Abstract

Thermal/acoustic/vapour insulation barriers for floor coverings such as wood, vinyl, cushion, carpets and rugs, tiles, ceramic tiles, flocked substrates or bricks incorporate a reflective surface that reflects more than 80% of total radiation that passes in and though a floor-covering to the area/ground or medium beneath it. The invention is particularly but not exclusively a foam (e.g. polyethylene or polypropylene or polyester), crumb or latex rubber, non-woven felt or woven or knitted substrate that has one or both sides covered with a reflective surface such as a metallised polyester or aluminium foil. A woven, knitted or non-woven backing may be present.

Description

Therma-Lay Reflective Thermal Insulation Barrier and Staticl Anti-Static Dissipation/insulation Under-lay Materials for Floor Coverings Patent Application Description The present invention relates to articles offering reflective thermally insulating properties, particularly but not exclusively, closed cell foams (such as polyethylene or crumb rubber, non-woven and felt substrates, that have one or both sides covered with a reflective surface, as well as for woven, knitted and non-woven substrates or a combination of each, consisting of yarns, filaments or fibres that are either polypropylene or a combination of fibres that may also have thermo-plastic properties, which are also covered or coated with a reflective surface to produce energy efficient articles for conserving warmth, that act as an insulation barrier to prevent heat energy escaping through a floor covering by radiation, conduction or convection.
These substrates can also be a combination of an open or a closed-cell foam or crumb-rubber, non-woven or felt underlay product that have on one side a woven or knitted or non-woven substrate that acts as a backing, a metallised polyester or aluminium foil is sandwiched or where the underlay or primary has been sprayed or coated with reflective metallised particles or paint or pigment.
The concept of the invention is to produce a reflective thermal insulation barrier in floor coverings and for use in conjunction with other flooring systems such as wood (parquet), vinyl, cushion, carpets and rugs (woven, tufted or non-woven), carpet tiles, ceramic tiles, flocked substrates or bricks, by incorporating a reflective surface that reflects ore than 80% of total radiation that passes in and through a floor-covering to the area/ground or medium beneath it. With this invention, it is possible to conserve heat energy within a room or area by creating this form of insulation barrier between the ground or area under the floor-covering, or substrate under the floor covering, and the air in the space above the floor covering, i. e. the room.
This reflective thermal insulation barrier can, in accordance with this invention, be a foam or crumb-rubber or non-woven felt, and has either one or both sides laminated or covered with a reflective surface that may be a metallised polyester or aluminium foil or that may have been sprayedlcoated with a highly reflective paint or similar product offering high reflective properties. This underiay, therefore, offers substantial advantages in thermal insulation as the underlay acts as an insulation medium against convection and conduction, whilst the reflective surface also acts as a means of reflecting radiation back into the room, instead of the heat/radiation penetrating and being lost through the floor-covering and through the underfay.
The invention also refers to the underlay being coated/covered on both sides. This is in order that the cold and moisture from the ground or base material under the floor covering (e. g. concrete or bitumen) is reflected back into the ground to prevent the cold coming through the underlay and/or the floor-covering. The reflective surface, therefore, also acts as a moisture and vapour barrier.
Uses: Aircraft, stadiums, cars, buses, houses, hotels, offices, hospitals.
Various types and thickness of primary-, secondary-backings and underlays for floorcoverings are used with emphasis and provide a cushion for the floor-covering to sit upon to help maintain its appearance and reduce wear. No primary-, secondarybackings or underlays address the problem of radiation passing through the floor covering and on through the underlay, by using a reflective mediumilayer/coating to create a thermal efficient floor-covering.
