The new product guide from Cardinal Glass Industries, which supplies the glass for Western Window Systems’ custom products, is now available for dealers in Western Window Systems’ custom channel.
The full-color, 58-page product guide supplies dealers with all the key information necessary to make informed purchasing decisions, including data regarding U-values, light-to-solar gain, and solar heat gain coefficient, as well as the types of coating available and when and where to use argon-filled glass.
“The new Cardinal product guide is filled with great technical information, and dealers will find it very useful,” says Cameron Wyatt, Western Window Systems’ vice president of design and supply chain. “The great thing about Cardinal is that it is an end-to-end supplier, so they control the process from the beginning through to the final IG seal. Other glass suppliers simply sell their product to manufacturers, so some of the warranty, quality, and performance specifications are from third parties. Not so with Cardinal.”
And in regard to using products in high altitudes, Cardinal IG altitude limit charts provide information to help dealers determine when capillary tubes are required, based on project elevation and window size.
The product guide, in the form of a PDF, can also aid in determining the maximum elevation at which a unit may be installed before it requires a capillary tube. The limits are based on deflections the units will encounter, based on their point of origin in Phoenix.
The product guide PDF is organized by IG composition — and it’s easy to use: First, determine the glass thickness and spacer combination. Next, determine whether the unit is a square or a rectangle. If the longest side of the IG is twice as long or longer than the shortest side, the 2.0 table is used. In other cases, the 1.0 values are used.
Then, the dealer determines the dimension of the short side, as well as the altitude limit for annealed and tempered units. For example, per the chart, a dual-pane tempered unit with 4.7mm glass and a 14.5mm spacer (a common unit in Western Window Systems multi-slide doors) and dimensions of 96 inches tall by 36 inches wide (the 2.0 table applies in this case) does not need capillary tubes unless the unit is installed at an elevation over 10,000.
“Many times, even in higher elevations than most people would expect,” Wyatt says, “you don’t need to use capillary tubes, and you can maintain the U-value performance of argon for your projects.”
The new guide also provides an overview of glass concepts and terminology. Though the main focus is on residential applications, much of the information can be used to gain better understanding of glass performance in all types of buildings. So, it can help architects, designers, dealers make more informed decisions.
