Roof Tile Technical Specifications and Standards

At Sela Roof Tile, we are committed to providing high-quality roof tiles that meet industry-leading standards for performance and durability. This page outlines the key technical specifications, standards, and certifications that our roof tiles comply with. Understanding these factors will help you make informed decisions when selecting roof tiles for your project.

1. Material Specifications

Our roof tiles are crafted from a variety of materials, each offering distinct advantages in terms of strength, durability, and aesthetic appeal. Below are the key material specifications:

• Clay Roof Tiles:

  • Composition: Made from natural clay, fired at high temperatures to enhance durability and resistance.

  • Water Absorption: Less than 10%, making them highly resistant to moisture and freezing conditions.

  • Weight: Typically ranges from 4 to 5 kg per tile.

  • Fire Resistance: Class A (non-combustible).

• Concrete Roof Tiles:

  • Composition: Made from cement, sand, and aggregates. Concrete tiles are reinforced for strength and can withstand heavy loads.

  • Water Absorption: Less than 10%, ensuring long-term performance in wet climates.

  • Weight: Approximately 4 to 6 kg per tile.

  • Fire Resistance: Class A (non-combustible).

• Metal Roof Tiles:

  • Composition: Made from steel, aluminum, or copper with protective coatings for enhanced durability and corrosion resistance.

  • Weight: Lightweight, generally around 1 to 2 kg per tile.

  • Fire Resistance: Class A (non-combustible), making them ideal for fire-prone areas.

  • Coatings: Available in a variety of finishes, including painted, galvanized, and zinc-coated.

2. Performance Standards

To ensure the highest quality and reliability, our roof tiles undergo rigorous testing to meet various performance standards:

• ASTM International (American Society for Testing and Materials):
  We adhere to ASTM standards for roofing materials, ensuring that our tiles perform optimally under various environmental conditions. Relevant ASTM standards include:

  • ASTM C1167: Standard Specification for Concrete Roof Tiles.

  • ASTM C1492: Standard Specification for Clay Roof Tiles.

  • ASTM E108: Fire Test for Roof Coverings.

• ISO Standards:
  Our roof tiles are manufactured in compliance with ISO 9001 for quality management and ISO 14001 for environmental management. This ensures that our products are made using sustainable practices and meet global quality requirements.

• BREEAM Certification:
  For environmentally-conscious projects, we offer roof tiles that comply with BREEAM (Building Research Establishment Environmental Assessment Method) standards, contributing to sustainability goals in green building projects.

3. Durability and Weather Resistance

Roof tiles are designed to withstand a variety of weather conditions, from high winds to extreme temperatures. Here are some of the key performance metrics:

• Wind Resistance:
  All of our roof tiles are tested for wind uplift resistance. Depending on the type of tile and installation method, our tiles can withstand winds up to 150 mph (241 km/h), making them suitable for hurricane-prone regions.

• Thermal Performance:
  Roof tiles help regulate building temperature by providing insulation against heat and cold. The thermal conductivity of our tiles is optimized for energy efficiency, contributing to lower heating and cooling costs.

• Freeze-Thaw Resistance:
  Our clay and concrete tiles undergo freeze-thaw testing to ensure they remain durable and intact under freezing conditions. These tiles are built to resist cracking and damage caused by water absorption and freezing.

4. Fire Safety Standards

Safety is a top priority, and all our roof tiles comply with rigorous fire safety standards. Most of our tiles are classified as Class A (non-combustible), which is the highest fire-resistant rating available. This makes them ideal for areas prone to wildfires or regions with strict fire safety regulations.

5. Installation Specifications

Correct installation is crucial for roof tile performance. Here are some key installation guidelines that ensure optimal performance:

• Tile Layout:
  Tiles must be installed following specific layout patterns to ensure uniformity, proper drainage, and secure fastening. A proper layout prevents wind uplift and water penetration.

• Fastening Methods:
  Depending on the type of tile, specific fasteners (e.g., clips, nails, screws) must be used to secure the tiles. The installation must adhere to local building codes and manufacturer specifications.

• Underlayment and Waterproofing:
  An appropriate underlayment (such as a synthetic membrane) is essential for creating a waterproof barrier beneath the roof tiles. This prevents leaks and extends the life of the roof.

6. Compliance with Local Building Codes

All of our roof tiles comply with local and national building codes, which may vary depending on the location. It’s important to consult with a professional roofer or contractor to ensure that the selected roof tiles meet your area’s specific building regulations.

7. Environmental Impact and Sustainability

We are committed to reducing the environmental impact of our roof tiles:

• Recyclability: Most of our tiles, particularly clay and concrete tiles, are fully recyclable. At the end of their lifespan, the tiles can be processed and repurposed.

• Eco-Friendly Production: Our manufacturing process follows ISO 14001 standards for environmental management, minimizing waste and energy usage during production.

• Sustainable Materials: We prioritize the use of sustainable materials, such as recycled aggregates in concrete tiles and natural clay for ceramic tiles.
