Services
Foam Carpet Underlay
Foam underlay offers excellent comfort and thermal insulation. Ideal for residential properties, it reduces heat loss while providing a soft underfoot feel. Available in varying densities from 7mm to 12mm thickness, higher density options enhance carpet longevity. This underlay suits most carpet types and is particularly effective for bedrooms and living areas where comfort is prioritized.
Rubber Underlay
Durable rubber underlay provides superior support for high-traffic areas. Its dense composition resists compression, maintaining carpet structure over time. Waffle and sponge varieties offer different firmness levels, with heavier weights (e.g., 150lb) ensuring extended durability. Particularly suitable for commercial spaces or domestic hallways, this underlay enhances acoustic performance while maintaining dimensional stability underfoot.
Underfloor Heating Underlay
Specially designed underlays like Duralay Heatflow facilitate efficient underfloor heating systems. With low tog values, they minimize thermal resistance while maintaining comfort. These products balance heat transfer efficiency with adequate cushioning, ensuring compatibility with both water-based and electric heating systems. Proper selection prevents overheating issues and maintains optimal floor temperature distribution.
Sound Reducing Underlay
High-density underlays such as Heavenly Alpha Gold Label reduce airborne and impact noise. With sound reduction ratings up to 19dB, they enhance acoustic comfort in multi-story buildings. These products combine thickness (11mm+) with specialized foam structures to absorb vibrations, making them ideal for apartments, offices, and rooms requiring noise control near hard flooring transitions.
Premium Quality Underlay
Premium options like Cloud 9 Connoisseur and Silenzia Ultra Quiet combine advanced materials with enhanced performance. Featuring recycled content and extended warranties, these underlays offer superior comfort, noise reduction, and thermal efficiency. Designed for discerning customers seeking long-term value, they maintain pile resilience in high-end carpets while supporting sustainability goals through eco-friendly manufacturing processes.
