What to Know When Buying High-Volume Glass
by Paul Bieber
When buying glass from a fabricator or float manufacturer there are two broad categories to consider: high-volume and low-volume. High-volume is loosely defined as one size of one type of glass exceeding 4,000 pounds. This translates roughly to:
Ordering low-volume from a fabricator is the more expensive way to buy glass. High-volume tempered or laminated glass generally costs 30 percent less than low volume. The advantage of low-volume ordering, though, is speed of delivery. High-volume glass can take three to six weeks getting through the floater and fabricator.
In the Details
Earning a high-volume discount on insulating glass is trickier. When you have a tint over a low-E you need the high-volume size for both lites. If it is tempered over low-E laminated, you have the outboard tempered lite and two lites on the inboard laminated, the low-E and the clear. The money saved by having one lite of high-volume and one lite low-volume is insignificant because the handling is more complicated.
Ordering high-volume glass will usually offer some delivery savings as well. High-volume can often be cased less expensively than low volume. Also, you may want your vendor to label the case, but not each individual lite. They may have to label them for their production control programs, but ask if they can skip this for high-volume work. Your savings will come from easier clean up at the job site.
There is a large amount of savings created by managing the boxing and delivery schedules. We’ll cover that in the next Buyer’s Block. Any questions? Just visit the USGlass News Forum at www.usglassmag.com/phpBB2, enter your questions, and our experts will get you the answers.
