Insulated Rolling Steel Door | by SDI

Save on Heating

Interlocking slat design with solid insulation inserts provide consistent density and complete coverage. Looks great and helps to conserve energy and save on heating.

Prevent Drafts

Lintel brush, vinyl guide and bottom bar seals reduce air infiltration.

Durable Quality

The Durable Structural angle guides and bottom bar stand up to abuse and can be easily repaired unlike roll formed designs. Steel plate brackets are superior to their stamped steel counterparts.
