Tubos Inc., manufacturer of the popular Tubos line of pre-engineered vent stack extensions, has extended its product line with a 5-inch diameter vent stack extension for commercial roofing applications. This addition rounds out Tubos’ line and provides options for 95 percent of the vent stacks on commercial roofs in the U.S.
Patented Tubos pipe extensions are now available in 2-, 3-, 4- and 5-inch diameters to accommodate most common vent stack sizes. Tubos products are fully compatible with both cast iron and PVC vent stacks, and each Tubos unit features a six-inch internal splice sleeve that prevents water and moisture from leaking into the roofing assembly.
Tubos provides an easy and cost-effective solution for extending vent stacks on commercial buildings. When insulation is added during a re-roofing project to meet building code R-value requirements, the height of the vent stack over the roof is effectively shortened, and frequently takes the vent stack out of building or plumbing code compliance.
Tubos units are installed in four easy steps. Just measure, cut, seal, and flash and you’re done. Plus, each 28-inch long unit can be cut and used to extend two pipes, and extensions can be up to 16-inches long. They are ideal for use where a tapered system is added, or a new lightweight insulating concrete deck is being poured.
