Description

Walk-on insulation system

Technical field

The invention relates to a system of walkable insulation, in particular walkable soil insulation, according to the preamble of claim 1.

BACKGROUND OF THE INVENTION

At present, mineral wool insulations, such as those available under the trade names Isover ORSIK, UNI, ORSTROP, are generally used as insulating materials for thermal insulation of the soil.

If such soil insulation is to be walkable, then a supporting structure must be provided for attaching the walkable slab above such insulation. According to the state of the art, such a support structure is currently made of wood panels or OSB boards (pressed boards of oriented chips), which are assembled in crosses. Insulation material is placed between these crosses and the desired walkable board can be laid up. An example of such a system is the “TOPKOMFORT” system offered by spol. Saint-Gobain ISOVER Austria GmbH upon request.

However, due to the increasing demand for thermal insulation, especially in modern ecological and passive buildings, wood can no longer be considered as a sufficiently insulating material, and the load-bearing structures thus de facto constitute an undesirable thermal bridge. Another disadvantage of such a construction is also its high weight and relatively high laboriousness in the processing of wood or OSB board elements. Another disadvantage is the price of OSB boards of crosses.

The essence of the technical solution

The object of the present invention is to overcome the above-mentioned disadvantages of the prior art. In particular, it is an object of the present invention to provide a system for walkable soil insulation, the supporting structure of which would not constitute a thermal bridge, as in the prior art.

According to this technical solution, the supporting structure for fastening the walkable board is made of polystyrene, and preferably it is made of crosses composed of polystyrene plates and polystyrene beams, on the top side of which the wooden strips for fastening the walkable board are preferably attached. Preferably, all of the space around the support structure is filled with a thermal insulating material and the entire system has a vapor-tight foil disposed at least on the underside to protect it from moisture.

The use of polystyrene instead of wood or OSB eliminates all thermal bridges, as polystyrene has about five times better insulation properties than wood or OSB boards at very good affordability.

In addition, polystyrene is very easy to process, which facilitates and speeds up the installation of such a system. In particular, it is possible to very easily compensate for any unevenness by simply grinding foam polystyrene, the so-called EPS polystyrene.

Finally, polystyrene is also lighter than wood or OSB boards, which also facilitates assembly, while reducing the weight of the entire walkable insulation system and less stressing the ceiling construction.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution will be explained in more detail with the help of figures showing a specific exemplary embodiment, in which it represents:

Fig. 2 shows an assembled EPS grate consisting of crosses and beams, Figs. 3 and 4 fixing the strips for attaching a walkable board, Figs. 5 and 6 of mineral insulation insertion, and Figs. 7 and 8 laying a walkable board.

Examples of technical solution

An example of walkable insulation according to this technical solution is the upcoming system STEP CROSS of the Isover division of Saint-Gobain Construction Products cz as, designed for the isolation of walkable soil.

The vapor-tightness of this system is ensured by Isover VARIO KM DUPLEX UV foil with accessories (Isover VARIO KB1, Isover VARIO MultiTape SL, Isover VARIO DoubleFit), which is arranged on the entire surface from below and on the sides of the insulation system.

Supporting crosses are made of EPS 150S 100 x 500 x height of choice 200 to 300 mm (Isover Cross EPS). Thanks to the pre-cuts, they are easy and fast to fit in the cross, see Fig. 1.

These crosses are interspersed with beams of EPS of the same thickness and height (Isover TRAM EPS). EPS joints can be glued with PUR glue for better handling, eg Den Braven Kleber Wood.

The grid of the supporting structure i is assembled to a clear width of 595 mm, which is ideal for inserting insulating material 2 with a width of 600 mm (Isover ORSIK, UNI), see Fig. 2.

Any unevenness can be easily compensated by grinding EPS.

The entire length of the EPS construction (ie through EPS crosses and EPS beams) is applied with a special PUR glue for joining EPS with wood, connecting EPS construction with wooden strips 4, here boards of 100 mm width, for fixing the walkable board 3, see Fig. 3 and 4.

The grid of the supporting structure 1 assembled in this way is interspersed with an insulating material 2, for example Isover ORSIK, UNI, ORSTROP mineral insulation.

With the correct dimensions, ie the aforementioned clear width and suitable length of EPS beams, the mineral insulation can be inserted without cutting. However, it is preferable to lay at least two layers on the bond - in this case, the insulation must be halved to cover the joints (no further cut to size is required), see Fig. 5.

Mineral insulation should also be used to fill any remaining spaces between the crosses and the side wall gaps, see Fig. 6.

It is recommended to fold the system with OSB boards of 22 mm thickness on tongue and groove, fixed to ensure stability by screws 4 x 45 mm 4 to 5 pieces per running meter, see Figures 7 and 8.

However, it is also possible to use any other flap, such as chipboard multifunctional boards, so-called MFP boards, classy, planks, etc.
