In-situ foam

from Wikipedia, the free encyclopedia
Cured in-situ foam

In the construction industry - analogous to in-situ concrete - foam is called in- situ foam that is only produced at the installation site. As long as it is liquid, it can flow seamlessly into cavities, adapt to joints or be leveled horizontally. It is only mechanically stable after the curing time. It is in contrast to (hard) foam sheets, elastomer foam tapes and free-flowing polystyrene foam balls, which are delivered ready-made from the factory.

In-situ foams are used for fastening, sealing, heat and sound insulation.

A frequent use for the in-situ foam is the assembly foam for fixing and sealing door and window frames, typically made of polyurethane . Another application for in-situ foams is thermal insulation of double-shell masonry or double-shell wooden walls.

In-situ foams can be organic (plastic, polymer) as well as purely mineral, e.g. B. the magnesium oxychloride cement on-site foam.

In-situ foams are also used in fire protection, e.g. for fire bulkheads, where cables or pipes penetrate walls.
