How insulated glass units work in a wet, windy place like New Orleans

Two pieces of glass, a dry cavity, and a continuous edge seal make up the insulated glass unit in your window sash.

When that seal is intact, the cavity stays dry and clear, and low-E coatings do their job to cut solar heat.

Between high dew points, frequent rain, and storm loads, the stresses on the IGU seal in New Orleans are relentless.

Understanding Seal Failures

Decoding condensation types so you pick the right fix

A quick sort of condensation types saves you from chasing the wrong repair.

If water beads on the inside pane on chilly mornings, that is interior condensation, usually solved by better ventilation, dehumidification, and improved air sealing.

Moisture on the outside pane during cool nights after hot days is exterior dew, a byproduct of efficient low-E glass radiating heat to the sky, and it is harmless.

Haze inside the cavity tells you the desiccant is saturated and the seal has let in vapor, a one-way street.

What to Do When Igus Fail

Why IGUs give out here

The adhesive systems age under UV and water, and repeated thermal expansion opens a path for vapor.

Gust loads and building movement do not help, especially on wider picture windows.

Units built with dated spacers tend to pump more moisture because the edge runs colder and cycles faster.

Field fixes that do not work, and the ones that do

Venting and washing between panes addresses the symptom, not the failed perimeter, and thermal performance stays compromised.

With good frames, a new IGU drops in and gets you back to spec without a full window replacement.

If the sash is rotted, warped, or the frame leaks, a full unit replacement is the durable route, especially if you want upgrades like impact glass or low-E packages.

Cost Considerations for Window Work

Budgeting the repair or replacement

Expect $200 to $600 for most standard IGUs, while large picture windows, curves, or tints push higher.

If you upgrade to impact-resistant windows for Gulf Coast storm protection New Orleans contractors install, budget in the $1,200 to $2,500 range per opening.
