Production industrial heat insulating and sound insulating materials

Thermal insulation is the reduction of heat transfer i. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced or thermal radiation is reflected rather than absorbed by the lower-temperature body. The insulating capability of a material is measured as the inverse of thermal conductivity k. Low thermal conductivity is equivalent to high insulating capability Resistance value.

Building insulation

VIDEO ON THE TOPIC: CTK - production of car deadening & soundproofing materials

The present invention relates to a non-woven synthetic sheet material for use in sound and thermal insulation and wherein the synthetic sheet material or felt is formed of a uniform synthetic fiber mat which is needle-punched and wherein, preferably but not exclusively, a metalized polyethylene film may be secured to a surface thereof by a further needle punch step. The synthetic sheet material is preferably used in the construction industry to insulate floors, walls, and other surfaces and to also insulate several construction materials, such as pipes or domestic appliances to thermally and sound insulate them, such as a covering for a dishwasher.

Sound absorbing materials for use in the construction industry are known and many of these utilize rubberized materials or cork. We usually find these materials as a sub layer in the construction of floors or partition walls. These materials are also susceptible to damage when stored on a construction site where there is a lot of activity.

Also, the material can detach along the layered surfaces. It teaches the consolidation of the composition layers by the use of needle-punching. Needle punching binding has been known in the art for quite some time. However, there is a need to provide a similar material and which is homogeneous throughout and providing good mechanical properties, in all directions, thereby resisting decomposition or splitting during application and use and which can further provide insulating and acoustical properties without having the need to be incorporated into a multi-layer structure and without having to impregnate the synthetic fibers with chemical products.

With the advent of higher population density in urban areas there is a desire to insulate dwellings and offices to provide better sound absorption.

Occupants of such buildings are more and more exposed to sounds by a multitude of environmental noise-generating sources such as televisions, congregation of children, radio, sound systems, electrical tools, telephones, traffic noise, and noise generated by walking on hard floor surfaces for example.

In order to enhance the environment of the occupants of these buildings and offices new building codes have been applied. These codes place a restriction on the intensity of sounds to be generated in a an occupied environment. At the same time research is being done in order to diminish the cost of sound absorbing material while maintaining a high sound absorption performance. In view of the above, there is a need to provide a new material, at low cost, which is easy to install and which is efficient in attenuating sound.

There is also a need to provide a material which is also sound and thermal insulating. It is therefore a feature of the present invention to provide a non-woven synthetic sheet material which is needle-punched and which is homogeneous throughout and provides good mechanical properties, in all directions, to resist decomposition or splitting during application or use, and which further provides for excellent sound insulation and which can be fabricated in different density depending on the intended use of the material.

According to the above features, from a broad aspect, the present invention provides a non-woven synthetic sheet material for use in construction for sound insulation. The sheet material is a felt of synthetic fibers of substantially uniform thickness and defining opposed flat surfaces. The sheet material is needle-punched from at least one of the opposed flat surfaces thereof to cause the synthetic fibers to intertwine to form a pliable sound insulating sheet.

According to a further broad aspect of the present invention there is provided a non-woven synthetic sheet material for use in construction for thermal insulation. The sheet material is needle-punched from at least one of the opposed flat surfaces thereof to cause the synthetic fibers to intertwine to form a pliable thermal insulating sheet. A preferred embodiment of the present invention will now be described with reference to the examples thereof as illustrated by the accompanying drawings in which.

Referring now to FIG. The sheet material 10 is a felt or mat having a substantially uniform thickness of synthetic fibers 11 and defines opposed flat surfaces, namely a top surface 12 and a bottom surface The sheet material 11 is maintained homogeneous by needle punching, not shown herein but well known to a person skilled in the art, whereby the fibers intertwine together to maintain a homogeneous consistency.

The sheet 11 may be formed to be very pliable permitting it to be rolled about curved objects such as plumbing conduits that generate noise due to the circulation of water therein, curved surfaces, the insulation of irregular shaped enclosures such as sound generating construction appliances, etc.

The top sheet layer 11 also preferably has a thickness of from 0. The complete thermal acoustic sheet 10 as shown in FIG. At the outlet of the machine the fiber mat is subjected to a needle punching process and this may be effected by a plurality of needle rolls. A film is then deposited over the mat and on the top flat surface thereof and again the mat and the polyethylene film are subjected to a further needle punch process.

During this further stage the sheet becomes more rigid due to the fact that fibers in the top portion of the fiber layer 11 are caused to rise through the orifices formed in the polyethylene sheet to cause the sheet to be interconnected with the top surface layer.

As described above, depending on the application of the non-woven synthetic sheet material it may not be necessary to interconnect a polyethylene sheet on the top surface of the mat. For example, as shown in FIG. The synthetic sheet material mat in either of its forms, either with or without a polymeric film attached to its surface may also be glued on a concrete slab as shown at 19 in FIG.

