I want to install a very thin berber carpet on a radiant heat floor

My tubing runs very close to the walls and I don't want the carpet
installers to nail down the tack strips. I have read that some
basement floor carpet installers will sometimes glue the tack strips
to the concrete, can the same be done for tack strips on my plywood
subfloor?

Yes, it can be done. It will cost more to do that.

If you have plywood as a subfloor, you probably don't need to
glue it. The nails in the tack strips will not go through the
plywood.

It's also unlikely that the radiant tubing runs so close to the
walls. Normally it's held back a few inches and the tack strip is an
inch and a half from the wall.


Well, mine does run 1.5 inches from the wall. Subfloor is also 1/2"
plywood on the radiant panels...which are also plywood.

I'm thinking of gluing the tackstrips myself and using liquid nails?
think that will hold it?

Typically the tubing distance from the wall is 1/2 of the field
spacing. Electric radiant cable runs more closely together, but you
have tubing (hydronic). What sort of radiant do you have that they
ran so close to the wall and why?

I still don't think you have a problem. The tack strip is typically
about 1/4" from the baseboard/wall, the tack strip is about 3/4" to 1
1/4" wide, and the nails are in the middle of the strip. As long as
you can tuck the carpet under the baseboard you're fine. If the room
is large, and you need to stretch the carpet more, then you'll want
the wider tack strip. Other wise the 3/4" will be fine with the thin
Berber. If you haven't installed the baseboard yet, even better.

Gluing will work, and liquid nails will be fine. Make sure you allow
time for a complete cure.

BTW, gluing is permanent, carpet is not. You'll be damaging your
subfloor when you go to change carpets and have to replace some of the
tack strip.
