Hello,
I am doing a remodel and I have the kitchen and adjacent bathroom completely ripped out along with floor joists.
I am considering using the warmboard for the subfloor here. However if I want tot distribute the floor system to the rest of the house I am not sure about loosing the 1 3/32" space(if a lay on top of the existing subfloor) in the rest of the house.
I was looking at the warmzone material because it is 5/8" thick.  can I incorporate the two together?
Any one used warmzone?

Thanks! RB

how large of an area are you doing, and do you have an existing hydronic system?

The major renovation is the bathroom/mudroom and Kitchen(432 SQ ft). I had to remove subfloor and Joists. The old farm house has an existing fuel oil forced air. Which does nothing but burn fuel. So I have a wood stove on the main level. However, that does not het the kitchen and bath well. So i am contemplating removing the forced air and going to radiant heat for the Kitchen and Bath/mud rooms. Then I would want to build out the radiant heat to the rest of the house. I doon't have a godd handle on the square footage for the rest of the house(which includes bedrooms on the second floor. So I am contemplating creating zones - 1 for the Kitchen and bath/mud, 1 for the living room, office and bedroom in the main floor, and 1 for the 3 bedrooms upstairs on the second floor. Which leads to me to ask about warmboard and warmzone. I don't see as much conversation about warmzone. I will take some measurements tonight. Sorry I just started considering the radiant heat project.

well, if you're only going to do 432 square feet, I'd probably just do the electric system rather than installing a hot water system for an area that small.

If you going to do a larger area, then a hydronic system might make more sense if it allows you to use a cheaper energy source.

There are plenty of ways to retrofit radiant though. There are prefab panels that go on top of the subfloor that are thinner than the 1-1/8" warmboard, there are joist mounted applications.. lots of ways to skin that cat.

You can even mix and match, but I would not install a hot water system for a very small area, it's just unnecessary cost and complexity unless you're doing a large enough area to worry more about energy cost and flexibility I would say. Hope that helps!

If I put it in at all I want to put it in the rest of the house. It is just that I have to do it in stages. I was considering the warmboard, intially, because i have to put in new floor joists. But i don't really want to pull up the existing subfloor in the rest of the house. So i was considering Warmboard for the kitchen and bath and then the warmzone or some other panel that installs on top of the subfloor to save room. The mix and match is what I was wondering about.
Does it work out ok? Or since i would use a panel on top of the subfloor perhaps I should do that in the kitchen also?
Any reccomendations on panels that install on top of the subfloor?

well the structural subfloor aspect of warmboard is handy, for sure.

If you're talking about the hydronic panels warmzone carries, it appears to be a rebranded thermalboard... not in the same class as warmboard, in my opinion. I wouldn't mix and match those two.. that is, I wouldn't mix them.. they don't match very well ;) I assumed you were talking about electric there because they do a lot more with electric I believe.

it all depends on the heat loads you are servicing though. If the kitchen has restricted floor space and a high load, and the other areas don't, and they have similar floor coverings, warmboard and the weaker thermalboard might mix ok. If they have similar loads per square foot, perhaps not. "matching" in this case means, "needs similar water temperatures". If one needs much warmer water than the other, you can have less desirable results.

Other options are Raupanel (similar to warmboard) by Rehau, which is also 5/8" high. A DIY sandwich (not similar, but closer than thermalboard) is 3/4" in height. Climate Trak/Quik Trak (not similar) is 1/2". There are lots of others as well... can't really list them all here ;)

And a joist system, say, with extruded aluminum plates for performance of course doesn't add any height. It will perform similarly to most of these panels, though not warmboard/raupanel.

I agree with NRT.Rob regarding going with electric vs. hot water in a small to medium sized area. They are super efficient, last forever and aren't a hassle to install. The cost to design, install and maintain a hot water system are more times than not overwhelming. As a remodeler I call on Warmzone to help me out and they usually have a product, system or a good referral on where to go for the best radiant heating system. Warmzone is a national distributor of lots of products for remodeling projects and does not make the Thermalboard discussed earlier. Warmzones product choices, prices and most of all their support is what I rely on to get the right heating system in cases like this.
