4 feet on center?

These two gentlemen are trying to figure out what has kept the roof upright over the years, studs are 4 feet on center on the gable ends

North side gable, living room

South side gable, bedroom and dining room/bedroom

Interesting things happen when you remove the exterior wall, in this case heart of the pine planking, and reveal what is underneath the planking.  Or in some cases what is not under the planking.  In certain sections we had insulation and others we didn't.  Regardless, the batt insulation was being removed as it had been comprised by rain, critters and plants.  Yup plants.  In some areas there were very mature vines that grew between the individual wall planks and seemed to thrive living amongst the Owens Corning.

The plywood sheathing on the house is significant.  It means the attic area has had all the blown celluous insulation removed, studs were added to bring the roof support to every 16" on center, and new open cell foam insulation coats the entire attic roof and gable end exteriors.  5-6 inches thick on the underside of the roof.  This is just a beginning but I had a smile from ear to ear that day.  No more winter days of only getting the temperature up to 58 degrees inside the house.  Bring on winter, I'm ready.

This is the fnished product, sans paint.  Primed Hardyplank covering Tyvek, plywood and open cell insulation in the wall cavities between the studs. 

When the crew spraying the insulation started around the window to the left, dining room/bedromm, we literally had a snow storm in the room.  It was "snowing" foam insulation acroos the room as the gaps and wholes in the wall allowed the foam to enter the house until the foam set up.  A frigging mess but an even bigger smile as I knew we were improving the house and my disposition towards life.

Oliver out.
