How Much Glass Do I Need?
For My Fireplace and Fire Pit

The amount of glass for each fireplace varies depending on size and fill depth. Full size fireplaces within a typical home may have a 36" wide front, 24" wide rear dimension and 16” deep (from front to back) by a 3" fill level which requires about 64 pounds of glass. We find that average size fireplaces (30" X 16" deep x 3") typicaly require 74 pounds. Any excess glass ordered can be returned for full refund and credit anytime within 30 days.

For Fireplaces:
3" Fill Depth Recomended or 2" Depth With Lava Rock Filler

Example 30" x 16" x 3" = 1440, 1440 divided by 231 = 6.23, 6.23 x 12 = 75 lbs (3" of glass)

Example 30" x 16" x 4" = 1920, 1440 divided by 231 = 8.31, 8.31 x 12 = 99 lbs (4" of glass)

The 30 is derived by the average from the front and the back. (36”(front) + 24”(back)= 60”, 60/2 = 30”

There are 231 cubic inches of glass per 12 pounds.

The glass is delivered in 5 gallon buckets at 60 lbs. per bucket and that equals 12 lbs per gallon.
