Skylights and the laws of physics
During wintertime in a Zone 5+ climate, even with good skylights like Velux Skylights (R3/R4). When during wintertime when it’s 20F outside and 68F inside and it’s snowing with a lot of moisture in the air. Every skylight will experience condensation of some sort, correct?
The laws of physics cannot be defied if you have a R-40 roof/attic and then a R3/R4 skylight. When it’s 20F or colder outside and inside the temps are 68F and humidity in the 40% range. Moisture will form on the skylight due to warm moist air rising and condensing on the colder skylight glass, correct?
