Vacuum Glazing

IGCC Certified Vacuum Glazing

IGCC certified vacuum glazing has become a popular option for homebuilders and remodelers, thanks to the growing market for energy-efficient windows. Specifically, the IGCC has established standards for the performance of exterior windows, curtain walls, doors, and storm shutters impacted by windborne debris in hurricanes. By requiring that products meet these criteria, IGCC certified vacuum glazing products reduce the risks of damage to building structures.

Storm Shutters Impacted By Windborne Debris In Hurricanes

Whether you are comparing ASTM C162 vs ASTM C1036 vs ASTM C1048 vs ASTM E1996 or comparing other standards, one thing you should always be aware of is that each of these standards has its own unique requirements. Those requirements may differ from one manufacturer to the next. However, there are some general guidelines that will help you compare the different performance standards.

The first step is to check out the product data. This includes the manufacturer’s qualification data, construction details, finishes, and material descriptions. This should be in the form of a product schedule. Secondly, you should take a look at the drawings. They should include detailed drawings of the window, curtain wall, and storm shutter. In addition, they should include information about the fasteners, including the manufacturer’s recommended slip sheet type. In addition, they should show operational clearances and the installation of flashing.

ASTM E2188 – Standard Test Method For Testing Resistance To Fogg

IGCC certified vacuum glazing is designed for use in weathertight construction. It is also resistant to fog, which is caused by moisture in the air. Several tests are conducted to determine if these products perform according to their specifications. These tests include wind action, project loads, glazing materials deterioration, and other defects.

To meet these requirements, windows must be installed correctly. They must also pass cyclic-pressure and glazed window tests. They must be securely anchored to a structural support. They must also be installed according to the manufacturer’s written instructions. They must be sized properly and installed without distortion. They must be able to withstand structural failures such as excessive deflection and water leakage.

IGCC Certified Products Directory

Despite the name, the Insulating Glass Certification Council is not actually a glass manufacturer. It’s a test and inspection facility that certifies building products for commercial and residential use. It’s located in Mississauga, Ontario, Canada. In addition to its prestigious credentials, the council maintains a spiffy products directory and a nifty website.

Considering the organization’s name, it’s no surprise that it’s been around for a while. The IGCC is also at the forefront of the industry’s drive towards sustainability, having recently introduced a new benchmark to its prestigious roster. The IGCC is no longer limited to commercial and institutional buildings, having added a slew of residential standards to its lexicon.


Firstly, what is a vacuum insulated glass and why would you want it in your home? Second, you can use it to improve energy efficiency, create an indoor/outdoor living space, and reduce carbon emissions, among others. Lastly, it is a lot cheaper than double glazing, making it a viable option for any home improvement project.

In addition, there are many companies manufacturing a variety of vacuum insulated glass. A few notable names include Vitro Glass, Panasonic, Fineo, and Landvac. They all have a vested interest in the industry, and some even sit on the board of directors of the National Glass Association.

Vitro Glass

IGCC certified vacuum double glazing products are made by Vitro Architectural Glass. Vitro is a member of the International Commission on Glass and Fenestration Canada. It has four residential glass fabrication plants in Canada. It also has representatives on the Insulating Glass Certification Council and the Safety Glazing Certification Council.

Vitro is the largest producer of float glass in the Americas. Its Fresno plant holds ENERGY STAR(r) Plants Certification. It also has Cradle to Cradle Bronze certified glass products. It is the gold sponsor of the National Fenestration Rating Council. It has been a Corporate Associate of the Facade Tectonics Institute since 2019. It has a representative on the ILFI Products Hub advisory board.

IGCC Task Group

IGMA’s Technical Services Committee has recently established a new task group to develop guidelines for glazing guidelines. The group will focus on addressing glazing materials and their compatibility. The first draft of the document is expected to be available by the end of the year.

Several IGMA members have participated in the task group. They have developed the first draft of the revised document. This will include a section on ceramic frit. The draft will also contain commentary on each section’s objectives. The task group will review and revise the document. It will then issue a committee ballot. If a positive vote is received, a standard will be published. If a negative vote is received, a reballot will be issued.


So, IGCC certified vacuum glazing is a thin glass that helps to reduce energy costs, while providing a comfortable environment. It can be installed without changing the original window frame. It is made of eight millimeters of thickness and has a thermal conductivity of only 1/4 of that of double glazing.
