Frequently Asked Questions

What’s the best infill panel for high thermal performance in curtain wall systems?

The Mapes-R+ rabbet edge panel is an ideal solution for maximizing thermal performance, as it can increase a project’s R-value by up to 500% without requiring modifications to the existing frame. These high-performance infill panels are perfect for curtain walls, windows, storefronts and spandrel areas where energy efficiency is a priority.

How do Mapes-R+ infill panels support "zero-energy" building designs?

Mapes-R+ infill panels are specifically suited for “zero-energy” buildings because they are available in thicknesses up to 6 inches. Their unique 8-ply typical cross-section, which includes an exterior skin, multiple insulating cores and intermediate substrates, provides unrivaled thermal resistance compared to standard glazing options.

Can these infill panels fit into standard glazing pockets without frame modification?

Yes, Mapes-R+ rabbet edge panels are designed to fit easily into any standard glazing pocket, including 1/4-inch retrofits. This design allows the interior side of the infill panel to be significantly thicker than the glazing pocket itself, providing maximum insulation while maintaining compatibility with existing framing systems.

How do Mapes-R+ panels help reduce installation time and labor costs?

Using Mapes-R+ infill panels reduces field labor costs by eliminating the need for backpans and additional insulation. Because the panels integrate multiple layers of core and substrate into a single unit, they simplify the installation process for glass companies and glaziers.
