Insulated Precast Concrete Wall Panels

Precast concrete insulated sandwich wall panels have gained popularity over the years but some industry professionals are still not familiar with them.

Insulated precast concrete wall panels.

Insulated precast concrete wall panels can be created as a complete system that includes insulation and a moisture barrier as well as an exterior membrane and interior finish. This allows the structural performance to be based on the full thickness of the panel. An insulated precast concrete wall panel or sandwich wall panel as it is sometimes called is a precast concrete wall panel with two layers of concrete separated by a layer of rigid insulation see figure 1. With very low thermal conductivity the high strength c grid connectors help deliver a sandwich wall panel with insulation values up to r 37 depending on the thickness and type of foam insulation.

Carboncast high performance insulated wall panels are composed of two concrete wythes separated by continuous insulation c i. Thin wall is a structural load bearing insulated precast building envelope system that features composite action between concrete wythes. These components come together in one simple to install system that can be erected in much less time than traditional building methods. Composite panels connect the two wythes of concrete without penetrating the insulation with a conductive material.

A typical warehouse can be erected in a week. As with architectural panels insulated sandwich wall panels can be strictly architectural strictly structural or a combination. The two layers of concrete often referred to as concrete wythes are connected by one of many wythe connecting systems. Reasons for their increased use in place of more traditional materials include.

The system enables a very energy efficient building with edge to edge eps or xps insulation without thermal bridges and uses less concrete than traditional structural wall panels.
