3/8” Comb Light FR™ - Class A Fire-Rated Lightweight Panels

3/8” Comb Light FR is an advanced, lightweight panel designed specifically for commercial and institutional environments requiring strict fire safety compliance and robust strength.

Engineered with a fire-rated 3/8″ cellular honeycomb core bonded to fire-rated 3mm HDF/MDF facings, Comb Light FR achieves maximum structural stability and impact resistance while significantly reducing overall panel mass.

Tested to ASTM E-84 standards to earn a Class A Fire Rating, this versatile material is an ideal solution for oversized architectural elements, floating shelves, wall panels, doors, and commercial casegoods.

Class A Fire Rating (ASTM E-84 Tested).
Easily apply face materials (veneer, laminate, and coatings).
Finish with a variety of edge options.
Rigid face material supports selected methods of attachment.
Optional skin thicknesses are available.
