Ventilation Block Plus (VB+)
Ventilation Block Plus (VB+) is a premium concrete screen block system engineered with a refined finish on both faces.
Unlike conventional ventilation blocks, VB+ provides identical surface quality front and back, making it suitable for feature walls and façade applications where dual-side visibility is required.
Designed for commercial and residential projects, VB+ enhances ventilation, daylight penetration and architectural depth while maintaining a clean, modern expression.

FAQ
What makes VB+ different from other ventilation blocks?
VB+ features a refined finish on both faces, providing identical surface quality front and back. This makes it suitable for applications where both sides of the wall are visible.
When should VB+ be specified instead of VBB?
VB+ is recommended for projects requiring dual-visibility screen walls, while VBB is typically used where only the front-facing surface is visually exposed.
What depth options are available for VB+?
VB+ is available in 100mm depth, with selected models offering a 65mm option for slimmer wall profiles.
Are PBM ventilation blocks suitable for outdoor use?
VentBlock, VBB and VB+ are manufactured from concrete and are suitable for indoor and outdoor architectural applications, subject to proper installation practices.
Are ventilation blocks load-bearing?
Ventilation blocks are typically used as non-load-bearing screen or façade elements. Structural requirements should be confirmed with project consultants.
