Thermally Efficient

Th Omni Block System 8 has a calculated R-20.2 (U=0.049) rating per qualified independent third-party thermal analysis at 105 lb density. Most HVAC engineers and energy specialists agree that there is more to wall energy efficiency than just the R-value of a heavy-weight material. Exposed thermal mass, thermal lag and air-tightness of concrete block walls increase the “performance value” that is routinely used or inputed into computer programs, such as ResCheck or ComCheck. The increased R-24.6 for Omni Block was derived from an ASHRAE calculation method of 90.1 and has been used for years without exception, including Certainteed’s Environments For Living guaranteed utility program.

Independent analysis of Omni Block’s reduced thermal bridging, off-set cross webs, and middle lineal wall configuration combined with two layers of continuous insulation allowing for the voids in the insulation where the cross webs occur was completed. The results were consistent with building performance and actual building energy utility costs.

Insulation Inserts

• Uniformly molded Expanded Polystyrene
• R-4 per inch at 1 lb. density
• Recyclable
• Non-toxic
• CFC free
• No “out gassing”
• No Formaldehyde
• Fluted for moisture migration
• Strategically notched so that when inserted into a block course there is no interference with mortar

8″ Block Design

• 7 5/8″ x 7 5/8″ x 15 5/8″ standard cementitious masonry unit (CMU)
• No direct cross webs
• Thermal path extended to 14″
• Offset and constricted cross webs and a middle lineal wall create cells
• Cells are individually filled with uniformly molded Expanded Polystyrene insulation inserts
• Small cell may be required to be filled with rebar and grout

12″ Block Design

• 11 5/8″ x 7 5/8″ x 15 5/8″ standard cementitious masonry unit (CMU)
• No direct cross webs
• Thermal path extended to 24″
• Offset and constricted cross webs and a middle lineal wall create cells
• Cells are individually filled with uniformly molded EPS insulation
• Small cells may be required to be filled with rebar and grout
• Four layers of thermal mass and three layers of insulation
