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.
Plywood, for example, can be attached to either side of the floor joist effectively sandwiching the original floor joist. Normally, however, standard framing lumber is used, such as 2Ã10âs or 2Ã12âs or whatever the original floor joist material is constructed out of. In some cases steel or engineered lumber is used.
