Polyurethane foam and sprinkler pipes
« on: September 19, 2014, 04:31:03 PM »
Interesting bulletin from the states:

http://osfm.fire.ca.gov/informationbulletin/pdf/2014/IB_SprayPolyurethaneFoamApplication_5-27-2014.pdf

It talks about the effect the spray foams have on plastic sprinkler pipework, it seems the major concern comes from the heat produced by the foam when it cures and this affects the plastic.
