Fox Blocks Takes Home Nine Awards During World of Concrete

| Insulated Concrete Forms | January 30, 2017

WOC 2017

Fox Blocks received nine top awards for innovation and efficiency at the 2017 International ICF Builder Awards in Las Vegas, NV. Over 300 professionals attended this year’s award ceremony, held in conjunction with the World of Concrete Tradeshow. The executive director of ICF Builder Group and organizer of the competition, Clark Ricks, said, “The variety and scale of projects being built with ICFs is truly astounding. It’s time these outstanding projects received recongnition, and we feel privileged to take a leading role in that. These projects truly represent the best of the best.” Five “Best In Show” awards were given to Fox Blocks for outstanding breakthroughs in the use of ICFs in the following categories: hospitality, light commercial, development, multifamily, and small residential.

Fox Blocks received four, 1st Runner-up awards for major accomplishments advancing the use of ICFs in the heavy commercial, education, multifamily, and large residential categories.

Key factors considered in being chosen for these awards were affordability, energy efficiency, complexity of design, striking architecture, and the challenges the construction team faced and overcame during the build – setting a new standard for the entire ICF industry. Without the cooperation of a wide array of team players, these wins could not be achieved. We thank our dealers, distributors, and installers that contributed to the construction of these outstanding projects, as well as the many developers, architects, engineers, and building owner that have recommended and specified our product. We would also like to thank the organizers of the annual Builder Awards for their continued support and dedication to the ICF industry. Congratulations to all who participated!

Fox Blocks at Federal Asset Management Policy Forum and Expo

| Benefits of ICFs | Building Tips Using ICFs | Fox Blocks ICF Events | Insulated Concrete Forms | October 25, 2016

IMG_6759Fox Blocks Vice President Mike Kennaw and East Coast Sales Manager Brian Medford participated in the 3rd Annual Federal Asset Management Policy Forum and Expo in the Washington, D.C. area the week of October 17, 2016.

The first keynote speaker was Norman Dong, Commissioner of the General Services Administration Public Building Services. Another speaker was Leantha Sumpter Department of Defense Deputy Director, Program Development and Implementation Defense Procurement and Acquisition Policy. Also presenting was Mary Ruwwe, Facilities and Construction Federal Category Manager.

More than 30 other distinguished executives from public and private entities spoke on the subject of improved asset management for the U.S. Federal Government. Kennaw and Medford participated in the Risk and Review Work Group Panel that focused on the ways to reduce risks for the Federal Government. Also on the Panel was Keith Cunningham, Government Accountability Office, Assistant Director of Physical Infrastructure Team.

After a “big picture” overview of Risk and Review policy and recommended improvements to Risk Management, Kennaw and Medford offered specific ways to reduce risk with facility assets by increasing resiliency to blasts and natural disasters using Insulated Concrete Forms and advanced reinforcement methods.

Kennaw started by noting Fox Blocks’ recent investment in a Building Information Model initiative that makes construction information about resilient buildings available earlier in the planning process, making it available in design, construction and  throughout the project lifecycle.

Kennaw highlighted Fox Blocks’ involvement in BIMStorm, an online brainstorm using Building Information Models, as an indication of dedication to reduction of risk by making information securely available in all phases of a project.

Medford showed Fox Blocks’ long-history of involvement in Federal projects, showed blast testing that validates avoidance of bomb threats and listed many instances of ICF buildings surviving hurricanes, tornados, fire and storm surges.

Medford noted that the ability of ICF buildings to secure real property assets also helps protect personal property, IT and people from risks.

Fox Blocks “mini blocks” samples and product literature were also on display at the National Academies of Sciences historic facility where the Federal Facilities Council continued the activities of the Federal Asset Management Week, co-hosted by the Asset Leadership Network. A keynote speech was given at the historic facility by Admiral Thad Allen, USCG (ret.).

Fox Blocks involvement in BIMStorm was also noted at the National Academies of Science when Kimon Onuma, FAIA called for more availability of web-based information for owners from building product manufacturers and others.

At the National Academies of Sciences, Katherine Hammack, Department of Defense, Assistant Secretary of the Army for Installations, Energy and Environment, noted that a Colorado base has built a Net Zero building that cost less and took less time to build than the same building previously built with traditional methods. Fox Blocks was not involved in that project, but has contributed to other, super insulated buildings at the same base in Colorado.

