Cushioning and Comfort: It provides a soft, springy base, making the floor more comfortable and softer to walk on and reducing foot fatigue.
Noise Reduction (Acoustic Barrier): It absorbs sound, reducing both the noise of footsteps (impact noise) within the room and the sound transmission to the rooms or floors below.
Insulation and Energy Efficiency: It acts as a thermal barrier, helping to retain heat and prevent cold from seeping through the subfloor, which can lower heating costs.
Protection and Longevity: By absorbing the shock of foot traffic and pressure, it reduces wear and tear on the final flooring material, significantly extending its lifespan.
