The Marwin Folding Attic Stairway is designed with the
"Pro" Contractor and quality-oriented dealer in mind.
All wood components are sourced from high-grade
SYP lumber with quality and safety in mind.
O P TIO NAL FIRE RETARDANT TREATMENT:
The upgraded (9mm) plywood used on our Fire
Treated Stairs is treated with D-Blaze fire
retardant which meets the UL standards for the
designation of FRS Rating. This means that the
treatment has met the 30 minute test standards
for Flame Spread, Smoke Developed, & Fuel
C onsumption to achieve the FRS designation by
Underwriters Laboratories. The fire retardant
treated plywood used in The Marwin C ompany,
Inc. stairways carries a C lass I or ‘A’ rating
which is recommended for areas where fire
hazards are most severe. Materials with the
lowest rate of flame spread (0-25) are classed
by all building codes as C lass I or ‘A’.
D-Blaze’s flamespread characteristics have
been tested and approved by the following
applicable standards:
- NFPA Standard No. 255
- ASTM Standard E-84
- UL C lassified with FR-S Rating
