Omega manufactures a composite insulated wall system called Thin-wall (www.thin-wall.com). Although we still produce many non-insulated jobs, our insulated panels are becoming very popular. Thin-wall is a new system that uses thermally non-conductive Nu-Tie shear between the wythes (layers) of an insulated panel. This connection method creates composite action between the layers of the panel and makes a very thermally and structurally efficient wall. For example, a 3” concrete/4” insulation/3” concrete panel can have structural capacity that approaches that of a solid 10” thick concrete panel. The longitudinal cross section of the panel looks similar to a truss, and it is no problem for these panels to act as load bearing wall panels. This system is the most robust, versatile, and effective system we have used (and we have used many).
The system allows edge to edge insulation with R-values up to 20. Because of the reinforcement method, the panels are lightweight and efficient to ship and manufacture. The efficiency of the material usage also makes the environmentally friendly.
Other advantages of this system and precast in general:
- The panels can produced with a large variety of exterior integral finishes.
- This interior of the panel can be manufactured with a trowel finish that can be painted.
- Electrical items can be embedded for a clean appearance if desired.
