Masonry Block 20 Series

Adaptable for Any Application

From standalone walls to entire structures, the 20 Series provides flexibility without sacrificing strength. Its well-balanced size and composition make it suitable for a variety of construction styles and layouts.

Engineered for Occupant Wellbeing

These masonry blocks don’t just hold up a building, they enhance how it feels inside. With strong acoustic insulation properties and improved thermal performance, they help reduce noise and regulate internal temperatures, creating a more peaceful and energy-efficient space.

Reliable, Resilient, and Ready to Perform

The 20 Series stands up to the demands of the building environment while offering the design freedom builders need. Whether finished in a refined surface or left natural, you can count on Bowers quality to stand the test of time.
