, providing comfort, sound deadening, and ease of installation and removal. The tile includes a porcelain tile and a flexible dampening material applied between the tile and an adjoining surface. The flexible dampening material can be a number of different polymer or foam materials. The flexible dampening material can be applied to a bottom of the tile, sides of the tile, and pre-applied to a substrate surface below the tile.
One or more embodiments will now be described, by way of example, with reference to the accompanying drawings, in which:
Porcelain tile and ceramic tile are a rigid materials. When stably supported, the tile can be strong and durable. If the floor or slab under the tile moves, shifts, or is otherwise unstable, movement between the tile and the floor can damage the tile, the adhesive between the tile and the floor, and the grout surrounding the tile.
A dampened tile is provided utilizing a dampening material applied to lower surfaces if the tile. In one embodiment, the dampened tile is an encapsulated tile, with all sides of the tile coated in the dampening material except the visible surface of the tile. The dampening material can be provided upon the tile at a manufacturing location and shipped and sold to the consumer with the dampening material pre-applied. In other embodiments, the dampening material can cover only the sides or only the bottom of the tile. In other embodiments, the dampening material can be applied away from the manufacturing site or by the consumer. In other embodiments a dampening layer of material can be used in place of or in addition to dampening material applied to the tile.
Exemplary dampened or encapsulated tiles of the disclosure, once installed, resist breakage due to non structural slab movement, they feel softer under foot, they feel warmer than hard set tile floors, less sound is transferred to below living spaces and in the same room. The dampened tiles are easy to install and care for. Using the tiles creates a forgiving system, if an installation error is made or an event ever takes place that would require removal of the tiles this can be done easily and tiles can be replaced once the issue has been corrected.
The disclosed tiles are suitable for residential or light commercial installations, defined as areas where the system is subject to foot traffic or light pneumatic wheeled carts. However, flex and dampening properties provided by the disclosed system can cause force that would normally be distributed across an entire tile or a plurality of tiles to be concentrated on a portion or point of a tile. Care should be taken to avoid using the tile where hard metal or plastic solid wheel carts are utilized. Similarly, heavy point loads exceeding the tiles expected breaking strength requirements should be avoided. The disclosed tile system is not suitable for forklift, pallet jacks, or wheeled traffic of heavy loads or other areas whereby the tiles will be subject to extra heavy load requirements. Care should be taken not to exceed load requirements specified by manufacturers of tiles used or coated as disclosed.
In some embodiments, tiles utilized should be of the highest quality impervious porcelain body, less than 0.5% absorption tested under ASTM test methods. In one embodiment, tiles must be a thickness of 9 5 mm (⅜″) or greater. In one embodiment, tile thickness between 10 and 12 mm is recommended. Under some conditions, tile with small or no deviation in thickness within the tile provide best results. Exemplary tiles for use with the disclosed system should be flat in all aspects, across the face and edges with no wedging or warpage. Such exemplary tiles should be first quality under ANSI A137.1-2008. Under some conditions, all edges should be rectified to provide strait 90 degree edges and a single calibration per lot size.
A floor substrate must be clean and free of debris in preparation for installation. Any floor suitable for a standard thinset application of tile are acceptable with the following restrictions. Floors must be flat and not have deflection greater than ⅛″ in 10 feet. There must be no transitional heights or structural defects to be bridged which would allow upward or other unstable movement under the tiles. The tiles must be tight fit within the field of tiles and at all edges to restrict movement. Use of high quality silicone can be utilized at the outside edges of the tiles to restrict movement of the tiles where there is no wall structure or other edge surface containing the outside tiles. One can use metal or other tile edging transitions known in the art to transition from the tiles. One may bond transitions to the floor to hold tiles firm on their edges. Glue transitions to the floor to hold tiles firm on edges are recommended, with double stick carpet tape or epoxy bond transition strips.
Tiles may be cut to size. One may use scoring tools or a wet saw according to normal tile cutting practice.
Cutting, with scoring tools or wet saw, can be used as are known in the art to cut tiles.
Care of the tiles can be performed according to a number of envisioned processes. Edges may be heat sealed to enhance water perm performance. Mop tiles with light mopping is recommended, as flooding surface should be avoided. If flooding has taken place, and water or cleaner removal is desired pick-up tiles, clean or dry then reset. If heavy cleaning is required to remove contaminants from below the surface of the tiles, pick-up those affected tiles and clean and replace. For care of the specific tiles, one may follow manufacturers recommended instructions.
