Importance of Building Insulation and Isogam using Bitumen
Proper insulation is a crucial aspect to consider after completing the construction of a house. It is particularly important to ensure that the building, especially the roof, is resistant to rainwater. To achieve this, many people opt for isogam, a process that involves applying bitumen as a waterproofing material. It is recommended to use export bitumen for this purpose. Bitumen 7060 is one of the popular types available in the market, and its demand is thriving.
In addition to bitumen, several tools and equipment are required for a successful isogam process. These include:
- Carpet Cutting Blade: This tool is essential for cutting the isogam to fit the size of the building's roof accurately. It ensures precise and proper installation.
- Broom: Before applying isogam, it is crucial to clean the roof surface thoroughly from any dust or debris. A broom is used to sweep and prepare the surface for the isogam application.
- Spark Lighter: A spark lighter is necessary to ignite the flame of the isogam lamp. It is advisable to use a spark lighter with a long handle to prevent accidental burns.
- Torch: The torch is a primary tool used for leveling surfaces during the isogam process. It is used to heat the isogam and adhere it to the desired surface. The torch's burners are lit using a lighter.
- Gas Capsule (Liquid Gas): Burners are connected to a gas capsule containing liquid gas to provide heat for the isogam application. Typically, one gas capsule is sufficient for approximately 50 meters of isogam work.
- Kamcheh and Trowel: These tools are used for welding isogam bands together, ensuring a secure and effective seal. They play a crucial role in achieving proper insulation.
- Powder Fire Extinguisher: As isogam work involves the use of fire, it is essential to have a powder fire extinguisher readily available for necessary safety measures. Fire safety should not be overlooked in this profession.
- Rope and Pulley: When isogam work is performed in multi-story buildings, a rope and pulley system is necessary to transfer the isogam materials efficiently. This equipment should be accessible for the person carrying out the work.
- Personal Protective Equipment: Given the involvement of fire, it is essential to wear special clothes, along with protective glasses, helmets, and gloves. These safety measures ensure the well-being of individuals during the isogam process.
Taking these necessary precautions, using appropriate tools, and wearing protective gear contribute to a safe and successful isogam operation.
Certainly! Welding isogam bands using a kamcheh and trowel is an important step in the isogam process, ensuring a secure and effective seal between the bitumen strips. Here's a detailed explanation of the process:
- Preparation: Before starting the welding process, the isogam bands should be properly positioned and aligned on the surface. The bands are typically overlapped, with a specific overlap width depending on the manufacturer's recommendations.
- Heating the Kamcheh: The kamcheh is a specialized tool used for welding isogam bands. It consists of a metal plate with a handle. The kamcheh is heated using a torch until it reaches the required temperature. The temperature may vary depending on the type of bitumen being used.
- Applying Bitumen: Once the kamcheh is heated, bitumen is applied to the overlapping section of the isogam bands. The bitumen should be heated until it becomes molten and easily spreadable. This can be achieved by heating the bitumen directly with the torch or by using a separate container to melt the bitumen and then applying it with a brush or trowel.
- Welding Process: With the bitumen applied to the overlapping section, the heated kamcheh is pressed firmly against the bitumen. The kamcheh is then moved along the length of the overlap, pressing and melting the bitumen in a controlled manner. This process creates a strong bond between the isogam bands, effectively sealing the joint.
- Smoothing and Finishing: After the welding process, a trowel is used to smooth the welded area and ensure a uniform surface. The trowel helps to evenly distribute the bitumen and create a seamless appearance. Care should be taken to avoid excessive pressure or dragging that could disrupt the integrity of the joint.
- Cooling and Inspection: Once the welding process is complete, it is important to allow the welded area to cool and solidify. This ensures that the joint is securely sealed. After cooling, a visual inspection should be conducted to verify the quality of the weld and ensure there are no gaps or defects.
It's worth noting that the specific procedures and tools used for welding isogam bands may vary based on the manufacturer's guidelines and the specific requirements of the project. Proper training and experience in using the kamcheh and trowel, as well as following safety precautions, are essential for achieving reliable and effective welds in isogam applications.
During the welding process of isogam bands using the kamcheh and trowel with bitumen, several challenges or issues may arise. Here are some common ones:
- Improper Heating: Achieving the correct temperature of the kamcheh is crucial for a successful weld. Insufficient heating can result in insufficient melting of the bitumen, leading to a weak bond. Conversely, overheating can cause the bitumen to burn or degrade, affecting the quality of the weld.
- Inadequate Surface Preparation: Insufficient cleaning or preparation of the surface before welding can impede the adhesion of the bitumen. Dust, debris, or moisture on the surface can prevent proper bonding, resulting in weak or compromised welds.
- Incorrect Overlap: The overlap width between isogam bands is essential for creating a strong and watertight seal. If the overlap is too narrow, it may not provide sufficient coverage, leading to potential leaks. Conversely, if the overlap is too wide, it can create excessive thickness and result in an uneven or weak joint.
- Insufficient Pressure: Proper pressure application during the welding process is critical for ensuring a secure bond between the isogam bands. Insufficient pressure or improper technique may lead to incomplete fusion of the bitumen, resulting in weak or dislodged welds.
- Uneven Application: Inconsistent or uneven application of bitumen along the overlap can create variations in thickness and compromise the integrity of the weld. It is important to maintain a consistent and uniform layer of bitumen throughout the welding process.
- Lack of Skill or Experience: Welding isogam bands with a kamcheh and trowel requires skill and experience to achieve satisfactory results. Inexperienced operators may struggle with maintaining the correct temperature, applying the right pressure, or achieving proper technique, leading to subpar welds.
- Environmental Factors: Environmental conditions, such as extreme temperatures, high humidity, or windy conditions, can affect the welding process. For instance, rapid cooling due to cold weather can impact the fusion of the bitumen, while excessive wind can make it challenging to maintain a steady flame or heat distribution.
To overcome these challenges and ensure successful welding, it is recommended to follow manufacturer guidelines, receive proper training, and adhere to best practices for isogam application. Regular inspection and quality control checks during and after the welding process can help identify and address any issues promptly.
