In Floor Heating

When it comes to getting in floor heating for your home, there are many options. A hydronic in floor heating system is considered the best option because it is energy efficient, providing consistent and uniform heat throughout the space. It also allows for individual room temperature control and can be integrated with a building’s overall heating and cooling system for optimal efficiency. Additionally, as it does not rely on electricity, it can be a good option for off-grid or emergency heating scenarios.


By evenly distributing heat throughout the entire floor area, HYDROFOAM® maximizes radiant insulation for residential projects, creating a more comfortable living and working environment for homeowners.

Nudura continues to innovate in the market with their line of Insulated Concrete Forms, including the introduction of HYDROFOAM®. This product simplifies the installation process of radiant heat insulation, as it is faster and easier to install compared to traditional methods that require multiple steps. The 4’ x 4’ (1.2 m x 1.2 m) boards, which come in 2 1/2” (64 mm) or 4″ (100 mm) thickness, are easily installed with an overlapping interlock on all four sides, ensuring a secure fit during installation. Furthermore, HYDROFOAM® boasts a 360° multi-directional friction fit anchor system for pipe placement, eliminating the need for wire mesh and allowing for easy placement of radiant heat piping in any direction.
