We spend 90% of our time indoors. Yet most homes have poor indoor air quality. The effects - increased risk of asthma and migraines, poisoning from household chemicals, and so on. The solution is simple - good windows with good ventilation. That's where VELUX comes in. Our campaign ''Let your home breathe!'' was created to raise awareness about a problem that no one really knew about. To strengthen the message, we created special OOHs wrapped in plastic.
