The Groke Modern Entry Doors will be on display at the International Door Association (IDA) Expo April 29th and 30th at the Las Vegas Convention Center. You can visit the SOMMER booth #223 to see why Design, Security, and Energy Performance are synonymous with Groke Door. 

Groke uses aluminum to build their modern entry doors.
​
​Why Aluminum? Because it is so much more than just cans and foil.

Today aluminum is one of the most popular materials in use. Aluminum’s unique properties are the key to its versatility. 

• ​Weight: Aluminum is 1/3 lighter than steel. 
• Strength: The fact that it is lighter than steel does not affect its strength. Most all aluminum used today is an aluminum alloy, meaning it is a mixture of different materials.  This allows manufacturers the ability to create materials with a wide range of tensile strengths.  Unlike most grades of steel, aluminum does not become brittle at low temperatures. This is one of the reasons why aluminum is used in construction in the aerospace industry.
• Formability: Because aluminum is softer than steel it can be formed and shaped many different ways.  Its superior malleability, either hot or cold, makes it a perfect material for extrusion.  Rolling, bending, forming, and cutting with less wear on the machinery make aluminum an ideal material for designing. This basic ability to form the material to adjust to the design in lieu of the design adjusting to the material be used have more and more industries moving toward aluminum as we see in the auto industry.
• Corrosion Resistance: Aluminum reacts with the oxygen in the air to form an extremely thin layer of oxide.  This layer is thin but very dense and provides excellent corrosion protection.  This oxide layer is also self-repairing if damaged.  Aluminum does not rust like steel or iron. This oxidation is corrosion but it only formed to self-protect, a natural effect.
• Recyclable and Sustainability: Aluminum is a material that is easily recycled. Manufacturing from recycled aluminum uses approximately 5% of the energy required to create aluminum from bauxite, the raw form of aluminum. And this material can be recycled over and over again. Nearly 75% of all aluminum ever produced is still in use today.

These unique properties of aluminum help make it the material of choice for industries such as transportation, aerospace, and building materials. And this list will continue to grow.

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.
  

Conference and Exhibition | May 29-31

Groke Door is going to be at the Dwell on Design Show in LA. Come and check out our modern entry doors at our booth #2235.  
A three-day exhibition and conference, comprised of one trade day and two consumer days, at the Los Angeles Convention Center featuring world-class speakers, product demonstrations, continuing education classes for design professionals, and seminars for design-seeking consumers. Each year, Dwell editors carefully craft a program that invites you to “step into the pages of Dwell” and experience modern design.

You hear the terms U-Factor and R-Value a lot but do you really know what it means? Both are measures of energy performance but are reached in very different ways.  Most of us know that the higher the R-Value the better the insulation and therefore the better the energy savings for our homes.  We also understand that if the R-Value is high then the U-Value or U-Factor is low.  In order to understand how these ratings can help us make wish decisions about investing in energy savings we must clearly understand what the ratings mean.

R-Value is a measure of resistance to heat flow.  Generally, R-Value is given for a certain thickness of specific material, such as fiberglass wall insulation.  The R-Value of a structure can be estimated by simply adding up the R-Value of each material that makes up the layers in the wall (exterior sheathing, insulation, interior drywall, etc.).

One of the many wonderful things about Groke custom aluminum doors is the fact that they are all truly custom made for your home or building application so your door is the perfect fit and specification.  Many of our customers love the fact that we can build very wide entry doors… up to 45.5 inches wide usable opening width for single doors(51 inches wide to the outside edges of the jamb).  

Depending on architectural constraints, having the ability to specify your rough opening width is a great opportunity to go wide!  There are many benefits to having a wide door such as increased accessibility for wheelchairs or baby strollers, greater convenience when moving furniture in or out, or simply to make an impressive visual or aesthetic impression.  Having a wide, beautiful custom door is easy with Groke!

“Custom” is a word you will hear a lot when looking for doors and the term can mean a few different things.  In reality, there are different levels of customization available from different manufacturers, and some doors are certainly more custom than others.  Often times, the need for a custom door is driven by the fact that the application requires an unusual size.

Let’s explore the sizing issue a little deeper.
