Radiant Floor Heating for Retrofit and Remodeling

Thermalboard Home Graphic

Thermalboard is the retrofit radiant floor heating solution

Thermalboard features a low profile, a high efficiency aluminum surface and sustainable substrate. The standard panel’s 5/8” low profile can be accommodated in most existing structures for retrofit and remodeling; it is lightweight and easy to cut and is effective for smaller jobs.

Thermalboard is easy to install by any general contractor following our panel layout and step by step installation manual. It also provides a very quick responding and efficient solution for comfort and lowers energy bills.

Common methods for retrofit radiant floor heating and 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.
