For decades, asbestos sheet has been a cornerstone material in industries requiring exceptional fire resistance, thermal insulation, and durability. At Kaxite Sealing, we specialize in providing high-performance, modern asbestos-cement sheets engineered to meet rigorous safety and performance standards for contemporary construction and industrial applications.
Historically valued for its fibrous mineral properties, today's asbestos cement sheets are manufactured under strict controls. Our products at Kaxite Sealing leverage the material's inherent strengths—such as non-combustibility, resistance to weathering, and excellent acoustic insulation—while being fabricated in controlled environments to ensure product integrity and safety. These sheets are an ideal solution for roofing, cladding, partitioning, and fireproofing in factories, warehouses, agricultural buildings, and selected industrial settings.
Our asbestos sheets are engineered with precision. Below are the critical parameters that define their quality and suitability for various projects.
| Property | Standard Value | Test Method / Notes |
|---|---|---|
| Density | 1.6 - 1.8 g/cm³ | ASTM C1185 |
| Flexural Strength | ≥ 16 MPa | Minimum average; key for load-bearing applications |
| Thermal Conductivity | 0.4 - 0.6 W/m·K | Provides effective thermal insulation |
| Fire Resistance Rating | Class A (Non-combustible) | ASTM E136 / BS 476 Part 4 |
| Water Absorption | < 20% by weight | 24-hour immersion test; indicates weather durability |
| Acoustic Absorption | Moderate to High | Effective for noise reduction in industrial settings |
| Sheet Type | Length (mm) | Width (mm) | Thickness (mm) | Sheets per Pallet |
|---|---|---|---|---|
| Corrugated Roofing | 1830, 2440 | 965 | 4.5, 6.0 | 40-60 |
| Flat Cladding | 2440, 3050 | 1220 | 4.0, 5.0, 6.0 | 50-80 |
| Fire Protection Board | 2440 | 1220 | 6.0, 9.0, 12.0 | 30-50 |
Q: Is asbestos sheet still safe to use?
A: When we refer to modern asbestos cement sheets, safety is paramount. The asbestos fibers in our Kaxite Sealing sheets are tightly bound within a solid cement matrix. This encapsulation prevents the release of fibers into the air under normal conditions of use, such as when the sheet is intact and installed. The primary health risk historically associated with asbestos arose from prolonged inhalation of high concentrations of loose, airborne fibers, typically during unregulated mining, milling, or the abrasive processing of old materials. Our products are manufactured for applications where the sheet remains undisturbed and are subject to strict quality control.
Q: What safety precautions are necessary during installation?
A: We recommend treating all building materials with respect. For cutting or drilling Kaxite Sealing asbestos cement sheets, use hand tools or power tools equipped with dust extraction attachments (e.g., HEPA vacuum). Work should be conducted in well-ventilated areas, and installers should wear appropriate personal protective equipment (PPE) such as a P2/P3 rated dust mask and gloves. Wet methods can be used to suppress dust. It is crucial to follow local occupational health and safety regulations regarding the handling of asbestos-containing materials.
Q: What are the main advantages of using asbestos cement sheets over metal or plastic alternatives?
A: Asbestos cement sheets offer a unique combination of benefits: They are inherently non-combustible (unlike many plastics), providing a genuine Class A fire rating. They have excellent dimensional stability and do not warp or corrode like metals can in certain chemical environments. They also provide better thermal and acoustic insulation than thin metal sheets. For cost-effective, durable, and fire-resistant cladding or roofing in industrial buildings, they often present a superior long-term value proposition.
Q: Can these sheets be used for interior applications?
A: Yes, specifically our flat sheet products are suitable for selected interior applications such as fire-rated partitions, linings for plant rooms, or as a substrate in areas requiring non-combustibility. For interior use, it is essential that the sheets are properly sealed, painted with a suitable sealant, or covered to ensure a finished surface and to prevent any potential surface fiber release, however minimal. Always check local building codes for interior use of cement-based panels.
Q: How do I cut and fix an asbestos cement sheet?
A: Cutting can be done with a score-and-snap method using a carbide-tipped tool for straight lines, or with a diamond-tipped blade in a power saw equipped with dust suppression. For fixing, pre-drill holes slightly larger than the fastener diameter to prevent cracking. Use corrosion-resistant fixings (e.g., galvanized or stainless steel screws, hooks, and bolts) with neoprene or EPDM sealing washers to create a watertight seal and accommodate minor thermal movement. Always follow the fixing patterns recommended by your structural engineer or our Kaxite Sealing technical guides.
Q: What is the expected lifespan of a Kaxite Sealing asbestos sheet roof?
A: With proper installation and maintenance, our asbestos cement roofing sheets have a service life exceeding 50 years. Their resistance to UV radiation, moisture, and corrosion contributes to this longevity. Maintenance primarily involves keeping gutters and valleys clear of debris and periodically inspecting fixings and sealants. The material does not require painting for protection, though it can be painted for aesthetics using a masonry paint.
Q: Are there legal restrictions on using asbestos sheets in my country?
A: Legislation varies significantly by country and region. Some countries have banned all forms of asbestos, while others permit the use, import, or manufacture of asbestos-cement products under specific regulations. It is the sole responsibility of the purchaser to ascertain and comply with all national, state, and local laws, regulations, and codes governing the purchase, use, application, and disposal of these products. Kaxite Sealing can provide product specifications but does not provide legal compliance advice.
Q: How should old or damaged asbestos sheets be disposed of?
A: Under no circumstances should asbestos cement sheets be disposed of with general construction waste. They are classified as hazardous waste in most jurisdictions. Disposal must be carried out by licensed hazardous waste contractors in accordance with local environmental protection regulations. This typically involves careful dampening, double-bagging in labeled hazardous waste bags, and transport to designated landfill facilities equipped to handle asbestos-containing materials. Never break or crush sheets during removal.
