A well-known example of this is shown in European patent 1,618,264. The insulation system shown herein consists of plastic shells filled with thermally insulating material. The trays are mounted with the open side down on supports on a roof.

An object of the invention is to provide an alternative insulation system.

SUMMARY OF THE INVENTION

The invention provides a building with a plurality of outer walls, wherein the outer walls are formed by a side wall, side wall or roof of the building, and an insulation system against at least one outer wall, the insulation system comprising a plurality of rectangular insulation cassettes 2, the insulation cassettes being a plastic container and comprise a separate plastic cover, wherein the tray has a bottom wall and a circumferential wall standing therefrom, which are formed as a whole and the cover closes the open side of the tray, wherein the tray and the cover are provided with mutually cooperating fastening parts for attachment of the lid to the tray, the bottom wall being on the side of the outer wall and the lid being placed on the top side of the tray facing away from the outer wall. The outer wall is defined herein as a wall that determines the outer shape of the building, not an internal partition wall or partition wall.

The assembly of the insulation system according to the invention can take place in parts, wherein first the trays are placed and then the lids are placed from the outside to form an air chamber in the insulation cassettes. This chamber contains a trapped volume of air so that thermal insulation is obtained. This chamber can also be fully or partially filled with thermally insulating and / or fire-resistant material. The chamber can also be used for the inclusion of electrical components or installation material. The covers determine the viewing surface of the insulation system and can thereby be adjusted as desired. The lids can be provided with different colors or decorations. The covers can be provided with additional functionalities, such as solar cells or lighting.

In one embodiment, the trough on the upper side of the circumferential wall remote from the bottom wall is provided with an insert strip, wherein the insert strips of successive trays engage with each other so that a good mutual cohesion is obtained. The insulation system therefore forms a very wind-resistant coherent whole.

In one embodiment thereof, the circumferential wall is formed with four circumferential wall sides which determine the rectangular shape of the trough, the upper side of at least one circumferential wall side being provided with a first insert strip, the first insert strip having a first free end which, in cooperation with the circumferential wall side defines a first receiving slot accessible in the direction of the bottom wall, and wherein the top side of at least one other circumferential wall portion is provided with a second insert strip, the second insert strip having a second free end which, in cooperation with the circumferential wall portion, moves in the direction of bounds the second receiving slot 10 accessible from the bottom wall, the first inserting frame and the second inserting frame engaging each other by receiving each other's free lips in the receiving slots. As a result, the trays can be brought into mutual relation by moving them one by one towards the outer wall, wherein the inserts 15 engage directly on each other.

In an embodiment thereof, the tray is successively provided in the circumferential direction with two first insert strips followed by two second insert strips, as a result of which the trays can be placed roof-tile and brought into relationship with each other.

In one embodiment, the lid is provided with a straight top wall with a rectangular main circumference, and a placement wall transversely thereto, which when placed in place of the lid comes in and against the peripheral wall of the container.

In one embodiment thereof, the fixing parts on the placement wall comprise hook parts distributed over the circumference and falling into hook-in openings in the circumference wall. The lid is clicked into place by the hook parts when placed on the tray.

In one embodiment thereof, the placement wall behind the hook parts is provided with hollow insert bushes into which, for example, a screwdriver can be inserted. A bending force can hereby be exerted on the insert bushes to locally release the hook parts.

In one embodiment the insert bushes are provided with a break port which gives access to the cavity of the hollow insert bushes from the side of the top wall. The break port keeps the top of the lid watertight until it is broken.

In one embodiment the cover is provided on at least one longitudinal side with a connecting edge which is lowered relative to the upper surface of the upper wall, wherein the cover is provided on at least one other longitudinal side with a protruding bearing edge, wherein the bearing edge of successive covers the connecting edge 10 connects to a flat joint top surface of the covers.

In an embodiment thereof, the cover is provided in circumferential direction along the longitudinal side successively with two connecting edges followed by two bearing edges, so that these can be placed roof-tile on the already mounted trays. The overlaps then provide a watertight drainage of rainwater.

