Abstract

The insulation includes an aluminium foil or metallised polyester film, laminated or bonded to another material. Preferably the other material comprises non-woven (needled or stitch bonded) fabric comprising wool and recycled fibres, or cross-linked polyolefin. Preferred insulation includes outer layers of recycled rubber crumb or latex, embossed polyester or polypropylene foam, creep resistant fabric, or reflective material, optionally treated with anti-fungal agents. The insulation may include trapped air. The insulation can be placed beneath carpets, linoleum or hard wood floors. It could also be used as a wall or loft thermal and acoustic insulator, or as an electrostatic discharge material.

Description

Therma-Float Reflective Thermal/Vapour/Acoustic Underlay Insulation Barrier for Floor Coverings and for Wall and Loft Insulation.
Patent Application
Description
The present invention relates to articles offering reflective thermally insulating properties, particularly from sheet materials made from non-woven and felt substrates (predominantly nonwoven) that are backed with crumb rubber or closed cell foam (such as polyethylene or crumb or latex rubber, that may also have on one or both sides covered with a reflective surface, as well as woven, knitted and non-woven substrates or a combination of each, consisting of yarns, filaments or fibres that are either glass or 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 a thermal insulation barrier to prevent heat energy escaping through a floor covering by radiation, conduction or convection, as well as providing acoustic insulation.
These substrates can also be a combination of an open or a closed-cell foam, latex 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 more than 80% of total radiation that passes in and through a floor-covering to the area/ground or medium beneath it. The substrate will also act as a vapour barrier. 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, crumb or latex -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 sprayed/coated with a highly reflective paint or similar product offering high reflective properties. This underlay, 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 underlay.
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.
