Top 10 Best Insulated File Safes
for June 2023

If you're in the market for a safe to store important documents, files, and records, then an insulated file safe may be just what you need. These safes keep the contents inside safe and secure from heat, cold, and humidity, which makes them ideal for keeping important documents and files safe, even in a climate-controlled office.

Our testing Lab evaluates safes for strength, security, and protection. We evaluate safes for security by testing the locks and bolts, and for strength by testing the safe's weight capacity, as well as the strength of the door's hinges and door panel. We also evaluate safes for protection against heat, cold, and humidity by testing the insulation of the safes, as well as how well the door seals.

We've tested dozens of safes over the years, and these 10 are rated the best insulated file safes of 2022:

What We like

These four-drawer fireproof file cabinets are a great bargain, but our testers didn't care for the look and feel. The deep drawers are nice for files, but the shallow ones put them at a disadvantage. A locking feature would help, too.

This fireproof file cabinet is well made and stores enough documents in a home. The all-steel construction is durable, but it doesn't feel high-end and the wood looks a little cheap and chintzy.

We like the fireproof aspect of it, but I'm disappointed that there's no soft-sided cover. Also, the price tag might be a little steep.

Phoenix Lateral 31 inch 3-Drawer Fireproof File Cabinet with Lock, Water Seal, Gray

PHOENIX SAFE INTERNATIONAL LLC Phoenix Lateral 31 inch 3-Drawer Fireproof File Cabinet with Lock

by PHOENIX SAFE INTERNATIONAL LLC
What We like

The Phoenix Lateral file cabinet is one of the toughest fireproof file cabinets on the market. When it first struck our testing laboratory, some testers were a little leery of the heavy weight. But once they flipped the cabinet on its side, they were amazed by the sturdiness of the cabinet, and the smooth gliding drawers.
