Exterior sealant joints are expected to remain intact for 15–20 years while withstanding
building movement, temperature extremes, UV radiation, bulk water exposure, and pressure differentials. One of the most underappreciated components in meeting that standard is the closed-cell foam backer rod. When backer rod is omitted or improperly installed, movement stressors — building settling, thermal cycling, and material temperature differential — become leading contributors to premature adhesive or cohesive sealant failures.

A Case for EMIS: Why Granular Building Data is Worth the Effort
By Riaz Hoque on May 13, 2026 8:00:01 AM
Energy Management Information Systems (EMIS) continuously monitor equipment/system performance, establish normalized baselines for how equipment should operate, track whether corrective actions persist over time, and detect when something begins to drift. Think of it as a fitness tracker for your building - one that learns what "normal" looks like and alerts operators when something changes.
