Thermal insulation and sound insulation is a process aimed at improving energy efficiency by reducing heat and acoustic characteristics in the house. But when it comes to insulation materials, there are indeed many types. Rock wool insulation is also one of them, but is it a good choice for you? According to reports from source information, most houses use more than 40% of total energy for cooling and heating. But this situation is increasing every day. That's why this requires designing a better insulation layer inside the house. This way people can save some energy and electricity bills. But do you know what rock wool insulation material is and how to install it on your internal walls? In this article we will explain everything about it. In addition, it also includes some reasons why you should use it and the differences between rock wool and glass fiber insulation materials.
What is rock wool insulation, rock wool insulation material is also known as mineral fiber insulation material, adopting batt design. This is similar to glass fiber insulation material, but the material and manufacturing standards are different. Because it is not made of glass fiber, but rock wool insulation material is made of basalt and recycled slag. I know this seems impossible, but it is. Natural stone is heated in an industrial furnace at a temperature of about 1600°C, melting the rock into liquid. Then the liquid rock (also known as magma) will be exposed from high-pressure air. And the cooling of the next process is very important. So in the subsequent process, the liquid rock will enter the ultra-high-speed rotating interior. So it can turn the rock into fibrous form. At this time, all the mineral wool is ready.
And how to install rock wool insulation material in the house? Installing rock wool insulation material is similar to glass fiber insulation material. But there are some differences, because rock wool batt insulation material is harder than glass fiber texture, and the specific installation steps are as follows.
1. Collect all tools and measure wall area
Before starting, all you need is to collect these tools I listed below in one place. Therefore, when you need an emergency, you don't need to leave this place to use. Dust mask, protective glasses and gloves, tape measure, utility knife, saw, ruler etc. When you collect these tools, the other part is used to measure the wall area. Because many people do not install standard size walls. This may be difficult for installing batt rock wool insulation material. That's why before performing any operation, you should check the size inside the wall. Usually, the standard size of the wall is about 24 wall and 12 wall, but either one should be checked.
2. Rock wool insulation material
The good and bad of rock wool board, we can obtain through parameters. Density 40kg/m³, heating rate 20°C, melting point 1218°C, water absorption 0.12kg/m³, these are some important characteristics for checking rock wool insulation material. Because better insulation material can save you a lot of trouble during installation.
3. Install the first and second parts
Now you are ready to install batt rock wool insulation material on the internal wall of your home. That's why you should start with installing the first part. Because you won't get batts from the top and bottom. That's why you need to install another layer at the bottom. First, start from the top, then slowly go down. So just take the first layer of rock wool insulation, then push it into the wall. Of course, don't press the rock wool too tightly, this will reduce the r-value. Now it's the installation part. Before installation, you need to measure the use area. Then use a utility knife to cut the excess part of the insulation layer. But make sure to leave about 2cm extra space for tight installation. Then take the cut part and install it into the wall.
The above is the general steps for rock wool board indoor wall installation. Of course, during the installation process we will still encounter various problems, all need to be solved one by one. Therefore, it is recommended to find a professional installation master for construction during installation.
