Brickmould: J-channel vs Flange

 

Brickmold is a casing for exterior doors. It abuts the building’s exterior facing material and serves as a barrier between the siding and the frame.

Brickmould with Flange

Brickmould with a flange allows for easy flashing and moisture protection. After installing the unit, you can nail through the flanges as a temporary hold then place flashing tape followed by the exterior material over the flange creating a good weather seal.

Brickmould with J-Channel

Brickmould with a j-channel hides the cut edge of exterior material and takes the place of a separate j-channel around the brickmould. Using brickmould with a j-channel also allows the exterior material to expand and contract.
