Staple-up Installation Manual

Ceiling Installation Manual
Ceiling installation manual
Installing tubing in the ceiling used to be a very common method for installing radiant heat and is an excellent way to add comfort to any space if you don’t have access to the floor. This also works as a good supplement if the floor heat cannot entirely heat an area.
Wall Installation Manual

Retrofit into floor joists
A nearly finished installation may look something like this

The Staple-up system is the most common way to add radiant to any structure, new or old. With the staple-up system, aluminum heat emission fins are used to hold the radiant heating tubing up against the bottom of the sub-floor. A reflective barrier and insulation is then installed below this so that all of the heat goes in the direction that you want which is up into the room above.

If you can see your joists from the floor below, then you can enjoy all of the benefits of radiant heat by installing a “Staple-Up” system. If you utilize your water heater as the heating source, you now have a system that is SOLAR COMPATIBLE! Click here to learn more about that option.
