PRODUCT DESCRIPTION:

When tubing is attached to the underside of the sub-floor, this is known as a below-deck or joist-space dry system. These systems don’t affect floor height nor do they disrupt existing floor coverings, making them ideal for retrofit projects. Under-floor staple up is also ideal for adding ‘floor warming’ to spot areas in existing rooms.

 

Because the heat has to travel further to warm the room, below-floor systems usually require higher water temperature to perform as well as above-floor systems. Installing reflective insulation under the tubes will help direct the heat upward. Between Joist Insulation offers two pure reflective facings for maximum reflectivity, plus flattened flanges on either side for easy stapling to joist frames. The end result is lower energy costs and increased comfort to the home owner.

 

INSTALLATION METHOD 1:

1) Unroll & staple reflective Double Bubble reflective across the floor joists.
2) Seal joints & perimeter with FOIL Tape (3” wide).

 

INSTALLATION METHOD 2 & 3:

1) Using 16” wide reflective Double Bubble reflective with Staple Tabs.
Insert material between the joists to 2” to 4” below heating coils, or as recommended by manufacturer instructions.
2) Staple into joists.
3) Seal ends using Foil.
4) *Install drywall if desired, per Method #3.
