What Is RadiantBoard?

All RadiantBoard aluminum laminated panels are designed to be applied over a subfloor, concrete, or walls and ceilings. The grooved surface creates the pathway into which 1/2″ PEX tubing is placed. When warm water is circulated through the PEX tubing, the heat is transferred to the efficient, fast-responding RadiantBoard, the flooring materials, and then radiated into the heated space providing luxurious heat. It can be used under almost any finished floor covering.

We are excited to introduce a new patent-pending product – Ecowarm RadiantBoard EPS. This new panel features our premium Ecowarm RadiantBoard panel with an insulated layer of EPS foam.

Due to the consistency of our products, both panel types may be used in the same project. Ecowarm RadiantBoard EPS is highly suited to concrete applications such as basements while traditional Ecowarm RadiantBoard is ideal for over-subfloor applications.

Ecowarm RadiantBoard EPS is also suited for wall or ceiling applications. We are happy to offer radiant heating solutions regardless of your project’s size or complexity.

As a major mechanical contractor I have tried almost everything out there, and without a doubt over-subfloor RadiantBoard is the way to go. The hands-on support is the best in the industry. The staff are friendly, professional, highly knowledgeable, and go above and beyond to meet our needs. We’ve completed multiple projects with the RadiantBoard team, and their commitment to building long-term relationships is evident in the consistent quality, passion, and dedication to the success of our projects from beginning to end.

If you’re a general or mechanical contractor looking for a high performing radiant product with world-class support, we strongly recommend Ecowarm RadiantBoard.

Great Match with Hydronic Heat Pumps

Low mass, fast response radiant heat transfer panels are the best match for air-to-water and geothermal water-to-water heat pumps. Find out why…

More contact. Better heat transfer. Excellent efficiency.

Observe the greater contact between tubing and aluminum than other products

Ecowarm RadiantBoard has a patented overbite groove design that gives a larger and tighter surface connection of the tubing to the aluminum resulting in better performance. Good design has a tight, complete connection between the aluminum and the tubing carrying warm water.

Ecowarm Radiant Floor Heating Overbite Design

With our patented overbite design, tough PEX tubing is snapped or whacked into the groove with a small mallet. When warm water flows through the tubing it expands into the space, making a very tight heat transfer connection. The result is excellent performance.

The product you guys make is incredible. I absolutely loved the install process. What you provide is literally a “paint by number”. This is a level of efficiency that is unparalled. Not having hot and cold spots when you’re stepping on and off the tubes underneath the floor, having the conductivity spread out across the aluminum, small boards that are easy to carry on a construction site, the ability to cut the boards with a table saw, and having everything pre-drilled — it’s just incredible. Everything ran without a hitch.

If you’re in the market for radiant heat, I highly recommend looking into Ecowarm RadiantBoard. Maybe the best part is that they are super nice to work with!

I have installed many Ecowarm RadiantBoard projects over the years. They are easier to install than other boards; much less breakage, easier and safer to handle, and easier on saw blades.

How to Buy & Other FAQ’s

Here are some questions that often arise. Feel free to call us any time with any questions!

Yes, but there are conditions where high resistance carpet and pad is installed in a great room with a lot of glass in a very cold climate. Under those rare conditions, the designer will recommend supplemental heat of some sort.

Ecowarm RadiantBoard is typically installed just prior to the installation of finished flooring goods. Store Ecowarm RadiantBoard on the job site in a dry, cool space until it is ready to be installed, in the natural progression of construction.

Yes. Other higher mass concrete type systems have a lot of mass, which may sound good but they have some resistance and more response time issues. Underfloor systems have both high heat transfer resistance and heat loss opportunities resulting in higher operating costs. You want a system close to the flooring goods with high heat transfer characteristics.

Yes, Ecowarm RadiantBoard heats evenly due to the high heat transfer of its aluminum laminate. In a modern home with proper radiant controls, there is no reason to experience a significant temperature difference between radiant tubes.

Aluminum laminate is factory installed in the grooves of the Ecowarm RadiantBoard straight panel, but the super combo panels including curves are made differently as follows:

The super combo boards with curves are first grooved for the tubing using a computerized router. The boards are laminated with the covering layer of aluminum then the grooves are indented and perforated down the middle of the grooves. Combo boards have many perforated grooves to choose from. During installation, the tubing is walked into the chosen grooves splitting the aluminum which then compresses to the side of the tubing.

This results in lower conductivity for ¼ the circumference of the tubing covering in the combo boards (about 35% of the floor surface) It also leaves the conductivity of the aluminum covering unchosen grooves intact. Testing has shown no significant impact on heating efficiency or comfort.

This also significantly lowers manufacturing costs of manufacturing Ecowarm RadiantBoard. The result: the best value in the market.

If your plan has lots of open space and few tight locations, that makes it faster (fewer cuts and fussing). If your installer has some experience, that really helps. So, planning on 250-500 sq ft per day is reasonable with two people.
