Dimensions WSL with a nominal width > mm (or mm) are called continuous weather resistant louvres. Nominal widths with graduation of mm are available. Common heights, see individual louvres page and table page. Sections of to mm are most common. For special cases, nominal dimensions x within maximum sizes are available in any dimension. Continuous WSL louvres are supplied in sections (terminal and intermediate sections). Maximum length of a section = mm, see page and above. Included are: raised countersunk metal screws with slit Ø. x mm. (At site: dowels Ø 7 mm for concrete or brick wall). Special installation situations a) Installation with wall frame b) Installation into wall with outside insulation c) Installation into gas concrete d) Installation without any screws visible Please consult us for additional information!
