At Radiant Underlay, we are passionate about providing the highest quality carpet underlay to our customers installing underfloor heating systems. With over 25 years of experience in the construction industry, we are dedicated to helping our customers achieve thermal comfort and energy efficiency in their homes.  Our product is specially designed to ensure maximum heat transfer through carpeted surfaces, making it the ideal choice for homes with 'in-slab' underfloor heating systems.

​

Our products are designed to provide complete comfort and peace of mind, with the highest loft rating and lowest Tog rating combined. This ensures that your heating system is operating to its maximum efficiency, while providing the most luxurious feel possible.

​

We are confident that our product is the best in the market and pride ourselves on our commitment to seeing housing standards raised in New Zealand.
