Purposeful and Decorative Ventilation Grille Design

Ventilation is of primary concern to architects. When designed well, it can make a building come alive and can help building owners achieve green energy savings through improved ventilation. Every building design is unique. Therefore the Net Free Area requirements for ventilation grilles can vary vastly.

Here at Jonite, with over 20 years of experience in the materials industry partnering with landscape architects, we understand this deeply. All of our decorative ventilation grilles can be customized to fit your requirements for open area percentage of ventilation, span, or design.

A Better Alternative to Standard Grilles

Traditional metal ventilation grilles are typically highly functional but non-decorative. We design our ventilation grilles with the aspiration of bringing an exciting alternative to aluminum or metallic alloy ventilation grilles through the introduction of beautiful reinforced stone products.

At Jonite, we took inspiration from the aesthetically appealing stone of castles built during the Middle Ages to create visually pleasing pieces such as drains, grates and grilles. We offer ways to personalize your order’s appearance with various sizes, colors and shapes, including earthy motifs and avant-garde patterns. The customized stone comes with a natural, luxurious finish.

Benefits of Our Modern Ventilation Grilles

Architects can expand their hardscape and urban designs to anywhere their imagination bring them. Ventilation grilles no longer need to be hidden, concealed, or minimized- but can become an entire design highlight or blended into the other hardscape design elements. Some advantages of our custom grilles include the following:

  • Excellent load-bearing strength: The durable materials consist of advanced hybrid polymers and 95% aggregates. Reinforcement with specially treated steel frames gives these grilles reliable performance and ensures they meet international standards for bearing loads.
  • Creative and unique designs: Leveraging on Jonite ventilation grilles’  excellent load-bearing strength, architects can now incorporate ventilation in other applications that were not possible in the past. This custom feature opens up an exciting avenue to express creativity and create something unique — the possibilities are endless and if you can specify it, we can custom-build it.
  • Versatile uses in commercial settings: Architects have used the power of our grates to circumvent safety issues of ventilation being situated directly above the basement carpark. Other architects have used Jonite custom ventilation grilles for multiple purposes as both ventilation and a walking platform.

Can I design a ventilation grille to a specific open area?

Yes, we can make a custom ventilation grille based on your required open area. We will also take your preferred design, size, or any other parameter into consideration as well.

Can Jonite ventilation grilles be used for both vertical and horizontal installation?

Yes. Our ventilation grilles have a high compressive load strength for sturdy horizontal installation intended for minimal pedestrian use. For vertical installation, load-bearing requirements are usually not needed, but Jonite ventilation grilles are rated for at least 5KN.

Do you provide the fixtures for vertical ventilation installation?

Unfortunately, no. Jonite only designs and manufactures the panels required for your vertical installations without any fixtures and fittings.

Can Jonite ventilation grilles be customized for vehicular application?

Yes, but designs may be limited. Just like Jonite trench grates, customization may also depend on the size and Load Class required. Please feel free to contact us to explore which options suit you best.

What is the largest size of panel I can customize?

Our largest custom panel size is 1-meter x 1-meter.
