Door bottom seal Tesa 05433-101, self-adhesive, brown, 40 mm x 1 m

The Tesa door bottom seal 05433-101 is a self-adhesive sealing strip in brown, 40 mm wide and 1 m long, designed to be fixed to the underside of interior or exterior doors. It provides a continuous seal along the door bottom to reduce drafts, prevent dust ingress, decrease noise transmission and limit heat loss. The product is intended for retrofitting or maintenance of existing doors and is suitable for common domestic and light-commercial door types where a simple adhesive attachment is sufficient.

Advantages

The self-adhesive backing enables tool-free installation and a quick retrofit without the need to remove the door. The 40 mm width covers most standard door gaps while the brown color matches typical wooden and dark-finish doors. The strip creates a uniform contact surface along the threshold which improves thermal insulation and reduces airborne noise. The design is low-profile to avoid obstructing door movement and the material resists everyday wear associated with regular opening and closing.

Suitable for

• Sealing gaps at the bottom of interior doors to reduce drafts
• Improving thermal retention and reducing heat loss through doors
• Minimising dust and small debris entering rooms
• Reducing noise transmission in home or office environments
• Quick renovation tasks where adhesive mounting is preferred

Key specifications

• Width: 40 mm
• Length: 1 m
• Fixing method: self-adhesive backing for direct attachment
• Colour: brown
• Application location: underside of door / door bottom
• Intended use: draft, dust, noise and heat-loss reduction

How to use

Ensure the door underside and threshold area are clean, dry and free of dust, grease or loose paint. Measure and, if necessary, trim the strip to the required length. Peel off the adhesive liner and press the sealing strip firmly along the underside of the door so it forms continuous contact with the floor or threshold when the door is closed. Apply even pressure along the full length to ensure good adhesion. Allow the adhesive to set before subjecting the seal to repeated opening and closing cycles.

Usage recommendations

For best results, apply at room temperature on a well-prepared surface and avoid immediate exposure to heavy moisture. Check door clearance and walk test after installation to confirm the strip does not impede door operation; trim if necessary. For exterior doors with large or uneven thresholds consider complementary threshold plates or adjustable seals.
