pivotpivoting with central axisPA

Product

• Series: TGL ISO — 24 BT 50 / 32 BT 60 / 44 BT 70

Design description

• Designed for vertical façade installation
• Frame and louvre blade profiles: aluminium with thermally insulated composite using PA6.6 profiles
• Filling: 2‑glazing or panel; framed glazing all around
• Oscillating louvre blades mounted on a horizontal pivot

Profile dimensions

• Overall frame depth: 50 mm
• Frame face width: 38 mm
• Vertical blade face width: 33 mm

Type of opening

• Louvre windows consist of one or several superimposed blades that pivot on a horizontal axis as an oscillating wing. The lower portion opens outward below the pivot axis and the upper portion opens inward. Pivot axis is normally centered but can be offset up to 1/3–2/3 if required.
• Standard opening angle: 78°; adjustable 0–90° if required

Gaskets

• Vertical: brush seal
• Horizontal profile joint: brush seal + EPDM

Fittings

• Concealed fittings
• Made of corrosion‑resistant materials; galvanized

Surfaces / Finishes

• Profiles anodized; powder or wet paint coatings available per RAL, NCS, DB
• Special colours available on request
