Door Construction

foamed-in-place polyurethane sections

3” thick foamed-in-place polyurethane sections feature continuous steel strips for flexibility in hinge placement.

Joint profile for Insulated Sectional Steel Doors

Patented dual barrier tongue-and-groove joint profile creates a virtually impenetrable path for air leakage in between sections.

Jamb seal for Insulated Sectional Steel Doors

Patented thermal performance jamb seal (optional) combines a longer flapper seal and bulb seal for superior perimeter protection.

Weatherseal for Insulated Sectional Steel Doors

Bottom weatherseal with rigid PVC retainer and dual durometer PCV bulb seal locks out air and water leakage through the bottom section. Optional outer EPDM bulb seal provides additional protection.

thermal break for Insulated Sectional Steel Doors

PVC thermal break on end stiles limits the transfer of temperature.
