Phenofelt Insulation
Pheno Felt insulation has one side coated with aluminum, and this aluminum coating makes rock wool not only a sound and heat insulator but also a moisture insulator.
Pheno Felt is produced in standard thicknesses with densities ranging from 30 to 50 kilograms per cubic meter. This insulation is used in places such as false ceilings and warehouse roofs, conference room ceilings, home heating and cooling systems, and air conditioning ducts.
What is Pheno Felt Insulation?
Pheno Felt insulation or Phenofelt is one of the best insulation products in various industries, attracting the attention of many engineers and contractors due to its unique features. By using Pheno Felt insulation, it is possible to reduce energy consumption, improve safety, and increase efficiency in different projects.
However, a question that may arise for many is: How is Pheno Felt insulation made? What materials are used in its production? And what compounds give this product its insulating properties? In this article, we will discuss the production of Pheno Felt insulation, as well as how to purchase and install it, and provide you with all the necessary information on this topic.
The production process of Pheno Felt insulation includes the following steps:
1. Preparing Raw Materials for Pheno Felt Insulation:
Basalt stones are extracted as the main raw material. These stones are ideal for producing Pheno Felt insulation due to their thermal resistance and suitable physical properties.
2. Melting the Stones:
Basalt stones are heated to high temperatures (around 1500°C) in special furnaces until they melt.
3. Fiberization:
The molten material is transformed into thin, long fibers using specialized equipment. These fibers are arranged together to form the structure of Pheno Felt insulation.
4. Adding Binders to Pheno Felt Insulation:
To increase the strength and cohesion of the rock wool fibers, binders are added. These materials cause the fibers to adhere to each other, creating a stronger structure.
5. Shaping and Compressing:
The rock wool fibers are shaped into blankets or rolls and then compressed to achieve the desired thickness and density.
6. Cutting and Packaging:
The final Pheno Felt insulation product is cut into standard sizes and packaged for easier transportation and use.
Pheno Felt insulation is produced in rolls measuring 10 × 1.2 meters and is usually supported with a cover or reinforced aluminum paper backing on kraft paper. This insulation is available in 3 different models: bare rock wool (without covering), paper-backed rock wool (with kraft paper covering), and foil-faced rock wool (with reinforced aluminum thread covering).
The three characteristics of length, width, and thickness of rock wool, as dimensions, indicate the physical sizes of the rock wool.
Length: The length of Pheno Felt insulation rolls can vary, but it is usually between 5 to 10 meters. These lengths are chosen for easier transportation and installation.
Width: The standard width of Pheno Felt insulation rolls is typically 1 meter. However, in some cases, custom widths may also be produced.
Thickness: The thickness of Pheno Felt insulation usually ranges from 3 to 10 centimeters. The selection of the appropriate thickness depends on the insulation requirements and specific application.
Technical Specifications of Pheno Felt
The technical specifications of Pheno Felt insulation may include the following performance and technical characteristics:
-Thermal Conductivity: A measure indicating how quickly a material conducts heat; the lower this coefficient, the better the material is as a thermal insulator.
-Density: A measure indicating the mass of a material per unit volume.
Density refers to the compactness or mass per unit volume of a material and, in Pheno Felt insulation, indicates the weight of the rock wool per unit volume (usually kilograms per cubic meter). The density of Pheno Felt insulation plays a crucial role in determining its physical properties and applications. Depending on the density, Pheno Felt insulation can be used for various applications, including thermal, acoustic, and fire-resistant insulation.
-Compression Strength: Indicates how much a material can withstand compressive forces without breaking or permanent deformation.
-Tensile Strength: Indicates how much a material can withstand tensile forces without breaking.
-Sound Absorption Coefficient: Indicates how much of the incoming sound energy is absorbed by the material, preventing reflection.
-Operating Temperature Range: The temperature range within which a material or device can operate correctly without loss of efficiency or damage.
