Barndominium Metal Trim Details | MAD County Standard | Part 15

Alright, guys, welcome back to the show! Today, we're going to talk about the trims on our barndominium. The Mad County Standard is a 2,300 square foot 2-story post frame construction home (39’x36′) and garage (32’x24′) with a wrap around porch. It has a main floor master with a total of 3 bedrooms and 3 1/2 bathrooms. If you're looking to design your own post-frame home or building, email us at design@mrpostframe.com, and we can assist you with that. Now, let's jump into the show and talk about trims and trim details.


L10 Grade Board Trim:

Alright, as we put up trims while waiting for our steel, let's start with the L10 Grade Board Trim. I use this on residential or shop structures. It's an L10 fascia, 10 inches wide, made from a 2x12 grade board. This trim covers the grade board, offering protection and a visually pleasing finish. We create outside and inside corners for easy installation. Once in place, it enhances the appearance of the building, especially when the landscape is brought up to the square base.


Square Base:

Now, moving on to the Square Base trim. This goes at the bottom of the steel, providing a clean finish and preventing anything from going up into the ribs. It's crucial to install this trim level, and we set it with a laser. Whether you have Wainscoting or not, this trim plays a significant role in the overall aesthetics.


Garage Door Trims:

As the team works on the Square Base, I'll discuss the Garage Door Trims. I prefer using sliding door trim for garage door openings. Its design accommodates variations in steel placement, allowing for a cleaner look. I also create corners to simplify the installation process, making it easier to fit the pieces without scratching them.


J Trim and Double Angle:

Next, we have J Trim, which we use around windows and garage doors. Additionally, there's the Double Angle trim, which sits over the Wainscoting and supports the steel above it. This detail ensures a neat finish, especially around garage doors.


FJ Channel:

Moving on to the FJ Channel, it's used at the top of side walls and end walls, where side steel and soffit meet. Its dual functionality makes it a versatile trim, accepting both steel and soffit.


Soffit Detail and Fascia:

Soffit and fascia details

For the soffits, we prefer a flat finish without a bird box at the end. We use L10 trim remnants to create a finishing piece for the triangular area. This not only adds a nice touch but also ensures a color-matched appearance. The fascia completes the look by covering the top of the soffit and creating a clean transition.


Corner Trim:

Around corners, we use specific trims, such as inside corner trim and larger Corners, either four or six inches, depending on the situation. Customization is possible based on the steel placement.


Walk Through Overview:

Hey everyone, I want to take a moment to walk you through the various trims we have for our building in this quick overview. We often receive a lot of questions, especially when it comes to building kits, and things can get a bit confusing. So, let's go through it step by step from bottom to top.

Installing fascia on a barndominium

Starting off, we have a non-standard trim, an L-10 fascia trim that I personally add to our build. It goes under the grade board, extending up the side. Next is our base trim, with the bottom aligned with the interior finish grade of the concrete floor, providing a solid foundation for the side steel.

Moving up, we have the Wayne's coat, usually in a preferred color by our customers. This double angle or Wayne's coat trim slides the steel up and secures the top steel in place. J trim is used around all windows, providing a neat finish. There's an additional double angle for aesthetics and practicality, breaking up the building visually and making it easier to handle.

At the top, we employ an FJ double trim, serving the dual purpose of accepting the steel going up and accommodating the soffit. Corners come in six or four-inch options, and under the porch, the double angle and FJ are used similarly.

Moving to the garage, we incorporate an inside corner between the garage and the house. The trim around the garage doors involves a sliding door trim, allowing customization of jam thickness. This detail, combined with J trim, adds a polished look. Black fascia is chosen here to match black gutters, ensuring any imperfections are hidden.


That wraps up our discussion on trims. If you have any further questions, feel free to leave them in the comments.
