Window Condensation: Why It Happens & How to Prevent It

Clear windows don't just look better — they reflect a healthy and efficient home. But when condensation appears on the inside of your glass, it could be a sign of trapped humidity and poor airflow. At Allumondo, we believe that smart design goes hand-in-hand with smart living. Let’s explore what causes window condensation and how you can prevent it.

1. What is Window Condensation?

Condensation occurs when humid indoor air meets a cooler window surface, causing moisture to collect as droplets. It’s common in winter when interior heating contrasts sharply with outdoor temperatures.

✔ Most common in kitchens, bathrooms, or poorly ventilated rooms
✔ Can lead to mold, damage to window frames, and reduced comfort

2. Why Does It Matter?

While some condensation is harmless, persistent moisture can signal larger problems.

✔ Indicates excess indoor humidity
✔ Can damage frames, drywall, and flooring
✔ May reduce energy efficiency and visual clarity

3. How to Prevent It: Allumondo’s Top Recommendations

✔ Ventilate regularly
Open windows or use exhaust fans in bathrooms and kitchens to release trapped moisture.

✔ Use insulated glass systems
Double or triple-glazed windows help maintain warmer glass surfaces and reduce fogging.

✔ Control indoor humidity
A dehumidifier helps maintain optimal levels (30–50%). Avoid drying clothes indoors if possible.

✔ Allow air to circulate
Avoid blocking vents or radiators. Keep blinds slightly open to allow air to flow near glass.

✔ Consider anti-fog coatings
Specialized films or sprays can reduce condensation buildup on frequently affected areas.
