• Why is thermal insulation necessary?

      Thermal insulation reduces heat loss from the building to the outside, saves energy, It does not require extra power and cost for the protection of thermal insulation, it is permanent and does not require maintenance, It contributes to the reduction of heating costs in winter and cooling costs in summer, It provides homogeneous distribution of heat in buildings, Prevents humidity inside the building, creates a healthy and comfortable environment, Prevents mold, black spots, plaster or paint blistering on interior surfaces as a result of sweating, Prevents damage that may occur in buildings as a result of heat movements and steam condensation, Provides permanent beauty on exteriors, Reduces carbon dioxide emissions into the atmosphere. contributes to the reduction of air pollution and protection of the environment by reducing
    • Why should thermal insulation be made on the exterior?

      Because thermal bridges that may occur in areas such as columns, beams and curtain walls cause heat loss in buildings and these thermal bridges can only be completely covered with external thermal insulation. Thanks to the thermal insulation applied on the exterior, heat loss is prevented for all thermal bridges. In addition, thanks to the exterior thermal insulation, the exterior of the building is not exposed to adverse weather conditions such as overheating, extreme cooling, precipitation and frost, and water absorption from the façade is balanced. Thus, deformation (cracking, swelling, etc.) does not occur for many years. Gas concrete, pumice block, brick, etc. in the building. Is it necessary to apply thermal insulation when materials are used? According to ISO and CEN standards, materials with a thermal conductivity coefficient (λ) lower than 0.65 W/(m.K) are defined as thermal insulation materials. Materials with a thermal conductivity coefficient (λ) above 0.065 W/(m.K) are called "building materials" (their thermal insulation property increases as the thermal conductivity value decreases, and decreases as it rises). It is not a thermal insulation material for building materials, but it is a building material that can contribute to thermal insulation materials.
    • Does thermal insulation contribute to sound insulation?

      Thermal insulation contributes to sound insulation. Thermal insulation applications made with mineral-based thermal insulation boards (rock wool, glass wool, etc.) contribute more to sound insulation.
    • Can thermal insulation be made with paint?

      Thermal insulation performance is directly proportional to the insulation value and thickness of the thermal insulation material. In other words, the greater the thickness of the thermal insulation material, the higher the performance. Since the application thickness of exterior paints is very thin, they cannot provide the desired thermal insulation performance.
    • What is an energy performance certificate?

      The energy identity document is the official document containing information about the building's energy need and energy consumption classification, insulation properties and efficiency of heating/cooling systems. In the energy identity document, information about the energy need of the building, insulation properties, efficiency of heating/cooling systems and the energy consumption classification of the building are kept as a minimum. It must be taken in accordance with the "Energy Efficiency Law No. 5627" and the "Energy Performance Regulation in Buildings" issued accordingly.
    • Who issues the energy performance certificate?

      The energy identity certificate is issued by energy efficiency consultancy companies, and for new buildings at the project stage, by freelance engineering and consultancy companies.
    • Is it obligatory to get an energy identity certificate?

      The "Energy Performance Regulation in Buildings" published in the Official Gazette dated 5 December 2008 and numbered 27050 obliges new or existing buildings to obtain an energy identity certificate. It is necessary to obtain an Energy Identity Certificate for existing buildings by January 2020 at the latest, and the document obtained is valid for 10 years from the date of issue. If the building is to be rented or sold, these transactions cannot be made from 2020 without an energy identity document.
    • Is a low thermal conductivity coefficient of a building material sufficient for thermal insulation?

      The low coefficient of thermal conductivity of a material is not a sufficient element to express "heat insulation" on its own. The Thermal Insulation Material must have a low thermal conductivity value as well as have sufficient thickness. Here, at the point where the thermal conductivity and thickness values ​​meet, the term Thermal Resistance (R) appears as the value that expresses the "heat insulation". Thermal Resistance, R (m² K/W) value (hence thermal conductivity+thickness value) is used in thermal insulation calculations. Thermal Insulation= R= Thermal Resistance=Thickness d(m)/ Thermal Conductivity Coefficient (W/(m.K) = d/λ
    • Do the materials used in insulation prevent the building from breathing and cause it to rot?

      With the sheathing made with thermal insulation materials, it is ensured that the bearing elements of the building are protected from the wearing effects of external weather conditions and that they are protected from stresses that may arise from extreme temperature differences. Hot in the summer and cold in the winter, the outside air creates stresses due to expansion and contraction in the building elements that are not protected by sheathing. These stresses cause the appearance of capillary cracks in the structural elements over time. With the exterior sheathing, it is ensured that the water that can seep into these capillary cracks from the outside does not both freeze and cause larger cracks, and that it does not reach the iron reinforcement and cause corrosion.
    • Is the thermal insulation applied only on the outer walls sufficient?