As shown in FIG. A utility for such strips is shown in FIG. When the product is in strip form as shown in FIG. Also, the polymeric sheet 14 may also be secured to the top surface 12 but this is most likely not necessary for the application as above described. The polymeric film could also be replaced by a thin aluminum sheet adhered to the surface by needle punching or other means. The thickness of the synthetic sheet material in usual residential or commercial building structures is between 1 and 15 mm and preferably between 4 and 6 mm when utilized in applications as illustrated in FIGS.

In the installation of the sheet material when utilized as a sound insulating sheet, the sheet is cut to the proper size of the floor surface to be insulated. The cutting of the sheet can be done with scissors normally used for cutting carpeting or an Exacto knife as is well known in the art. The insulating sheet material can be simply laid down on the surface or else glued on the surface or simply disposed on objects, such as the floor joists Following are examples of methods of use of the non-woven synthetic sheet material for sound and thermal insulation.

The surface is a concrete floor surface to which it is desirable to secure a ceramic tile floor. The non-woven synthetic sheet material of the present invention fabricated with or without a polymeric film is applied to the concrete surface.

A plywood sheet material is applied on the top surface of the synthetic sheet material or on the polymeric film if secured thereto. Ceramic tiles are then applied to the top of the plywood sheet using standard practice. In this application the synthetic sheet material, in strip form, is disposed on the top surface of floor joists and the bottom surface of the floor sheeting material is secured to the floor joists by fasteners, as is well known in the art. Thus, the sheet material strip provides vibrations and sound damping between the floor sheeting and support joists.

The non-woven synthetic sheet material has a metalized polyethylene film sheet and it is glued directly on a concrete wall surface to provide sound and thermal insulation. The non-woven synthetic sheet material is glued directly on a partition wall formed of concrete blocks to sound insulate two dwellings. Nailing strips are then secured over the synthetic sheet material to support a finish wall board surface, preferably a gypsum board and this is applied to both sides of the concrete block wall to provide a double insulating layer separated by air and the concrete blocks.

Accordingly, excellent sound damping is achieved. A non-woven synthetic sheet was constructed in accordance with the present invention and formed of a synthetic fiber sheet of substantially uniform thickness and having a polyethylene film attached to one of its opposed surfaces. This sheet material was tested by Architectural Acoustic Lab 3D according to the following test parameters.

The parameters of the instrumentation utilized were CEI : using filters of an octave and half octave frequencies and other octaves, which are used to analyze sound and vibrations. The characteristics of the test apparatus utilized for the experimentation are setforth in the enclosed table:.

Handbook of Ecomaterials pp Cite as. Global population growth and economic growth increase the demand for more buildings and thus more construction materials. Increases in production of construction materials lead also to greenhouse gas emission rise and depletion of natural resources. One of these materials is insulation, which increasingly plays a vital role in the energy performance of buildings and in the process reducing negative environmental impacts of the built environment. A number of studies have focused on finding substitutions for petrochemicals as a source for manufacturing building insulation. Some investigations have identified insulation materials that have lower environmental costs, for example, those that are made of natural or recycled materials. Manufacturing building insulation from agricultural by-product s is one such approach. However, these are in their early stages of development, and there is a long way to have them on the market. Alongside identifying matters that require additional research to enhance technical reliability, this study explores issues that can improve the market viability and help make natural and recycled materials more attractive alternatives. There are some common themes among these materials and earlier studies have revealed that each of these agricultural wastes has some advantages that can be exploited for specific purposes alongside disadvantages that must be overcome.

The most commonly used mineral insulation materials were glass fibres, rock wool, asbestos, cellular glass, and expanded perlite and vermiculite. Synthetic insulation materials, such as expanded polystyrene (PS) and polyurethane foam (PUR), revolutionized the insulation market after they appeared in the s.

Thermal insulation

It is important to know how heat is transferred in fish holds. Heat is transferred by conduction, convection or radiation, or by a combination of all three. Heat always moves from warmer to colder areas; it seeks a balance. If the interior of an insulated fish hold is colder than the outside air, the fish hold draws heat from the outside. The greater the temperature difference, the faster the heat flows to the colder area. By this mode, heat energy is passed through a solid, liquid or gas from molecule to molecule in a material. In order for the heat to be conducted, there should be physical contact between particles and some temperature difference. Therefore, thermal conductivity is the measure of the speed of heat flow passed from particle to particle. The rate of heat flow through a specific material will be influenced by the difference of temperature and by its thermal conductivity. The rate of heat flow will depend on the temperature of the moving gas or liquid and on its rate of flow.
