Why Choose Glass Door Hardware?

Glass is the ideal material for doors in many situations. Some benefits of glass include:

  • Allows in natural light, which boosts mood and productivity.

  • Reduces need for artificial lighting.

  • Can be treated to reduce glare, prevent heat absorption, and provide protection from UV light.

  • Increases property value.

  • Maintains a clean, modern aesthetic.

  • Easy to clean.

  • Highly customizable.

  • Glass doesn’t rust or corrode.

  • Glass can easily be recycled.

History of Glass Sliding Doors

The sliding glass doors we know today originated during the pre-war era during the start of the 20th century, and were developed heavily until the start of World War II.  Some historians speculate that these doors were designed after a Japanese door called Shoji, a sliding door that hangs from a wooden frame and is covered with tough translucent paper. 

Over time, glass replaced less stable materials to ensure durability. After the World War II era, new builders and manufacturers wanted to create a seamless space between landscape and home, which led to an influx of sliding glass doors in homes and commercial buildings. 

Residential vs. Commercial Glass Hardware

Although you cannot see any visible difference between residential and commercial glass, there are many subtle factors that differentiate them from each other. 

Residential glass is much lighter and easier to install than commercial glass, and is also easier to replace. This type of glass is thinner and requires less glazing on windows and doors. There is more focus on overall aesthetics in residential spaces, and residential glass sometimes has patterns, textures, and even tints, while commercial glass usually seeks to let in as much light as possible. 

Common Types of Residential Glass

  • Obscured Glass: Any type of glass which allows light to come in, but can’t be clearly seen through (i.e. tinted or acid etched). These types of glass are designed to increase privacy in a residential space.

  • Annealed Glass: Cooled in a slow and controlled process to reduce stress and increase strength, annealed glass is float glass that has not been heat-treated. If it breaks, it can break into dangerous, sharp pieces.

  • Tempered Glass: Float glass which has been heat-treated to create a glass that is 4 times stronger than annealed glass. If tempered glass breaks, it breaks into tiny, dull pieces, making it a type of safety glass.

Commercial glass is heavier, stronger, and typically at least ¼” thicker than residential glass. Commercial glass is larger and more durable than residential glass, and requires more material and multiple glass panes. 

Commercial spaces require a different glazing technique due to their size and scale, which makes the installation process more complicated. It also costs more to install because specialized equipment is often required to set commercial glass. Commercial glass is designed for higher thermal performance, and to allow more light into the interior spaces. 

Common Types of Commercial Glass

  • Plexiglass: Shatter-resistant glass widely used in the construction of skylights, aquariums, building windows, displays, and security barriers.

  • Laminated Glass: Made up of two or more glass panels with a plastic film between them, which offers more protection against extreme weather and vandalism.

  • Insulated Glass: Glass panes are separated by a vacuum space, which is filled with an inert gas to ensure high energy efficiency.

  • Tempered Glass: Float glass which has been heat-treated to create a glass that is 4 times stronger than annealed glass. If tempered glass breaks, it breaks into tiny, dull pieces, making it a type of safety glass.

Sustainability of Glass Door Hardware 

ASSA ABLOY’S core values include vision, realism, courage, and ethics, and we strive to keep sustainability at the forefront of our business model. Glass doors allow for daylighting, which is the process of bringing natural light and direct sunlight into a building through the interior glass. 

Daylighting reduces the need for artificial lighting, reducing the cost of energy consumption. Increasing the natural light in a workspace can also have a positive impact on the workers’ mood and productivity. 

Glass is also one of the most durable door solutions, as it never has to be painted or touched up. Glass helps create a modern atmosphere that never goes out of style, which means you won’t need to replace it when interior decorating styles change. 

How to Determine Glass Thickness and Door Size

Choosing the correct glass thickness for your door is important, because if the glass is too thin, small fluctuations of interior air pressure can cause the glass to tremble or shimmer. As the unsupported span or height of the glass panels increases, the glass thickness must also increase to maintain a reasonable stiffness. ASSA ABLOY Glass Solutions part numbers include a letter which identifies glass thickness or range of thickness compatible with that item. For example, part numbers containing "AC" can be used on glass thicknesses ranging from 3/8" to 9 /16".

Door Handing / Swing

The handing of a door refers to the direction that the door swings. To determine the handing of your door, you will need to determine if the door opens by pushing away from you or pulling towards you, and which side the hinges/pivots are on as you are viewing the door. 

  • If the hinges/pivots are on your Left side, and the door is pushing away from you, it is a Left Hand (LH) #6 Swing.

  • If the hinges/pivots are on your Right side, and the door is pushing away from you it is a Right Hand (RH) #5 Swing.

  • If the  hinges/pivots are on your Left side and the door is pulling towards you, it is a Left Hand Reverse (LHR) #4 Swing.

  • If the  hinges/pivots are on your Right side and the door is pulling towards you, it is a Right hand Reverse (RHR) #3 Swing.

Glass Door Styles

There are five basic configurations of glass doors as established by the Glass Association of North America (GANA). For the available variations of each style, refer to the Glass Door Configuration sheets.

  1. Full door rail top and bottom

  2. Full door rail bottom and patch fitting top

  3. Patch fitting top and bottom

  4. Patch fitting top and bottom with patch lock

  5. Hinges

Sidelite Glazing Material Options

Sidelites are glazed into channels, rails or header pockets. Determining the best sidelite material depends on your desired aesthetic and the amount of money you are willing to spend. Some people choose to use rails if the door has rails so there is a continuous sight line of metal, while others use u-channels when they want less metal showing. U-channels with rail doors are also a more affordable option. 


U-Channels

U-channels secure glass into position and create a continuous, minimal profile that allows the maximum amount of natural light to enter the space. U-channels are designed to preserve the clean, modern appearance of glass walls and sidelites.

Pivots

Pivot sets provide the best possible means of hanging a door. Pivots are needed to compliment opposing doors. Doors using overhead closers will need a floor pivot, while doors using floor closers will need a top pivot. Most top pivots will require a header in which to mortise them. And bottom pivots are provided with a floor plate to anchor them to the floor. ASSA ABLOY provides a variety of pivots which are designed to work with the laws of physics to provide long-lasting performance and reliability. 

What Type of Pivot is Needed for Glass Doors? 

The type of pivot needed for your glass door is determined by the hardware being used, such as patches or rails. There are options based on weight for end load floor pivots, which are the best option for doors with bottom rails. The PV-FM-300END Endload Pivot is the industry's first and only 300 lb end load bottom pivot, which exceeds other end load pivots which only carry a 200 lb weight limit.  

Walking beam top pivots are available in heavy duty versions for doors weighing over 350lbs, as well as extended pin versions for doors over 108” tall. Surface mounted top pivots are also available for patches when no header is desired. 

Top and bottom required door clearances will vary depending upon the type of pivot being used.
