PPI publishes new technical document for installing plastic pipe near recessed lighting

The Plastics Pipe Institute, Inc. (PPI), has published a new, free guide related to the installation of plastic pressure pipe materials in the vicinity of recessed lighting fixtures.

Technical Note 56 (TN-56) Installation of Plastic Pressure Piping Materials Near IC-Rated and Non-IC-Rated Recessed Lighting Fixtures provides guidance to installers of CPVC, PEX, PE-RT, PP-R and PP-RCT piping materials about protecting these piping systems against excessive heat through distance, insulation, or other means.

According to Lance MacNevin, director of engineering for PPI’s Building & Construction division, explains the piping materials commonly used for residential and commercial systems are rated for continuous high-temperature operation, “But every material has limits.“

Adding that, “Certain light fixtures may have exterior temperatures as high as 194°F. Frequently repeated or long-term exposure to air or surface temperatures above 180°F may have negative effects on some plastic pipe materials.”

TN-56 can be accessed on PPI’s website directly at https://plasticpipe.org/pdf/tn-56.pdf. Additional information about piping materials for building and construction  can be found online at https://plasticpipe.org/building-construction/index.html .
