Insulated Sandwich Panels - Modular Building Solutions
FP McCann's precast sandwich panels provide precast concrete insulated sandwich panels that can be clad with a variety of finishes, eliminating many of the pitfalls associated with traditional building methods.
Design & Composition
The panels, constructed off-site, comprise an outer leaf of precast concrete, an insulating layer and an inner leaf of plain grey concrete with a power floated finish. The external skin is connected to and supported off the internal skin using proprietary plastic epoxy ties. The ties have a low thermal conductivity and as such eliminate cold bridging. We can modify the thickness of the insulation in order to accommodate the required U-value. The shape, thickness and size of the concrete can also be made to meet the requirements of the project.
Panels are joined together using a specialized joint fixing system on the inner leaf which ensures maximum strength and airtightness. Each panel slots together, aligning wire loops that protrude from each panel. A steel rod is then fixed through the wire hoops and the joint filled with a thixotropic grout.
Panels can form part of a precast structural frame where the inner leaf is load bearing or may be attached to a steel frame as a cladding panel.
