Acoustic Glass Performance Fundamentals
An Introduction to Glass Specifications and Acoustic Performance Metrics
About This CPD
Join us for an introductory technical CPD on acoustic glass performance. This session provides the foundation for understanding glass specifications and how they relate to sound insulation in building envelopes.
Presented by Eugene Korch (IAST) and Marc Fuzellier (Atelier Crescendo), this webinar demystifies the terminology and metrics used in acoustic glass specifications, helping design professionals understand the fundamentals before engaging with specialist consultants or manufacturers.
This introductory session covers:
Reading glazing unit formulas – understanding glass types, thicknesses, spacers, gas fills, and laminated construction
Sound fundamentals – frequency ranges, sound intensity, and real-world noise sources
Acoustic metrics – Rw values, spectrum adaptation terms (C and Ctr), and their applications
Design parameters – mass, asymmetry, cavity tuning, and laminated interlayers
Common misconceptions – clarifying which parameters affect acoustic performance and which don't
Using simplified diagrams and conceptual explanations, this CPD focuses on building foundational knowledge. This is an introductory session – it provides the vocabulary and framework you'll need when working with acoustic consultants and reviewing manufacturer specifications.
What You'll Learn
Interpret glazing unit specifications and understand each component's role
Differentiate between annealed, toughened, and heat-strengthened glass
Understand different interlayer types and their roles in acoustic performance
Recognize how spacer types, cavity widths, and gas fills relate to performance
Identify sound frequencies and their real-world sources
Understand Rw, C, and Ctr values and when each is relevant
Recognize which glass parameters impact acoustic performance, and which common assumptions are incorrect
Who Should Attend
Architects, Architectural Technologists, Envelope Designers, Façade Specialist Contractors, Junior Façade Engineers, Building Envelope Consultants, Structural Engineers, Developers, Project Managers, Building Control Officers, Regulators, and Cost Consultants.
This session is designed for design professionals who need foundational knowledge of acoustic glass terminology and metrics, particularly those who work with acoustic consultants or review glass specifications but may not have specialist acoustic engineering backgrounds.