Dampening materials or coatings as disclosed herein can take any of a number of embodiments. Closed-cell foam, such as exemplary ethylene propylene diene terpolymer (EPDM), is one exemplary product that can be utilized. Open-cell foam is another exemplary product that can be utilized. A rubberized layer or polymerized spray on coating can additionally be utilized. A desirable dampening material is durable and can accept the loading and temperature ranges seen in normal flooring applications. Such a material meets all regulations and codes for safe use around persons. Such a material tends to be flexible, providing elasticity even after the tile is installed to a surface and abutted to other neighboring tiles. Such a material holds up to light cleaning and mopping without absorbing water or other liquids.
According to one exemplary embodiment of dampening materials, Nitto provides 5790S-series dampening tapes, which are single coated foam tapes These dampening tapes are based on a cross linked polyolefin foam, coated with pressure sensitive adhesive, and having excellent bonding properties, especially on low energy surfaces. In one embodiment, the tape includes a polyolefin foam carrier top layer, a modified acrylic adhesive middle layer, and a paper release liner bottom layer. Nitto 5790S-series are single-coated foam tapes known in the art with excellent adhesion properties on a wide range of materials such as plastic, steel, and glass. The flexible foam carrier conforms easy to the irregularities of the substrate and provides impact resistance, thermal insulation, sound dampening and sealing properties. Nitto 5790S-series tapes are used in other applications as a gap filler to absorb sound and to seal against dust and humidity. Exemplary tape thicknesses include 0.6 mm and 1.1 mm.
One exemplary particular appliqué can include a particular version of the Nitto 5790S-series dampening tape, disclosed herein. Nitto 5790S10 foam is provided in an exemplary 1300 mm width. In accordance with the present disclosure, this material can be provided as a flat foam product with adhesive pre-applied to the foam with pull-away paper backing preserving the adhesive prior to attachment to the tile. The 1300 mm wide product can be easily cut to size for application to the tile. This particular tape is exemplary of foam tape that can be utilized according to the disclosure, although a number of different foam tapes and other materials can be similarly used. The disclosure is not intended to be limited to the particular examples provided
The disclosed tile system enables use of a temporary display construction method in accordance with the disclosure. Any merchant may quickly and inexpensively set up a temporary tile floor that seems to be a permanent construction. Exemplary show booths can be set up for exhibitions, outdoor markets, and fairs. The result is an easy to clean, durable, hygienic temporary surface. An exemplary restaurant, coffee shop, or bar could set up flooring on a sidewalk or parking lot for a one day summer fair or sporting event, providing customers with a professionally crafted tile floor, and then the temporary floor can be easily removed after the event. An exemplary bar could set up a tile surface on an outside wooden deck. A restaurant with a damaged floor could place the disclosed tile system over the damaged floor until the repairs can be arranged in order to remain open in the meantime. A number of exemplary uses of the disclosed system are envisioned, and the disclosure is not intended to be limited to the examples provided.
An exemplary process for installing a temporary floor for a booth or a temporary kiosk includes selecting a sufficiently flat substrate surface; thoroughly cleaning the flat surface; applying a rubberized or polymerized sheet (if one is being used in addition to or in the alternative to a tile with dampening material applied to the bottom of the tile;) laying down untreated tile upon the sheet or laying down treated dampened tile according to the disclosure; securing side tiles of the floor pattern (using an adhesive such as silicone or using a transition bracket or transition strip;) using and cleaning the surface for the commercial event or activity; removing the tile and associated transition materials; removing the sheet from the substrate if applied; and cleaning the substrate surface according to methods known in the art.
In addition to commercial uses, the disclosed tile system can be used in temporary, permanent, or semi-permanent residential flooring applications. For example, the disclosed tile system could be used on outdoor and backyard to cover a cement patio or a wood deck or even a grass area (meeting the flatness requirements) around pools and gazebos. If a wedding reception were being held at a house, an outside patio could be turned into a tent area with a fine tile floor which could be removed the next day. If a kitchen floor includes a fairly flexible wooden surface that would cause normal grout to crack and fail under normal use, the disclosed tile could be used to provide a tile surface over the wooden surface. A number of exemplary uses of the disclosed system are envisioned, and the disclosure is not intended to be limited to the examples provided.
The disclosure has described certain preferred embodiments and modifications of those embodiments. Further modifications and alterations may occur to others upon reading and understanding the specification. Therefore, it is intended that the disclosure not be limited to the particular embodiment(s) disclosed as the best mode contemplated for carrying out this disclosure, but that the disclosure will include all embodiments falling within the scope of the appended claims.
This disclosure claims the benefit of U.S. Provisional Application No. 61/984,105 filed on Apr. 25, 2014 which is hereby incorporated by reference.
