VERT / GREEN
Use siding replacement to inspect structure, air barrier and moisture before covering.
Continuous exterior insulation and thermal bridges
Add continuous insulation without blocking drainage/drying, losing clearances or creating weak details at openings, foundations and eaves.
JAUNE / YELLOW
Thickening the wall moves windows, doors, flashings, meters, outlets and eaves; every interface needs new detailing.
ROUGE / RED
Wet wall, unknown existing drainage or unverified vapour/drying strategy: do not add a very low-permeance layer blindly.

V14
Systems to check before closing the work
V14 connects envelope, air, fire, structure, water and code instead of treating each project in isolation.
V15
Remaining system checks not to miss
V15 covers issues that can block a project, cause a loss or become expensive once concealed.
V19
Edge systems to integrate into the project
V19 covers interfaces that become important when multiple home systems interact.
Building interfaces to diagnose before enclosure or replacement
These tools connect structure, water, air, frost, wind and mechanical systems so repairs do not hide the cause.
V26
Often-overlooked service interfaces
V26 connects systems that cross utility, plumbing, HVAC, envelope and metering boundaries.
V28
Finish and service details to verify
V28 connects small details that become costly once finishes are closed.
