The core secret of the metal decorative panel: the insulation layer. Have you made the right choice?

Insulation Layer: More Than Just "Heating" - It's the Guardian of Safety and Energy Efficiency

The insulation layer is closely bonded between the panel and the back panel of the metal engraved board. It fulfills three core functions:

Energy conservation and insulation: Significantly improves the insulation performance of the building's enclosure structure, reduces air conditioning energy consumption, and achieves energy conservation and emission reduction.

Safety guarantee: Its fire resistance rating directly affects the overall fire safety of the building. Structural support: Affects the overall flatness, compressive strength and durability of the sheet material.

1.EPS (Extruded Polystyrene Board) - Economical and Practical

Features: Composed of countless sealed air bubbles, it is lightweight, has excellent insulation properties, and has the lowest cost.

Fire resistance rating: Usually B1 (non-flammable). Under the new national standards, it can reach B1 level by adding flame retardants, but the core is still an organic material.

Application scenarios: Suitable for ordinary civil and industrial buildings with cost sensitivity and a B1-level fire resistance requirement.

One-sentence summary: A cost-effective choice, but with a ceiling in terms of fire resistance performance. 

 2. XPS (Extruded Polystyrene Board) - High-strength Moisture-proof Type

Features: The closed-cell structure is denser, with high strength, extremely low water absorption rate, and excellent moisture-proof performance.

Fire resistance rating: Mostly B1 level (non-flammable).

Application scenarios: Suitable for foundation parts or humid environments with special requirements for compressive strength and moisture resistance.

One-sentence summary: This EPS is "more sturdy and moisture-proof", but fire resistance remains the key consideration. 

3. PU/PIR (Polyurethane/Polyisocyanurate) - Highly Energy-Efficient

Features: One of the most efficient insulation materials available today (with a low thermal conductivity), the insulation layer can be made thinner. PIR is an improved version of PU and has better heat resistance and fire resistance.

Fire Resistance Rating: PU is typically B1 grade, while high-quality PIR can reach B1 grade or even higher.

Application Scenarios: Suitable for high-end energy-efficient buildings with strict requirements for insulation performance and panel thickness.

One-sentence summary: The "top student" in the insulation field, but with relatively higher costs. 

4. Rock wool / Mineral wool - Secure Fire Barrier

Features: Made from natural minerals, with a fibrous structure, it is an inorganic material. The greatest advantage is its excellent fire resistance and good sound absorption properties.

Fire resistance rating: A (non-combustible), it is a mandatory or preferred material for fire safety requirements in strict environments. Applicable scenarios: High-rise buildings, public buildings, densely populated areas and any projects with explicit A-level fire protection requirements.

Summary in one sentence: It is a safety guard, but with a high density. Attention should be paid to its long-term moisture resistance and bonding process.
