Why Do You Need Underlay for Carpet?

Carpet underlay isn’t just an optional extra, it's a crucial part of your flooring system. Here's why:

Comfort: Underlay adds a cushioned layer beneath your carpet, absorbing impacts and making it softer and more luxurious to walk on.

Insulation: Quality underlay improves heat retention, keeping your home warmer and more energy-efficient.

Noise Reduction: It reduces footstep sounds and overall noise, especially in multi-storey homes.

Carpet Longevity: By absorbing impact, underlay protects carpet fibres and helps maintain your carpet’s appearance for years to come.

Better Finish: A quality underlay can help smooth out bumps in the sub-floor, resulting in a flatter and more consistent finish
