Building
Thermal and fire insulation for buildings — external walls, roofs, fire compartments, pipe and acoustic systems using rock wool, glass wool, ceramic fiber and calcium silicate.
Buildings are among the largest application fields for high-temperature insulation materials. The core requirements are fire separation, thermal energy saving and acoustic comfort. Rock wool's A-class non-combustibility makes it the default choice for external wall and fire-compartment systems; glass wool leads in acoustic and low-cost interior insulation; ceramic fiber serves high-temperature fire barriers and kitchen equipment; calcium silicate provides load-bearing fire-door cores and partition walls.
Material Comparison
| Material | Best fit | Service temp | Key advantage |
|---|---|---|---|
| Rock wool | External walls, fire barriers, roofs | 600-800°C | A-class fire, high tensile strength |
| Glass wool | Interior walls, acoustic ceilings, HVAC | 250-450°C | Lightweight, low cost, sound absorption |
| Ceramic fiber | Fire shutters, kitchen equipment, seals | 800-1200°C | Thin, light, high-temp fire barrier |
| Calcium silicate | Fire doors, partitions, tunnels | 600-1000°C | High compressive strength, structural |
Application Scenarios
Building Application Scenarios
- External wall insulation systems — rock wool board/felt as an A-class non-combustible envelope for high-rise facades, combining fire safety with thermal performance.
- Roof insulation — rock wool and glass wool layers on commercial and industrial roofs reduce heat gain and cooling load.
- Fire barriers & compartments — rock wool in fire walls, fire doors and fire stops achieves fire ratings beyond 3 hours.
- Building pipe insulation — rock wool and glass wool on hot-water and steam lines prevent heat loss and burn risk.
- Acoustic ceilings — glass wool as the primary absorber in theaters, concert halls and offices.
- Fire shutters & kitchen equipment — ceramic fiber liners in fire curtains and large cooking appliances.
- Fire door cores & partitions — calcium silicate boards for fire-rated doors and public-space fire walls.
- Tunnel fire layers — calcium silicate boards in metro and road tunnels, resistant to heat, moisture and corrosion.

Frequently asked questions
Which insulation is best for high-rise exterior walls? +
A-class non-combustible rock wool boards are the standard choice for tall-building external walls, combining fire safety with low thermal conductivity of about 0.03-0.04 W/m·K.
Can these materials serve as fire barriers? +
Yes. Rock wool fire barriers and calcium silicate core boards achieve fire ratings above 3 hours for firewalls, fire doors and fire partitions.
Do you supply acoustic insulation solutions? +
Yes. Glass wool panels and acoustic ceiling tiles provide sound absorption for auditoriums, meeting rooms and ventilation ducts.
