How to fireproof boxes

Updated November 21, 2016

The threat of fire is something that we should prepare for rather than simply hope that it does not happen. Large items can often be easily replaced, but special items such as photos, negatives, stock certificates and even cash should be protected. Making an existing cardboard box fireproof is not possible, but making a fireproof box to hold your valuables in case of fire is. Focus on getting the right items together and you will be able to give yourself some peace of mind.

Cut two pieces of Vermiculite Fire Board with a circulating saw to 13 1/4 inches in length.

Cut four pieces of Vermiculite Fire Board with a circulating saw to 11 3/4 inches in length.

Apply a bead of fireproof adhesive around the edge of one of the 11 3/4-inch pieces of wood and butt it against the 13 3/4-inch piece of wood. Secure the pieces together with 1 1/4-inch wood screws.

Repeat step three for the remaining side pieces to make sure that two of the sides, the top and the bottom of the box are the same length and width.

Apply fireproof adhesive around the edges of the bottom of the box and secure it to the other pieces with 1 1/4-inch wood screws.

Attach the top of the box with two durable hinges placed at both ends of the box top.

Install a latch and catch system to keep the box closed.

Apply a bead of fireproof adhesive along all seams and allow the box to dry completely for 24 hours.

Warning

Always use gloves and safety goggles when working with saws.
