Manufacturers of Ferro-Therm - Heavy Gauge Metal Insulation.

Ferro-Therm, recognized by architects, builders and industrial engineers all over the country as the most effective metal insulation, is now made in heavy gauge sheets, up to 10 feet in length. This new heavy gauge Ferro-Therm, has all the advantages of light gauge Ferro-Therm, the same high insulating value, with the reflectivity of 95% of all radiated heat. Yet, for the same gauge and size of sheet, it has all the structural advantages of any any steel sheet. This new heavy gauge Ferro-Therm offers the opportunity of obtaining a 'plus value', efficient insulation, wherever you install steel sheets. Ferro-Therm has the same structural strength, gauge for gauge, as ordinary coated steel, and its alloy coding gives it the same high resistance to corrosion. Ferro-Therm can be installed wherever you can install any steel sheet. And you can fabricate with Ferro-Therm as with ordinary steel, it can be welded, bolted or fabricated to conform to any specification.