In one embodiment, the insulation system is provided with mounting profiles extending parallel to each other, between which the trays are fixed, wherein the mounting profiles keep an air space free between the outer wall and the bottom of the trays. This air space can serve as a ventilation space behind the insulation cassettes.

In a simple to assemble embodiment, the mounting profile is provided with a hook rib and the peripheral wall of the trays at the transition to the bottom wall is provided with a hook edge which engages behind the hook rib. When inserting the trays, the hook rib snaps between the mounting profiles behind the hook edges thereof, whereby a firm attachment between the mounting profiles and the insulating cassettes is achieved.

In one embodiment, an air space is kept free between the wall and the bottom of the bins, the building being provided with an air treatment installation 35 which brings in air from the building into the air space. The indoor air is, for example, a fraction of the air that is constantly discharged to refresh the indoor air. This air has the temperature of the indoor space and by passing this air through the air space the wall itself gets the temperature of the indoor air. This results in an additional energy saving in the internal air treatment.

The invention further relates to an insulation system as mentioned above.

The aspects and measures described in this description and claims of the application and / or shown in the drawings of this application can where possible also be applied separately from each other. These individual aspects can be the subject of split-off patent applications that are aimed at this. This applies in particular to the measures and aspects described per se in the subclaims.

DETAILED DESCRIPTION OF THE DRAWINGS

Figure 1 shows schematically a building 1 of which a side wall 2, a flat roof part 3 and a sloping roof part 4 are shown. An insulation system 10 according to the invention is placed against the outside of the side wall 2 and on the upper sides of the sloping roof section 4 and the flat roof section 4. These have the same structure and will therefore be described in detail on the basis of the insulation system 10 against the side wall 2.

The insulation system 10 comprises a plurality of plastic mounting profiles 11 which are mounted parallel to each other against the side wall 2 at equal intervals. The mounting profiles 11 are preferably made from PVC (polyvinyl chloride). Other plastics are also possible, such as POM, HDPE or Nylon. Insulated cassettes 30a-30h are fixed between mounting profiles 11, of which only a few are numbered in this detailed description.

The mounting profiles 11 have an identical cross-section which is shown in detail in figures 3A and 3B. The mounting profile 11 shown has a straight, flat base strip 12 with upright support ribs 13 formed thereon. In the middle a coupling strip 15 extending transversely thereof is formed. On the coupling strip 15, a hook rib 16 and two retaining ribs 17, 18 have been formed from below, on both sides. The coupling strip 15 ends at the top in a wider supporting edge 19.

The insulating cassettes 30a-30h are identically shaped and in the attached state have the same spatial orientation. The insulating cassettes 30a-30h are shown in detail in section in figures 3A and 3B and the spatial orientation aspects in their mutual relationship are shown in figures 4A-5C. The insulating cassettes 30a-30h each comprise a plastic tray 40 with a plastic cover 60 thereon. The plastic tray 40 and the cover 60 are preferably made of PVC. Other plastics are also possible, such as POM, HDPE and Nylon. The tray 40 and the lid 60 can also be made of mutually different types of plastics.

The tray 40 comprises a straight bottom wall 41 which merges into four of these upright, contiguous circumferential wall sides 42 which define a rectangular main circumference. The rectangle is defined here by two pairs of parallel sides, the pairs being perpendicular to each other. The circumferential wall sides 42 comprise the same straight base wall 43 over the entire circumference, which at the transition to the bottom wall 41 is provided with an all-round, outwardly projecting hook edge 52 with an inclined ramp. The hook edge 52 is formed to hook behind the hook rib 16 of the fastening strip 11. Above this, on the base wall 43, a circumferentially extending, outwardly projecting fixation edge 51 is formed which fits between the two retaining ribs 17, 18 of the mounting profile 11.

