Greenblock Physical & Technical
Characteristics

5. Sound Transmission (STC) 55+

6. Capillarity of EPS: None

7. Minimum Pouring Temperatures: to minus 4º F or minus 20º C

8. Production Method: Shape molding of Flame Retardant Expandable Polystyrene (EPS) by heat and steam with no additives using only raw EPS bead bearing National Evaluation Report (NER # 236.238.384 or 479) Certifications as required by all North American building code authorities.

9. Fire Resistance:

• A fire retardant is added to Greenblock EPS during manufacturing
• Greenblock 6, 8, 10, & 12 inch concrete core provides a fire resistance of four (4) hours in accordance with ASTM E 119 and CAN/ULCS 101.
• Greenblock 4 inch concrete core provides a fire resistance of two (2) hours in accordance with ASTM E 119 and CAN/ULCS 101.
• Meets flame spread (10), max acceptance 75 and smoke development (less than 300), max. acceptance 450, as required by UL723, UBC8-11, ASTM E84. (UL Report R 4775)

Expanded Polystyrene has a flash ignition temperature of 340º C (655º F), where pine is 224º C (400 º F). (Data from National Research Council of Canada) Self-ignition is 425º C (797º F).

10. Building Method: Stack units as if CMUs. Secure straight and plumb with alignment hardware, fill with #5 or #6 slump, 2500 psi concrete leaving units in place providing insulation, surface finish strapping & air/vapor barrier (resulting from EPS units filled solidly with concrete without any penetrations therein).

11. Pour Height 4’-10’ monolithic pours, no seams or joints.

12. R-Value (Thermal Resistance) in accordance w/ ASHRAE 2001Fundamentals Handbook & ASTM C177, 6” & 8” Core EPS R 23/4 inch core EPS R 18. The Thermal Performance of an assembled wall including calculations for EPS, Thermal Bridging, Thermal Mass & Air Tightness will be higher  depending upon type and size of doors/windows, ceiling heights, attic insulation etc.

13. Water Vapor Test based on test result of 138.0 ng/Pa•s•m2 (200ng/ Pa•s•.m2, max.)

14. Water Absorption Test Result .35% by Volume.

15. Meets requirements for “Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation”, as a Type II Thermal Insulating Material per ASTM C578.

16. Code Compliance – ICC ESR 1479: The ICC ES Report documents compliance to the 2006 International Building Code (IBC), the 2006 International Residential Code (IRC) the International One and Two Family Dwelling Code and the 2007 Florida Building Codes for Residential and Building including use in High Velocity Hurricane Zones(HVHZ).

17. Polypropylene Reinforcing webs meet requirements for plastic materials when tested in accordance with ASTM D 1929, UBC 26, ASTMD635, ASTMD2843.

18. Fastener withdrawal resistance in accordance with ASTM D 1761 and fastener lateral resistance testing.

Finish Requirements:

• EPS Compatible, Damp proofing/waterproofing as required by local code.
• Exterior surface shall be covered with approved finish materials. (i.e., Brick, Stucco, Siding, Etc.)

20. Wind Speed rating: by P.E. design per ACI 318 and ACI 347 as required for specified use and as required by local code.

21. Seismic Rating: by P.E. design per ACI 318 and ACI 347 as required for specified use and as required by local code.

	NOTE: Construction of a GREENBLOCK built structure may require P.E. stamp structural drawings & determination of air exchange requirements/equipment. It is recommended consulting your local building official.
