What is a cold roof?

with a cold roof, the roof temperature remains the same as the outer air temperature. Cold roofing prevents the formation of ice dams, which can be a regular danger with warm roofs. The ice dams are formed when snow is melted on the roof and then abandoned on the roof. As the snow melts more, the water is caught by ice dams, causing moisture to penetrate the roof into the building, which can lead to structural damage. With cold roofs, because the snow does not melt, there is no doubt about the formation of the ice dam and all the problems that are related to it. The insulation is located horizontally between the attic beams and the floor ceiling. Any gaps in the ceiling are sealed to prevent wet air from the building. The roof rafters are equipped with a pad of a batumen roof that cannot be penetrated with air and humidity.

The space between playgrounds and insulation is ventilated. Warm inner air rises and escapes through the pass holes and the interior space is filled with cold outsidea more air. The temperature between the outer and the interior is soon equal. There is a risk of condensation in these types of cold roofs.

Student roof design with an unprofitable attic space is also available. Here the cold roof insulation is located in the same way as the ventilated cold roof and the ceiling is completely sealed to prevent the humid air from entering the attic space. Polypropylene breathable membrane is used as a roof pad; This allows the inner humid air to be distracted through it, but keeps it out of moisture from leakage inside. There are no holes and moisture in the universe leaves the membrane breath.

The risk of condensation is low in unpleasant cold roofs. However, if the space passes through the water pipes, TZDE may be a chance that they freeze. This problem can be solved by covering the insulation pipe.

6 well beneficial attic space and deprivate the innerMoisture, cold roof reduces winter humidity inside the building. When the weather warms up, the cold roof is useful by keeping the building cool.
