System Description

  • The glazing system is screwed to simple rectangular laminated timber or approved
    microlaminated wood (steel or aluminium supports). Special preparation for the support
    profile is therefore unnecessary.
  • GUTMANN LARA GF provides maximum tightness, even in areas of glass with multiple
    divisions.It permits overlapping of the inner mullion-transom seals on four planes at the
    T joint, expanding architects’ and planners’ design freedom.
  • The glass is completely taken up within the profile system. Glass thickness from 9 mm
    to 50 mm are standard.
  • The version of wood add-on construction with 50 mm face width offers further curtain
    wall design possibilities.
  • The GUTMANN LARA GF in different face width – 50 mm, 60 mm and 80 mm – is available.
  • A large selection of sophisticated connection profiles and accessories complete the
    system. Gasket profiles suitable for installation of self-cleaning glasses are standard.
  • The GUTMANN LARA GF system is also available in architectural bronze for particularly
    high architectonic requirements.
