Closing Top of Corner Trims

Closing Top of Corner Trims

I am so enjoying Hansen Pole Buildings’ client RYAN in ELLENSBURG. Ryan has been assembling his own new post frame building and really cares about his end result. He asks good questions, open to advice and doing a very nice assembly.

Ryan recently wrote:

“I’m working on putting all the corner trim on the building, but I’m not quite sure how to install the corner trim that installs under the wind girt on the side sheds to ensure that any water flowing down the front/rear endwalls will flow over the corner trim and not be able to get behind it. Can you give me any pointers for this piece?”

Ryan’s challenge will be same as standard corner trims when applied below enclosed level return soffits (as in photo above). Top end of corner trim isn’t sealed against building walls.

To best of our knowledge all of our clients with a similar detail have ignored it. There are some options…

Easiest – fill “gap” with a Polyurethane spray foam such as Great Stuff™ (https://www.greatstuff.dupont.com/?msclkid=59bda31e7bdb1d55c71ef8b1966c30ee). Key to success, use a closed cell foam, hence polyurethane.

Next easiest – we have an expanding closed cell foam sealant in 13′ long rolls. When unrolled it expands to 1″ square.  Read more information about it here: https://www.hansenpolebuildings.com/2016/03/emseal-self-expanding-sealant-tape-closures/.

Most difficult – top edge of corner trim can be cut back 3/4″ along bends for wide faces, folded back to fill space and custom cut to fit around any steel high ribs. Tab edges need to be sealed against siding with caulking. I am really good with cutting steel trims and I am unsure if I would attempt this myself.

This concluded my response to Ryan.

Up sprouted a self-challenge – if I was going to pick most difficult choice above, how would I go about doing it? Out came my graph paper, resulting in:


First, cut ¾” down length of corner trim along each bend. Next, fold over Tabs 1 and 2. Tab 3 and 4 are folded over next with “out of plane” triangular portion being cut from each. Cut top ¾” from each hemmed flange. Place liberal amounts of caulking between each tab overlap.

Sometimes There Are Just Not Words: Hansen Building Disaster

Sometimes There Are Just Not Words to Express…  Building Disaster

How horrifically a build can be botched.


In a scene from 2013’s box office flop The Lone Ranger – Tonto (played by Johnny Depp) and the Lone Ranger (played by Armie Hammer) the heroes get themselves buried in the sand up to their necks. After looking at the photos provided by our client of what a “professional” builder did in framing his building, I am thinking tossing a coin to decide the builder’s fate might be appropriate. Heads – buried in the desert to the neck, or tails – boiled in scalding safflower oil (as we would not want the builder to meet his demise due to saturated fats).

These photos are of the front endwall of a Hansen building. The areas where the OSB (Oriented Strand Board) are visible are shearwalls. These are needed in order to carry the horizontal loads imposed on the building due to wind from the roof to the ground. In most cases, the steel siding is adequate to carry these loads. In this particular case, a large endwall door opening precludes this as a design solution.

In order to function as a shearwall the OSB has to be nailed on all edges, hence the 2×6 which is visible on the face of the columns. The engineered plans for this building happen to show the verticals as being 2×4, however this did not stop the builder from hacking up 2×6 which was ordained for somewhere else on the building. The trick to attaching the OSB at the edges (next to the columns) is to mount the provided 2×4 half onto the column, the other half projecting past the column so the OSB can nail to it.

Oops – ignored this part of the plan (and obviously never opened the Hansen Pole Buildings’ Construction Manual where this assembly is shown in step-by-step fashion).

But wait, it gets even better (or worse for the poor building owner)! Stay tuned tomorrow for the next installment .
