Kalwall Cutaway Diagram
1) Aluminum or thermally-broken Grid Core composed of a series of interlocking I-beams
2) Interior shatterproof Fiber-Reinforced Polymer (FRP) face sheet formulated to meet finish, flame and smoke requirements of the toughest international codes
3) Translucent Insulation (TI) options, including Cabot’s Lumira™ aerogel offer exceptional thermal up to 0.05 U
4) Color stable, exterior Fiber-Reinforced Polymer FRP face sheet with a permanent glass veil erosion barrier to eliminate fiberbloom
5) Clamp-tite™ aluminum fastening system, specifically engineered and available as either standard or thermally-broken with many finish options
6) HC and E-Series fixed and operable windows, fixed louvers, even opaque panels can all be factory-unitized to add areas of ventilation and vision glazing
As the inventor of the translucent structural sandwich panel, Kalwall® provides museum-quality daylighting™ with superior thermal packages. Lightweight and low-maintenance, whether its being designed for a wall, roof or specialty application, consider our high performance translucent building systems for your next project. Both structural and diffuse light-transmitting, Kalwall performs as an excellent thermal envelope, especially when compared to polycarbonate systems and most insulated glass units (IGU). We hope that you enjoy learning about the basics of our unique fenestration technology.
Translucent Fiberglass Reinforced Polymer (FRP) Faces
We produce a selection of translucent FRP to meet a wide range of project applications including specially formulated, exterior rated FRP as well as high impact, vandal resistant, UL and FM options. White and Crystal are standard. Kal-tints are optional.
Structural Grid Core
The Kalwall® panel’s structural grid core provides strength while being extremely lightweight. That said, each core configuration performs differently. In general, more vertical mullions and tighter grids allow for longer spans and more panel stiffness. Both standard aluminum I-beams and thermally-broken interlocking I-beams are available.
Translucent Insulation (TI) Thermal Packages
U-factors (only thermally broken panel values shown above) + VLT% ranges for 2-3/4″ thick Kalwall® panels
U-factors (only thermally broken panel values shown above) + VLT% ranges for 4” thick Kalwall® panels
Numerous translucent insulation options are available between 0.29-0.08 U-factor. For the most demanding applications, Kalwall® offers a 0.05 U-factor (R-20) Lumira® aerogel option (available in 2-3/4″ thick panels only | limited grid-cores options available). TI specifications affect not only thermal performance but visible light transmission (VLT%) as well so please consult our sales team to optimize your design including our complementary daylight modeling services.
As you can see, there are many considerations when designing and specifying with Kalwall®. Please contact us for further information from one of our Sales Representatives based on your project specific requirements.
