Pradejón Decorative Concrete Breeze Block: light, air and design in a single block
The Pradejón decorative concrete breeze block is an open-work piece in white or grey concrete with a square, window-style opening. Stacked piece by piece, it forms an enclosure that filters views without shutting out light or air, with a relief that changes with the sun throughout the day. It is made in 2 thicknesses: the 17 cm format is a block for building open-work walls, and the 8 cm format is a breeze-block piece for lightweight enclosures and open-work cladding.
✅ Key advantages
Privacy with ventilation: blocks direct views while keeping air circulating.
Repeating pattern: the window motif creates a continuous grid when the pieces are laid together.
Concrete for outdoor use: precast concrete, unpainted and untreated, for permanent outdoor exposure.
Easy to calculate: 25 pieces per m² of visible face (20 × 20 cm).
Unit or pallet: buy only the pieces you need or the full pallet for the job site.
