Are there any thoughts or ideas concerning development of a new antifreeze which doesn't have the flammability issues of propylene glycol or glycerine (and the possible timeframe of when it could be on the market) ? A local fire authority I spoke with yesterday gave options of heat-tracing (or heat taping), insulation or a dry system to protect an apartment building which has a row of attic heads at the ridge and a layer of piping running on top of the bottom chords of the roof trusses to supply the heads in the units below. (The lower layer of pipe will be covered with R-38 loose fill insulation). How can it be determined if the R-38 insulation will adequately protect the piping below if it is revised into a wet-pipe system ? The piping that is above the insulation will likely be revised into a dry system. But this is only one job and thinking of all contractors and projects out there, the scope of these TIA's is pretty significant. I would imagine that somebody is working towards development of a new antifreeze formulation and just wanted to check if anyone has heard of such.
