Radiant Floor Heat Insulation: More Comfort, Less Energy Waste

In-floor heating insulation isn’t just an upgrade; it’s essential for getting the most out of your radiant floor heating. Whether you’re planning a spa-style bathroom, modern kitchen, or open-concept living space, insulation for heated floors keeps warmth moving upward, not lost into the subfloor. That means more comfort, less waste, and better performance from your system.

These radiant floor heating insulation layers reduce heat loss beneath your floor, speeding up warm-up times and lowering energy bills. Thoughtfully designed for both electric and hydronic systems, our in-floor heat insulation fits neatly beneath cables, mats, or pipes, without adding unwanted bulk. Plus, it pairs perfectly with tile, vinyl, engineered wood, and more.

If you want radiant warmth that’s responsive, efficient, and built for the long haul, heated floor insulation isn’t optional; it’s foundational.

Why Floor Heating Insulation Makes a Big Difference?

Faster Warm-Up Times - Insulation reduces heat loss to to subfloors, allowing your heating system to warm the room more quickly and efficiently—so you feel the comfort sooner.
Improved Energy Efficiency - By directing more heat upward where it's needed, insulation reduces wasted energy, leading to lower utility bills and more environmentally friendly operation.
Thin, Lightweight & Easy-to-Install - Synthetic cork insulation is lightweight, easy to cut, and adds minimal height. Making it the ideal labor-saving alternative to backer board.
Ideal for Concrete or Cold Subfloors - Concrete and slab floors naturally absorb heat. Installing insulation helps block that thermal loss, making it especially beneficial in basements, garages, or ground-level rooms.
Moisture-Resistant and Mold-Proof – Unlike natural materials, synthetic cork won’t rot, warp, or degrade over time, making it an ideal insulation layer for bathrooms, basements, and other moisture-prone areas.
