Thermal facades Thermal insulation external and internal

• Maintain the internal surface temperature at high levels thus preventing the creation of moisture or mold on the walls or the ceilings.
• Prevent the creation of steam on the structural elements of the building by allowing the water vapor to escape through the material. This is achieved through the use of polystyrene foam or mineral wool, materials with a very good water vapor diffusion.
• Minimize the effect the outside temperature has on the interior, resulting in significant energy savings for both heating and cooling.
• Cover the load-bearing structure (pillars, beams) and eliminate the thermal bridges (thermal transfer through the concrete from the outer to the inner space) that could adversely affect the internal temperature of the building from the outside weather conditions.
• Protect the pillars and beams of the building from extreme temperature changes in the in surroundings thus avoiding the thermal burdening of the skeleton of the building. Simultaneously, they eliminate the erosion and the carbonation of concrete through the effects of CO2, thus protecting the whole building and increasing its lifespan.
• Save more than 25% of energy unlike ordinary insulation, by preventing the formation of thermal bridges between walls and concrete (pillars, beams).
• Particularly effective in the restoration of buildings as except for the insulation, they protect existing structural elements (pillars -beams) and preserve the original architecture of listed buildings .
• Prevent damages to water pipes and construction material caused by moisture and frost.
• Not affected by sudden temperature changes in the environment.
• Help architects in shaping the facades as they allow the construction of various levels, shadings, frames etc.

Construction Method

1. The surface on which the insulation material will be placed should be clean and smooth. Any dents on the exterior surfaces of the building should be covered with the appropriate materials.
2. The polystyrene plates are placed crosswise for better welding. The insulating polystyrene plates, as they are of low weight (6-10 kg / m2), are glued onto the face of the building. For better support we can use 4-6 plugs per m2 (depending on the total surface and the height of the building).
3. In the intermediate layer strengthening plaster is placed, that can be fitted either by spray machines or by special trowels. Spray machines give better results as they quicker in operation and the materials do not have time to dry.
4. The final layer consists of ready-made pastes (organic coatings) which can be fitted by a spray machine or special trowels. Furthermore, in this case (the final coating) we can use silicone self-cleaning plaster.
5. A special technique is required while fitting polystyrene on waterdrippers, expansion joints and the shutters of window frames.
