Rhombus molding

Rhombus strips made of Siberian larch in three different designs: Bottom: 33 × 56 mm, 15 ° bevel - Center: 26 × 56 mm, 30 ° bevel - Top: 20 × 56mm, 15 ° bevel - (thickness × width)

A rhombus bar is a wooden bar that has a parallelogram cross section . Contrary to the name, the cross-section usually does not form an actual rhombus , which would be a parallelogram with four sides of equal length, also known as a diamond.

Rhombus strips are mainly attached to buildings as external cladding. They are installed in such a way that the sloping side faces up to ensure good water drainage. The thickness of the strips usually ranges from 20 mm to 50 mm, the width from 40 mm to 140 mm. The slope is between 5 ° and 45 °. In practice, an angle of 15 ° to 20 ° is often used. Used normally come wood species which are suitable for outdoor use, ( resistance class 1 to 3) to be able to dispense a coating with oil or varnish.

Modern skirting boards often have the same cross-section and are usually made of simple softwood with a thickness of around 20 mm . However, they are usually not referred to as rhombus strips.
