The vacuum autoclave enables impregnation of roof frameworks

I.S.V.E. Srl has recently increased its range of spray impregnators to include the new IMP-PG "Oscillating" model. This vacuum autoclave enables the impregnation of roof framework placed in properly braced packs. The application and use of the IMP-PG is equipped to give wood protection against the following Risk Classes:

- Risk class 1: situation where the wood or wood based product is shielded, completely protected from atmospheric agents and not exposed to humidity.

- Risk class 2: situation where the wood or the wood based product is shielded, completely protected from atmospheric agents, but where high environment humidity may cause occasional but not persistent humidity.

- Risk class 3: situation where the wood or the wood based product is not shielded and is not in contact with the ground. It is continuously exposed to the atmospheric agents or, even though protected from them, is subjected to frequent humidity.

In these three cases, defined by ENC, (European Normalisation Committee), IMP-PG guarantees protection and long lasting esthetical quality of the wood.
