Paintable Vent Grille

Paintable vent grille solutions for seamless interiors

A paintable vent grille is the preferred specification when architects and interior designers want ventilation that visually disappears into the architecture. Ventmann’s plaster-in diffusers and grilles are engineered to be skimmed, primed and painted the same colour as the surrounding wall or ceiling, delivering a continuous, high-end finish without visible plastic covers or metal frames.

Unlike surface-mounted vents, a paintable vent grille integrates directly into plasterboard or solid ceilings. After installation, the unit is skim-coated, sealed with PVA primer and painted with the same finish as the surrounding surface. The result is a clean, monolithic appearance with professional airflow performance.

Why choose a paintable vent grille?

Modern interiors prioritise minimalism and uninterrupted surfaces. Traditional plastic grilles break sightlines and rarely match wall colours. A paintable vent grille resolves this by becoming part of the architecture rather than an add-on.

Key advantages:

• Fully paintable after skim coat and primer
• Flush integration into plasterboard or ceiling
• No visible frames or plastic elements
• Suitable for walls and ceilings
• Ideal for residential and commercial interiors
• Long-term durability without discolouration

Ventmann grilles are manufactured from advanced gypsum-based composite materials designed for plaster integration. Once installed and finished, they can be painted with standard wall or ceiling paint to achieve a uniform aesthetic.

How Ventmann paintable vent grilles are finished

All Ventmann plaster-in grilles and diffusers are designed to be finished on site using standard drywall processes. The finishing sequence is straightforward and familiar to contractors:

• Install the grille within plasterboard or ceiling system
• Apply jointing compound or skim coat
• Sand and level the surface
• Apply PVA primer/sealer
• Paint with chosen wall or ceiling paint

Once completed, the paintable vent grille blends seamlessly with the surrounding surface. Only the airflow slot or perforation pattern remains visible, maintaining ventilation performance without visual disruption.

Designed for architects and interior designers

A paintable vent grille is often specified in projects where visual consistency is critical. Ventmann products are used in:

• High-end residential properties
• Hotels and hospitality spaces
• Retail environments
• Offices and commercial interiors
• Renovation and refurbishment projects

Because the grille can be painted the same colour as surrounding finishes, it supports minimalist design strategies and eliminates visual clutter from ceilings and walls.

Installation compatibility

Ventmann paintable vent grille systems are compatible with:

• 12.5 mm plasterboard
• Gypsum ceilings
• Suspended ceilings
• Solid wall construction
• New build and retrofit applications

Each grille is engineered for secure installation and long-term stability within plastered surfaces.

Sustainable alternative to plastic vents

Traditional plastic vent covers often discolour, crack or become visually dated. A paintable vent grille offers a longer-lasting and more sustainable alternative:

• Durable gypsum composite construction
• Reduced reliance on plastic components
• Long lifecycle within the building
• Can be repainted during redecorations

This makes them particularly suitable for projects focused on longevity and material quality.

Achieve an invisible ventilation finish

When ventilation needs to perform without drawing attention, a paintable vent grille is the optimal solution. By integrating directly into the plaster surface and finishing with standard paint, Ventmann grilles provide both architectural discretion and engineered airflow.

For designers and contractors seeking a refined alternative to visible air vents, Ventmann’s paintable plaster-in diffusers deliver a seamless result that aligns with contemporary interior standards.
