How do I build a fireproof wall?
The most fire-resistant exterior walls are clad in fire-resistant materials such as stucco, brick or concrete. Walls clad in less fire-resistant materials, such as vinyl or wood siding, should incorporate fire-resistant wallboard, with the siding attached directly to the wallboard on the exterior surface of the wall.
Will drywall burn fire?
Drywall is relatively fire resistant. It’s composed of gypsum pressed between two sheets of thick paper. Gypsum is a soft mineral that by itself is not flammable. Once the water dissipates, the gypsum begins to heat past the boiling point of water, and may begin to burn.
