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.
Whether the opening is for a door or a window, the framing technique is the same. A header, usually a pair of boards at least 2Ã6 or 2Ã8 sandwiched together, is supported by jack-studs. The jack-studs are fastened to king studs which span the height from the bottom plate to the top plate.
