EF Block™ Cost Effective Ease of use, reduces costs Saves energy costs Reduced maintenance costs EF Block is a cost effective building system that is easy to use during construction Delivers a 40% savings in energy costs in the finished structure and has virtually no required maintenance.

EF Block™ Cost Effective Ease of use, reduces construction costs: No special equipment No special labor skills No furring out No insulation Some of the ways initial construction costs are reduced… Skilled masons can be used, but inmate labor can be trained in the morning and have complete walls built by midday. ACI and EF Block will work with your contractor to provide this training and labor on site.

EF Block™ Cost Effective Ease of use, reduces construction costs. Per square foot: Concrete Block: $11.50 EF Block: $8.50 Concrete Block requires furring out plus insulation which costs about $11.50 per square foot when added to the cost of the block compared to just $8.50 for EF Block For a project like the Bakery extension, that could mean thousands of dollars in savings, just on materials costs!

EF Block™ Cost Effective Saves energy costs thermal insulation rating: R-value: 23.16 Dynamic R-Value: 40+ 40% reduction in heating/cooling loss After construction, the savings with EF Block continue because it has a thermal insulation rating R-value of 23.16 and dynamic R-value of 40+, which translates to a 40% improvement in heating/cooling loss, energy costs are substantially reduced day-after-day year-after-year

EF Block™ Cost Effective Reduced maintenance costs: No wood rot No stucco cracking No termite nesting or damage No mold or mildew There is virtually no required maintenance with the EF Block system.

EF Block™ Overview Perfect weight-to-volume ratio Incredibly lightweight Expanded fully molded block Increased durability Easily make on-site modifications To quickly review, EF Block has a Perfect weight to volume ratio that makes the finished structure more stable It's incredibly lightweight – five foot block can be handled by one person, reducing the need for materials moving equipment and reducing the incidents of injuries from strains and breaks associated with traditional concrete blocks It's an expanded (patent pending) fully molded block It is durable – resistant to wind, earthquakes, etc. It's flexible, making it easy to implement on-site modifications.

EF Block™ Benefits Design, Construction & Efficiency Strength & Durability Energy Efficiency Minimal Maintenance To summarize, there are many benefits to using the EF Block system: Design, Construction & Efficiency: During construction, EF Blocks are dry stacked on top of each other without the need for mortared seams. The panels are easy to cut and shape to fit nearly any design. As the blocks are stacked, steel rods (rebar) are inserted in gridwork fashion throughout the cores, and then the cores are filled with concrete. Curved walls, dimensional walls rounded corners, leaning walls and arched openings are now easy and economical. On-site changes can be carried out with a snap. Strength & Durability: EF Block’s structures are 700% stronger then 2’ x 6’ wood framed structures. Walls are designed to stand up to the challenges of severe climates including tornados, fires, hurricanes and earthquakes. Energy Efficiency: EF Block buildings show on average a 40% improvement in heating loss. EF Block buildings have a tighter building envelope and a higher insulating value, leading to fewer drafts and a decrease in operating costs to maintain a comfortable interior environment. HVAC units turn on/off less often. Maintenance: EF Block buildings are dimensionally stable, offering lower maintenance costs. With no wood to rot, no insects, paint lasts longer and stucco cracks are practically eliminated. Reduced maintenance costs contribute to a lower cost-of-ownership.
