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.

 

OPTIONAL 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 Consumption to achieve the FRS designation by Underwriters Laboratories. The fire retardant treated plywood used in The Marwin Company, Inc. stairways carries a Class 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 Class 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 Classified with FR-S Rating
