PTI Solar Energy Diffusion (SED) Anti-Reflection Screen for Windows Prevents Melted Vinyl Siding, Destroyed Outdoor Furniture, Blistered Auto/RV Paint, & Eye Injury.

The phenomena of concentrated ultra high energy light beams formed by reflective and/or slightly distorted window panes has been authenticated. The focal point of these beams can exceed 300 degrees Fahrenheit.

PTI SED screen is engineered and formulated to exacting technologies designed to scatter the reflected light rays and keep them from becoming a single intense beam. The patented extruded fiber construction creates a diffracted pattern and the powerful solar energy is diffused.
Window with SED screen attachedSections of PolyCB2 SED screen are cut to exact size for mounting directly to the exterior glass of the offending window. Any size or shape can be made. PTI Grip Lock pads (1" clear vinyl, Velcro acting) are fused to the screen (8" to 12" apart) on the edges and mating pads are provided for adhesion to the glass (see alternate mounting methods below).