      In a building, heat insulation should be applied to the floor and roof along with all the facades. Contrary to popular belief, heat losses or gains are caused not only by the façade but also by the heat transmitted from the roof and floor. Since the floor of the building is a reinforced concrete element, the floor acts as a thermal bridge and quickly transmits the heat drawn from the building columns to the ground, causing heat loss. On the other hand, since the heated air inside the building rises physically higher, to the attic, heat losses from the roof are also higher. Instead of laying flat slabs between floors, building elements that will provide insulation should be used, and heat insulation should be made from the floor or rafter level of the attic floors. In addition, the windows must be correctly selected as joinery and double glazing according to the climate zone.
    • Does the increase in the hardness of thermal insulation materials increase the success of the insulation?

      It is not correct to say that the thermal insulation value of the hard (dense) material is better, the evaluation should be made by considering the physical measurement values ​​of the material and the place of use. For example, the material to be used under the screed can be chosen with a high density, and its thickness can be prevented from decreasing over time. If it is used in sheathing, it is more difficult to adapt to the thermal stresses of the plaster on the hard heat insulation material in summer and winter due to its hardness, and this situation increases the risk of plaster cracks. It should also be taken into account that the rigid thermal insulation material has greater resistance to water vapor transmission.
    • Is thermal insulation an expensive expense?

      Insulation is not an expense, but an investment that contributes to health, comfort and environmental cleanliness. The cost of thermal insulation is between 3% and 5% of the building construction cost. It should not be forgotten that it should be perceived as an investment that pays for itself by reducing the heating and cooling costs by at least half, and then provides savings and comfort by making the consumer spend less for a lifetime.
    • What are the advantages and disadvantages of polyurethane coatings compared to epoxy coatings?

      Polyurethane coatings are recommended for applications where high adherence, elasticity, resistance to outdoor conditions and UV, resistance to sea water and salt, waterproofing and scratch resistance are required. Epoxy coatings, on the other hand, are preferred in applications where factors such as hygiene, chemical and mechanical durability, and high adhesion strength are important. Epoxy materials do not have UV resistance. Both systems have advantages and disadvantages compared to each other, and in order to find the right solution, expectations from materials must be set very well.
    • How should concrete surface preparation be done before epoxy coating is applied?

      The surfaces on which epoxy coating materials will be applied should be free of weakly adhered parts, cleaned from dust, oil, tar, pitch, paint, silicone, curing material, detergent and mold oils, and dry. If the concrete is damp, wait until the surface reaches the dryness to be applied with epoxy. The application floor should have cured for at least 28 days and the moisture content on the surface should be at most 4%. The surface of the concrete to be coated with epoxy must have a roughness to ensure adhesion. Epoxy coating should not be applied to very glossy concrete surfaces. If the concrete surface is finished brightly, these surfaces should be roughened by milling, balling or grinding. The removed layers should be removed from the surface and the main concrete should be found. If there are cracks and cavities on the concrete floor, they should be repaired with epoxy-based repair mortars.
    • How long is the life of epoxy floor coatings and how is it repaired?

      Epoxy based coatings, preferably interior; Extremely long-lasting, which is more resistant to chemicals and mechanical wear compared to alternative flooring materials used in spaces; coating materials. Dense pedestrian and vehicle Even if the mechanical impacts that may occur on the surface as a result of traffic cause some scratches and deformations, it is possible to repair the coating. Surface renovation can be done at very low costs. The contamination that may occur on the surface of the coating over time does not penetrate into the coating and can be easily cleaned with suitable cleaners. A trial should be made regarding the chemicals considered to be used for cleaning and the manufacturer and applicator should be consulted for the selection of the appropriate material. In order for the colors of the epoxy coatings not to fade for a long time, the coatings should not be left under direct sunlight or strong lighting. It is possible to repair damages in epoxy-based coatings. This repair is based on the principle of removing the damaged parts from the surface and replacing them with re-coating. One of the most important issues to be considered during the repair is the difference in tone between the existing coating and the new coating. This tone difference results from both discoloration or dulling due to contamination on the surface of the existing coating as a result of use, and the difficulty of keeping the old coating tone while manufacturing the new coating color. Repair must be done by an expert team.
    • How long is the waiting time between coats in multi-coat epoxy coatings?

      Starting from the first coat of epoxy application on the concrete surface, the second coat of epoxy should be applied at 20°C without exceeding the specified times for each product. During this period, since the chemical hardening of the first layer is not fully completed, a chemical bonding occurs between the later coating and the previous one. Thus, although the coating is few; Even if it is made in layers or more, a single layer will occur. If 48 hours pass between the first and next coats, since there will be no chemical bonding, the previous layer should be roughened with sandpaper with great care, and then epoxy coat should be applied. Here, there will be no chemical bonding, but physical bonding.
