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 size of wood framing members is standard regardless of species and is typically stocked at lumber yards in nominal widths of 2 to 12 inches, increasing in 2 inch increments. Pre-cut lengths of lumber start at 4 feet long and, increasing by 2 foot increments, can be found up to 24 feet long. Nominal thickness may be 1 inch, 2 inch, 4 inch, 6 inch or 8 inch.
