Solid wood doors have been manufactured for many years with the same assembly principle.
In the last few years, the insulation of panels has become a standard step in the manufacturing of doors. The insulation of panels helps eliminate the problems of condensation on the interior of the panels, a location where the panels are the thinnest.
In construction, the R-value is the measurement of a material's capacity to resist heat flow from one side to the other. In simple terms, R-values measure the effectiveness of insulation and a higher number represents more effective insulation. Despite the insulation of panels, the global R value of a solid wood slab door remains relatively low.
In order to create a solid wood slab door with a higher R value, a system for insulating solid wood is herein provided.
