Foil InsideSL1050 Power Plus

Blaugelb Foil InsideSL 1050 Power Plus is the interior-side variant of the DuoSL 1050 sealing foil family, designed specifically for the warm-side seal at window and door connection joints.

What it does

It creates an airtight, vapor-controlled seal on the warm side of the joint, with the fleece-backed face accepting plaster and paint so the install disappears behind the finish. Self-adhesive bonding to typical interior substrates, with full first-minute repositionability.

When and where to use it

• Interior side of window and door connection joints
• New construction and renovation
• High-performance buildings where airtightness on the warm side is critical

• Variable Sd value — adapts to seasonal humidity for safer assemblies
• Fully bonded across the surface for permanent airtightness