Applications and Features of Pheno Felt Insulation
This type of Pheno Felt insulation is primarily used for covering false ceilings, warehouse roofs, conference hall ceilings, industrial and prefabricated buildings, air ducts, and HVAC systems. The applications of Pheno Felt insulation are similar to those of rock wool blanket insulation, with the difference that it operates at lower temperatures and has a lower density, making it more cost-effective. The main uses of Pheno Felt insulation fall within low to medium temperature ranges. Medium-density Pheno Felt insulation is highly suitable for insulating curved surfaces, chimneys, tanks, reservoirs, medium and low-temperature pipes, large PVC and steel pipes, workshop roofs, attics, and low-temperature equipment.
Among the most important features of Pheno Felt insulation are the following:
- High sound absorption
- Corrosion resistance
- Stable physical and chemical properties
- Fire spread prevention
- Asbestos-free
- Easy transportation and installation
- Excellent thermal and acoustic insulation properties
- High resistance to fire and flame spread
- Very good flexibility and lightweight
- Corrosion resistance
- Resistance to chemical and biological contaminants
- Impact resistance
- Easy and quick installation
- Very simple transportation and storage
- Very cost-effective and affordable
- Excellent durability, maintaining its physical and chemical properties over the long term.
Installation Method of Pheno Felt Insulation
The method of installing Pheno Felt insulation on roofs is usually as follows:
In applications such as warehouses, villa roofs in humid areas, gazebos, storage facilities, and workshops, sloped roofs are commonly used. Insulating sloped roofs is essential to prevent heat exchange, protect against rain and moisture penetration, and block sound transmission. Failure to do so can cause significant problems for users.
Generally, foil-faced Pheno Felt insulation is used for insulating sloped roofs. In such spaces, due to human activities, vapor from breathing, cooking, etc., rises upward. Since the use of false ceilings in sloped structures is not common, the vapor directly enters the rock wool thermal insulation and damages it. The foil layer installed on one side of the Pheno Felt insulation is designed to prevent vapor penetration into the insulation. Foil-faced Pheno Felt insulation is typically produced in 5 cm thickness and densities of 30 and 50 kilograms per cubic meter. Using higher density insulation increases the economic burden on the project but provides higher thermal resistance. The decision in this regard depends on the building’s usage and the project’s economic conditions.
7. Important Tips for Installing Pheno Felt Insulation on Roofs
- Use Safety Equipment: When installing Pheno Felt insulation, ensure the use of safety equipment such as helmets, goggles, and gloves. Also, make sure the work environment is safe and stable.
- Improve Insulation Coverage: Ensure that no part of the roof remains uncovered by Pheno Felt insulation. This is crucial to prevent heat and sound loss in the building.
- Proper Compression: After installing Pheno Felt insulation, the compression process should be performed carefully using appropriate equipment. This ensures the insulation fits well into the roof, leaving no gaps or weak points.
- Adhere to Standards: Pay special attention to standards and guidelines during installation. This includes using suitable materials, correct installation methods, and following safety regulations.
- Moisture and Waterproofing: Ensure the roof is properly waterproofed and no area is damp. In humid environments, use water-resistant rock wool insulation.
- Proper Ventilation: Ensure adequate ventilation in the installation area to prevent moisture-related issues and decay.
- Specialist Consultation: If needed, consult experienced specialists in rock wool insulation installation to choose the right methods and materials for your roof.
Adhering to these important tips when installing blanket insulation on the roof helps improve the insulation performance and efficiency of your building.
Price of Blanket Insulation
The price of blanket insulation is higher than that of fiberglass insulation. This is due to its superior thermal and acoustic resistance compared to fiberglass. Additionally, there are factors that significantly affect the price of blanket insulation. It is often compared to fiberglass insulation. Blanket insulation is produced with various coatings that prevent moisture from reaching the surface, and some of these coatings increase the tensile strength of the insulation, leading to a higher price for Pheno Felt insulation.
Thickness is also one of the reasons for the price increase in blanket insulation. Thickness can enhance the insulation’s resistance to heat, cold, and thermal changes. Density is another crucial factor affecting the price of this mineral non-combustible insulation. The higher the density of the blanket insulation, the greater its resistance to heat and direct fire. In fact, thickness and density are two important factors in fire resistance. Therefore, the price of Pheno Felt insulation depends on its density, type of coating, and thickness.
