HOW TO PREVENT WIND RATTLE WITH ALUMINIUM COPINGS?

How To Prevent Wind Rattle With Aluminium Copings?

Using aluminium to protect a perimeter wall from rain, temperature, and the elements is a great way to ensure the longevity of the structure. 

Aluminium copings are a great addition to the top side of deck railing. This type of finishing protects the rail from weather, spilt drinks, and makes it more comfortable for the end user.

However, due to their lightweight and proportions, aluminium copings do have a tendency to get the wind caught beneath them and to make an unpleasant rattling noise. This rattling can be persistent. It can be annoying, and in the worst cases, a strong wind can dislodge them.

Here, we will discuss proven ways to prevent these bespoke aluminium fabrications from succumbing to the effects of persistent and strong wind.

How To Prevent Wind Rattle With Aluminium Copings

#1 Use professional aluminium fabricators
#2 Consider your spacings
#3 Welding instead of fasteners
#4 Pass through pickets
#5 Whistling
#6 Rubber strips and adhesives

1. Use Professional Aluminium Fabricators

Your first priority should be to work with professional-grade aluminium fabricators. They will be able to perform engineering calculations that are specific to the needs of the installation.

2. Consider Your Spacings

Because vibration can occur on installations that contain longer structural components, be sure that your post spacings are 48” on the centre or better, to avoid wind rattle.

3. Welding Instead of Fasteners

Consider asking your aluminium fabricator to use welding as a means of securing your aluminium copings in place, rather than using mechanical fasteners.

Mechanical fasteners will always offer at least a slight amount of play. When under pressure from wind, that play will result in wear and tear that will increase the rattling problem. This can even lead to the failure of aluminium copings to remain in place.

4. Pass Through Pickets

Think twice about using pass through pickets. These types of systems come with some inherent weaknesses. Even if your railing pickets are welded onto the top and bottom rails, vibrations and rattling can still occur if they are not welded or otherwise firmly affixed to the pass-through component.

5. Whistling

Another common complaint with aluminium copings that can be avoided is whistling. When wind moves past or through the gaps between the edged of the copings and the rail, it generates a shrill and persistent noise.

On one hand, this can be aggravating, but on the other, it is warning you that a potential mechanical problem may arise – especially if your copings are not fastened in place solidly.

6.Rubber Strips and Adhesives

Rubber strips and adhesives are a good alternative to either mechanical methods of fastening copings to rails or even welding.

Mechanical fastening is easy to disassemble, and welding is strong. But the same effect can be achieved using weatherproof rubber strips and adhesive. These can be made and applied in such a way that any existing gap between the rail and the aluminium coping is filled in.

This prevents water and pests from getting inside and causing rot and other unpleasant effects. But if properly applied, it can also present a wind profile that will not be conducive to whistling or even rattling. Rubber strips and adhesive may need to be replaced periodically.
