In Floor Heating Tube Tied To The Rebar

Now it is time to place our rebar and welded wire.

In floor heating tube tied to the rebar.

This is also when we place our manifold. Added protection from future tube damage. This will allow the even attachment of pex later. Staple nail and screw down clips allow the installer to hold tubing to wood floors joists and studs.

The insulation phase is crucial for a radiant floor. 20mm underfloor heating pipe installed on a142 mesh quickly. This size is adequate for all small to medium size jobs both in residential and commercial projects. 1 2 oxygen barrier pex is the most popular size used for radiant floor heating in both thick and thin slabs.

Mainly heated slabs radiate outward rather than downward so insulation on the edges of the slab is most important. And since they are clips they allow the tubing to be repositioned for better coverage. Once the rebar is in place the wire is zip tied over. The compacted aggregate base is first followed by a 6 mil polyethylene vapor barrier then insulation then rebar or wire mesh or both.

It also helps to reduce fatigue. In this application structural rebar was required and welded wire 6x6 inch square will be placed as a grid on top. 5 8 barrier pex can be used for larger projects where high btu load is present due to lack of proper insulation larger than normal slab thickness or special project considerations.
