Fenestration Water Testing
Certified field water testing to CSA A440.4 and ASTM E1105 — from the team that helped develop the standard.
Fenestration water testing applies calibrated water spray to windows, doors and glazing while inducing a pressure difference, to see whether water penetrates beyond the interior plane. It's how you diagnose a suspected leak, validate new installations, or meet warranty and commissioning requirements.
Our engineers contributed directly to the new CSA A440 in-field testing standard, and presented our field methodology at WinDoor 2022. For more than five years we've tested hundreds of units across residential towers, commercial buildings, heritage retrofits and custom homes.
