When fire safety cannot be compromised

A

Non-combustible Class A core

Spun from molten basalt rock at 1500 °C, the mineral wool core is fundamentally inorganic and will not burn, melt or release toxic smoke at temperatures up to 1000 °C. Tested to GB 8624 Class A1 / EN 13501 A2-s1,d0.

Mandatory for buildings over 24 m, public-occupancy structures, oil & gas facilities, lithium battery factories and data centres in most jurisdictions.

dB

Acoustic & thermal stability

Unlike foam cores, mineral wool retains its insulation value through repeated thermal cycles and decades of service — no shrinkage, no off-gassing, no R-value decay.

Fibrous structure absorbs airborne sound, delivering Rw values up to 35 dB — ideal for noisy production halls, music venues and any roof exposed to rain impact.

Note: Surface load capacity values represent maximum allowable deflection limits. P = uniform load (kg/m²); L = span (mm). Calculations based on Rockwool core density 100–140 kg/m³.

Buildings where Class A fire performance is mandated

01 Lithium Battery & EV Factories

Mandatory non-combustible envelope to contain thermal runaway events. Compliant with GB 51377 fire codes.

02 Data Centres & Telecom

Zero combustible material above critical IT infrastructure. Absorbs HVAC and equipment noise.

03 Petrochemical Facilities

Refineries, LNG depots and chemical plants where any organic material in the envelope is prohibited.

04 High-occupancy Public Buildings

Stadiums, exhibition halls, hospitals, schools — any building over 24 m or with high public occupancy.

Glass Wool Core · Light & Insulating

Spun from molten glass at > 1300 °C, glass wool fibre offers excellent thermal insulation at lower density than rockwool. Class A2 fire rating with low thermal conductivity ~0.035 W/m·K.

Particularly suited to office buildings, conference halls, exhibition centres and other roofs where panel weight reduction is desirable while keeping fire safety strong.

dB

PU Side Seal & Edge Protection

GWR panels feature an integrated polyurethane side seal that closes the cut-edge of the glass wool core, preventing fibre release, water ingress and edge crushing during install — a key advantage over plain mineral wool panels.

Two stock profiles available — single-step trapezoid and double-step low profile — selected by aesthetics or required deflection.

Roofs where weight savings matter as much as thermal performance

01 Office & Commercial Buildings

Common choice for office complexes, exhibition halls and conference centres where light weight + good acoustic dampening matter.

02 Sports & Cultural Venues

Stadiums, gymnasiums, theatre and concert venues benefit from glass wool's superior sound absorption.

03 Cold-storage & Logistics Hubs

PU side-seal closes thermal bridges at panel joints — ideal where vapour control and energy efficiency matter.

04 Educational & Public Institutions

Schools, hospitals and government buildings where moderate fire-rating + lightweight roofs simplify retrofits.
