Important Fire Safety Information: When rigid vinyl siding is exposed to significant heat or flame, the vinyl will

soften, sag, melt or burn, and may thereby expose material underneath. Care must be exercised when selecting

underlayment materials because many underlayment materials are made from organic materials that are

combustible. You should ascertain the fire properties of underlayment materials prior to installation. All materials

should be installed in accordance with local, state and federal Building Code and fire regulations.
