Blast- & Gas-Resistant Safe Room Door

A Blast- & Gas-Resistant Safe Room Door is a critical protective barrier designed for civil defense shelters, Israeli Mamad safe rooms, bunkers, and high-security facilities where both explosive protection and airtight sealing are essential. These doors combine armored steel construction, gas-tight gasketing, and multi-point locking systems to safeguard occupants from blast waves, shrapnel, ballistic threats, and CBRN (Chemical, Biological, Radiological, Nuclear) hazards.

🔒 Key Features

1. Blast Resistance

• Built from heavy-gauge steel plate (typically 1″ or more).

• Engineered to withstand explosive overpressure and fragmentation impact.

• Frame is anchored into reinforced concrete walls for maximum integrity.

2. Gas-Tight Sealing

• Equipped with full-perimeter rubber gaskets (EPDM or butyl).

• Ensures airtight closure, blocking harmful gases and contaminants.

• Works in conjunction with NBC/CBRN filtration systems to maintain breathable air.

3. Ballistic Protection (Optional Upgrade)
