Maxblock Sunshades
Effectively reduce solar heat gain by shading vision glass areas of the building envelope with Tubelite’s MAXBLOCK Sunshades. Cooling costs can be significantly lowered, while still allowing natural light to fill the workspace. MAXBLOCK Sunshades are designed for use with Tubelite 200 Series or 400 Series Curtainwalls. A unique, easy to install outrigger bracket fastens at the pressure plate area and allows removal of individual sections of sun shade for reglazing applications.
A variety of architectural profiles are available to complement surrounding elements. Three outrigger types with corresponding blade styles and facia caps can be selected. Each type can then be extended from the building in projections of 20”, 25”, 30” and 35” to provide the desired performance. Blades are attached to the outriggers using simple screw spline connections.
LEED Program points are available for reducing building energy costs for cooling while supplementing interior lighting (Energy & Atmosphere Credit 1, 1-10 Points). Estimate the Solar Heat Gain Coefficient on the glass by geography using our convenient tables. See Tubelite’s technical data in the full product information binder.
