1.Product Overview
Teralong Perforated Acoustic Calcium Silicate Board is a multifunctional building material developed by Tairong Building Materials Co.,Ltd.Combining sound absorption,structural strength,and decorative appeal,the board is manufactured using high-density calcium silicate as the base,precision perforation on the surface,and acoustic backing materials.It offers excellent acoustic performance,A1-level fire resistance,moisture resistance,and outstanding dimensional stability.
It is widely used in ceiling and wall systems of large public buildings such as metro stations,airport terminals,hospitals,schools,office buildings,and exhibition centers—ideal for environments requiring both high acoustic performance and structural reliability.
2.Structure&Acoustic Principle
Teralong boards adopt a“micro-perforation+acoustic backing”structure,providing effective sound absorption:
•Base Layer:High-strength calcium silicate board made from silicon materials,calcium compounds,and reinforcement fibers.Produced through high-temperature autoclaving,it ensures excellent strength,dimensional stability,fire resistance,and moisture resistance.
•Perforated Layer:Precision-cut perforations(round,square,slotted,etc.)using automated equipment.Perforation rates typically range from 10%to 20%,enabling sound wave penetration.
•Acoustic Backing Layer:Options include fiberglass mat,nonwoven fabric,or mineral wool,which absorb transmitted sound and reduce reflection and reverberation.
•Edge Finish:Available in square edge,bevel edge,and sealed edge options to ensure visual consistency and mechanical strength.
3.Key Performance Features
1.Excellent Sound Absorption
NRC up to 0.75–0.85,particularly effective in the mid-to-high frequency range.Reduces reverberation and improves speech clarity and acoustic comfort.
2.A1-Level Fire Resistance
Made of non-combustible materials,the board meets GB 8624 A1 standards,suitable for buildings with stringent fire safety codes.
3.Moisture&Mold Resistant
High resistance to humidity—boards won’t deform,warp,or mildew,making them ideal for underground or humid spaces.
4.Durable&Impact-Resistant
With higher density and structural integrity than traditional gypsum or mineral wool boards,it offers enhanced longevity and low maintenance.
5.Customizable Appearance
Available in custom colors and textures;compatible with lighting systems,ventilation grilles,and access panels for integrated ceiling design.
6.Green&Safe
Free of asbestos,formaldehyde,and harmful emissions.Certified as a green building material for environmentally sensitive applications like schools and hospitals.
