We've still be applying foam to the house, waiting, as per usual, for a dry spell with warm temperatures. Tuesday I put the foam on this crazy triangle wall above the greenhouse and put my 3-dimensional geometry skills to the test.
Here are the criteria I was working with:
- The wall is a triangle
- The foam is 8 inches wide, so I have to take into account the front and back dimensions
- The roof above is at a 5/12 pitch
- The roof above has rafter tails coming through that must be notched for
- The roof of the greenhouse has a compound angle of 22° in the north-south axis and 25° in the east-west axis
- We had to cut out one window opening in the little wall
- I was using funny end pieces of foam that I had to piece together
We started by putting a temporary "roof" on the greenhouse so we had something to stand on.
Then we measured and marked and cut with the wire cutter and dry fit. Miraculously, after the kinks were worked out with the first course, my other pieces fit perfectly on the first go! I was giddily proud.
Then we glued and screwed nailer boards on, all while standing precariously on the compound pitch roof. (My feet and lower legs got sore up there!)
Here's the wall section when all complete:
If your math skills are in need of a little brush up, build something! you don't have to jump right in with a house. Maybe a garden box, a sandbox, a pea shooter for your nephew, a spice rack for the kitchen, or you could get fancy with a tool shed. You'll be so glad you did.
