Frost or condensation buildup in the window—a little is to be expected, but entire window panes covered in ice or moisture could mean a draft. Detection Methods
Condensation on a window during a rain shower. Condensation in building construction is an unwanted phenomenon as it may cause dampness, mold health issues, wood rot, corrosion, weakening of mortar and masonry walls, and energy penalties due to increased heat transfer. To alleviate these issues, the indoor air humidity needs to be lowered, or ...
It often causes damage similar to damp in a building and often appears in similar places. This is because it occurs in the "dead air" pockets that accumulate in both horizontal and vertical corners (i.e. out of circulating air patterns). Mould growth caused by condensation in dead air pocket behind books
Reduced heat flow also helps prevent condensation [3] [4] [5] which is triggered when the temperature of the inside surface falls below the dew point. Assuming an outside temperature of 0 °C with wind velocity 7 m/s (15 mph; 24 km/h) and inside temperature 20 °C condensation occurs at only 30%RH relative humidity with a single-glazed system ...

A vapor barrier (or vapour barrier) is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling, or roof assemblies of buildings and of packaging to prevent interstitial condensation.
Interstitial condensation is a type of condensation that may occur within an enclosed wall, roof or floor cavity structure, which can create dampening. When moisture-laden air at dew point temperature penetrates inside a cavity of the structure, it condenses into liquid water on that surface. The moisture laden air can penetrate into hidden ...
“High humidity can also create condensation along the base,” he says. “If this moisture build-up doesn’t dry out within 24-48 hours, there’s an opportunity for microbial growth.”
