Beschreibung
Zusammenfassung:	A PU foam forming composition, dispensed from a single pressurized container and comprising at least 5 %wt of a propellant, may be used for filling the gap between the window frame and the outer perimeter of the glass unit of the window assembly. The PU foam filling is preferably an OCF PU foam and may bring significant improvements to the window assembly, in particular in combination with multiple glazing and/or HR+ glazing, such as improved thermal and acoustic performance, improved air tightness, increased fire resistance, rigidity and burglar resistance. The foam forming composition brings user friendliness during its application as well as when the glass unit needs to be replaced. A corresponding window assembly is also disclosed, wherein the use of the foam filling may allow a smaller window frame for the same glass surface.
