Westcoat ALX and ALX Pro Receive Class A, One-Hour and Class I ICC Listings

– Westcoat Specialty Coating Systems is proud to announce that the ALX Pro System, in both Standard and Custom finishes, has been independently tested to meet the Acceptance Criteria for Walking Decks (AC39) and has received certification through ICC. It joins ALX Standard and Custom on the updated ICC-ES Evaluation Report ESR-2201.

Long known for its Class A and One-Hour Fire Ratings, Westcoat’s ALX received the ICC-ES Class I Vapor Retarder (0.1 perm or less) listing in June 2017 with ALX Pro receiving its listing in September 2017.  This certification comes at a crucial time when building code standards for waterproofing decks are becoming more stringent. Some cities and counties in California are already enforcing the need for this E96 testing certification prior to any statewide change.

All Westcoat ALX and ALX Pro systems provide a Class A Roof Covering Classification (ASTM E108) and One-Hour Fire Rating (ASTM E119). In addition to these certifications, when WP-40 Sheet Membrane is applied over the entire plywood substrate, both ALX and ALX Pro in Standard and Custom finishes meet classification for a Class I Vapor Retarder (ASTM E96). The full listings can be found on the ALX page of 
What is ALX Pro? 
The ALX Pro system features all the proven attributes and benefits of the existing ALX system, but features an additional Fiberlath Resin Membrane layer. This additional layer provides greater waterproofing and helps protect against cracking, especially on larger spans or cantilever decks.
ALX is the clear choice when choosing a waterproofing system for elevated decks and walkways. It is the ultimate protection for the end user, applicator and specifier. When installed by a Westcoat QCA, these systems are eligible for up to a 15-year warranty. Contact Westcoat for a referral to a QCA or more information on the ALX systems.
