Benefits of Using Ball and Young Underlay
Installing Ball and Young Cosi Underlay beneath your carpet offers far more than additional cushioning.
The APT core technology enhances walking comfort while helping carpets maintain their appearance for longer by reducing compression from daily foot traffic. Better insulation means warmer rooms during winter months, while improved sound absorption helps create a quieter home environment.
Because it is lightweight, installers can position and fit each roll quickly, reducing installation time. Its long-lasting construction and lifetime guarantee also make it a cost-effective investment that protects your carpet while enhancing comfort throughout your home.
Installation Guidelines
Before installation, ensure the subfloor is clean, dry and level. Roll out the underlay with the printed side facing upwards and secure joints using suitable underlay tape.
Trim neatly around walls and obstacles using a sharp utility knife before installing your chosen carpet.
For the best results, pair your underlay with:
- Carpet Tiles
- Carpet Adhesives
