The width of an internal wall is typically 110mm (approximately 4.3 inches) before plastering. With plaster applied to both sides, the total thickness usually reaches around 150mm (approximately 5.9 inches).
Here's a more detailed breakdown:
-
Basic Construction: Most interior walls are constructed using a single brick "skin," which measures roughly 110mm.
-
Plastering: To achieve a smooth, paintable surface, plaster is applied to both sides of the brick wall. This plaster layer usually adds around 20mm of thickness to each side (or more depending on required finish), increasing the overall width to approximately 150mm.
-
Variations: The wall thickness can vary depending on factors such as:
- Ground Floor Walls: Walls at ground level might be thicker for structural support.
- Ducts and Chimneys: Walls containing pipes, vents, or chimneys will have increased dimensions.
- Soundproofing Requirements: Walls designed for sound isolation might be wider and incorporate sound-dampening materials.
Therefore, while 150mm is a common dimension for plastered internal walls, it's important to remember that thicknesses can vary based on specific building needs.
