Often enduring more than a hundred years, brick masonry is testimony to the traditional collaboration between architect, engineer, and mason. Beauty and historical significance are often the most compelling features of brickwork.
Masonry is a 5000-year-old building technology proven to perform well in all types of built environments, given its inherent resistance to fire, insects, and moisture degradation. However, the expectations for buildings have grown from simply providing shelter to maximizing use of renewable, recycled, and recyclable materials, as well as space, energy, sound, and light.
The walls of today’s masonry buildings are becoming more complex than ever, with designs modified to meet new energy code requirements. This evolution means more components in walls than ever before, and they can all come from different manufacturers. One of a designer’s biggest challenges is deciding which materials will both meet the building’s needs and be compatible with one another.
