There are a variety of framing materials and systems available in today's building industry. Framing is an important component of building because it must be done in a way that supports the house, protects against the elements, and contributes to the structure's efficiency. A good framing system is one that allows for a higher insulation value to improve thermal efficiency, reduces wood waste (if wood is used), and provides long term protection to a house's structural integrity.
