Subtle but effective was the objective for Walker Glass in developing its new AviProtek T product, a bird-friendly acid-etched glass solution that is “hardly noticeable” to the human eye, according to the company.
That goal was attained with the contrast created by the UV markers and the acid etching on the outside surface of the glass. The transparent product can be used in insulating units and can be combined with a low-E glass on position 3.
The design follows the “2- by-4-inch rule,” established by field experiments conducted by conservation experts. According to Walker, “Most birds will not fly into surfaces that have two inches or less of untreated horizontal space or four inches or less of untreated vertical space.”
Area (STC) 41
Thermal Windows Inc. has developed door and window products that it says achieve performance ratings as high as STC 41. The company is marketing the high STC thermal windows, terrace and sliding glass doors for projects in areas subject to high exterior noise, including hotels and extended-stay facilities, urban-area apartments and condos, military offices and housing and structures near airports.
In addition to the sound reduction capabilities, the windows achieve U-values as low as .34 and provide AW75 or higher structural performance.
A Small Move
Ergo Robotic Solutions’ two new models in its product lineup—the GM 800 and the GM 1200—are built upon the same design as the GM 2000-12 but in smaller fashion.
The GM 800 has a lift capacity of 800 pounds and can lift a load to a height of 10 feet to the center of the lift hub, according to the company.
The GM 1200 has a lift capacity of 1,200 pounds and can lift a load to a height of 11 feet.
The standard powered articulations include three boom movements and both vertical and horizontal tilt. Optional add-on power articulations include lateral side shift, rotation and EZ Pick, an Ergo innovation for picking up and placing a load in one smooth movement.
