Radiant Floor Heating for Retrofit and Remodeling

Thermalboard is the ideal radiant floor heating solution for remodels

Thermalboard is an excellent solution for radiant floor heating remodeling and retrofit applications. The panel’s 5/8” low profile can be accommodated in most existing structures; it is light weight and easy to cut and is especially cost effective for smaller jobs.

Thermalboard is easy to install by any general contractor following our panel layout and step by step installation manual. Our radiant floor heating provides a very quick responding and efficient solution for comfort and lower energy bills.

Common methods for radiant heat remodeling

Radiant heat remodels can go into a new concrete floor addition, under an existing subfloor or in a thermal panel, like Thermalboard, on top of a subfloor or existing concrete slab. While underfloor staple up radiant systems can resolve issues with existing flooring goods, underfloor systems are far less efficient, respond more slowly and are time consuming to install.

Radiant Heat Retrofit of Existing
Hydronic System

If you have an existing baseboard or other type of system, Thermalboard can be an excellent upgrade solution. Just keep in mind that if you have an existing high temperature radiator or baseboard system, a mixing valve must be installed to lower the temperature entering the Thermalboard radiant section of your system.
