About Heat Insulation
What is thermal insulation? Should I do it? Who should I have? Which products should I choose? Are the materials used harmful to health? It is very confusing to take a decision by finding answers to dozens of questions like these.
Glossary of thermal insulation means “the fact that heat is not transmitted from high temperature zones to low temperature zones”. It is also popularly known as jacketing. Although thermal insulation has been built only recently to obtain energy identity certificate, it is actually our need for more important issues. We must implement the thermal insulation sheathing application in our buildings both individually and socially. Why do we say both individually and socially? In order to answer this question, why should we get thermal insulation?
Why should we have thermal insulation in our buildings?
- For Personal Comfort: The fuel saving provided by the external thermal insulation applied, sheathing cost can be covered within 3 years on average. This depreciation period may vary between 2 and 5 years depending on the amount, type and type of fuel consumed. Considering that Heat Insulation is an economy that will last for 4 seasons, the depreciation period will be shortened if the air conditioning expenses (electricity, cooling gas, service) which will be reduced with insulation in the summer season are taken into account.
- For Health and Comfort: In thermally insulated houses with external sheathing, the heat is evenly distributed. As the temperature of the walls increases, there is no condensation and no air flow and healthy and comfortable living spaces are obtained. With Thermal Insulation, you can have a healthy living and working area with your loved ones.
- For Aesthetics: The surface of your old, worn and pale buildings is renewed with the thermal insulation jacketing system.
- For Safety: On the walls of the building which is not thermal insulation sheathing, the reinforcements in the concrete become corroded and lose strength due to condensation over time! With sheathing, you can prevent your facades from being worn out against external factors and ensure that your building remains structurally longer.
- For the Environment: When you have exterior sheathing, you use less fuel. You contribute to the prevention of global warming due to air pollution and the protection of the environment.
- For the Country Economy: It is possible to reduce our energy costs by 50% each year by half by providing 50% energy saving with a proper sheathing technique.
Thermal Insulation Boards
As stated in the above definition, heat insulation is essential to prevent the transfer of heat from one area to another area. In order to achieve this, there must be a barrier in between. Here in winter, outside the cold air outside our house should be prevented from entering. In summer, the outside of the hot air inside to prevent the air from getting inside, but the cool air inside should be prevented from coming out. How is this achieved? It is not possible to prevent the passage of air from one place to another with a paint or a plaster. We can block this barrier again with the air itself. If we place the air in a plate, just like in thermally insulated double-glazed windows, we can create a barrier. We call these barriers thermal insulation boards and they are sold in the market as stone wool or EPS boards.
It is not possible to make efficient thermal insulation in buildings with external plaster or paint-like materials in today’s technology. The outer facades can be covered with heat resistant paints. However, these paints are characterized by the protection of the underlying surface based on the temperature at the time of exiting the atmosphere. It is located in the layers under the paint of materials that do not pass the heat outside. Maybe sunlight can be reflected by using the reflective feature with paint, but it is also not possible to prevent the outside heat from entering or vice versa. Likewise, in products sold under the name of thermal insulation plaster, efficient thermal insulation can be achieved only by applying the plaster over certain thicknesses, but due to the characteristic properties of the plasters, it is not possible to apply the plaster at high thicknesses and remain in the façade. For these reasons, the correct heat insulation in the right buildings can only be achieved with the boards. This sheet can sometimes be stone wool and sometimes it can be EPS sheets.
Questions about Thermal Insulation
There are some question marks in the heads about the products used in thermal insulation applications in buildings. First of all, whether EPS sheets used are carcinogenic or not. While reading this article, people who smoke or hold cigarettes in their hands do not need to consider whether such a risky situation exists in EPS plates. Because the cigarettes in the packaging of cigarettes “kills” even though the phrase is used with pleasure without worrying about any harm to the body as long as you do not eat such a concern is unwarranted. The important issue is to examine the technical data sheets of the brand to be preferred.
Another question mark is whether the sheets are flammable. EPS sheets are non-flammable. They are classified as Class B1 fire. In this regard, the technical sheets of the products must be checked. What does the non-flame class mean? When you light the lighter in the middle of the EPS plate, the flame will shrink, but when you turn off the lighter, the flame in the plate will extinguish and will not splash into other areas. This shows that the flame does not go to the other corners of the plate by foot, which is called the non-flame class.
There are also dowels used in jacketing. These dowels are thought to crash all over the building and weaken the building. Dowels are of different lengths depending on the thickness of the plate used. They do not extend to the main bearing pillars and beams on the exterior of the building, which means that you can hang any shelf or table in your house as if you were doweling on the wall. You can read our article nasıl How should the dowel application be applied in jacketing? Dü about the length of the dowels to be used.
