A1 Non-Combustible Rockwool Sandwich Panels: Fireproof, Energy-Saving Wall & Roof Solutions for Factories, Warehouses & Clean Rooms | Buildgram New Material

Update time : 2026-06-22

Are you struggling to source insulated wall panels that meet strict global fire safety codes while cutting long-term energy costs? Many industrial project owners face three costly headaches with standard insulation panels:

Low fire rating materials fail EN 13501-1 inspections, triggering project delays & safety risks

Ordinary rockwool absorbs moisture, losing insulation performance and shortening service life

Poor acoustic performance creates noisy workshops, violating factory environmental standards

If your project covers manufacturing plants, logistics warehouses, pharmaceutical clean rooms or commercial buildings, you need a reliable, fully certified fireproof enclosure solution — Buildgram A1 Rockwool Sandwich Panels with PU edge sealing.

Buildgram A1 Rockwool PU Edge Sandwich Panel

1. What Makes Buildgram Rockwool Panels a Superior Construction Solution

Buildgram rockwool sandwich panels are high-performance composite insulated panels built with a classic sandwich structure: double-sided metal protective skins + high-density basalt rockwool core. Our panels adopt advanced PU edge sealing technology — a key upgrade over generic rockwool boards:

Moisture Barrier Design

Blocks moisture absorption to prevent core deterioration
Boosts waterproof performance and extends panel service life

Tight Sealing Joint

Seamless tongue-and-groove joint design eliminates thermal bridging & noise leakage

Core Technical Advantages

✅ A1 Grade Non-Combustible, fully compliant with EN 13501-1, withstands temperatures over 1000℃

✅ CE & ISO certified, meets international industrial construction standards

✅ Thermal conductivity ≤0.043 W/m·K, cuts HVAC energy consumption by 20–30%

✅ Sound insulation RW=29–30dB (120kg/m³ core), ideal for noise-sensitive production workshops

✅ Custom core density: 80–150kg/m³; customizable thickness 50/75/100/125/150/200mm

✅ Skin options: galvanized steel, color coated steel, stainless steel (0.4–0.8mm PVDF/polyester coating)

✅ Flexible dimensions: effective width 1090/1190mm, unlimited custom length up to 36m

2. Why PU Edge Sealing Is Indispensable for Long-Term Industrial Projects

Conventional unsealed rockwool panels easily absorb humidity in coastal, humid or cold storage environments, leading to:

Reduced fire resistance performance
Dropped thermal insulation efficiency
Mold growth and structural decay

Buildgram’s integrated PU edge sealing fully wraps the rockwool core, locking out water vapor and maintaining stable insulation & fire performance for 20+ years. It is the optimal choice for long-cycle industrial enclosure systems.
