How To Do Thick Exterior Insulation

On the Build Show today, we apply a thick exterior insulation blanket to optimize energy efficiency and durability for this home. Using two layers of Atlas Energy Shield XL polyiso insulation over ZIP System sheathing, we demonstrate each step of this process, ensuring a continuous R-20 insulation layer that significantly reduces thermal bridging.
For added energy efficiency, the silver aluminum facer of the polyiso panels faces outward on the rain screen side, providing a radiant barrier effect in hot climates like ours. Get a firsthand look at how to maximize both comfort and durability with expert insulation techniques!
