Garaga G-1000 Commercial Door

Ideal for large-sized doors

The G-1000 commercial garage door is made of pre-paint aluminum with a thickness of 0.60 mm 1 3/4 in. (44.5 mm). This door is insulated with high-pressure injected polyurethane foam ensuring a high thermal-resistance rating of R-16 (RSI 2.8). Ideal for large-sized doors!

  • Aluminum
  • Thickness: 1 ¾”
  • 4 colors
  • Polyurethane sandwich door
  • R‑16 insulation
  • Models: 4 Grooves and 2 Grooves


Features and benefits

A) High-pressure injected polyurethane

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

B) Aluminum

  • Pre-painted (5 coats), 0.60 mm thick aluminum is ideal for large-sized doors. Being very lightweighthelps to extend the life of the components for doors with a large number of operation cycles.

C) InterlokTM triple-contact joints

  • Sections are strengthened by 2 aluminum walls joined together with mechanical interlocking joints which are more solid than just two bonded walls.
  • Their mechanical thermal breaks are more efficient compared to thermal breaks made with glue.
  • Triple-contact joints provide 2 times more weathertightness than those of the competition. Garaga Lab - Tested Logo

D) Metal reinforcement plates

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

E) Wood end blocks

  • Provide a thermal break that is more effective than steel end caps which form a thermal bridge. Garaga Lab - Tested Logo
  • As 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.

F) Lag screw system

  • 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.

Panel construction

1) Aluminum walls

  • Thickness of 0.023” (0.60 mm).
  • Pre-painted aluminum with five coats of protective finish. Baked-on polyester paint. Can be repainted and is corrosion-resistant.
  • Woodgrain finish on both sides of the door.

2) 1 ¾” (44.5 mm) insulated door with high-pressure injected polyurethane foam ensuring a high thermal-resistance rating of R-16 (RSI 2.8 or k=0.357 W/m2K) and the solidity of a composite material.

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) Flexible top weatherstripping 2 ½” (64 mm) and aluminum extrusion for aluminum doors of 10’ (3048 mm) wide and over.

6) 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.

7) 14-gauge steel reinforcement plates placed inside the door for solidly attaching hinges and struts.
