Definitions

  • the invention relates to a thermal insulation system for a building envelope, with at least one insulating panel having at least one vacuum insulation panel.
  • Thermal insulation reduces the passage of thermal energy through a component.
  • the targeted use of insulating materials on the building can reduce the use of heat energy to a minimum.
  • heat energy come also the economic motives (with rising energy prices).
  • there are different approaches to save energy This includes, inter alia, a reduction in the energy requirement, which means e.g. to reduce the heating in unused rooms.
  • an increase in efficiency can be achieved by e.g. Heat recovery or, as already mentioned, by a very good thermal insulation. Investing in insulation that results in higher energy efficiency is particularly worthwhile in the areas of walls and roofs, since here the largest components are present on the building.
  • the heat contactor on the building envelope offers the greatest savings potential.
  • the heat transfer coefficient U is defined as follows: wherein the heat transfer resistance R is formed in a simplified representation of:
  • R se external contact resistance in m 2 -K / W
  • R S i internal contact resistance in m 2 -K / W
  • VIP vacuum insulation panels
  • the very low thermal conductivity, for example, 0.008 W / m-K (as a design value) of such vacuum panels has a great advantage in use in construction.
  • the component height remains extremely low compared to constructions with conventional insulation materials.
  • Thermal insulation systems with VIP for the rafter insulation with the lowest construction height are suitable, for example, for the subsequent insulation in the case of renovation.
  • the thermal conductivity level of the VIP used should be between 3 and 10 m W / mK, more preferably between 6 and 8 m W / mK.
  • the serious influence of the thermal conductivity of the insulating material is shown by a simple example of a roof structure (in the calculation of the insulation thicknesses according to DIN): with a 100% coverage of an exemplary roof surface with PUR (WLS 030) or VIP (WLS 008) and a desired U-value of, for example, 0.20 W / m K, a thickness of 5.5 cm is required for insulation with PUR panels, whereas only 1.5 cm in height would be required for VIP board occupancy.
  • VIP as insulating elements have some special features when used in construction.
  • a major problem is that the elements are not freely cut to size. This main problem means that transitions to other components must be accurately sized and then the VIP ordered to size. Otherwise, gaps between the VIP and the adjacent component remain open, resulting in thermal bridges at the sites concerned.
  • VIPs on the surface are sensitive to damage to the high-barrier film. Scratches from splinters or stones on the surface of the components, falling tool or building material almost always result in severe damage to the high-barrier film and thus the loss of vacuum, coupled with a strong reduction in insulation performance.
  • VIPs can not be fixed by conventional fasteners such as screws or nails. Elaborate constructions or special penetrations formed in the VIP manufacturing allow the systems on the market to be attached. Alternatively, when used on the wall, the VIP is glued over its entire surface. This full-surface bonding can not be used in an application, for example, on the roof, if there is no full-surface formwork.
  • Object of the present invention is to provide a thermal insulation system of the type mentioned, especially for use on the pitched roof or a facade, available that can be easily and quickly fastened, at the same time the risk of damage should be reduced.
  • auxiliary battens as an integral part of the insulation board for connection intended for the underground.
  • the auxiliary battens which is preferably arranged next to or in a plane with the VIP and firmly connected to this, in particular glued, it is possible to attach the entire insulation board in a simple manner.
  • the insulation board can be attached by screws or nails to rafters of a roof or in the case of a facade on a wooden stand. It is understood that the insulation board on the auxiliary battens, which is an integral part of the insulation board, can be attached to any surface.
  • the thermal insulation system is mounted on a pitched roof, that the auxiliary battens is arranged at right angles to the rafters, so runs horizontally.
  • the auxiliary battens is then possible to fasten the system safely and easily on objects with different rafter spacings.
  • the present invention then also relates to a building envelope with a thermal insulation system of the type in question.
  • a marking indicating the course and the arrangement of the auxiliary battens be provided on its outside.
  • This marking can be formed for example as a colored edge and / or a change in the surface structure.
  • Such a profile has the advantage that the laying of further insulation boards is considerably facilitated by the receiving profile, as laid for laying the adjacent insulation board only with its lower, the auxiliary battens opposite end face in the receiving profile and then attached itself via its own auxiliary battens. In this way, a secure attachment results on opposite sides of the insulation board.
  • an insulating board with an auxiliary battens has only one VIP.
  • an insulating board with a Hilfslattung having a plurality of VIP.
  • the individual VIPs can be arranged side by side in a row. But it is also possible to arrange a plurality of rows with one or more VIP.
  • the division into several VIP segments has the advantage that, first of all, only one segment is ventilated in the event of unintentional damage to a VIP, while the undamaged segments continue to function. In certain applications, such as hipped roofs, it may be necessary that the thermal insulation system or the relevant peripheral insulation board must be cut accordingly. With segmented VIP or a plurality of VIP, the necessary cutting can then take place, so that only the cut VIP is ventilated.
  • a rail system is provided to solve the aforementioned object, having a plurality of rails to be arranged in parallel, each rail has at least one longitudinal side a longitudinal receptacle for inserting an insulating board and wherein the length of a rail the multiple of the length of an insulating board corresponds, so that at least two insulation boards are used in a pair of rails.
  • the rails are fastened to each other at the necessary distance to the rafters and form a slot, in which the individual insulation boards of the thermal insulation system are sequentially and in particular without intermediate separation threaded.
  • the rails can in principle be arranged in the longitudinal direction of the rafter, but preferably transversely thereto. the.
  • the arrangement of the rails transversely to the rafter longitudinal direction has the advantage that the width of the insulation boards is ultimately independent of the rafter spacing.
  • the immediate arrangement of the insulation boards side by side within the rail system lead straight with appropriate overlapping edge formation of the insulation boards, which will be discussed in more detail below, to heat losses are kept very small at the junctions of adjacent insulation boards.
  • the following features relate to the heat system according to the invention, regardless of whether an auxiliary battens for attachment or a rail system is provided.

  • a marginal section from a compressible to provide the same material, in particular of a soft PU foam.
  • the possibly multiple overlapping of the edge design in the form of a stepped rebate or a tongue and groove connection as well as by the soft compensating material prevents increased energy exchange at the joints.
  • the edge may consist of two VIPs bonded to one another with a surface protection layer made of PUR, IPX or XPS.
  • a protruding protective layer may be provided, which may consist of PUR, EPS or XPS. In any case, increased heat transfer at the joints of the individual elements are avoided by such edge designs.

  • the VIP should be designed so that the pressure increase in the VIP between 0.3 to 3 mbar / year, preferably 0.5 to 2 mbar / year, so that there is a long period of use.
  • Insulating boards with the aforementioned dimensions initially have the advantage that they are still manageable on the roof and at the same time have only a few joints per unit area to adjacent insulation boards.
  • insulation boards of such a length especially in connection with the auxiliary battens, offer the advantage that they can be attached to at least two rafters. As a result, a secure attachment is ensured in each case in connection with the auxiliary battens.
  • the thermal insulation system according to the invention has at least two insulation boards with different sized plate sizes.
  • a system of different plate sizes allows the optimum utilization of the area to be occupied.
  • a system of each of the halved plate sizes be used. For example, two to five different plate sizes may be present, preferably two to three different plate sizes should be present.

  • the thickness of the auxiliary plates is between 5 and 200 mm, preferably between 10 and 100 mm and particularly preferably between 20 and 70 mm.
  • the degree of coverage of the auxiliary plates should be kept as low as possible, since the poorer thermal insulation properties of the material of the auxiliary plates increases the total U-value for the insulated component.
