Seamless Defense | Industrial-Grade Minimalist Surface for Hygienic & Acoustic-Optimized Spaces

1.Ultimate Airtight Advantage: Adopts hermetic sealing technology, achieves nearly zero air permeability via ASTM E283 test. Its precise barrier performance outperforms traditional materials, building a stable protective shield for spaces.

2.Authoritative Fire Certification: Supported by two certifications—EN13501-1:2018 (Class A1) and ASTM E84-24 (Flame Spread Index ≤15), reaches non-combustible A2-s1,d0 grade, suitable for modern building fire protection needs.

3.Architectural-Grade Adaptability: As an ultra-dense finishing layer, it integrates seamlessly with substrates via mechanical/chemical bonding, efficiently enhances ceilings, wall cladding systems and PIR insulation boards to strengthen structural performance.

4.Preferred for Acoustic Scenarios: Complies with ISO 3382-1 reverberation standards, ideal for convention centers, lecture halls and other acoustic-critical spaces. Relying on high-quality fiberglass layers, Fiberglass acoustic panels achieve excellent airborne sound insulation, applied in BREEAM/WELL-certified spaces.

Product application scenarios

Office

Airtight - Premium Plain Pattern Facing excels as ceiling sound panels and wall cladding systems. Beyond enhancing both aesthetics and acoustic performance (NRC 0.85+ for speech privacy), its Class A fire-rated composition complies with OSHA workplace safety regulations. Customizable parameters—including panel thickness (10-50mm), weight (≤3kg/m²), and bespoke color palettes (RAL-certified)—enable seamless adaptation to diverse interior schemes. Whether optimizing contemporary open-plan offices with noise reduction or complementing industrial-chic tech hubs, its modular design supports tailored solutions for HVAC integration and branding alignment.

Conference Room

Fiberglass acoustic panels meet rigorous demands for sound clarity and safety compliance in conference environments. When installed as ceilings or wall systems, their airtight core (air leakage <0.1 CFM/ft² per ASTM E283) ensures sound reflection coefficients ≥0.85, preserving vocal fidelity and preventing speech distortion caused by over-absorption. Engineered with cross-woven fiberglass layers (tensile strength ≥50MPa via ASTM D638), these panels withstand accidental impacts (ASTM D256 Izod test: 3.5 J/m²) while maintaining structural integrity over decades. Ideal for boardrooms requiring uncompromised acoustics and corporate aesthetics, they pair with customizable finishes (Pantone-matched colors, 10-30mm thickness options) to align with architectural branding.

Lecture Hall

Airtight - Premium Plain Pattern Facing emerges as an optimal solution for expansive lecture halls. Engineered with sound-reflective fiberglass acoustic panels (tested to ISO 3382-1 standards), its airtight seal ensures ≥85% sound reflection efficiency, amplifying vocal projection across large spaces while minimizing dead zones. This guarantees undistorted clarity for audiences in rear seating (up to 30m range). Furthermore, the panels’ Class A1 fire rating (EN13501-1) and IP65 waterproof certification safeguard against fire hazards and humidity damage, critical for preserving AV equipment and structural integrity. With impact-resistant cores (50MPa compressive strength), they withstand decades of use in high-traffic academic venues.

Large - scale Performance Venues

For grand auditoriums and concert halls where material performance is non-negotiable, Airtight - Premium Plain Pattern Facing leverages its acoustic-engineered excellence to meet critical demands. The hermetic sealing and 95%+ sound reflectivity (ISO 354-tested) ensure stage audio propagates uniformly across 50-meter spans, delivering pristine audio fidelity to rear-seat audiences.

GRECHO FIBERGLASSCustomer Reviews

The ceiling made of this product is very suitable for use in large open places, such as our newly built lecture hall, where the audience can hear the speaker's voice no matter where they are.
