Thermal Insulation is the exterior cladding work, which is created to warm up more in winter and cool down more in summer, and to places such as the exterior and walls of buildings, window edges, jambs and doors . The Importance of Exterior Sheathing Application is as follows ;
What is the Importance of Thermal Insulation?, What are the Benefits of Thermal Insulation?
- Thermal insulation reduces gas, soot and dust emissions and prevents environmental pollution.
- With the help of thermal insulation, you will have a more healthy and comfortable life.
- By preventing the formation of damp areas and mold, microbes are prevented from living in the place where the insulation is made.
- Thermal Insulation ; With the help of an ideal sheathing in accordance with the regulations, it allows to stay cool in the summer and warm up better in the winter by saving an average of 50% from the expenditures we make for heating or cooling.
- With the help of exterior cladding , there will be stable room temperatures in the place where insulation is made. In this way, the place becomes more comfortable and healthy. Places close to the window, such as in places where there is no insulation, are not cold, and the interiors are not warmer. Thus , you save the energy you use for heating and a heat balance is created in your home or room.
- It prevents mold, deterioration and black spots on walls and ceilings due to temperature differences.
Thermal insulation in buildings is a smart, practical and easy solution that aims to prevent heat loss. Where is the building sheathing done? some of the most ongoing areas to be insulated should include ceilings, cavity walls, exterior walls and floors. Since Eps Styrofoam thermal insulation boards can be cut easily, it offers the opportunity to make flexible designs for exterior cladding models .
Heat Insulation (Sheathing) Usage Areas ;
- Roof area of buildings and building walls,
- In buildings and houses on the ground floor in contact with the ground,
- In the parts that separate the floors or stay between the floors,
- In installation pipes, installation system and ventilation gaps and channels,
- It can be applied to the parts and walls facing the unheated parts such as garage, warehouse, cellar.
Exterior Sheathing and Its Benefits
Today, the concept of energy performance in buildings has gained more importance than ever due to increasing energy costs and regional constraints . Along with this concept, the need to limit energy losses and gains in buildings has emerged and applications aiming at energy conservation and sustainability have spread and developed in the construction market.
Most of the heat losses in buildings occur on the exterior surfaces. For this purpose , it is of great importance to insulate the building from the outside as well as from the inside and to protect it against energy losses .
The energy efficiency achieved throughout the building increases the quality of the building while reducing the operating costs throughout the life of the building, and at the same time offers a comfortable living space to the building occupants . For this reason , increasing the level of isolation makes our living spaces more energy efficient, sustainable and functional.
Exterior cladding materials surround the exterior walls of the building, preventing the formation of thermal bridges and playing a major role in preventing energy losses. The opportunity to create the buildings in the most heat efficient way in terms of cost advantage arises at the design and construction stage.
Jamb cladding results in five major factors of exterior wall materials
Now the high-rise buildings under construction will be installed outside the wall insulation board , which can play the role of thermal insulation and have a protective effect of the outer wall, can increase the outer wall of the brick concrete life. But with the use of time to expand the outer wall, the thermal insulation material will appear aging phenomenon, then cause aging? The following small series of simple entries is divided into about five areas:
1, Thermal stress changes the amount of unstructured structure in thermal expansion and contraction caused by the temperature difference, so that it is always in an unstable state.
Therefore, thermal stress is one of the main destructive forces of the outer insulation layer of an exterior wall with a high-rise building. Compared with the multi-storey or cottage building, the taller building is exposed to more sunlight than the outer layer, the thermal stress is greater, and the deformation is greater. Therefore, when designing the insulation structure, the choice of thermal insulation material should meet the flexible shielding principle, and the deformation capacity of the material should be greater than the deformation capacity of the inner layer material.
2, air pressure. In general, there is a large pressure loss, negative air pressure suction, positive pressure caused by a high-rise building insulation layer, so the outer insulation layer must be significantly resistant to air pressure and air pressure, according to the requirements of the space. Without the insulation layer , it eliminates the air layer to prevent air pressure, volume expansion due to the loss of the insulation layer , especially in the negative pressure state of the air layer insulation layer.
