A roof waterproofing as a flat roof renovation with simultaneous flat roof insulation, we carry out without great effort with PUR Ortschaum roof spray foam directly on the existing substrate.

This industrial roof waterproofing with simultaneous roof insulation is a high-performance insulation material that has been used successfully for decades for flat roof insulation and flat roof waterproofing in industrial roofs and also for private customers.

The flat roof insulation Flat roof renovation Flat roof waterproofing with PUR Ortschaum roof foam over our mobile, heated Ortschaumanlagen offers the most effective and safest way to permanently seal and insulate a flat roof in one operation, without annoying construction site.

The PUR Ortschaum can be applied directly to the previously cleaned by us roof, so no demolition of the existing substance is required, which in turn saves costs and guarantees safety in short-term weather changes, since the roof does not need to be opened. In commercial buildings, a loss of production below the work surface is thereby avoided.

PUR Roof Spray Foam is applied in one operation over the entire surface and applied without joints even in critical areas such as connections to components, skylights, penetrations, etc., sprayed on. Even the most difficult geometries and roof shapes can be permanently and safely sealed and insulated with PUR Ortschaum.

PUR Ortschaum has excellent insulation values ​​and at the same time reliably seals, with very high diffusibility (breathable).

Rising components and penetrations such as fans, skylights, chimneys, antennas, etc. are seamlessly and seamlessly integrated into the finished surface.

Thus, no cold bridges can arise in this system

Also, the water inlets of the roof drainage of gullies and drains are also integrated safely and homogeneously.

After a short reaction time (4-5 seconds), the PUR Ortschaum receives its volume, in which it "rises like a yeast cake". During the reaction time, the PUR Ortschaum passes through a very sticky phase in which it is safe and full surface with the substrate combines. An underflow of water is no longer possible.

After about 30 seconds, the material is cured and walkable.

Short processing time of the flat roof insulation with PUR-Ortschaum

Since the PUR Ortschaum can be applied on more than 1000 m² per day in one shift, long processing times are not required.

The PUR Ortschaum can be applied in several layers, depending on the requirements of the insulation value, thus the requirements of the current Energy Saving Ordinance (EnEv) can be achieved cost-effectively.

Finally, the polyurethane roof foam is provided with a UV protection to protect it from sunlight.

For this we use our liquid plastic PUREelastik,
