      08 45 23KAL - BuyLine 0421

• Kalwall's Sandwich Panel Skylight Systems over substructure designed and installed to maximum advantage of Kalwall structural capability. Spans up to 9'6" (3m) or more, depending on project conditions.
• Flat, curved or combination for skylight configuration design versatility and consistent with all Kalwall Systems. Easy, fast installation, coupled with large-sized panels to eliminate troublesome joints.
• To prevent water dams, all horizontal joints are "overlapped" - the ultimate in weatherscreen function to keep weather and water outside the building envelope.
• Class A Burning Brand compliant as standard.
• Underwriter Labs Class A built-up roof assemblies.
• NFRC-certified systems U-factor as low as .11 BTU/(hr/ft²/ºF) or 0.58 W/m²K .
• LEED^® contribution.

• Kalwall 100^™ panels are 4" (100mm) thick for applications requiring even more structural integrity. U-values from 0.08 to 0.15 BTU/(hr/ft²/ºF) or 0.45 to 0.85 W/m²K (R-13 to R-6.16).

• Super-insulating, light-transmitting Kalwall+ Nanogel^® infilled with translucent aerogel for R-20, panel U-value of 0.05 BTU/(hr/ft²/ºF) or 0.30 W/m²K with 20% light transmission.
