When it comes to finding the best subfloor for heated floors, cork subfloors are the top choice. Genuine cork can provide amazing results for concrete floors, while Eco Cork Foam is designed to deliver incredible performance in any application. There is also an underfloor heating system called QuietWarmth that works perfectly with QuietWalk. This system uses conductive ink strips to disperse heat more evenly and efficiently than metal mesh mats.
FloorMuffler Premium Underlayment has the best sound control ratings on the list, making it number three. It is made of a foam material that leads to a lower R-value and is priced between QuietWalk and Eco Cork Foam. If you're looking to silence noisy foot traffic, look for an acoustic base made of cork or felt. Cork underlayment is also durable, lightweight, easy to install, and the most affordable option. A cork or fibrous material subfloor works well to dampen sound, while a rubber or felt subfloor provides a moisture barrier.
The R-value is an important factor to consider when looking for a subfloor and is even more important when looking for a subfloor compatible with radiant heat. It is always advisable to consult the subfloor manufacturer, as they may have information that we do not know, but from what you have described, it should not be a problem, since it is likely that the vapor barrier is located between the subfloor and the cork subfloor. As an expert in the field of flooring and underlayment, I can confidently say that cork subfloors are the best choice when it comes to heated floors. Not only are they durable and lightweight, but they also provide excellent sound control and insulation. They are also easy to install and are one of the most affordable options available.
Furthermore, cork or fibrous material subfloors work well to dampen sound while rubber or felt subfloors provide a moisture barrier. When selecting an underlayment for heated floors, it's important to consider the R-value of the material. The higher the R-value, the better insulation it will provide. Additionally, it's important to consult with the manufacturer of your chosen underlayment as they may have additional information that could be beneficial in your decision-making process. In conclusion, cork subfloors are the best choice when it comes to heated floors. They provide excellent sound control and insulation while being easy to install and affordable.
When selecting an underlayment for heated floors, make sure to consider the R-value of the material as well as consulting with the manufacturer for additional information.
