How Do You Make the Best Even Better?

Since 2014, Earthmother XPS Board has earned the trust of countless households.

So reliable, in fact, that many came to believe this was simply how underfloor heating insulation should be.

But we never stopped asking questions.

Could we retain more warmth within the same limited space?
Could we reduce energy consumption and increase load-bearing strength—without adding thickness?
How do you make the best… even better?

Today, we proudly present our answer:

Earthmother XPS Board PRO

Stronger. Insulation and load-bearing performance rise together.
Slimmer. Extreme compression of thickness, giving vertical space back to life.
Greener. Stricter standards for a healthier, more reassuring living environment.

XPS Board PRO is a milestone beyond XPS Board.

Empowering what you can’t see—and freeing what you can.

030 Grade — Redefining Thermal Conductivity

We’ve reduced the thermal conductivity from 0.034 W/(m·K) in XPS Board to an impressive 0.030 W/(m·K) in XPS Board PRO. Lower conductivity means better insulation. At the same 20 mm thickness, XPS Board PRO delivers a 15.5% increase in thermal resistance:

XPS Board: 0.58 m²·K/W

XPS Board PRO: 0.67 m²·K/W

In practical terms, this means more heat stays where it belongs—beneath your feet, warming the people you love most.

Every Bit of Heat, Fully Utilized

Better insulation naturally leads to lower energy consumption.

Using ANSYS thermal simulation, we conducted rigorous performance modeling. The results show that XPS Board PRO significantly reduces downward heat loss while maximizing upward heat transfer—ensuring warmth is delivered to the room, not wasted below.

What does this mean for your home?

Under specific operating conditions, for a 100 m² heating area, XPS Board PRO can save approximately

57.88 m³ of natural gas per heating season.

Spend a little more once. Save for years to come.

From day one, it starts paying back.

30 Tons of Strength, Rock-Solid Stability

With a compressive strength of ≥300 kPa, XPS Board PRO can withstand up to 30 tons per square meter.

Heavy cement screed.
Solid hardwood furniture.
Even a child’s grand piano.

No matter how life changes, your floor remains flat, stable, and uncompromised—without deformation or collapse.

Enjoy the confidence of solid ground beneath you.
The rest is taken care of.

Slim by Design. Powerful by Nature

Traditionally, better insulation means thicker layers—and less living space.

XPS Board PRO breaks that compromise.

At a standard thickness of just 20 mm, it delivers enhanced thermal performance, preserving every precious centimeter of floor height.

You no longer have to choose between warmth and space.

With XPS Board PRO, you can have both.

Pure by Instinct

Sustainability is not an option—it’s our baseline.

XPS Board PRO is manufactured exclusively with crystal-grade virgin material, completely free from impurities and recycled fillers. Combined with Earthmother’s in-house developed eco-friendly mixed foaming agents, every board passes stringent testing by the National Building Materials Testing Center.

Non-toxic. Odor-free. Safe.

Though hidden beneath the floor, the peace of mind it brings is something you can feel with every breath.

XPS Board PRO — Strength, Hidden Beneath the Surface

From 0.034 to 0.030, we didn’t just improve a number.

We pushed the limits of technology—and redefined comfort.

Stronger insulation.
More stable support.
Cleaner materials.

Everything you imagine about underfloor heating insulation becomes reality here.

Because in the end, experience is the true measure.

Stronger than ever. Warmer than ever.

That’s what makes it PRO.
