Insulating process for existing structures badly insulated consists on making holes in the walls to fit fireproof panels in and then complete the casing with additional panels

摘要

Insulating process consists on surrounding the technical shaft with fireproof panels (24-31). First vertical apertures are made in each adjacent wall so that fireproof panels (24-27) can be fitted in the wall. The existing panels are then joined one to the other by additional panels (28-31). The fireproof panels have apertures to allow access to the inside of the technical shaft.
