Brick Mould Sizes and Profiles for PVC Door Frames

Choosing the right brick mould for a PVC door frame involves more than simply looking at the Face Width. Profile Depth, Back Profile, Jamb Depth, overlap and stock length all affect the final fit. For door manufacturers and distributors, the difficulty is knowing what that size measures. Overall Width, Profile Depth, Face Width, Back Profile, Jamb Depth, overlap and stock length answer different questions. Once those dimensions are separated, a trim choice becomes easier to explain, repeat and check across a production run.

What a brick mould size actually measures

Brick mould forms the exterior border where the door frame meets the surrounding wall finish. It can meet brick, stucco or siding. The name describes its role as trim; it does not mean the moulding is made from brick. With PVC exterior door casing, Overall Width describes the full width of the profile, while Face Width refers specifically to the visible front face when that dimension is separately specified.

A two-inch Overall Width is a common option, but it is only one measurement. Profile Depth determines how far the section projects. Back Profile determines how the section sits against the adjoining surfaces. A flat Back Profile and a notched Back Profile may have the same Overall Width while meeting a stepped wall edge differently.

Each measurement needs a named reference point. A drawing should distinguish the full section from a local lip or recess. For wholesale listings, keeping those labels beside the model number helps prevent a familiar size from being mistaken for a complete fit specification.

Flat and notched backs change the fit

The Back Profile matters wherever the trim meets a change in surface level. A flat bearing surface needs suitable support, while a back relief can accommodate a particular step. That is why matching the Back Profile is as important as matching the Overall Width.

For this interface, Xinhong New Materials offers MCN-016 Flat Brickmould alongside MCN-006 Notched Back Brickmould. Both have a 2-inch Overall Width, so the useful comparison is how their Back Profiles meet the frame and wall. The flat option is part of the coordinated trim selection for our PVC jambs.

For MCN-016, the 2-inch Overall Width equals 50.80 mm, while the 1.25-inch Profile Depth equals 31.75 mm. They describe the component, not the finished opening. The back relief on MCN-006 also needs a full section check: its outer depth cannot be used as a substitute for the depth of the recess itself.

Jamb Depth sets the meeting point

The jamb brings the frame through the wall depth, while the brick mould finishes the exterior edge. A wider jamb does not automatically require a wider brick mould. The deciding issue is where the jamb ends relative to the cladding and how much space remains for the trim to bear and overlap.

This makes PVC door frame size a separate selection from the brick mould’s Overall Width and Face Width. The MCN-001 has a Jamb Depth of 4-9/16 inches (4.563 inches / 115.90 mm), while the MCN-003 has a Jamb Depth of 6-9/16 inches (6.563 inches / 166.70 mm). Each must match the actual wall build-up.

The two jamb options can therefore share a two-inch trim concept without sharing every installation detail. Check the exterior meeting point with the actual profile pair. If the jamb sits too far forward or back, extra Face Width alone will not create a properly supported joint.

Overlap determines the outside trim dimension

The outside brick mould dimension includes only the part of each side trim that extends beyond the frame. Some Face Width sits over the jamb. Adding two full trim widths to a Marco de puerta de PVC therefore overestimates the finished width whenever the trim overlaps the frame.

An illustrative calculation makes the distinction clear. Assume a frame is 36 inches wide, each brick mould has a 2-inch Overall Width, and each overlaps the frame by 0.75 inch. The projection beyond each side is 1.25 inches. The outside trim width is then 36 + 1.25 + 1.25 = 38.5 inches.

That example is geometry, not a universal allowance for our profiles. The actual overlap depends on the assembly, including its swing and reveal. Height also needs its own reference points: the head trim and sill are different boundaries. Confirm the finished outside width and height before matching the assembly to the exterior opening.

Stock length affects the cutting plan

Stock length answers how the selected profile becomes side and head pieces. The brick mould range includes 84, 101, 168 and 192-inch length categories. Confirm availability for the chosen model and finish, then calculate cuts from the assembled dimensions rather than the nominal door leaf size.

A cutting plan needs room for mitres, saw kerf and end trimming. Temperature movement needs separate treatment at installation. PVC trim expands and contracts as temperature changes, so a tight sample fit does not establish the correct allowance for every site. Use the applicable profile installation instructions for joint and fastening details.

A complete fit needs more than Face Width

A repeatable brick mould choice combines the visible width, rear shape, jamb meeting point and finished outside dimensions. Stock length follows from that geometry. For a door production programme, confirming those relationships on the actual assembly gives distributors a clearer basis for matching trim across orders.

Our Flat Brickmould and PVC jamb options can be considered together when checking the exterior transition for your door range.

Preguntas frecuentes

Does a flat back mean a completely plain face?

No. Back shape and visible face detail are separate features. MCN-016 combines a flat rear surface with moulded detail on its exposed face.

Does a deeper jamb need wider brick mould?

Not automatically. Jamb Depth follows the wall build-up. Brick mould width follows the exterior coverage and overlap needed at the meeting point.

Is brick mould the same as a threshold?

No. Brick mould finishes the exterior perimeter at the sides and head. The threshold is at the bottom of the doorway and needs its own dimensional check.
