What makes a Groke Entry Door different?

All Groke Doors are designed around three basic criteria; Style, Efficiency, and Security.

Every step in the manufacturing process strives to reach the highest possible level for each of these.  Groke uses the latest CMC technology to create our computer generated styling and true German craftsmanship to assemble a product that meets our highest quality controls.

This is what separates Groke from every other door:

Style:
  • Styling that captures the contemporary, modern, or mid-century modern look.
  • Over 65 unique model designs. 
  • True Custom looks with Groke.  If you provide a drawing of a design it is possible that our manufacturing process can create the look you want to achieve.
  • Our powder coat paint system provides over 200 custom RAL colors plus 12 Decoral wood look stain finishes.
  • All doors can be manufactured to custom sizes to fit almost any application. Single doors widths up to 4 ft. and heights over 10 ft. Our double door systems can provide for a clear opening of to 8 ft. wide.

Energy Efficiency:
  • All doors are designed to meet all European Energy Standards.  These standards far exceed our North American standards.  All our products use the U-Factor rating system.  
  • All full glass models have a .257 U-Factor Rating.
  • All solid door models (no widows) range from a .22 U-Factor (34mm) to a .13 U-Factor (94mm).
  • All doors have multiple seal levels that create a continuous thermal break around the complete unit, including the threshold. Because of this design the Groke product meets European air leakage Class 4 (the highest class).

Security:
  • All doors come standard with three-bolt hook locking.  Other multi-point locking options are available such as bio-metric fingerprint scanners, motorized strikes to function with a home security system, etc.
  • All doors have a top and bottom bolt lock on the hinge side to prevent the door panel from being levered out in the event of a break-in.
  • All doors have heavy duty European type hinges having a load bearing force up to 350 lbs. per hinge.
  • Multi- chambered aluminum profiles with wall thicknesses up to 3mm provide a structural framework with unmatched rigidity and strength.
