Clad Wood windows are extremely energy efficient. Wood is not a conductor of heat and with the protective cladding on the outside, clad wood windows and doors are very well suited for our desert heat.
The window or door frames can be made out of a variety of wood species. The softwoods include Pine, Mixed Fir or Vertical Grain Douglas Fir. The solid hardwoods include, Alder, Oak, Maple, Cherry, or Mahogany.
