EXTERIOR RIGID INSULATION

2" Polyiso rigid board insulation
 
 
Each window gets a 'window buck' or 4" wood frame around it's perimeter to enclose the insulation.  We also pulled up the vapor barrier from the foundation in order to have a continuous barrier from the underside of the slab up to the roof.

 
As with all the insulation, a tight installation and overlapping seams is a must!

 
We had to add a small strip here but will overlap these seams on the final layer.

 
We liked the grey color so much we are thinking about repainting the entire house......yikes!

 
Once the insulation was installed we added the rain screen battens and taped all the frames.  This is where we lap in the first layer of flexible flashing.
