At AQ Carpets, we know that choosing the right carpet underlay is every bit as important as choosing the carpet itself — yet it’s one of the most frequently overlooked decisions in any flooring project. While your carpet delivers the comfort, colour, and style, it’s the underlay beneath it that does the hard work — quietly enhancing every aspect of your floor’s performance from the moment it’s laid.
A quality carpet underlay provides far more than just a soft base. It delivers essential thermal insulation that keeps your home warmer and reduces heating bills, effective sound insulation and noise reduction between floors, superior underfoot cushioning and comfort, and — crucially — helps extend the lifespan of your carpet significantly by absorbing the impact of daily foot traffic and preventing premature wear. In short, investing in the right underlay doesn’t just improve how your floor feels — it protects the value of your entire flooring investment for years to come.
A good underlay acts like a shock absorber, reducing wear on the carpet, improving comfort, and even lowering energy bills. It also enhances cleaning efficiency and dampens noise—making your home feel quieter and cozier.

Look at the following key factors to make the right choice for your home:
Material & Comfort: Foam feels plush; rubber feels springy.
Thickness & Density: Thicker (10–12 mm) and dense underlays deliver better bounce-back and insulation—many recommend 11–12 mm for top comfort
Noise Reduction: Felt and rubber excel at muffling footsteps and ambient noise
Thermal Performance: Heat-insulating underlays help cut energy use and cold-floor discomfort
Durability: Crumb rubber and dense combinations maintain their structure in busy areas.
Eco-Friendliness: Felt, recycled PU foam, and crumb rubber reuse materials for sustainability.
Living Room / Bedroom: Opt for plush PU foam or Wool Felt for softness, warmth, and noise dampening.
High-Traffic Areas (Hallways, Stairs): Choose Crumb Rubber for durability and shape retention.
Mixed Zones: Go for Combination underlay (felt + rubber) to balance comfort, support, and noise control.
Underfloor Heating Areas: Use Low-tog underlay to permit efficient warmth transfer.
