| Weight Classifications |
|
|
Concrete block has three classifications according to weight. Lightweight units weigh less than 105 pounds per cubic foot. Medium Weight units weigh between 105 and less than 125 pounds per cubic foot, while Normal Weight units weigh 125 pounds per cubic foot or more. Betco Supreme manufactures all three weight classifications. Lightweight block is the lightest, has the highest fire rating, the highest R value and will be more effective for sound absorption (NRC rating). Normal Weight block will have a tighter texture and will be more effective for sound transmission (STC rating).
All weight classifications meet or exceed ASTM C90 Standard Specification for
Loadbearing Concrete Masonry Units.
