An overview of partially composite insulated walls that covers general information regarding structural and envelope performance as well as overview of the testing program and generalized conclusions.
Since the early 1980s, insulated concrete sandwich panels have been utilized as a design and construction technique for tilt-up. These types of panels are comprised of an inner and outer wythe of concrete, separated by a layer of rigid foam insulation. Connectors are used to fasten the two wythes of concrete together. To date, the majority of the insulated panels have been designed using non-composite action, meaning that only one wythe of concrete was considered for the panel’s structural integrity. The widespread acceptance and adoption of the International Energy Conservation Code (IECC) has reinforced the insulating benefits of sandwich panel systems and motivated many in the tilt-up industry to take a closer look at ways to maximize performance and constructability by creating a standard for composite behavior of insulated systems. To that end, the Tilt-Up Concrete Association (TCA) has collaborated with the University of Nebraska’s Durham School of Architectural Engineering and Construction to conduct what is believed to be the largest, full-scale field testing of this type with the goal of developing a slender wall design methodology to predict composite behavior under combined axial and bending forces.

Our team has been in the architectural precast / pre-stressed business for over 40 years. During that time we have made insulated wall panels using every system. We understand which designs work and more importantly which do NOT work for various reasons including; design code, production efficiency and engineering requirements.

We have always looked at tilt-wall as an evolving artform. There are many things that we considered pushing the envelope a decade or two ago that are now commonplace or outdated. At Seretta, we take our role as an industry leader seriously and are constantly looking for and trying out potentially new and better ways to perform our work. We know that if you become complacent, you will become outdated. At Seretta, we use only the latest and most advanced chemicals, equipment, software, methodologies and technologies so that we continue to produce the highest quality work in the shortest amount of time.
At Innovative Structural Solutions (INNSTRUCT) we have developed the Total Integrated Panel System (TIPS), a technology and process that acts as the primary structural and insulating member in conventional tilt-up construction. TIPS sets 4" of expanded polystyrene between 2 layers of welded wire mesh fabric. These are then joined together by diagonal truss wires. Because of the extreme strength of this pyramidal system, TIPS walls can be built with as little as 5" of total concrete in a 9" insulated tilt-up panel. The system reduces the amount of added rebar by 60-90% and concrete material by 30-50%, depending on the panel design. This drastic reduction in materials, along with the incredible strength of our system, creates a panel that is up to 50% lighter and much easier to work with than traditional tilt-up methods.?
