Flat roof condensation risk analysis.

Get an interstitial condensation risk analysis carried out. A flat roof should be designed to minimise condensation and a condensation risk analysis should be undertaken taking into account positioning of insulating materials vapour control layers ventilation thermal insulation and the choice of materials. 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.

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. This is something we do for all our new roofs as well as part of our design service. This type of roof has normally been used over small extensions to dwellings using timber joists and plywood deck. The analysis will determine the dew point and you can check where the condensation is happening in the report.

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.
