Sıvaterm İzoçatı High Performance Insulation Screed

It is an ecological plaster in powder group class with dry form containing boron, stone hair, glass beads and expanded minerals. It is used as the last floor in order to provide water, heat and sound insulation on the roof floors of the buildings. It can also be used on basement floors (under pavement), pitched concrete roofs. Thanks to its jointless structure, it does not form thermal bridges. It acts as a fire barrier. It reduces the load of the building as it does not require a protection screed.

- It makes high performance waterproofing.

- It also provides heat and sound insulation.

- He's breathing. It prevents the formation of mold, moisture and bacteria.

- It acts as a fire barrier.

- It does not form thermal bridges with its jointless structure.

- Since it does not require a protection screed, it does not impose an extra load on the building.

- Easy to prepare and apply.

Usage Areas

Sıvaterm İzoçatı is a material with high performance water repellency. It is used as the last floor in order to provide water, heat and sound insulation on the roof floors of the buildings. It can also be used on basement floors (under pavement), open terraces, sloping concrete roofs.

Thanks to its jointless structure, it does not form thermal bridges. It acts as a fire barrier. It reduces the load of the building as it does not require a protection screed.

Preparation of the Product

7 liters of water is poured into the vessel where the mortar will be prepared and the 12 kilogram Sıvaterm bag is completely emptied. Since Sıvaterm Plaster has a composite structure, the dry mixture is not homogeneous. For this reason, the bag should never be divided, it should be completely emptied into the boat at once. Multiple bags can be discharged into a boat.

Then it is mixed with a mixer with 500-600 rpm. (High speed mixers may damage the mortar.) After a waiting period of 10 minutes, 0.5 liters – 1 liter more water is added according to the consistency of the mortar and mixed for 1-2 minutes until it reaches the appropriate consistency. The material, which is ready for application, can stay in the boat for a maximum of 3 hours.

Application Method

The application of Sıvaterm İzoçatı High Performance Insulation Screed can be done with the help of a steel trowel or with a suitable screed machine. Drying time (15 °C temperature, 50% humidity environment) is 36 hours. It can be applied at atmospheric temperatures between +5 °C and +45 °C.
