Flat Roof Condensation Risk Analysis

For a flat roof construction be it a cold roof a warm roof or a warm inverted roof the calculation method for year round condensation risk set out in bs en iso 13788 known as the glaser method is almost always sufficient.

Flat roof condensation risk analysis.

A condensation risk analysis is unable to allow for varying standards of workmanship but a high. Flat roofs are among the simplest construction elements that can feature in a building. This type of roof has normally been used over small extensions to dwellings using timber joists and plywood deck. In the above example of a condensation risk analysis the top line t represents temperature and the bottom line d represents the material s predicted dewpoint temperature which varies with the amount of moisture in the air in high humidity conditions a material s dewpoint temperature is increased.

Get an interstitial condensation risk analysis carried out. As long as the roof accords with good practice then a more complex calculation method should not be necessary.
