Weather Protection Grilles

Ohnsorg’s weather protection grilles stand as a testament to the perfect blend of functionality and aesthetics. Crafted meticulously, these grilles are designed to withstand the test of time, ensuring that your building facades and roof outlets remain protected against the harshest of weather conditions.

Constructed with weather-resistant slats, these grilles are not just about durability. They come with an added layer of protection in the form of a stainless steel protective grille on the inside. This ensures that while the exterior combats the weather, the interior remains free from debris, insects, and other unwanted elements.

One of the standout features of Ohnsorg’s weather protection grilles is their stylish design. Whether installed on building facades or integrated into roof outlets and ventilation hoods, they invariably become a focal point, drawing attention and admiration. Their sleek design complements both modern and traditional architectural styles, making them a versatile choice for a range of buildings.

The mesh grille, made of Cr.Ni.Steel with a 10/10 mm dimension, ensures optimal airflow with a free cross section of 65%. With an installation depth of 48 mm, these grilles are designed to fit seamlessly into various structures. The minimum size specifications stand at a length of 90 mm and a width of 90 mm, ensuring they are suitable for a wide range of applications.

For those who are particularly concerned about smaller pests, there’s an option to upgrade. Instead of the standard mesh grille, customers can opt for a fly screen at an additional charge. This ensures even finer protection, keeping out even the tiniest of insects while maintaining airflow.

In conclusion, Ohnsorg’s weather protection grilles are more than just a protective measure. They are a statement of style, a commitment to quality, and a promise of durability. Whether you’re an architect, a builder, or a homeowner, these grilles promise to be a valuable addition to your property.
