Installing a window on corrugated tin

[kcflhrc]

So we are converting an old lean too building on our property to a chicken coop. It has corrugated tin siding and roofing. I need to install 2 windows on this tin siding. Any recommendations on doing this? I thought I would just frame it on the inside and outside then caulk around it. I really don't see another way to do it.

Thanks

just a suggestion...
They make wooden slats for corrugated metal that allow the corrugations to seat flat...you could possible use it (along with some 1x) to make a better seal for the outside trim around the window...(top and bottom anyway)

Google "windows for corrugated metal". You'll find a lot of ways to do this.

Good luck.

The way I would do it is to run a couple of 2x4's from the ground up on the inside to make the sides of the frame for the window. If you have a dirt floor, be sure to put something under the 2x4's at the bottom.

here are some pictures of available sealing strips:

What type of backing do you have behind the metal? If you have (or construct) a full frame around the window you can use standard metal siding J strips. After you build the framing the correct size for the window, cut out the siding to the frame size, then cut the J strips to size and insert them over the cut edges of metal siding. Next mount the window and pull the J strips hard against the window frame. Put siding screws through the siding and back flat of the J strip and into the window opening frame. Then, if you want it fully weatherproofed, you can caulk between the J Strips and the window.

I know this may sound complex, but it's a very easy installation and will look quite finished.

One other thought. On my window installs in the pole barn, I used a trim piece meant to go over windows and doors (has a drip edge) on the top and the J strips on the sides and bottom.

OK, I found a picture. Not a great one but you can see the top drip edge and J-strips. This is before the siding is installed, but you cut the hole and install the trim, then insert the window without removing the siding.

The windows I bought have a nailing flange already. Not sure how the J strips will work on the corrugated material.

You did say a chicken house right?

My experience:
Pondering:
Find suitable window (I have a bunch of "pulls" from a house remodel, they had moisture between one of the panes). Cost $0
Find where you are going to put it/them. I had a metal angle iron running at waist height I had to go above.
Study a couple of window frame cross sections - pay attention to drip edges.
Find suitable scrap 2x4's.

Piddling/Puttering:
Build frame, cut hole. Put in drip edge.
I've a BUNCH of pieces of Corian sink backsplash pieces about 6" wide. They will NEVER need painting. Excellent drip edge, I just shimmed it to ensure a slight angle so water runs off outside.
Install window.

Seal w/ appropriate flexible sealant - This was the biggest cost, must have spent $10 on sealant and screws.

Put in a little spray foam above & below window in the "bumps" (ridges) in the siding. May not be needed for a chicken house.

BIGGEST problem - deciding on tool(s) to cut siding. Best for me is a combo of HF 14 gauge 4 Amp Heavy Duty Metal Shears and manual tin snips for the bends where the HF's wouldn't do. I tried circular saw, reciprocating saw, jig saw, metal nibbler, just snips, angle grinder and that combo works best for me. Couldn't justify a plasma cutter Yet.

/edit - this was for the apartment in my 40x60 workshop.

Given that these windows have nailing flanges, I would cut the flanges down to a minimum, cut the siding opening slightly oversized and then install the windown and slide the trim in. Of course this depends on how the siding is attached. Any reason not to just remove a panel and then reinstall it?

I have done several of these projects; everyone had different challenges. Provide inside and out side pictures of your building and how tight you want it sealed and I may have a simple solution any DYIer can do, no promises.

This is what I have. The window will be going onto the tin siding to the left of the door. It is a 2'x2' sliding window. If you look close at the first photo you can see my sharpie outline of where the window will be.
