Brickmould Dimension (BD)

Brickmould Dimension Width

The BD width is the measurement of a unit from the outside of the left brickmould to the outside of the right brickmould.

Inswing

Outswing


Brickmould Dimension Height

The BD height is the measurement of a unit from the outside of the head brickmould to the bottom of the sill.

Standard Brickmould is 2” in width, but to determine the brickmould dimension, we cannot add 2” to the unit dimension. The brickmould overlaps the jamb when it is applied to the unit. The overlap differs from inswing to outswing as well so the adder to determine the brickmould dimension is dependent on the swing of the unit.

For an Inswing Unit, the brickmould overlaps the jamb by 3/4″. This means that for each jamb, there is a 1-1/4” adder. The width of the unit has 2 jambs so in order to go from a unit to brickmould dimensions you must add 2-1/2”. The height of the unit only has 1 jamb so to go from a unit to brickmould dimension, you must add 1-1/4”

For an Outswing Unit, the brickmould overlaps the jamb by 1/2″. This means that for each jamb, there is a 1-1/2” adder. The width of the unit has 2 jambs so in order to go from a unit to brickmould dimension, you must add 3”. The height of the unit only has 1 jamb so to go from a unit to brickmould dimension, you must add 1-1/2”

If a larger brickmould or a casing is used, the same overlap will occur, but the adder will change. For example, if a 3” piece of brickmould is used, the adders are as follows:

  • Inswing Unit Dimension Width – 4-1/2”
  • Inswing Unit Dimension Height – 2-1/4”
  • Outswing Unit Dimension Width – 5”
  • Outswing Unit Dimension Height – 2-1/2”

  • The unit sits in the Masonry Opening. Therefore the Brickmould Dimension and the Masonry Opening are related. If you are able to determine one, you are able to determine the other.
