Frequently asked questions about exterior blinds: What you really need to know

External blinds are a popular sun protection and create a pleasant indoor climate – yet many people have very practical questions about them. From choosing the right blinds to maintenance and purchasing replacement parts: In this blog post, we answer common questions that interested parties ask repeatedly. This provides you with important information and helps you make informed decisions, whether you want to buy new external blinds or repair existing ones.

1. What are external blinds and how do they differ from roller shutters?

  • Function : Exterior blinds typically consist of slats that can be adjusted in angle. This allows you to determine how much light you want to keep in or out.
  • Roller shutters, on the other hand, completely close off the window area (and are often better suited for burglary protection).
  • Advantage of external blinds : The flexible adjustment allows you to block out dazzling light while letting fresh air into the room.

2. What types of external blinds are there?

1. Manual external blinds

    • Operated by hand crank.
    • Advantage : Cheaper to purchase, no power connection required.
    • Disadvantage : Less comfortable to use, cranking can be strenuous on larger systems.

2. Electric external blinds

    • Have a motor and are controlled by switch, remote control or app.
    • Advantage : Convenient, often integrated into smart home systems.
    • Disadvantage : Higher purchase price and possible installation costs due to electrical connection.

3. Semi-automatic solutions

    • Combine manual technology with simplified operation (e.g. crank with spring mechanism).
    • Advantage : Practical for smaller windows when an electric motor is not worthwhile.

3. How do I properly care for and clean external blinds?

  • Regular wiping : Leaves, dust, and pollen accumulate on the slats. A soft cloth or slat brush prevents long-term soiling.
  • Do not use aggressive cleaners : Chemicals or rough sponges can scratch the surface or damage the paint.
  • Be careful with high-pressure cleaners : The powerful water jet can bend the fins or force water into the engine/gearbox. It's better to clean with a hose or bucket.

4. What are the most common problems and how do I fix them?

1. Broken cords or tex bands

2. Bent slats

    • Problem: One or more slats may be bent due to storms or accidental damage.
    • Solution: Sometimes the slat can be carefully bent back. Severely damaged slats require replacement.

3. Defective reversing gear

4. Motor malfunctions in electric blinds

5. What spare parts are available in shops?

  • Slats : Available in different colors , widths and materials (aluminum, plastic).
  • Tex tapes & cords : These are used to raise and lower the external blinds, often UV-resistant and available in different thicknesses.
  • Gearbox & tilting rods : Important for tilting the slats.
  • Guide nipples & side rails : Keep the blinds stable in the track.
  • Here you will find guide nipples from all manufacturers
  • Motor & control technology : For all those who want to convert from manual to electric operation or need to replace an old motor.

6. Can you install external blinds yourself?

  • Possible DIY solution : With precise instructions and a little craftsmanship, you can install a manual external blind yourself.
  • Electrical versions : An electrical connection is often necessary here – you may need to consult a specialist.
  • Manufacturer recommendations : Many brands like Warema and Hella provide detailed installation instructions. These will show you step-by-step how to proceed.

When is professional help worthwhile?

  • With large systems or windows located at higher levels (upper floors), installation can quickly become dangerous. A professional has the necessary expertise and equipment to prevent damage or accidents.

7. How do I choose the right exterior blinds?

1. Window size & installation situation

    • Are you a tenant and are you allowed to make structural changes?
    • Should the blinds be attached to the facade or the window frame?

2. Material & Color

    • Aluminum is robust and durable.
    • There are countless colors that can be based on the house facade.

3. Operation

    • Manual, electric or smart home system?
    • Plan your budget accordingly.

4. Budget

    • Manual blinds are cheaper, while electric versions offer more comfort but are more expensive to purchase.

8. Is it worth upgrading to electric exterior blinds?

  • Time saving : You don't have to crank every window, but control it by pressing a button or even using an app.
  • Automatic control : With time and light sensors, the blinds move up or down automatically.
  • Cost factor : More expensive to purchase, possibly additional costs for power cables and installation.

Conclusion

If you value comfort and state-of-the-art technology, electric exterior blinds can be a worthwhile investment. Those who prefer a more classic and affordable option will also benefit from manual models .

9. Tips for saving energy and indoor climate

  • Heat protection : External blinds block the sun's rays before they reach the window pane – this can noticeably lower the indoor temperature.
