Irma is of Germanic origin, and it is used mainly in the English, French, German, Indian, Italian, and Spanish languages. The name is derived from the short form of German names with the first element irmin (meaning 'whole, immense, universal') or ermen and starting with 'Irm-', such as Irmingard.
Wood framing, or light frame construction, is the assembly of dimensional lumber or engineered wood lumber that is regularly spaced and fastened together with nails to create floor, wall and roof assemblies. Wood is the most common material used within the construction industry today.
The dimensions of the framing, the type of wood the framing is made from, the design of the deck and the weight load on the structure determine the maximum span distances for joists and beams, and understanding how these factors work together will help you to build a safe and secure deck.
