PVC Duct Rainskirt

PVC duct rainskirts are commonly used to deflect rain and prevent possible leakage issues. Rainskirts are usually found on roofs where PVC duct penetrates the top of a building. Like all PVC duct parts, these rain skirts are made of corrosion resistant material that does not rust or pit like traditional metal ducting. PVC parts like this skirt can be installed using solvent cement or hot air welding (for larger sizes). They are available in a range of sizes, from 2 inch through 24 inch, to suit your unique duct needs.

When PVC duct runs vertical out of a roof, it creates the opportunity for the elements to enter the building if not properly sealed. One way people prevent leaks is by using a rain skirt. The PVC rainskirts we carry “bell” or flare out at the bottom to allow any falling water to roll off and away from the opening of the building created for the duct to pass through. Smaller sizes may be molded, while larger sizes may be fabricated and rolled from PVC sheet.

It is often necessary for a duct line to run from the inside to the outside of a structure so the line can vent. Vents are sometimes located at the top of a building, and they allow any built up air or fumes to escape. That is why rainskirts are often paired with vent hoods or rain caps. The skirt diverts water away from the duct line. Unlike alternative materials, PVC duct is lightweight and simple to install. It is an attractive option for vent, fume, exhaust and drain.
