The Steico fix 2.0 – 100 mm wood fiber insulation wedge for window sills offers an effective solution for sealing under window sills. It protects reliably against driving rain and drifting snow. The wedge helps reduce thermal bridges and ensures long-term safety at window connections. It is open to diffusion and ideal for ETICS applications.
Steico designed this insulation wedge to provide a second water-draining level. It solves two key challenges in solid wall construction: energy efficiency and system stability. The hydrophobized wood fiber works together with other Steico components to form a high-performance sealing system.
You can glue the wedge using Steico multi fill. For edge sealing, use Steico Tape F 20/40 or the high-performance black tape with special fleece. Steico offers detailed step-by-step instructions for installation.
This wood fiber insulation wedge for window sills is suitable for all common sill materials, including aluminum, stone, or granite. The product can remain exposed to weather for up to four weeks during construction. However, make sure no water runs under the foil surface.
It features laminated functional film, integrated plastic profile, drip edge, and glass fiber mesh. The slope is 5°, and the dimensions are: projection 100 mm, length 1.35 m, and height at the window base 20 mm. One pack contains 10 pieces.
