Living in a region exposed to gusts, such as the Rhône Valley or the seaside, imposes specific constraints for outdoor landscaping. The fear of seeing your fence torn down or deformed after a storm is legitimate. While aluminum is praised for its modern aesthetic and durability, is it truly capable of withstanding the force of Aeolus (wind)? Rest assured: with the right model and an adapted installation technique, aluminum is a perfectly reliable solution.
The Importance of Wind Resistance
The main enemy of your installation is not the material itself, but its wind resistance. A solid fence acts exactly like a boat sail: it completely blocks the airflow, which exerts colossal mechanical pressure on the panels and, by extension, on the posts. In strong winds, this pressure can bend the metal or tear out the fixings.
To limit this risk, the most effective solution is to reduce air resistance. An openwork or semi-openwork aluminum fence allows wind to pass through the structure rather than hitting it head-on. This drastically reduces the stress exerted on the structure, ensuring its longevity without sacrificing the aesthetics of your garden.
Louvered Slats: The Ideal Compromise
If you wish to maintain your privacy while securing your fence against gusts, models with louvered slats are essential. Thanks to their specific inclination, these slats break direct sight (an occulting effect) while allowing air to circulate between the gaps.
This type of profile “breaks” the force of the wind and prevents the effect of an insurmountable wall. At an expert like Districlos, these models are designed to offer the best ratio between privacy and aerodynamics, thus protecting your property from prying eyes without compromising the solidity of the structure.
Embedding or Base Plate: Installation Makes the Difference
Even the most robust fence on the market will not hold if its anchoring is faulty. In windy areas, installation on base plates (screwed onto a low wall) is often not recommended for significant heights or solid panels, as the leverage effect risks tearing out the anchor bolts.
The safest method remains embedding the posts in concrete. A deep anchorage (generally 50 cm into the ground or low wall) allows the wind load to be transferred directly into the foundations. It is this solidarity between the aluminum post and the masonry that guarantees the mechanical resistance of the entire structure against extreme weather.
Aluminum’s Rigidity Compared to Other Materials
Contrary to popular belief, aluminum is an excellent choice for windy conditions, often superior to low-end PVC or composite. Where PVC can become brittle under the effect of cold and vibrations, aluminum retains a certain flexibility while being extremely rigid thanks to its extruded profiles.
Furthermore, aluminum does not rust. By the sea, where the wind often carries corrosive salt spray, a wrought iron fence would eventually deteriorate. Powder-coated aluminum perfectly resists this aggressive environment, ensuring that the fixing points will not be weakened by corrosion over the years.
Golden Rules for a Durable Installation
To sleep soundly during the next storm, it is advisable to comply with certain installation standards. In addition to choosing embedding, you can strengthen the structure by reducing the spacing between posts. Bringing the anchor points closer together stiffens the fence line and better distributes wind pressure.
Here are the essential criteria to check for your project in an exposed area:
- Opt for an openwork or louvered model to reduce windage.
- It is imperative to choose posts to be embedded rather than those on base plates.
- Check the thickness of the aluminum for the posts and slats.
- Adapt the height of the fence to the exposure of your property.
