GREENSTAR BLOX™ is an energy efficient and environmentally friendly building block comprised of recycled short-fiber cellulose, portland cement, water, and an organic curing agent ad-mixture.
"We don't just use any paper. We prefer a special blend of recycled newspapers, lottery tickets, office documents, and phone books for all of our products, during both manufacturing of and construction with our GREENSTAR BLOX™. We have replaced aggregates normally found in concrete with our gradations of cellulose fibers to form a material with high insulating and structural characteristics." - Zach Rabon
The advantages of using GREENSTAR BLOX™ are numerous. The simplicity of masonry construction is only topped with the use of light weight materials.
GREENSTAR BLOX™ products come in two sizes: a solid core CMU or Cinder block shape (8" x 8" x 16") weighing 17 lbs each and an Adobe shape (10" x 14" x 4") weighing only 8 pounds.
GREENSTAR BLOX™ will double and even triple the R-values of conventional wood frame construction.
Made from 65% recycled cellulose |
Contributes to LEED Certification |
No EPS, polystyrene or oil products |
This removes the possible off-gassing from competing oil based "Green" products when exposed to heat or sun |
Standard Masonry Construction |
Every mason knows how to build with this product |
Twice the strength of cinder |
Designed to hurricane strength and building standards |
One third the weight of |
Easily shipped anywhere in the world |
R25 Insulation values |
Does not act as a heat or cold reservoir |
Monolithic Wall System |
GREENSTAR BLOX™ are solid core building concrete masonry units and do not call for vermiculite, or any other fill materials. This results is a solid, uniform material or a monolithic wall yielding greater strength. |
Non-combustible |
Withstands flame from an acetylene torch |
Water, mold resistant |
Floats and has water characteristics equal to a standard cinder block |
Ballistic resistant |
Unlike polystyrene or concrete based sytems, GREENSTAR BLOX™ can absorb blows from a sledge hammers and high powered rifle shots |
Termite/rodent resistant |
|
Acoustic Barrier |
Excellent sound insulation and noise abatement |
Consumer Friendly |
Hang paintings, shelves with standard wood anchors and screws. |
GREENSTAR BLOX™ have a superior compression strength that was tested against other concrete masonry units by Arizona State University. GREENSTAR BLOX™ load bearing psi was found to be 3,000 psi compared to standard 1900 psi for masonry requirements.
Texas Tech University, PSI, Omega Point Laboratories are other facilities conducting tests pertaining to compressive strength, insulation and fire ratings, moisture absorbency, and wind load tolerances.
Mason Greenstar Inc is leading the charge with the International Code Council to set standards for this type of construction material. The American Society for Testing Materials (ASTM) and National Fire Safety Rating Systems (NFRS) both have standards that our GREENSTAR BLOX™ will exceed in present and future testing.
