KnuckleHeads Prevent Split Tip-overs in High Winds Roof-mounted heat pump splits are often attached to 4’ X 4’ treated wood beams, which are loose laid on the roof membrane. While this has been common practice for many years, the emergence of taller “double stacked” units has created a new problem: “wind sailing.” Contractors and building [...]
KnuckleHead Rooftop Supports: The Secret Ingredient The KnuckleHead support has been carefully engineered and features a distinct design. But there is something else unique about it: the material from which it is made. That material is a high-performance polymer called Nylon 66. Nylon 66 possesses properties that make it ideal for the conditions a rooftop [...]
Can a Simple Rooftop Support Be “Engineered”? Rooftop supports for pipes and HVAC equipment come in a variety of shapes and sizes, and, of course, prices. Some feature a base made of recycled rubber and a metal top for supporting pipes or struts. Some are simple one-piece units composed of molded plastic, some are [...]

Edwards, NWIR Communications Chair and RCS Editor. GREEN LINK Engineering’s Sales and Business Development Coordinator, Dana Castle, decided that was excited about attending the [...]
Rooftop Supports: What Do Adhesive/Sealants Bring to the Party? Many, if not most, rooftop supports are loose laid. This makes for easy installation of pipelines, air conditioning units, conduit and other rooftop equipment, but loose laid supports present a potential for problems down the road. Over time, equipment vibration and wind gusts can cause [...]
Because rooftop supports aren’t typically specified, they are often improvised. A well-constructed commercial or industrial building must meet a host of specifications. The roof is no exception, and neither is rooftop mounted equipment, including pipes, conduit, HVAC/R units, solar arrays, etc. Yet between such equipment and the roof membrane is an area—an interface—where there is [...]
Elevating and leveling roof-installed pipelines and HVAC equipment are more important than may appear at first glance. There are two issues: First, pipes, equipment or electrical conduit need to be elevated to a point where debris, sticks and leaves, snow and ice cannot be trapped underneath causing a dam that will lead to ponding [...]
Is protecting a $55,000 roof job worth a few hundred dollars? Recently, a building owner in Michigan contracted for a re-roof of his building. A ten-man crew installed a PVC membrane to the roof. Pipes and HVAC equipment, originally positioned on wood sleepers, were moved to allow for the installation. Once the job was [...]
Why Wood Sleepers Are on their Way Out The use of wood sleepers to provide rooftop support for HVAC equipment, pipes, and conduit has been a standard procedure for many years—the method goes way back to the first days when pipes and equipment first began to be installed on roofs. It’s easy to see [...]
The KnuckleHead Solar Support System There are two main types of solar mounting systems: Mechanically attached or ballasted. KnuckleHeads by GREEN LINK, Inc. are mechanically attached. KnuckleHeads feature a simpler, integrated end-effective design that combines attachment and a solar-ready support head in one unit. Typical solar support products function strictly as attachment bases that [...]
