Fire rated stairs cover door features:

White sheet metal clad all sides, 7/8" Grenamat(R) board core (mineral based product), all seams overlap are riveted, 1.5" polystyrene foam panel on the top of the cover door, White MDF panel on the top of insulation, * 1 hour fire rating available

The primary function of these products is to stop fire. The fire rated cover doors are quite heavy and require some effort to open and close. Unless your project specifically requires fire rating and especially if the stairs may be used frequently, we would recommend the fire resistant models ( 4085 to 4086) or aluminum folding stairs ( models 3005 to 3015) instead. They use the same ladders and are easier to operate.

Important: read FAQ (common questions) before purchase
