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 ...
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.
Condensation comes from water vapour within the building. Common sources may include cooking, bathing, dishwashers, etc. The moisture in the air condenses on cold surfaces, sometimes inside the walls called interstitial condensation. Buildings with poorly insulated walls are very prone to this problem.
Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences. DPC visible between concrete foundation and brickwork.
A vapour barrier may be necessary on the inner wall to prevent interstitial condensation. This is often incorporated into the cavity wall insulation system. The spacing of ties is laid down in building regulations , though there may be variations with specialised blocks.
U.S. Surgeon General Dr. Vivek Murthy warned in a recent advisory about alcohol use increasing cancer risk. The advisory notes that alcohol can increase the risk of throat, liver, esophageal ...
Analysis of infrared images can be useful in identifying moisture issues from water intrusion, or interstitial condensation. [12] Other types of anomalies that can be detected are thermal bridging, continuity of insulation and air leakage, however this requires a temperature differential between the inside and outside ambient temperatures.
