About Acousta-Wal

Acousta-Wal® sound-absorbing masonry units are your acoustical and aesthetic solution in one product. Whether it’s a school gym, lecture hall or performance arts center, acoustical CMUs are your indoor/outdoor solution to sound absorption and control. Its unique design controls sound transmission as it absorbs sound waves. The Acousta-Wal system works to absorb sound at all frequencies, even the difficult-to-control low frequencies.

Acousta-Wal is a performance upgrade option, which may be added to a number of structural concrete masonry units. It has a closed top and vertical slots on its face, exposing the inner cavity. Working much like an automobile muffler, the closed-end cavities of the different size units resonate to sound waves of different frequencies, converting them harmlessly to heat.

Green Building Design with Concrete Masonry Units (LU/HSW)

CEU Credits: 1 LU | HSW

Green building strategies – in accordance with or independent of LEED standards – continue to rise in importance across all building types.
 
This course will discuss the green building and sustainable design benefits of concrete masonry including life cycle costs, durability, energy performance, and safety. Additionally, the course will detail how building with concrete masonry can contribute to specific LEED credits, and to the health, safety, and indoor comfort of the occupant.
 
After completing this course, attendees will be able to: 
• Become familiar with the ways in which concrete masonry can potentially contribute to economical and sustainable building practices. 
• Identify concrete masonry's inherent sustainable qualities. 
• Identify changes to LEED in relation to specifying concrete masonry.
• Explain how concrete masonry can prevent the growth of mold in the building.
 
This course is applicable to all masonry products.

Masonry and Leed v4.1 (LU/HSW)

Lunch and Learn
Masonry and Leed v4.1 (LU/HSW)

CEU Credits: 1 LU 

Sustainable design and green building are ever-evolving, with the latest version, LEED v4.1 introduced in 2019. 

This course will explore the latest modifications to the LEED standard, with a particular emphasis on masonry compliance and contribution. Developed by LEED expert Christine A. Subasic, P.E., LEED A.P., the course will introduce attendees to sustainable design and provide an overview of the LEED Rating System, and its credit categories, with a particular emphasis on Materials and Resources, as well as covering criteria and considerations used in selecting masonry products for LEED projects.

After completing this course, attendees will be able to: 
• Understand the changes in the Materials and Resources credit category in LEED v4. 
• Identify elements of sustainable design that are not always part of green building rating systems. 
• Provide an overview of the LEED v4.1 BD+C New Construction Rating System. 
• Explain sustainable design strategies and LEED strategies that utilize masonry.
 
This course is applicable to all masonry products.

Designing with Masonry for a Healthier, Safer Building Environment (LU/HSW)
CEU Credits: 1 LU | HSW

Masonry delivers a variety of benefits to occupants and designers alike including being highly environmentally-friendly due to its durability and reduced embodied energy compared to other structural building materials. 

This course will discuss ASTM specification classifications, as well as the various texture, pattern and color variations offered by masonry. Additionally, the course will review the environmental contributions that masonry offers the architect including the prevention of moisture and mold in construction projects and protentional LEED credits.

After completing this course, attendees will be able to: 
• Identify the performance characteristics of the various types of architectural masonry. 
• Understand different ASTM Classifications and how these affect the architect's specification of concrete masonry. 
• Discuss the proper detailing of concrete masonry to prevent moisture intrusion. 
• Explain the LEED rating system and how masonry plays a part in achieving LEED certification.
 
This course is applicable to all masonry product lines.

Acoustics vary with such dynamics as room size, flooring type, window treatments and seating materials. The approach to this analysis depends on if you're trying to dampen sound within the room or trying to block sound from an adjacent area.
