Research notes

Harbin Opera House combines an expressive public silhouette with the less visible systems that hold and seal its glazing.

Sika credits MAD Architects and places the project in Harbin, Heilongjiang. Its reference identifies two different roles: Sikasil SG-500 CN is a structural-glazing adhesive; Sikasil IG-25 HM Plus is a secondary sealant for insulating-glass units.

These components belong to different joints in a facade assembly. Knowing their names makes the photograph more useful, but does not supply a glass build-up, joint geometry or installation method. The product reference is evidence for those listed uses, rather than a complete facade specification.

What the sources do not establish
  • The supplier reference date is not used as the building completion year.
  • Glass build-ups, joint dimensions and mixing settings are not established.
