Nowadays, softwoods and hardwoods both are widely used to make interior and exterior window frames. According to the experts, the best timber for window frames generally relies on some major factors. However, you can consider the following:

  • Due to the dimensional stability and strength, hardwood window frames are properly equipped to bear impact damage. However, specially treated Accoya wood also has high durability and the perfect option for traditional framing.
  • Softwoods are very sustainable and are less expensive than hardwoods. So, if you are in search of economical options, softwood window frames are the way to go.
