Ceramic thermal insulation panels - » F-r-

A distinction is made between flat roofs and roof terraces over inhabited rooms:

1.) between the conventional flat roof, in which the thermal insulation layer is applied from below against water vapor diffusion, and is protected from the ingress of moisture by means of welding strips or foils from above,

2.) and the inverted roof, where the moisture seal is directly on the concrete ceiling or similar. About that the heat protection measure is dimensioned larger than with a conventional flat roof, with closed cells Rigid foam panels (e.g. polystyrene) are made. With this system, water penetrates into the between and below the cavities in the insulation material. Dos is that Reason for choosing thicker layers for the inverted roof than for the conventional flat roof.

In both systems, a protective layer must be used to cover the moisture barrier and the thermal insulation on top.

This happens in the areas not intended for inspection this mostly through a layer of gravel. With conventional flat roofs, this serves exclusively to protect against UV radiation, the associated heating and against mechanical damage.

With the inverted roof, the gravel layer also takes on another function, that of the load!

Since the insulation panels are usually laid loosely and can be surrounded by water, there is also the risk of being blown open by wind, also the possibility of so-called "floating".

Walter Gutjahr jun. - -9- -: · .-. · ■ ·. ". ■ '. ..:.

Due to their low weight with a large water displacement the buoyancy can be so high that the insulation panels leave their intended position.

This is prevented with a so-called "load" tailored to the thickness of the insulation material. For example, a Insulation material with a thickness of 100 - 120 mm has a load of approx. 160 kp.

Further stricter regulations require even thicker insulation layers in the future, so that the minimum loads are further increased. For structural reasons alone, the demand for inverted roofs will therefore decrease.

In addition to being easy to manufacture, the inverted roof also offers unmistakable advantages in terms of moisture sealing.

Much rarer than with conventional flat roofs Leakage registered on the roof membrane. This is because the thick insulation layer is extremely resistant to mechanical damage protects and the roof skin is only exposed to minimal temperature fluctuations.

This reduces the aging of the roof waterproofing and significantly extends its life expectancy.

In the past, the coverings of accessible roof terraces were made of conventional flat roofs - tiles in a mortar bed, and made of concrete blocks on pedestals or chippings.

In the case of inverted roofs, concrete slabs were used almost exclusively, as laid before, used.

Their disadvantages, such as surfaces that require intensive cleaning and their not necessarily decorative appearance, are well known. However, their high weight is required as a load in the methods practiced up to now.

Ceramic tiles have so far not been used, or only rarely, on inverted roofs.

Although the practical advantages and the diverse design options, that a ceramic tile flooring offers are generally recognized.

The aim of my considerations was:

1.) To develop an element in which the top covering (accessible) and the insulation material are combined and prefabricated in one can be.

2.) To develop a processing method in which the high total weight by previously prescribed minimum loads, can be reduced to a minimum.

3.) To strive for a rationalization advantage, in which the complete element is laid by only one craftsman where previously the roofer created the thermal insulation and the tiler created the tiling.

Ceramic insulation panels

consist of a combination of frost and moisture resistant Materials. Their size is variable and is based on the size of the tile. It turns out to be practical and handy Formats from 50/50 cm - 120/60 cm but also larger.

Ceramic stoneware tiles according to DIN 18155 and split tiles according to DIiN 18166 are preferably used as the covering surface (Figure 1.1) and other, not mentioned, but frost-resistant tiles and slabs.

These are required with the insulation boards (Figure 1.3) The starch is put together by means of a hydraulically setting thin-bed or medium-bed mortar (Figure 1.2) or reactive resins. That Insulating material must consist of closed-cell rigid foam (e.g. polystyrene) and have a serrated milling on the top (Figure 1.9). There are two advantages to this

1.) the profiling ensures better ο / η Q η π r mechanical clawing of the contact layer (2) with the insulating material (3),

2.) the total cross-section of the contact layer (2) is increased and the compressive strength is improved of the top covering.

After applying the contact layer (Figure 1.2), the tiles inserted. This layer is compacted with a vibration device and creates an intimate connection with the insulating material (3).

The underside of the insulation panels also has a serrated profile (Figure 1.9) or a so-called dovetail profile (Figure 1.10).

With the dovetail profile, which is milled, one obtains not only the adhesive but also a greatly improved mechanical one Adhesion to the laying and leveling mortar (Figures 1 + 2-4).

Another possibility is a good connection with the laying mortar to achieve is that the sawn or milled underside of the insulating material (3) with an injectable thin-bed mortar that is applied under high pressure.

The tiles of each element are jointed with one another using hydraulically setting joint mortars or reactive resins.

Below the contact layer (FIG. 1.2) there is one on two sides each insulation board a soft, rot-proof foam strip (Figure 2.12) glued on. He is supposed to be during the grouting work prevent grout or elastic joint sealants from sinking into the underlying cavities.

Due to the different thermal expansion of the top covering material and the rigid foam, there is a gap between the joints necessary.

Ceramic thermal insulation panels should be on a, already in The sealing must be laid with a slope to the floor drains, as prescribed for all other flat roofs is.

The elements, which are flat in their surface, are each laid on a pre-drawn mortar rim (Figure 3.4) and pounded in, as can be seen in Figure 3. It is important that this (4) has a cavity (Figure 3.13) below the insulation panels encloses in such a way that no rainwater can flow in and out. An underflow of the thermal insulation would increase lead to a cooling of the roof cladding.

The mortar rims serve as a support and leveling layer.

With the embedding of a non-rusting structural steel mesh (Figure 1, 2 + 3-5) or a glass fiber fabric in the leveling layer creates a solid bond between the mortar rings (4) manufactured.

Since an intimate bond is created between the profiled underside of the ceramic thermal insulation panels and the mortar rings, it can be ruled out that there is a lift-off due to wind or a reddish swim due to water.

As with all walk-on outdoor coverings, their surfaces should have a sufficient slope to the respective drainage systems, This ensures that rainwater can drain away quickly. Even so, small amounts will get through the joints of the ceramic Insulation boards can penetrate. At first it slowly seeps into the laying mortar (also into the cavities) (13) and can then slowly rise above within the pores of the mortar structure the moisture seal lying on the slope seeping into the floor drains.

Since only a very small volume of water is to be expected in this level, there can be no cooling of the Roof cladding come. Rather, those act among the elements

the air chambers located (without any connection to one another) to provide additional heat protection.

Ceramic _ thermal insulation boards

can also be used for the so-called Pius roof. The basis is an existing flat roof with inadequate thermal insulation, but the roof skin intact.

An effective insulation measure can subsequently be implemented cost-effectively realize without overloading the existing ceiling with its static conditions.

It can also be used in the manufacture of a so-called duo roof.

Ceramic insulation plates

are characterized by the fact that they provide a thermal protection measure and the production of e.g. a ceramic covering can be carried out in one operation. Another benefit is the lower total weight, compared to the inverted roofs produced so far with their high load.
