Light transmission

70–90% transmittance lets diffuse daylight into the workspace, cutting daytime lighting bills. Translucent (opal) sheets diffuse glare for comfort.

Verified standards we reference

• GB/T 14206-2015 — glass fiber reinforced polyester continuous sheets (flat P / sinusoidal Z / trapezoidal T; translucent & opaque; normal / flame-retardant grades).
• GB 8624-2012 — building product fire classification (A non-combustible / B1 difficult-to-burn / B2 combustible).

Pending verification

ASTM E108 / EN 13501 roof fire clauses and local building codes must be confirmed per project before being quoted. Industry-typical laminate values: tensile 60–120 MPa, flexural 100–180 MPa; our test reports to be filled in.
