Hoya Ondol panels are several times lighter than the wet method. This allows for use in weaker or historic buildings. It also facilitates installation on higher floors and reduces transportation costs.
Dry Method

12-17 kg/m²
Hoya Ondol panels are several times lighter than the wet method. This allows for use in weaker or historic buildings. It also facilitates installation on higher floors and reduces transportation costs.
Hoya Ondol panels are stronger/harder than the concrete commonly used in wet concrete screeds for underfloor heating.
Dry Method
(Hoya Ondol Panels)
34.5 MPa
Hoya Ondol panels are stronger/harder than the concrete commonly used in wet concrete screeds for underfloor heating.

(required concrete curing)
2 days
(immediately ready for use)
Hoya Ondol panels are much faster to install, mainly due to the lack of the need for preparation, pouring, and curing of concrete.
