Technical Specifications

The Core Design: Practicality Meets Performance

The Cushilay Yellow range focuses on providing a smart, user-friendly solution for home renovations.

• The Top Surface: Features a clean, non-woven fabric surface printed with crisp gridlines to help achieve perfectly straight, clean cuts with minimal material waste during fitting.

• The Core Stability: The 92 kg/m³ density means it doesn't crumble, fray, or tear easily when stretched over carpet grippers, making it incredibly reliable and easy to handle for a seamless DIY or professional installation.

Expert Guidance: Placement & Care

• Where to Fit: Carrying a certified General Domestic rating, Cushilay Yellow 8mm is tailored perfectly for the primary comfort zones of your home. It adds quiet, cozy refinement to Lounges, Dining Rooms, Kids / Playrooms, and Bedrooms. Important: For heavy heavy-traffic stairs and main-runs like corridors and entranceways, a denser 10mm or 11mm contract-grade option from our lineup).

• Installation Tips: This underlay is designed primarily for standard stretch-fit installations using carpet gripper rods. Always lay the underlay with the printed pattern side facing upwards and secure the intersecting seams tightly with heavy-duty carpet tape to maximize thermal seals and prevent shifting.

• Underfloor Heating Warning: Because Cushilay Yellow features a highly efficient, warmth-trapping 2.4 TOG thermal barrier, it is not suitable for use with underfloor heating systems. For heated subfloors, you need the heat to rise freely; pairing this underlay with a standard carpet will exceed the recommended 2.5 TOG safety limit. If you have underfloor heating, we highly recommend switching to a specialised low-TOG option.

Cushilay Yellow 8mm by Ball & Young provides the perfect balance of thermal insulation, acoustic damping, and accessible everyday luxury. By turning subfloor imperfections into a smooth, springy foundation, this premium UK-manufactured underlay transforms any house into a beautifully comforting home.
