Anyone have research links for water curtain/water wall use for exposure protection? My understanding is that thinking is water curtains do not work for protecting exposures from radiant heat.
I have no experience with these but a local mutual aid partner is planning a training burn of a junk house and wants us to operate a waterwall (after they buy one) to protect the house next door (20').
I find such equipment in Elkhart and Pok catalogs in 1-1/2" or 2-1/2".
Links or experince (I tried seach no luck with is surprising)?
