PBM Ventilation Blocks
PBM Ventilation Blocks are architectural concrete screen blocks designed to improve airflow, daylight penetration and façade expression. Often referred to as breeze blocks or decorative ventilation blocks, these units are widely used in tropical architecture for façade screens, boundary walls and feature partitions.
The PBM ventilation block system includes VentBlock, Veil Breeze Blocks (VBB) and Ventilation Block Plus (VB+), each engineered for different architectural applications ranging from large-scale façade systems to refined feature walls.

FAQ
What are ventilation blocks?
Ventilation blocks, also known as breeze blocks, are concrete screen blocks designed to allow air and filtered daylight to pass through a wall while maintaining privacy and architectural texture. They are commonly used for façades, boundary walls, car park ventilation screens and decorative feature walls.
Are PBM ventilation blocks structural?
PBM ventilation blocks are non-load-bearing concrete blocks. They are typically installed as screen walls, façade elements or decorative partitions within a structural frame system.
What is the difference between VentBlock, VBB and VB+?
PBM offers three ventilation block systems designed for different architectural applications.
VentBlock – a modular ventilation block series suitable for large-scale façade and infrastructure projects.
Veil Breeze Blocks (VBB) – architectural breeze blocks with sculptural profiles and a refined front surface.
Ventilation Block Plus (VB+) – premium screen blocks with identical finishes on both sides, ideal for feature walls and areas with dual-side visibility
Are ventilation blocks suitable for exterior walls?
Yes. Concrete ventilation blocks are suitable for exterior façade and screen wall applications. They are commonly used in tropical architecture to improve airflow, provide sun shading and create distinctive architectural patterns.
