ULTRA-FIN: RADIANT HEATING

Welcome to Ultra-Fin

Ultra-Fin is the leader in cost efﬁcient and high comfort radiant ﬂoor

heating. Ultra-Fin is a hydronic system designed speciﬁcally for

wood-frame housing that is simple to install, and is compatible with

all ﬂoor coverings including carpet, tile, slate and hardwood.

How Ultra-Fin Works

The Ultra-ﬁn system uses ½" (5/8" O.D.) tubing to circulate hot water

through the under-ﬂoor joist spaces, where heat is conducted to

louvered aluminum Ultra-Fins attached to the tubing. The Ultra-Fins

radiate the heat and warm the air in the joist spaces, creating hot air

convection. The heated air warms the ﬂoor uniformly and the ﬂoor

radiates gentle heat throughout the living space above.

What Makes Ultra-Fin Different?

Traditional radiant ﬂoor systems are based on heat contact transfer

technology where hot water tubing makes direct contact with ﬂoor

layers. Compared to Ultra-Fin, these systems are overly complicated,

time-consuming to install, provide lethargic heat response, and

require complicated construction measures such as extra ﬂoor layers

or concrete.

Ultra-Fin creates new efﬁciency by generating hot air convection inside

regular wood-frame ﬂoor systems. By converting the entire ﬂoor system

into a giant heat radiator, Ultra-Fin generates uniform warmth and comfort

at unprecedented cost savings and convenience.

GREAT PERFORMANCE

WITH SIMPLE INSTALLATION

1. HANG THE TUBING

When you install Ultra-Fin, you start by installing the tubing. You can

either run the tubing parallel to the joists using SnakeHangers

™

or you

can drill the joists and run the tubing through the holes.

2. ATTACH THE ULTRA-FINS

You attach the aluminum Ultra-Fins by lapping two ﬁns over a section of

tubing, then inserting two TurnKeys and giving them a 90-degree turn.

Design a Tubing & Fin Layout Drilling Joists Pulling Tubing After you know how much material you need, you are ready to design an installation layout for the tubing and aluminum Ultra-Fins. For standard installation, joists should be drilled 3" below floor sheathing, spaced according to the calculations you made. NOTE: Some sample layouts for High Temp installation are shown on the back of this brochure.
