What's inside the walls ?

have you ever wonder what´s inside the walls ? our how just a simple thing like Wood can make a complete house stay up for years or decates and still looking pretty ? 

Well in framing we use different types od woods , Not all wood is the same, and since most house frames use wood as the primary component, it's important to learn more about this versatile material. Primarily most of the lumber that's available through either lumber yards or home centers today is graded one or better, two or better or three or better. 

Once the lumber has been purchased, the framing can begin, and it starts with the construction process — the foundation.
There are three basic elements that are joined together to form the skeleton on which the rest of the home will eventually rest

• The sill plate is the first portion of framing that sits right on top of the concrete. That's the part that needs to be drilled for anchor bolts, and it attaches to the concrete foundation. The sill plate on the concrete is usually a pressure treated piece of wood that prevents rot, bug infestation and water damage.
• Once the sill plates have been anchored to the foundation, then you begin to lay out the studs. Studs are what the vertical walls are — the normal walls of the house that are spaced to accommodate windows and doors, where joists sit on top of plates that are on top of the studs.
• If you're framing a floor or ceiling, you'll need horizontal pieces called joists in your house frame. A joist is a horizontal member that sits on top of walls and supports floors or roofing.
