In this article, join Faraz Oil Bitumen Refinery to explore the different types of building bitumen, their characteristics, and the best options for insulation projects.
Building insulation is one of the most critical stages in construction, playing a key role in increasing the durability and efficiency of structures. Protecting buildings from moisture penetration is a primary challenge in any construction project, as moisture can damage the structure, reduce the lifespan of materials, and increase maintenance and repair costs. Among the various materials available, building bitumen stands out as an essential component for effective insulation.
Various types of building bitumen are available in the market, specifically designed for waterproofing and bitumen coating applications. Each type of bitumen is tailored for specific uses, depending on its composition and unique features.
Types of Building Bitumen for Insulation
For waterproofing and bitumen coating applications, various types of building bitumen are used, each with distinct features and specifications suited to different needs. Below, we delve into the details of each type of building bitumen and its applications.
-
Building Bitumen 60.70 (Soft Bitumen)
Building bitumen 60.70, also known as soft bitumen, is one of the most widely used types. It becomes fluid at a softening point temperature of 49-52°C. With a penetration grade of 60 to 70 tenths of a millimeter in the Marshall needle test, it has a soft and sticky texture. At higher temperatures, it becomes fully fluid, making it highly suitable for applications requiring deep penetration and high adhesion.
-
Applications
Due to its exceptional adhesive properties, soft bitumen is commonly used for bonding waterproofing membranes (like bituminous sheets) and forming the initial coating layer in bitumen waterproofing. This bitumen effectively bonds various surfaces, penetrating the substrate well due to its fluidity and forming a strong waterproof layer. It is also utilized in protecting concrete and cement structures from moisture and is an ideal choice for areas requiring a strong and adhesive initial layer.
-
Building Bitumen 90.15 (Hard Bitumen)
Hard bitumen 90.15 is one of the toughest types of building bitumen, becoming fluid at 90°C. It has a penetration grade of 15 tenths of a millimeter in the Marshall needle test and appears dry and brittle at normal temperatures. Its high thermal resistance and rigid structure make it an excellent choice for high-temperature regions.
-
Applications
Hard bitumen is primarily used in combination with soft bitumen for insulation in extremely hot areas. Additionally, it is employed in insulating oil and gas pipelines, cement water pipes, and water channel linings. Its resistant properties ensure effective performance even in harsh environmental conditions.
This type of bitumen is also applied in infrastructure projects to create protective layers resistant to water and moisture penetration. Hard bitumen 90.15 is a professional and reliable choice for areas requiring robust, long-lasting insulation.
-
Mixed Building Bitumen (85.25 Mixed Bitumen)
Mixed building bitumen 85.25 is a combination of solid and semi-solid bitumen, softening at 85°C. With a penetration grade of 25 tenths of a millimeter in the Marshall needle test, it is solid at normal temperatures and becomes semi-solid in warm climates. These characteristics make it well-suited for applications requiring durability and moderate flexibility.
-
Applications
Mixed bitumen is widely used for bitumen coating and insulation in construction. It is particularly ideal for insulating roofs, bathrooms, parking areas, and kitchens. Its thermal resistance and ability to prevent moisture infiltration make it a preferred choice for moderate and warm climates. In addition to insulation, mixed bitumen is used for coating cement surfaces and providing a protective layer against moisture. Due to its adhesive properties, it is also extensively used for installing waterproofing membranes and creating the initial coating in building structures.
-
Polymer-Modified Building Bitumen
Polymer-modified building bitumen is one of the most advanced types, produced by adding polymers such as SBS (styrene-butadiene-styrene) or APP (atactic polypropylene) to standard bitumen. These polymers enhance the mechanical and chemical properties of bitumen, including flexibility, crack resistance, and longevity. The precise combination of polymers and bitumen in the production process ensures tailored properties for specific construction needs.
-
Applications
Polymer bitumen offers exceptional thermal resistance, providing stable performance in extreme temperatures. Its high flexibility prevents cracking or separation over time, making it ideal for long-term projects. Resistance to water penetration, UV radiation, and chemicals further enhances its versatility for sensitive applications.
Polymer-modified bitumen is widely used for insulating roofs, bridges, tunnels, and water tanks. It is also ideal for coating concrete, metal, and road structures due to its resistance to moisture and temperature changes. In road construction, it is used for creating durable asphalt with extended lifespan and higher resistance to traffic loads.
Buying Guide for Building Bitumen
To purchase the best type of building bitumen for insulation and waterproofing, consider the following key factors: First, select the right bitumen type based on your specific needs; as discussed, each type has unique features. Second, pay attention to bitumen standards; high-quality bitumen should come with valid certifications. Additionally, resistance to water, UV, and various temperatures are crucial characteristics. Moreover, compare prices and quality from reliable sources to make an informed choice. Lastly, for effective insulation, choose bitumen with good adhesion and elasticity for optimal results.
Conclusion
Building bitumen is a vital material in the insulation industry, known for its unique capabilities against moisture, temperature, and pressure. Selecting the right type of high-quality bitumen can significantly impact the durability and efficiency of insulation systems. Therefore, prioritizing bulk bitumen quality and standards can prevent additional costs and potential damage to buildings.
