Flat Roof Condensation Risk Analysis

The analysis will determine the dew point and you can check where the condensation is happening in the report.

Flat roof condensation risk analysis.

This is something we do for all our new roofs as well as part of our design service. Get an interstitial condensation risk analysis carried out. This type of roof has normally been used over small extensions to dwellings using timber joists and plywood deck. 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. 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. As long as the roof accords with good practice then a more complex calculation method should not be necessary. Flat roof refurbishment best.

Get an interstitial condensation risk analysis. Because the waterproofing layer constitutes a vapour control layer on the cold side of the insulation there is a high risk of harmful interstitial and surface condensation on the underside of the deck or the upper surface of the.
