The building envelope matters more than most homeowners realize.
When building a home or addition, people often focus on finishes — flooring, cabinets, paint.
But long-term comfort, efficiency, and durability start right here.
In this case, we used 1-1/2″ ZIP System R-Sheathing.
Why I often recommend it:
✔ Structural sheathing + built-in water barrier in one system
✔ Eliminates the need for traditional house wrap
✔ Continuous R-6 exterior insulation
✔ Reduces thermal bridging through wall studs
✔ Creates a tighter air barrier when properly taped
What that means in real terms:
• Better energy performance
• Fewer drafts
• Reduced moisture risk
• Cleaner install with fewer steps
• Less room for jobsite errors
Yes, it may cost more upfront than traditional sheathing and Tyvek.
But envelope decisions affect everything — HVAC sizing, comfort, long-term efficiency, and durability.
The materials you choose early in a build shape the performance of the entire home.
This is why planning at the structural and envelope stage is so important.
