Unbeatable Sound Insulation and Durability

This 4.5mm Compressed Rubber Underlay stands out for its superior noise reduction properties, making it an excellent choice for busy households or spaces where sound control is important. Its impact sound insulation is ideal for use under laminate and wood flooring, helping to reduce the transmission of noise through the floor. Whether it's footsteps, furniture movement, or general household noise, this underlay works to create a quieter, more peaceful environment. In addition to its sound-dampening effects, the rubber composition provides lasting durability, ensuring your flooring remains stable and performs well over time. The 4.5mm thickness offers just the right amount of cushioning, contributing to both comfort and longevity.

Perfect for Underfloor Heating and Moisture Protection

Designed with versatility in mind, this underlay is suitable for use with underfloor heating systems, thanks to its low tog rating. This means it allows heat to pass through efficiently, making it an excellent choice if you're looking to add warmth to your home while maintaining energy efficiency. Not only does it work well with underfloor heating, but the integral moisture barrier also adds an extra layer of protection, preventing moisture from rising and damaging your flooring. This feature makes the 4mm Compressed Rubber Underlay a practical and reliable choice, giving you peace of mind in both dry and damp areas.
