FAQ's

Yes. Optima fire-resistant systems offer integrity (E) and integrity-plus-insulation (EI) ratings, tested to EN 1364-1 and BS 476 standards. Ratings range from 30 to 120+ minutes depending on the system specified.

"E" (Integrity) means the system contains flames and smoke for the rated period. "EI" (Integrity + Insulation) additionally limits heat transfer to the non-fire side, allowing safe egress past the partition during a fire.

Yes — many fire-resistant systems dual-certify for acoustic performance. Refer to each system page for the tested Rw rating alongside the fire classification.

Fire-rated partitions must be specified with matching fire-rated doors to maintain compartmentation. Each fire-resistant system page lists compatible certified door sets.

Fire rating is determined by building regulations and the compartmentation strategy for your project. Consult your fire engineer or contact our team to verify the rating required for your specific application.