Two circumferential wall sides 42 consecutive in the circumferential direction are provided with a staggered first top wall 45 which, via a staggering 44, merges into the base wall 43. On the outside of the first top wall 45, a first plug-in strip 46 is formed which has an oblong-accessible, elongated first receiving slot. 47 in which a flexible seal 80 is laid. The two circumferential wall sides 42 which follow in the circumferential direction are provided with a staggered second top wall 48 which, via the same staggering 44, merges into the base wall 43. However, the second top wall 48 merges at the top into 8 a second insertion strip 49, The end fits into the receiving slot 47 of an adjacent tray 40. The second insertion frame 49 keeps an oblong, second receiving slot 50 free on the underside into which the upwardly directed free end of the first receiving frame 46 of an adjacent tray 40 fits. The upper walls 45, 48 are provided above the staggered 44 with hook-in openings 53 distributed around.

The cover 60 comprises a straight top wall 61 with a rectangular main circumference. The cover 60 is viewed in the circumferential direction on two successive longitudinal sides with a lowered connection edge 62. The cover 60 comprises a first placement wall side 63 below the connection edges 62. At positions which coincide with the hook-in openings 53 the placement wall sides 62 are provided with projecting hook parts 64 which engage in the hook-in openings 53 of the tray 40. At these positions, first hollow hook sleeves 65 are formed on the placement wall sides 62. The first hollow hook bushes 65 have an internal first insertion channel 66 which is closed with a first break port 67. The cover 60 is provided in the circumferential direction two consecutive longitudinal sides with bearing edges 70 which fit on the lowered connecting edges 62 of an adjacent cover 60 such that the upper walls 61 jointly form a continuous upper surface of the insulation system 10. A slot 7 is formed on the underside of the bearing edges 70 for receiving a flexible seal 81 which is first laid in a slot over the break gates 67 in the connecting edges 62. The lid 60 comprises a second placement wall side 72 below the second connection edges 70. At positions which coincide with the hook-in openings 53, the second placement wall sides 72 are also provided with the projecting hook parts 64 which engage in the hook-in openings 53 of the tray 40. The second hollow hook sleeves 73 have an internal second plug-in channel 74 which is closed with a second break gate 75.

The insulation system 10 is mounted against the side wall 2 by fixing the mounting profiles 11 parallel to each other with the base strips 12 against the outside of the side wall 2, for example by screws screwed through the base strips 12 into plugs in the side wall 2. Subsequently, the trays 40 are fixed under the same orientation between the mounting profiles 11, the trays 40 coming into mutual relationship as shown in figure 3B.

As an illustration, Figure 3B shows that first the tray 40 of the lower insulating cassette 30a is fixed between two mounting profiles 11. The bottom wall 41 is pressed onto the two support ribs 13 and the hook edge 52 snaps behind the hook rib 16. The flexibility of the base wall 43 allows it to be pushed slightly inwards along its length to also fix the fixation edge 51 between the retaining ribs 17, 18 to stabbing. Subsequently, the trays 40 of the cassettes 30b-30d to be placed above are mounted in the same manner. Figure 3B shows that after filling of this row, the tray 40 of the first cassette 30e of the following row is mounted. Here, the second insertion bar 49 of the tray 40 to be placed engages the first insertion rail 46 of the already placed tray 40, the flexible seal 80 guaranteeing a watertight connection. This relationship is also established between the trays 40 in each row between the mounting profiles 11.

After the trays 40 have been placed, the lids 60 are snapped into the trays 40. The support edges 70 thereby lie on the lowered connection edges 62. The insulating cassettes 30a-30h all have the same spatial orientation with respect to each other, within which one supporting edge 70 is always directed downwards to cover a connecting edge 62 located below them tile-wise.

Rainwater therefore extends downwards in the vertical direction H through the different covers 60 and will nowhere end up behind the insulating cassettes 30a-30h.

When placed on the container 40, the lid 60 permanently snaps into place through the hook parts 64 which engage in the hook-in openings 53. The cover 60 can only be removed by piercing the break gates 67, 75 with a screwdriver and thereby bending the hook bushes 65, 73 inwards, so that the hook connection there is canceled.

The insulating cassettes 30a-30h each form an insulating air chamber 90. Figure 6 shows an alternative structure of the insulating cassettes 30a-30h, wherein a second layer of trays 40 is placed on the trays 40 between the mounting profiles 11 and then the lids 60. an additional insulating air chamber 91 is formed in this manner.

