Here are some common fireproof and energy-saving materials classified as A-grade, which are widely used in construction for their excellent fire resistance and insulation properties:
1. Polyurethane Fireproof Board – Known for its high thermal insulation performance and flame retardant properties.
2. Rock Wool Board – Offers good fire resistance, sound absorption, and thermal insulation capabilities.
3. Inorganic Silicate Foam Board – Lightweight, non-combustible, and provides excellent thermal insulation.
4. Phenolic Fire Board – Highly resistant to fire and has a low thermal conductivity, making it ideal for insulation.
5. Inorganic Thermal Insulation Mortar with Hollow Microbeads (Perlite) – Combines the benefits of inorganic materials with lightweight, insulating microbeads for improved energy efficiency.
Other organic materials typically fall under Class B, which means they have lower fire resistance compared to A-grade materials. Choosing A-grade materials is crucial for ensuring safety and compliance with fire regulations in building projects.
