gypcrete installation cost?

michael terry

can anyone tell me about what it would cost to have gypcrete installed on 2000 sqft on a single level. I am getting ready to start building my house and so far cant get an email response from anyone to do the job.could I do it myself? the house Im in now I installed staple up. the wife wants tile thru the whole house so I was thinking gypcrete would be the way to go , lower water temps and all that....any thoughts?
thank you

It will vary a bit

from location to location. Depends alot on cost of shipping the raw material and how far the installer has to travel all the equipment. Have you tried contacting installers through the manufactures websites? Hacker, infloor USG.

It is possible to install tile floors and heat them from below the subfloor without gyp pours.

First we would have you do a room by room hestload calc. then you can build the system and chose the emitter type to handle the job.

Low mass dry systems do have some advantages in response time and ease of retrofit-ability. Check out all the options, plenty around these days.

If your handy try lightweight concrete [exploded aggrigate] with fiber mesh added, be sure to account for xtra weight on floor joists aprox 14# / sq ft. @ 1.5 inches slightly
more than gypcrete but it has better heat transfer characteristics, impervious to water after drying, won,t scuff or scratch under normal conditions, material should cost less than gypcrete and there is no special equipment req'd, staple 4 mil plastic to plywood then tubing and your good to go. Build your walls on bigger bottom plates, makes for a nice nailer for moulding and a screed for finishing concrete. If your going to be light on labor add a retarder to slow down the drying process. Advise a pro for heatloss / boiler and tubing sizing.

WHHAAA???

I'm familiar with no product poured at 11/2" depth that exists as a final finish surface. Lightweight (structural) concrete should be poured 2" or higher; Gypum must be covered with a finished floor, either tile or hardwoods, with pre-engineered flooring working better.

Most homeowners should not attempt the installation. These products are specially mixed and pumped into the home...by professionals. Any pour "hand screeded" over 100SF is asking for trouble, (when done by a homeowner). BTW, Fiber mesh does not increase heat transfer...it increases strength.

I will be

building in the southwestern tip of virginia and there is going to be a heat pump system regardless this is a pet project of mine that stands a good chance of getting lost in budget cuts . I work in the heat and air field and radiant floor is of great interest to me. we love the staple up job I put in our present home. I guess at this point I am a victim of my own mechanical dreams.but the budget has ways of bringing you back to reality.I am using floor trusses so staple up would be easy thats for sure.
thanks for your input

Actually, Paul

USG was showing a high (8000psi)psi wear surface at the RPA show several years ago. As I recall it could be colored also and used as a final finished floor.

Think I would look hard at Warmboard if the home is still in the design phase. It really brings the best of all worlds with a very stout subfloor and solid wall to wall aluminum transfer surface. Hard to beat that for excellent transfer and heat spread.

Gypsum concrete

The other benefit to a gypsum pour is that the house is very quiet. It is used as a sound deadener between rooms and between floors. And you will not hear any tube expansion within a concrete pour. Also you have freedom to design your tube spacing and placement to your heat loss load. You are not constrained to following a fixed pattern. And yes I do pour gypsum concrete. I also use dry systems when appropriate. I prefer Rehau's ruapanel when a poured underlayment won't fit. It seems to have the best heat transfer,ease of installation and work with all coverings. It is not cheaper than a poured underlayment in my offering though.