Figures 7A-7D also show different ways of constructing the insulation system 10 against the side wall 2. Figure 7A shows the mounting as discussed above, wherein the mounting profiles 11 are mounted directly against the side wall 2 to provide an air space 92 under the insulation cassettes 30a-30h to keep free the height of which is smaller than the height of the air chamber 90 in the insulating cassettes 30a-30h.

In Fig. 7B the mounting profiles 11 are mounted on ridges 100 against the side wall 2, whereby an air space 93 is kept free under the insulating cassettes 30a-30h, the height of which is equal to the height of the air chambers 90 in the insulating cassettes 30a-30h.

In Fig. 7C, the mounting profiles 11 are mounted on ridges 101 against the side wall 2, whereby an air space 94 is kept free under the insulating cassettes 30a-30h, the height of which is approximately twice the height of the air chambers 90 in the insulating cassettes 30a-30h. As a result, sufficient space is available for pipes 120, 121 and tubes 122 under the insulation cassettes 30a-30h.

Figure 7D schematically shows a transition cassette 30j which is suitable for bridging differences in height between the insulation cassettes 30a-30h on the 11 different ridges by means of edges adapted for this purpose.

Figure 8 shows the insulation system 10 on the flat roof 3. The mounting profiles 11 are placed on wedge-shaped ridges 102 so that the covers 60 of the insulation cassettes 30a-30h lie under a slope. In this example, the slope is 2 degrees. The insulation cassettes 30a-30h also have the same spatial orientation with respect to each other on the roof, within which a second connecting edge 70 is always directed downwards in order to cover a first connecting edge 70 in a tile-like manner. Rainwater therefore flows downwards in the vertical direction H over the different covers 60 and will not end up anywhere behind the insulating cassettes 30a-30h.

The insulation system 10 according to the invention 15 provides the thermal insulation of the building 1, wherein the air chambers 90 form a stationary layer of air around the building 1. When the building is provided with air heating or air cooling for the benefit of the indoor climate in the building, it can be improved by activating the air spaces 92-94 between the relevant wall and the insulation cassettes 30a-30h. To this end, the building is provided with an air treatment system with a blower that first transports part of the inside air of the building to be discharged through the air spaces 92-94 before it escapes the free outside air.

In the first case, when the outside temperature is higher than the intended inside temperature in the building, part of the inside air to be refreshed that has already been cooled by the air cooling is continuously passed through the air spaces 92-94 through which the respective structural wall against which the insulation system 10 is attached on either side to assume the temperature of the indoor air. In the second case, when the outside temperature is lower than the intended inside temperature in the building, a portion of the inside air to be refreshed that has already been heated by the air heating is continuously passed through the air spaces 92-94 so that the respective 12 structural wall against which Insulation system 10 is mounted on either side to assume the temperature of the indoor air. In both cases, the structural wall against which the insulation system 10 is mounted remains at the temperature of the inner space itself, as a result of which the air cooling or air heating takes place efficiently and fluctuations in the inner temperature as a result of changing outside temperatures are prevented.

An additional advantage of activating the air spaces 92-94 between the respective wall and the insulation cassettes 30a-30h is that inside the building no more air ducts are required for the removal of the indoor air to be replaced, because this fraction through the air spaces 92- 94 is being conducted.

In this example, the insulation cassettes 30-30 have all the same shape and color. It is also possible to provide all kinds of roof components and facade components, such as window frames, cable ducts, awnings, etc. with the same edge couplings as the insulation cassettes shown, so that a complete building envelope can be applied. Furthermore, it is possible to provide a corner solution whereby one integral building shell can be built over the side walls and the roof. The covers 60 can be provided with different colors, decorations or functionalities, such as solar cells or lighting. A building can get a new look by only varying in the covers 60. The mounting profiles 11 and the trays 40 can then remain seated.

The above description is included to illustrate the operation of preferred embodiments of the invention, and not to limit the scope of the invention. Starting from the above explanation, many variations will be evident to those skilled in the art that fall within the spirit and scope of the present invention.
