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.

As the foam is clearly visible, it can be applied to targeted areas in head-to-reach areas in roof timbers. After that, the foam disintegrates completely by decomposing into water and oxygen all by itself.


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. The effect is immediate and the dead biomass can be easily removed after just 15 minutes.

Areas of application:
