Gap seals for sliding doors – protection against drafts, dust & energy loss
Gap seals for sliding doors are essential when it comes to ensuring comfort, energy efficiency, and longevity. Sliding doors are practical and space-saving, but due to their design, they tend to have gaps between the door leaf and frame. These gaps can let in drafts, dust, moisture, and noise. High-quality gap seals reliably close these gaps and ensure a pleasant indoor climate – both in private homes and in industrial and logistics applications.
Why gap seals are essential
Without sealing, sliding doors are weak points in the building envelope. Cold air penetrates through open gaps, warm air escapes, and heating costs rise. Dust, insects, and moisture can penetrate unhindered, while outside noise is barely reduced. Gap seals provide a solution: They seal the gaps and ensure security, comfort, and efficiency.
Structure & technology of modern gap seals
Modern seals are made of high-quality materials such as EPDM, silicone, or rubber. Brush profiles are often used, which flexibly fit the door leaf and frame. Magnetic systems that close the gap seamlessly are particularly effective. Adapter strips are available for non-magnetic surfaces, facilitating installation and ensuring secure fastening.
- Lip seals: flexible sealing against drafts and moisture.
- Brush seals: ideal for dust, dirt and insects.
- Magnetic systems: maximum tightness for industry and private use.
- Adapter tape: Solution for non-magnetic surfaces.
Advantages of high-quality gap seals
- Energy saving: prevents heat loss and reduces heating costs.
- Soundproofing: reduces disturbing noises from outside.
- Moisture protection: no penetration of rain or condensation.
- Cleanliness: blocks dust, pollen and insects.
- Durability: protects the door system from wear.
Areas of application
Gap seals are versatile and can be used in many areas:
- Living area: patio and balcony doors, interior sliding doors.
- Industry: Hall and logistics sliding doors with high loads.
- Commercial: Sliding doors in hotels, offices and public buildings.
- Modernization: Retrofitting existing sliding doors.
Technology & Standards
In order for gap seals to function reliably, they must comply with applicable standards:
- EN 12365: Requirements for seals for doors and windows.
- DIN 4109: Standard for sound insulation in building construction.
- DIN EN 12150: Safety requirements for glass doors (relevant for glass sliding doors).
Assembly & Installation
The installation of gap seals is simple but requires precision:
- Clean the surface thoroughly.
- Cut the seal to the required length.
- Attach magnetically or use adapter tape for non-magnetic surfaces.
- Check that the door fits evenly and test-run.
Maintenance & Care
- Check regularly for wear or cracks.
- Clean with mild cleaner.
- Replace after 5–10 years or when visible wear occurs.
- Check magnetic systems regularly for secure hold.
