Hardwood Flooring Over Radiant Heated Concrete

dear Tim,

How do I install
3 quater inch hardwood flooring on a outside porch???????????????????

Donald,
I would use galvanized nails...... I assume this floor will NEVER get wet, right?

DEAR TIM,
I AM CONSIDERING "BUILDING" A PERMANENT YURT OF 30" AS LONG TERM TEMPORARY HOUSING WHILE I BUILD. DO YOU SEE ANY SPECIAL CONSIDERATIONS FOR USING WOOD FLOORING OVER A RADIANT CONCRETE SLAB OTHER THAN THE CURVATURE OF THE SIDES (AND HOW TO FINISH THEM). SHOULD A SYNTHETIC SUCH AS PERGO BE A BETTER ALTERNATIVE? I BELIEVE THAT AFTER THE RADIANT SLAB WAS FINISHED, THE STRUCTURE WOULD NEED TO BE ERECTED SO THAT THE CONCRETE COULD DRY AND WOOD COULD STABILIZE WITHIN. HOW WOULD YOU SUGGEST FINISHING THE "RAW" EDGES OF THE CONCRETE/WOOD? SINCERELY, CYNTHIA CIANI

Cynthia,
You need to pose these questions to the manufacturer of the flooring you end up choosing. Not all floors play well with radiant heating and latent concrete-slab moisture.

Dear Tim,
I've installed radiant heating in concrete and under a wood floor (between the floor joist). Should I be concerned with the boiler water temperature under the wood floor or therunning through the tubing in the concrete? Sincerely, Marty

Marty,
Did you install the flooring according to the specs I outlined above? You can put the tubing in concrete.

can babmboo flooring be installed over hydronic radiant heated floors. the subfloor is wood/sleeper/sandwich pex-tubing installation method

George,
The people who make the bamboo flooring have the answer to your question.

When laminate flooring is installed over concrete with radiant heat in an older home, is it necessary or recommended to turn the heat off prior to installation?

i want to install hardwood with sleepers underneath.can you pour mud in between the sleepers.do you need to put wire down under the mud.we want to use 3/4 by 31/4 quarter sawn select red oak and install oak on top of sleepers.if you can help that would be great. thanks john

I would like to install a hardwood floor on a concrete slab. I live in Northern Jersey. I would like to install radiant heat under the floor. What do you recommend?

Dear Tim,

We are installing a concrete floor with radiant heat. This concrete floor is the finished product, no hardwood or tiles, maybe eventualy.
Where do I put the insulation? In between the joists and leave an airpocket, or on top of the plywood subfloor.
Thanks

I have a 50 year old house with nice solid oak floors and would like some advice as to whether putting tubing and radiant heat under them would cause any damage to the floors with them being so dry and stable. We live in Calgary with a similar dry climate to NM...colder with more heat needed to keep us warm

Thanks
Warren

Good morning,
We bought an 800 sq foot house with no basement and want to know if installing radiant heat floors would be possible and if yes, about how much would it cost (ball park of course).
Thanks much!

I have to install a solid hardwood floor over concrete, I know I need to use sleepers, but I can't find anywhere the distance between pieces or any other useful info. The wood will be 3 1/4" x long random lengths and the house is still being framed in.

HI I LIVE IN SOUTHWEST GA, AND MY FIANCE AND I ARE BUILDING A HOUSE WE HAVE CONCRETE FLOORS AND WERE WANTING TO PUT ENGINERED WOOD FLOORING IN. SOMEONE SAID THAT WE HAD TO HAVE A MOISTURE BERRIER. IS THAT TRUE. IT MAKES A LITTLE SINCE BUT IM NOT SURE. WE WANTED HARDWOOD TO BEGIN WITH BUT WE WERE TOLD WE COULD NOT BECAUSE OF THE CEMENT. WE DID NOT PUT A RADIANT HEATING SYSTEM IN. WE WERE ON A BUDGET.

Stacy, whenever you put a wood or laminate floor over a concrete slab, you will need a vapor barrier to keep the moisture that evaporates from the concrete away from the wood. It can be as simple as using a plastic sheet callled poly (usually 6 mil) or a 2-in-1 underpad which should have that attached to the back.

I am installing a hardwood floor over a slab with radiant heat imbedded in it.I want to lay a 3/4" sub floor, but i don't know the depth or location of the pex in the slab.Can the sub floor be glued to the slab to ensure that i don't puncture the radiant heat components?

I have a garage that has been enclosed to become family room. It has a concrete floor and two sets of concrete steps.

My problem or NOT!

All the hardwood installers are not familiar with radiate heat and state that the suppliers will not warrant the job.

What is your suggestion to get from point A, dead in the water to point B ... HAppy with a warmer room and attractive floors!

Hi Tim,
I am installing a radiant heating system in my house. I was told not to run the tubes under cabinets or in closets. The reason not to run under cabinets was because it would warp the wood, I do not agree, the water temp is not that hot and wouldn't the sun's radiant heat do the same? The reason not to include a closet in a rooms design was the closet is much smaller and would heat up to fast. I feel there would not be as much tubing in the room compaired to the larger room.
Thanks for your help.
Mark

If the radiant heat is disabled for a long period of time (several months for whatever reason) is there the potential for mold to grow between the slab and the vapor barrier?

Thanks.

If the radiant floor heat were turned off (for months at a time for whatever reason), would the concrete be susceptible to mold growth under the vapor barrier?

Hello,

I am hoping you could help us with some questions on radiant heat.

We would like to use this type of heating system in our next home. Friends of ours have heated the slab their home sits on and are very happy with it.

We have the opportunity to relocate an exsisting bungalow to a building lot. The house was built in 1950, has 1.5" tongue and groove under oak hardwood with 6" joists. If we set this onto a heated slab, could we realise enough heat? We live near Ottawa, Ontario, Canada where tempuratures get to -30 during winter.

Many thanks,
