translucent insulation

Home » Technology » Panel Technology » translucent insulation

In order to transmit visible light, Kalwall has developed translucent thermal insulation (TI) options, including Cabot’s Lumira® aerogel. Achieve U-factors between 0.53 – 0.05 as well as VLT% between 3%-50% and solar heat gain coefficients (SHGC) as low as .04.No matter the application, Kalwall has the right thermal insulation packages for even the most extreme environments.

 


 

U-values shown in bold denote thermally-broken grid core panels.
Visible light transmission (VLT) – NFRC 202, ASTM E-972 (approximate) as noted. VLT percentages over 30% are not recommended for most Kalwall applications.
Panel U-values include panel grid-core by NFRC 100 or 102. NFRC certified system U-values vary depending on framing. Project-specific Information available by request.
Shading Coefficient (SC) is equal to 1.15 times the Solar Heat Gain Coefficient (SHGC). *By calculation only (not by NFRC 201). By calculation only (not by NFRC 202)
