Allt du behöver veta om att välja rätt snörematerial, tjocklek och typ för dina persienner
One thing is certain when it comes to blinds cord - one day it will wear out. Preferably, of course, you want the wear to be slow and the blind cord to last as long as possible.
So let's see what the options are and what is the best choice when you are looking for a new cord for your blinds. We'll look at material, cord thickness and color options.
Material Comparison: Nylon, Polypropylene & Polyester
Polyester
Our top choice for Venetian blind cord due to its exceptional durability and UV resistance.
Nylon
Very strong material, but has significant drawbacks for blind applications.
Polypropylene (PP)
Budget-friendly option, but compromises on quality and longevity.
Why UV Resistance Matters
Blinds hang exactly where there is the most light exposure. UV resistance is crucial for longevity. While polypropylene may seem cheaper initially, you'll spend more over time due to frequent replacements and the hassle of re-stringing your blinds.
Electric Blinds and Blind Cord
If you have electric blinds, you still need cord for rolling them in and out. When rolling in, the motor turns so that the blind cord is twisted on a bushing, thus rolling the blind in.
In an electric blind, there are two louver cords:
- One that tilts the slats. It lies loose over the bush, allowing it to tilt the slats without rotating further.
- The cord that pulls the slats up is attached to the roll-up box with a knot and is rolled in and out.
Electric Blind Advantage
With electric blinds, cord replacement is generally needed less often. The constant force and controlled run-in speed create less friction, which means less wear and tear on the cord.
Because the motor works this way, you also never see electric blinds with ladder tape. The cord that pulls the slats up is the one you'll usually need to replace.
Choosing the Right Cord Thickness
The larger the blind, the thicker the cord should be. To determine which cord you need, you can look at the blind body size.
Quick Reference
For blind bodies measuring 25 mm to 35 mm, a cord of 1.0 to 1.3 mm diameter will be sufficient. For wooden blinds with a tray of 50 mm or larger, choose a 2.5 mm diameter cord.
Cord Selection Guide by Blind Type
| Blind Type | Recommended Diameter |
|---|---|
| Aluminum Blinds | 1.1 to 1.7 mm |
| Wooden Blinds | 2.5 mm |
| Flyscreen / Mosquito Net Systems | 1.1 mm |
Construction of Venetian Blind Cord
Venetian blind cord is made of braided polyester with a core from 1.7 mm diameter. Below that diameter, it is hollow braided because the diameter is so small.
Polyester is one of the most hard-wearing and UV-resistant types of rope. It's available in white and black for standard applications.
0.8 mm diameter polyester is also often used as louver cord, even though it is not specifically made for that purpose. This cord is available in many colors and comes on reels of 90 meters.
