The Premium Floor Solution by Wora Insulation
At Wora Insulation, we believe your home deserves more than just a standard floor. Our Thermo Underlayment is a professional-grade solution specifically engineered for those who demand the highest level of thermal efficiency, quiet comfort, and structural protection for their living spaces.
Designed to outperform standard 3mm (0.12”) underlayments, this advanced thermal barrier is the perfect partner for radiant heating systems and high-end floating floors.

Key Performance Advantages
Superior Thermal Barrier
Engineered for maximum energy retention, Thermo Underlayment acts as a high-efficiency thermal shield. By significantly resisting downward heat loss, it ensures that your radiant heating system works at its peak, directing warmth upward into your home where you need it most.
Advanced Sound Absorption
Experience a library-quiet home environment. Our underlayment is designed to achieve exceptional sound reduction, effectively quieting noise from foot traffic and minimizing the hollow sound often associated with floating floors.
Industrial-Strength Support
Protect the long-term integrity of your flooring’s locking system. Thermo Underlayment is built to withstand massive pressure—up to 13,000 lbs/sq.ft (6.5 t \ m2)—without any loss in volume or thickness over time. This high compression strength prevents the “springy” feel and protects against floor joint failure.
Certified Safety & Moisture Protection
Integrated Moisture Barrier: The closed-cell structure naturally resists water absorption, protecting your subfloor and preventing mold growth. Protect your investment from the ground up with our integrated moisture-blocking film. Thermo Underlayment is specifically designed to guard your floors against harmful subfloor moisture, acting as a permanent barrier that prevents warping or damage. Because the vapor barrier is built-in, no additional films or moisture sheets are required for installation, saving you time and money on every project.

Flame Resistant: Tested and certified to meet high fire safety standards (Euroclass E), providing an extra layer of protection for your household.
