Advantages of External Thermal Insulation

• Preventing heat losses, resulting from external wall, it provides approximately 50% saving from heating and cooling costs.

• It is the ideal method for building physics as building walls are wrapped completely. It prevents thermal bridges that shall occur over ferroconcrete building elements (column, beam etc.).

• Thermal stress, resulting from heat difference in wall construction, is minimized. Wall is protected from effects of external environment totally.

• Condensation risk is minimized.

• As there shall not be any reduction in internal volume, net floor area is not affected.

• It prevents corrosion that may occur in reinforcements of building carrier system.

• It decreases external and internal wall maintenance costs of buildings, it increases the life expectancy of the building.

• It avoids humidity and growth of mould or bacteria in the building.

• According to European Union Standards, thermal comfort is defined as the difference between indoor temperature and inner wall surface temperature is maximum 2-3 °C. External Thermal Insulation system provides balanced heat distribution and establishes healthy and comfortable life conditions.

• As it decreases fuel consumption, it diminishes environmental pollution.

• Installation in new buildings ensures that initial investment cost is decreased.

• It provides new and aesthetic appearance to old buildings.


Instructions for Application

Firstly surfaces, where application shall be made for the first time, have to be smoothed with rough cast. All surfaces are removed from swollen plaster and paint residues, dust, dirt and oil.

Building’s sub-basement level, where thermal insulation plates shall begin, is marked around the building with the aid of water gauge.

Then sub-basement profiles, selected according to thicknesses of insulation plates, are fixed on wall by leaving 0.5-1 cm expansion joints.

25 kg Adhesive Mortar is added to 6.25 kg water slowly and is mixed with a mixer (400-600 rpm) for 3-5 minutes until achieving a homogeneous and smooth mixture. Approximately 3-5 minutes later, it is mixed for 30 seconds again. No material other than mixing water shall not be added to the mixture. Application shall be made at times, where sunlight is not direct or without wind in hot weather.

Prepared mixture is applied to plate surface according to grading condition of building surface along the edges of the plate with steel trowel and in the middle parts of plates, it is applied in blocks. In very smooth surfaces, adhesive mortar can be applied to thermal insulation plate with toothed trowel. Consumption is 5 kg/m2 on average.

Insulation plates are stuck onto wall surface by placing on sub-basement profiles horizontally. Subsequent lines are stuck in its scale and diversed. Minimum 24 hours after sealing, by using wall plugs, plates are mechanically fixed onto surface.

The number of wall plugs is 6/m2. It is adjusted as one on each plate edge and two on the middle of plates. Edge wall plugs are especially matched to the junctures of plates. Especially in high multi-storey buildings, the number of wall plugs is increased in corners of building and two wall plugs are applied for each plate in corners.

Corner Profiles are placed to ensure impact resistance of corner points.

Plaster mortar is added to 4.60 kg water slowly and is mixed with a mixer (400-600 rpm) for 3-5 minutes until achieving a homogeneous and smooth mixture. Approximately 3-5 minutes later, it is mixed for 30 seconds again. Plaster mortar is applied one layer with steel trowel. To achieve a homogenous thickness, plaster is smoothed on plate with a 3x3 mm square-toothed trowel. Plaster is fixed by pressing on lightly. 10 cm lapping is made in joint parts of net towards its width and length.

After putting plaster water up to a level, where the net shall not sink, the application is completed by applying 2nd layer of plaster. In application of two layers of plaster, total consumption is 5 kg/m2.

Application is completed by applying final layer. As second layer of plaster is plugged, desired appearance is achieved by applying one of the alternatives of decorative coating or paint, which shall be the last phase.