3, earthquake force Earthquake force, high-rise building structure and extrusion, shear or deformation insulation layer, and the more insulation layer, the greater the magnitude of the earthquake, the more severe. For this, external thermal insulation with high adhesion content is to absorb dispersion and earthquake stress, under the premise of meeting the flexible gradient principle, reduce the load on the surface of the insulation layer to prevent impact. It requires a large field of seismic force under insulation to break, split or fall.
4, water or water vapor high-rise buildings should use good hydrophobic, good vapor vapor permeability of the external thermal insulation material, to avoid water or water vapor damage, avoid water or water vapor in the transfer process. With increasing moisture content, wall condensation or insulation layer is formed, the high-rise building insulation layer is increased to improve rain erosion and anti-freeze melting capacity.
5, Fire multi-storey buildings require higher fire ratings than multi-storey buildings. The insulation of the high-rise building must have superior resistance to fire and prevent the spread of fire and the release of sugar or poisonous gases, the volume can not be too low, can not be reduced, otherwise the damage to the house or firefighters Rescue operations caused great difficulties.
Benefits and Advantages of Exterior Heat Insulation Application
The benefits of the exterior sheathing system in terms of performance;
1. Thermal Comfort
With the help of thermal insulation, a homogeneous temperature is provided at every point of the living space, reducing the heating and cooling requirements. Thus, both comfortable and healthy living spaces are created .
2. Reducing Heat Loss and Gains
Excessive heat leaks or gains may occur from the facades of buildings without exterior sheathing , and if this problem is not eliminated, it will cause a large amount of energy use and indirect costs. The exterior sheathing system creates an airtight barrier around the exterior of the structure, creating an air-tight barrier that causes air loss/gain, all gaps, capillary cracks, etc. seal parts.
3. Condensation Prevention
Interlayer condensation is the condensation on the surface of the layer as a result of the hot and humid air detected in the building infiltrating the structural sections and encountering a cold surface and the decrease in the water vapor carrying capacity within it.
Applying an exterior cladding system to the structure prevents the formation of condensation between the layers, because the dew point temperature shifts towards the exterior of the insulated building and the risk of condensation on the interior layers is eliminated. The use of a vapor-permeable insulation material allows the permeability of water vapor and allows the building to breathe, further reducing the risk of condensation.
4. Elimination of Thermal Bridges
Since the exterior insulation system creates a dense layer around the exterior of the building to which it is applied, thermal bridges are greatly reduced in owned buildings and almost completely eliminated in new buildings. For this reason, covering the existing thermal bridges (eg outer beam and column junctions) with insulation prevents significant heat losses and prevents the risk of condensation.
5. Prevention of Moisture Formation on Walls
A large area of moisture in existing exterior walls is caused by moisture penetration, moisture increase or condensation (especially surface condensation). This situation causes mold or fungus formation on the facade walls. Establishing the thermal balance with the exterior thermal insulation system to be made on the exterior walls of the building and renovation works on the building components (for example, renewal of missing or damaged plaster, scraping and reapplication of bad mortars, etc.) provides long-term protection on the building facade.
6. Fire Protection Performance
Exterior insulation system applications created with Eps Styrofoam materials meet the structural fire protection requirements at the highest level. Systems in which rock wool insulation board is used are in the B1 category, which is the highest inflammability category according to EUROCLASS - European Harmonized Classification System- norms.

7. Noise Prevention
Exterior thermal insulation systems significantly increase the quality of life inside the buildingair -generated noise to a certain degree, according to their structures. Typically, foam is formed or cut into blocks, which is the best fit among siding ideas . Foam insulation boards are flammable and must be coated in a non-combustible chemical called Hexabromocyclododecane (HBCD). You can reach our article on exterior sheathing types from the link.
