A thoroughly well thought-out solution.

JATI DSS Roof Timber Foam

A quarter of an hour is not long. But it is long enough to safely kill mould, spores and bacteria in infested roof timber. JATI DSS Roof Timber Foam was specifically developed for this application. It is both consistent in terms of results and flexible in terms of applications.

The foaming power can be individually adjusted with the foaming additive that is included depending on the requirements or the type of surface on which JATI DSS Roof Timber Foam is to be used. Either way, the foam disintegrates automatically and leaves no harmful disinfectant residues.


Less creates more.

You can apply JATI DSS Roof Timber Foam over an extensive area with a foaming device and also press it into joints or cracks. At 150 to 200 ml/m2 (depending on the surface quality), the consumption rate of JATI DSS Roof Timber Foam is extremely low. As the foam is clearly visible, it can be applied to targeted areas in head-to-reach areas in roof timbers. The effect is immediate and the dead biomass can be easily removed after just 15 minutes.

Areas of application:
