R-16 Insulation

Insulation Options
G-5138  Thickness: 1 3/8"  R-12 Insulation
G-5200  Thickness: 2"      R-18 Insulation

Features and Benefits


  •     Stronger and more energy-efficient insulation
  •     Solidly bonded to the steel sheets providing a section that is resistant to flexion.


  •     Optimize insulation and reduce seal failures with galvanized steel spacer technology
  •     Ensure a long lasting and refined appearance with one-piece molded polypropylene window frame.


  •     Sections are strengthened by 2 steel walls joined together with mechanical interlocking joints which are more solid than just two bonded walls.
  •     Mechanical thermal breaks which are more efficient compared to thermal breaks made with glue.
  •     Triple-contact joints provide 2 times more weather tightness than those of the competition.


  •     Provide stronger fastening for hinges and struts. These 14-gauge plates are 2 times thicker than 20-gauge plates used by other manufacturers.


  •     Provide a thermal break that is more effective than steel end caps which form a thermal bridge.
  •     Structural elements of the sections, the kiln-dried pine wood end blocks are installed at the outer ends of the section. They are stronger than insulation covered with a steel cap.


  •     Provides much better fastening of the end hinges. The lag screws engage 8 threads into the wood, compared to a self-tapping screw going through a steel end cap engaging only about 2 or 3 threads.

G-5000 Features

Panel Construction

G-5000 Panel Construction Comercial Garage door1. Steel walls

  • 26/26-gain gauge, G60 hot-dipped galvanized steel with five coats of protective finish.
  •     Baked-on polyester paint. Can be repainted.
  •     Woodgrinish on both sides of the door.
  •     Same quality of corrosion-resistant steel for interior and exterior faces.

2.  Insulated door with high-pressure injected polyurethane foam ensuring a high thermal-resistance rating and the solidity of a composite material

  • G-5000: 1 3⁄4” (44.5 mm), R-16 (RSI 2.8 or k= 0.357 W/m2K)
  • G-5138: 1 3⁄8” (35 mm), R-12 (RSI 2.1 or k=0.476 W/m2K)
  • G-5200: 2” (50 mm), R-18 (RSI 3.2 or k= 0.313 W/m2K)

3. InterLokTM joints between each section:

  • Mechanical joints ensure stronger sections with walls of each panel mechanically interlocked (not only bonded by the polyurethane).
  • Mechanical thermal break avoids heat transfer between the interior and exterior walls of each section.
  • Triple-contact joint prevents air infiltration.

4. U-shaped tubular bottom weatherstripping made of thermoplastic elastomer (TPE) ensures the weather tightness of the threshold. Remains flexible and watertight during cold weather, to -62°F (-52°C).

5. Wood end blocks made of kiln-dried pine (grade 4). With our lag screw system, ensure better fastening of the end hinges. They also provide a thermal break which prevents thermal bridging.

6. 14-gauge steel reinforcement plates placed inside the door for solidly attaching hinges and struts.

Door weight:
