Foil DuoSL1050 Power Plus

Blaugelb Foil DuoSL 1050 Power Plus is a fleece-backed self-regulating sealing foil for the connecting and expansion joints around windows and doors — designed for use either on the inside or outside of the joint.

What it does

A combination of self-regulating plastic film and fleece backing creates a vapor-variable barrier (variable Sd) that is fully bonded across its surface. Watertight against driving rain up to 1050 Pa from the outside, and UV-resistant for at least 4 months. The fleece face accepts plaster and paint, so the foil installs hidden behind the finish.

When and where to use it

• Sealing of window and door connection joints — interior or exterior
• New construction and renovation
• Both warm-side (interior) and weather-side (exterior) installation — eliminates double inventory
