Cathedral Ceiling – Eliminate Condensation with SPF

Cool roofs made of white EPDM, TPO, or PVC can save energy in hot climates by reflecting more sunlight and absorbing less heat than darker-colored roofs. White membranes, on the other hand, may increase the risk of condensation forming in the roofing system.

The fundamental principles underlying condensation problems with white membranes – particularly in colder, northern climates – are well understood.

Warm, humid air migrates upward during cold weather and infiltrates the roofing assembly through gaps (wall-to-deck), unsealed joints (steel deck end laps), or around penetrations. When moisture in the humid air comes into contact with a surface temperature below the dew point, it begins to condensate. 

This usually happens on the underside of the membrane and can give the appearance of mysterious leaks inside the building. If the vapor migration continues, the longer the surface remains below the dew point, the more condensation will collect.

Cool roofs, due to their reflectivity, frequently fall below – and remain below – the dew point for longer periods of time than darker roofs. The same phenomenon that keeps the roof cool can also make it more prone to condensation and moisture drips, particularly in central and northern climates.

The condensation risk may be efficiently eliminated while the benefits of the cool roof are preserved by a single inch of SOPRA-SPF 202 Spray Polyurethane Foam Isolation (SPF), which is directly applied to the underside of the roof.

SOPRA-SPF 202 is a multifunctional construction material that provides three protection levels – thermal, air, and humidity. An R-value of 6.9 inches is one inch, air-impermeable, and a vapor retarder of class 2. 

SOPRA-SPF 202 adapts to, attaches to, and expands on any surface, form, geometry, and fills the smallest crevices and gaps for a fully monolithic and flawless environmental barrier. SPF 202 may be combined to achieve specified insulation levels in a hybrid movement with an open-cell sprinkler or standard fiber insulation.

Many customers that use fiberglass insulation to insulate the cathedral ceiling have a few unique issues linked with the building of the ceiling.

Heat, humid inside air frequently escapes across the poly barrier and the battle insulation. After contact with the cold surface or cold air, condensation occurs. This condensation may cause battle isolation mold and other moisture issues to influence the underside of the roof, such as decay. Sprayed polyurethane foam supports neither mold nor mildew and simultaneously produces a moisture barrier.

The insulation is eliminated and 2 lb closed cell spray foam is applied in the living room of the house on the bottom of the roof deck that sticks out the warm, wet indoor air. The 2 lb foam is sprayed on the pivot ends, which also stick to the soffit and pivot end.
