I'm trying to resolve a problem with a walk in freezer and 2 walk in coolers. All three units are experiencing condensation on the panels (up to 24" high) and in some cases on the floor with in the first 12". These unit are located in air conditioned space but when it is warm out the condensation goes on the floor and creates a fall hazard.
All three units have the concrete floor with 4" of insulation underneath it surrounded by wood sleepers (nailers). The units are all Kolpak and are about 7 years old. We took a small section of a cooler apart a few week ago and the there was moisture coming out from between the panels and there was a fair amount laying in the screed. We were thinking that maybe the water was there because of condesation on the locking cams during the warm up process. In addition the wood sleeper was not centered under the screed and was on the very outside edge.
Since these units were installed Kolpak now utilizes an insulated screed under the panels. Does anyone know of any other upgrades that Kolpak has made in the last 5 -7 years that may be insulation / condesation related? Similar problems? Bad panel construction?
Several people think the subfloors were constructed incorrectly. The problem is if I tear the floor apart I will distroy the concrete and insulation and never really know what the real issue is, unless it works. If it doesn't work I'm out a whole lot of money chasing this thing.
Any history on the evolution of the Kolpak walk in freezer & coolers would be great. Any ideas on how to be sure what the problem is before we make a sizable financial commitment?
I've been reading the threads and someone out there has got to have some input on this topic. Any feed back is greatly appreciated. Thanks in advance.
