Application / Environment
School natatorium. The indoor pool environment is subject to condensation buildup, especially during colder seasons, which can lead to mold and mildew growth. The air is also laden with chlorine and other chemicals that cause traditional building materials to corrode over time.
Location: Metea Valley High School (Aurora, IL)
Architect: DLR Group
Composite Design & Fabrication: Kalwall (Manchester, NH)
DLR Group designed the east facing translucent wall to slant outward using a thermally broken version of the Kalwall sandwich panel. The 4” thick panel was chosen to provide structural strength and superior energy performance. For visual interest, DLR Group opted for Verti-Kal, which incorporates internal, continuous support to provide a vertical emphasis and minimize joints.
The panels are produced using a continuous sheet panel process that embeds fiberglass reinforcement into a proprietary binding resin. Heat is applied to permanently set the materials into the durable translucent panel.
Kalwall Wall System: 3,709 sq ft (345 sq m)
Panel: Four-inch Kalwall 100 in Verti-Kal format
U-factor: 0.08 (0.45 W/m²k) thermally broken
Light Transmission: 5%
Interior face: 0.045 White Type 25
Exterior face: 0.070 White SW
Why This Solution?
Kalwall’s non-conductive, structural thermal break composite sandwich panel system eliminates corrosion and condensation (which can lead to mold and mildew). The systems are shatterproof and offer a long life as well as proven performance in every climate. The translucent yet highly insulating panels let light in while reducing HVAC operating expenses vs. other material options considered.
