21" x 31" Fire Rated Crawl Space Access Door DWF - Fakro

21" x 31" DWF-FIRERATED Fire Rated Crawl Space Access Door – Fakro

Accessing crawl spaces and knee wall areas shouldn't mean compromising fire rating or dealing with drafty, poorly sealed openings that waste energy.

Too many property owners and contractors use standard access doors that either fail fire inspections or create ongoing problems with air leaks, moisture intrusion, and heat loss. They may look fine initially, but they will ultimately result in expensive do-overs and unhappy clients.

The 21" x 31" DWF-FIRERATED Fire Rated Crawl Space Access Door from Fakro eliminates these headaches. This fully assembled, fire-rated door delivers EI1/EI2 60-minute fire resistance while providing exceptional thermal insulation and airtight sealing. It offers a reliable solution that meets building codes and energy efficiency standards for non-livable space access.
