Steel-Craft’s Therm-O-Dor overhead doors are manufactured from top-quality, Canadian-made steel, and are designed from the inside out to ensure maximum strength. Our doors feature a patented mechanical interlock design and heavy-duty hardware. Together, these features offer industry-leading durability and excellent protection against break-ins. All Therm-O-Dor overhead doors are corrosion-resistant and feature treatments of a zinc base coating and two polyester topcoats. The exteriors are paintable, won’t fade, and are easy to clean.

The Flexible top seal keeps cold and debris out, and the section weather seals keep wind and cold out. The PVC retainer aids in door rigidity, and top-quality Canadian galvanized steel is durable and rust resistant – just like the two-coat exterior polyester paint finish on the inner and outer skin. The Therm-O-Break design reduces cold/heat/moisture conductivity.

Mechanically interlocked front and back skins increase strength, and continuous steel overlap secures hardware attachments. The flexible floor seal conforms to minor irregularities to keep out cold and debris, while insulated windows feature sealed lites and high-impact polymer frames.

Heavy-duty rollers and hardware are durable and make for easy installation

The TD 134 model comes with a 1-3/4″ layer of polyurethane insulation, which gives an R-value of 16.04, twice the efficiency of competitors’ polystyrene panels.
