LATICRETE Introduces Air Barrier C3 – A Versatile, Single-Coat Class III Air Barrier Designed to Complement the Industry Leading MVIS™ System

Installers can create a seamless membrane compatible with most wall assemblies, helping increase a building’s operational energy efficiency by up to 35%

LATICRETE, a leading manufacturer of globally proven construction solutions for the building industry, has rolled out Air Barrier C3 – a versatile Class III air barrier – and a first for LATICRETE. Compatible with numerous wall assemblies, including full brick and stone, adhered masonry veneer, siding panel systems, and more, Air Barrier C3 is easily applied via a roller or sprayer in a single coat that dries in less than two hours, reducing labor costs and leading to faster project completions. When paired with the LATICRETE® Masonry Veneer Installation System (MVIS™), architects and builders can now install the most comprehensive adhered veneer wall assembly system on the market, increasing a building’s operational energy efficiency by up to 35% and backed by a full system warranty.

“Building codes are constantly changing, creating new and unique scenarios for our customers,” said Spencer Maheu, LATICRETE Senior Director of Product Management. “Air Barrier C3 is the newest addition to our collection of state-of-the-art membranes, designed to give our customers the ability to adapt our MVIS system to any wall assembly, in any environment.”

Air Barrier C3 features Microban® antimicrobial product protection to help prevent bacteria growth that may lead to stains and odors, reducing ongoing maintenance and keeping installations looking newer longer. The Class III air barrier has also achieved some of the industry’s highest standards. UL Greenguard has certified the product for low VOC emissions to help create a healthier work environment for installers and contribute to a project’s sustainability goals, and the Air Barrier Association of America’s (ABAA) certification means it will meet the rigors encountered during its service life.

“Air Barrier C3 provides architects and specifiers a solution that checks all the boxes – versatility, compatibility and peace of mind,” added Maheu.
