Wire Truss

Wire Truss

Welded wire truss helps produce energy savings in

precast “sandwich” panel construction

A precast sandwich panel consists of a bottom layer

of concrete, a middle layer of insulation, and a top

layer of concrete. The Wire Truss connects these

layers into a single, composite unit that is far more

energy-efficient than a solid, concrete-only panel.

Wire Truss has the resiliency to expand and contract

with the independent thermal-induced movements of

the inner and outer concrete layers. This maintains

the integrity of the panel and minimizes any thermal

transfer between layers.

The design of the concrete and insulation layers

will establish the overall panel thickness and truss

spacing. The panel thickness will indicate the height

of the Wire Truss. The truss spacing will determine

the quantity needed.

Wire Truss is used to connect the bottom and top

concrete layers in a precast “sandwich” panel. Foam

insulation is placed between the Wire Truss to create

an energy-efficient panel.

Wire Truss heights from 3” to 9” in 1/2” increments,

lengths of 10’ or 12’, and/or a galvanized finish are

available on request

Top Wire – Max .306 / Min .225 inch diameter

Bottom Wire – Max .306 / Min .225 inch diameter

Diagonal Wire – Max .243 / Min .192 inch diameter

The diagonal wire is welded at all the intersections of

the top and bottom wires.

03/26Installation

1. Install bottom width mesh and place lengths of

Wire Truss in predetermined locations in the form,

tie securely to mesh or pre-stressed cables.

2. Place bottom layer of concrete and raise/rotate the

lengths of Wire Truss to a vertical position, such

that 2/3 of the Wire Truss is out of concrete.

3. Install insulation board between the lengths of

Wire Truss, pressing the insulation board in and

around the diagonal wires. Tape or caulk any gaps

to prevent concrete from “bridging” the layers.

4. Install top width mesh or pre-stressed cables and

tie securely to the Wire Truss. Place and finish top

layer of concrete to complete the insulated panel.
