Description

Wood floor moisture-proof film for floor heating

Technical Field

The utility model relates to a dampproof membrane technical field that timber apron and timber apron heating were used especially relates to a timber apron dampproof membrane that flooring heating was used.

Background

The floor heating is a heating system end form which lays a pipeline or a heating cable which is communicated with hot water in a building cement cushion layer or a dry laying module on a building floor slab to heat upper layer ground materials so as to heat the indoor.

With the improvement of the social and economic development level, floor heating is widely applied not only in the traditional heating areas in the north but also in the non-traditional heating areas in the south. Meanwhile, the wood floor is also a widely used floor material for families. The floor heating industry and the wood floor industry develop products from the industry perspective, and the products at the intersection of the floor heating industry and the wood floor industry and the application technology are not sufficiently emphasized, so that the following problems occur when the floor heating industry and the wood floor are combined and applied: the insufficient room temperature, the uneven room ground temperature and the increased energy consumption of the floor heating system can even cause the overheating of heating cables and cause safety risks in some special applications of floor heating, such as the dry pavement of electric floor heating.

The main reason for the above problems is that, when the wood floor is paved, in order to prevent the water vapor in the floor structure layer from permeating upwards and causing damage to the wood floor, and simultaneously, in order to eliminate the noise caused by the contact between the wood floor and the next floor structure and to maintain the proper elasticity of the bottom plate, the feeling when treading is improved, before the wood floor is paved, a layer of moisture-proof film needs to be paved between the wood floor and the lower floor structure. The moisture-proof film has the effects of moisture proofing, noise reduction and improvement of the feeling during treading, and also has the effect of correcting the slight unevenness of the local ground in actual installation, so that the condition that the wood floor is partially hollowly is prevented. This moisture barrier is therefore typically a flexible foam film and has a thickness of around 2-5 mm.

The moisture-proof film is based on physical characteristics, and the moisture-proof film has certain heat preservation and heat insulation characteristics objectively while finishing the main functions of moisture prevention, noise reduction and the like.

When the room adopts floor heating and uses wood floor, because the moisture-proof film has certain heat preservation and heat insulation performance, the wood floor above the floor heating can not be fully heated, and the room temperature is not enough. Meanwhile, the moisture-proof film increases the thermal resistance of floor heating to the heat transfer of the room, so that more heat flows are transferred to the room below the building, and the energy consumption is increased. In water floor heating, higher supply water temperatures have to be used to reach the room temperature, leading to a further increase in the energy consumption of the system. In some specific floor heating applications, such as dry-type floor heating, the moisture-proof film can raise the working temperature of the cable, shorten the service life of the heating cable, and even cause safety risks such as overheating.