Finally, Kennaw was involved in a Legislative Outreach on Capitol Hill that started with a briefing in the Capitol Hill Club and including Kennaw meeting with the Legislative Director for U.S. Rep. Brad Ashford, from Omaha, Nebraska, the home town of Fox Blocks parent Company, Airlite, Plastics. Kennaw informed the Legislative Director, Chris Kelley, about the week-long series of asset management events calling for increased focus on use of the ISO 55000 series of asset management standards to help save Federal tax dollars.

Kennaw said, “It is a pleasure and an honor to be involved with raising the awareness of improved asset management for our Federal government. We look forward to an ongoing relationship with the many organizations working to bring improved effectiveness and efficiency to U.S. tax payers.”

Kennaw also spent time with the Asset Leadership Network in Legislative Outreach activities on Capitol Hill where findings of the week’s events were presented to Senior Legislative Staff of Senators and Representatives.

Do you have a High Performance Window Buck that will stand up to these tests?

| Benefits of ICFs | Fox Blocks in the Field | Insulated Concrete Forms | February 4, 2015

Building Envelope Protection = Property & Life Protection:

During a severe weather event, the most critical factor for increasing the chances of a building’s survival is protection of all the openings to the outside. Once the wind enters the structure, the pressure changes lead to disastrous results.

Impact testing simulates windborne debris striking a window during a hurricane. Within the laboratory setting, this is done by firing a 2×4 projectile at predetermined locations on the window and seeing if there is any penetration.

The cycling portion of the testing ensures that a window having withstood impact by the 2×4 can then stand up to the rapid increases and decreases in pressure within the building during a hurricane.

ICFs and Severe Weather

| Fox Blocks in the Field | Insulated Concrete Forms | April 28, 2014

Severe Weather Starts its Seasonal Havoc

As we all are very aware, this time of year and throughout the early summer, is prime weather conditions for severe weather to occur. Most notably, tornadoes are a huge concern, especially in the Midwest. As of last night, tornadoes have started their annual ravaging of parts of the Midwest all the way down south. The tornadoes these last few years seem to be occurring more , bigger in size and staying on the ground longer. This brings us to the important issue of having a shelter that can withstand the winds and debris of a tornado, hurricanes, and other high wind forces. recently Fox Blocks just publish a quick overview on how to build an ICF storm shelter, check that out with the embedded video below.

Insulated Concrete Forms Build Safer Homes

By using insulating concrete forms for homes across the country, the home becomes a safe haven from tornadoes and hurricanes. This is one of the huge benefits we have always talked about with our type of product. The steel reinforced concrete, which can cure stronger than normal concrete because of the foam insulation, can withstand winds of over 200 MPH, and projectile debris traveling over 100 MPH. There are dozens of eye witness examples of ICF homes taking EF5 tornadoes head on with the walls still standing.

There have been lab studies done to prove its resilience to wind and there are stories and real world examples of homes, across the country, that have withstood natural disasters because of the unique attributes of ICF construction.

Stronger than Wood and Steel

Plenty of third party research on testing the strength of our ICF walls versus typical wall with wood and steel studs has been done. The chart below shows the strength of ICFs, so its easy to see why ICFs are left standing after a bout with mother nature.

Axial Capacity – pressure or force placed downward upon the wall from roofs, floors and walls
Wall Bending Stiffness – the strength of the wall structure to resist deflection
Lateral Capacity – sideways movement pushing against the wall due to soil, wind or earthquakes
Deflection – movement within a wall assembly

Type of Wall Axial Capacity (plf)
Wall bending Stiffness (psf)
Lateral Capacity (psf
Fire Resistance Rating
2×4 Wall Cavity @ 16″ o.c. 435 9.5 37.5 30 min-1hr
2×6 Wall Cavity @ 16″ o.c. 3220 37 80 30 min-1hr
6″ Core ICF Wall #4 @ 24″ o.c. 22,000 300 65 3 hours


Below are a selection of photos taken over the years of ICF homes withstanding hurricanes and tornadoes. In fact the Bay Waveland Housing Authority built with ICFs for all of these reasons we mentioned above. Now they are witnessing all the other benefits of ICFs: energy efficiency, HUGE savings on wind and general insurance, and providing safe homes for the community.
