In an era of increasing awareness about air quality, ventilation grilles have become crucial for a healthy environment. The choice you make has an effect on the removal of pollutants and the regulation of humidity. How do you choose ventilation grilles for your property to support the functioning of the building while ensuring constant air circulation?

The Importance of Ventilation Grilles for Air Quality and Comfort

Ventilation grilles play a significant role in ensuring comfort and health indoors. Proper installation is the foundation of effective ventilation. Grilles eliminate pollutants and regulate humidity. Moreover, they prevent the growth of harmful microorganisms like mould and fungi. In this article, we will discuss how to choose the ideal ventilation grilles for various types of buildings to ensure optimal air quality, support the building’s functionality, and maintain constant air circulation.

Choosing Ventilation Grilles – What to Consider?

First and foremost, the purpose of the ventilation grille is crucial for its effective functioning. The installation location significantly influences the choice of the appropriate product. Starting with the installation location (on the wall, ceiling, floor, or in the spiro system) narrows down the search scope. Identifying environmental conditions and the degree of aggressiveness of external factors is the next step, allowing for the selection of corrosion-resistant materials, which directly affects the durability of the ventilation grille. Choosing the right coating can provide protection ranging from C2 to C5.

Optimising Ventilation Grille Selection: Size and Quantity in the
Context of Room Geometry

The size and quantity of ventilation grilles should be tailored, considering room geometry and airflow requirements. Depending on the required airflow, you should choose one larger grille or several smaller ones, considering spatial constraints and aesthetics. Accurate selection requires knowledge of air velocity in the duct, the required airflow, and the effective flow area of the ventilation grille.

Which Materials to Avoid When Choosing Ventilation Grilles?

The best material for producing ventilation grilles is not straightforward, as the choice depends on various factors. Our range predominantly includes materials like galvanised steel (SO), stainless steel (SN), painted steel (SL), painted aluminium (AL), and anodised aluminium (AA). The choice of material should primarily be dictated by the grille’s purpose, its weight requirements, strength, corrosion resistance, and aesthetics.

Optimal Material Choices for Ventilation Grilles in the Context of Aesthetics and Functional Requirements in Office Spaces

For example, in office spaces where visual aspects and meeting specific design requirements regarding colour are important, painted steel or painted aluminium are preferred materials. In such environments, there is usually no need for high corrosion resistance materials since the environment is not aggressive.

There is no universally best material for all ventilation grille applications. It is crucial to choose the material that best suits the specific application, considering the installation location and the functional and aesthetic requirements.

What Are SMAY Ventilation Grilles Made Of?

At SMAY, we place great emphasis on the individual needs of each project, offering a wide range of grille sizes, ranging from the smallest dimensions of 75×75 mm to the largest standard one-piece dimensions of 1225×625 mm or linear dimensions of 2000×350 mm. By combining grilles into batteries, even larger dimensions can be achieved, showcasing the company’s flexibility in adapting to specific project requirements. Additionally, a rich range of accessories, such as adjustable dampers, mesh screens, plenum boxes, caps, or mounting frames, allows for creating personalised ventilation solutions.

Custom Solutions? It’s Standard at SMAY

SMAY is open to seeking non-standard solutions, including in the area of finishes and corrosion classes. If the standard finish offers a C3 corrosion class, but the project requires a higher class, it is possible to use other materials or protections, such as specialised painting, to fully meet the needs of the specific application.

Ventilation Grille Installation and Proper Sizing

Ventilation grilles are typically ordered and confirmed by the dimensions of the mounting hole and marked as C, D.

C x D -> Mounting hole dimension C – horizontal dimension D – vertical dimension

E x F -> Grille opening dimension E – horizontal dimension F – vertical dimension

A x B -> External dimension A – horizontal dimension B – vertical dimension

Grilles can be mounted with visible screws from the front or with a hidden snap-in. For larger grille dimensions, a securing screw (type R mounting) is recommended for snap-in installation. Depending on where the ventilation grille is to be installed, a mounting frame or plenum box can be selected. If the grille is to be placed on the side of a spiro pipe, a dedicated grille for spiro or a standard grille with an NDS cap can be ordered.

Wide Range of SMAY Ventilation Grilles

Ventilation grilles from the AL and ST lines are gaining the most popularity due to their versatility, including a wide range of available sizes, various finishing options, a rich assortment of accessories, and the choice between single- and double-row models.

A particularly notable model is the ALG, which is gaining recognition for its ability to create impressive linear connections. This rectangular aluminium grille features a first row of fixed blades, with the option to add a second row of adjustable blades, further enhancing its functionality.

Also noteworthy is the ALF grille, dedicated to floor applications and made of anodised aluminium. The characteristic 15⁰ blade angle allows precise airflow direction, while additional accessories, such as dampers, offer the ability to regulate airflow, significantly impacting user comfort and the efficiency of the ventilation system.

Effective Ventilation Through Appropriate Grilles

Ventilation grilles are an integral part of an effective ventilation system and play a key role in ensuring indoor air quality. Their appropriate selection, considering both functional and aesthetic requirements, is fundamental for maintaining a healthy and comfortable environment for users.

Key Aspects of Ventilation Grille Selection

Proper installation and material selection, tailored to the specifics of the
location and environmental conditions, allow for efficient removal of pollutants, humidity regulation, and prevention of unwanted microorganism growth. Therefore, when planning a ventilation system, a comprehensive approach to selecting ventilation grilles is essential to maximise their functionality while maintaining the installation’s aesthetics and durability.
