Solar Control Devices

PPC is able to provide the design professional an assortment of exterior solar control devices to help in reducing solar heat gain within and along building structures. Using a variety of materials and styles we can provide vertical, horizontal, cantil-evered or inclined projections that meet your design criteria. Blade configurations and spacings can vary to filter up to 80% of the sun’s heat and light level. Dynamic wind loads are a consideration with this type of application. Support rods and connecting hardware may be used from above or below to address design loads and aesthetic values. Support rods may be extruded aluminum or stainless steel.

Design Guide for Solar Control Devices
DESIGN GUIDE

Aesthetic appeal and solar management have now become an increasing development on new construction within in the architectural community. The goal is to provide the architect and owner a product that can reduce the “cooling load” with the use from passive solar shading devices.

SELECT THE ATTITUDE FOR THE ASSEMBLY

Horizontal
Inclined or Sloped
Vertical

SELECT THE ALUMINUM BLADE CONFIGURATION

“Z” Style, available from 4” and 6
Elliptical, available from 4” , 6" and 8"
Rectangular, available from 4” x1" and 6"x1"

CHOOSE A SHAPE FOR OUTRIGGER CONFIGURATION

We offer tube sections from either single piece components or "self-mating channel" components. These outrigger elements can be 4"x2", 6"x2" or 8"x2". Beyond this we also offer custom bar outrigger configurations which can shaped or tapered to almost any profile. Peachtree Protective Covers will develop sections and systems around any given idea or challenge.

SELECT THE BLADE SPACING

Space the aluminum blades to a set pattern that so that the direct sunlight does not impact the window area which will adequately reduce the “cooling load” within the building structure.

CHOOSE APPROPRIATE FINISH

Selection of finish greatly affects the installed cost of the solar control device system. Clear Anodize is the most cost effect finish. To introduce color, a fluoropolymer resin based paint must be used. These are paints typically known as Kynar, Hylar and Duranar and are high end finishes which come in a wide array of colors. These premium finishes are the most costly available for solar control device systems and can vary greatly depending on the color selected

INSIST ON AN ENGINEERED SYSTEM

The solar control device must be designed to withstand all appropriate loads without failure in stress and deflection. Structural calculations, signed and sealed by a registered Professional Engineer are an essential part of a quality solar control device.
