Section 074216 - Insualted Core Metal Wall Panel s1

CENTRIA Formawall™ Graphix Series Insulated Core Metal Wall Panel System with Integrated Components

CENTRIA Formawall pressure-equalized insulated core metal wall panel system is designed as a complete wall solution. Formawall provides an air, water, vapor, and thermal barrier with total wall insulation values up to R21 in a single, easy-to-install finished system. Formawall eliminates the need for separate batt or board insulation, gypsum board sheathing, air barriers, vapor retarders, and building wraps, while providing better thermal efficiency and moisture control for exterior metal-clad walls.

Formawall systems include optional integrated window, translucent fiberglass sandwich panels, louver, and sunscreen components with compatible trims and finishes. The optional integrated through-tube system of structural supports can eliminate the need for separate metal stud supports while providing a finished interior solution.

Formawall was developed using ATMP® - CENTRIA's Advanced Thermal Moisture Protection building envelope science. This exciting product maximizes a metal wall system's ability to effectively control moisture without sacrificing thermal efficiency. Through extensive research and testing, the energy and cost savings of Formawall have made it a choice for architects across the country. Rainscreen design, streak-free dry seal joinery, exceptional panel flatness standards, and high-performance finishes - everything about Formawall and the CENTRIA network of experienced installers assures the architect of complete satisfaction in the finished project.

Panels are available in Kynar 500® or Hylar 5000®polyvinylidene fluoride (PVDF) finishes, including micas and metallics. Highly UV resistant and durable in the face chemical and air borne pollution, salt spray and wind-driven sand, PVDF coatings are the Gold Standard of the architectural exterior industry. CENTRIA Formawall wall systems are available in over 60 standard colors, and wide array of custom colors. CENTRIA Formawall panels are also available in stainless steel.

A companion guide specification is available from CENTRIA for projects that do not require CENTRIA's integrated window, wall, and sun screen units in a Formawall application.

CENTRIA 07 42 16 INSULATED CORE METAL WALL PANELS Page 24 of 25 Additional Specifier's' Notes for CENTRIA Formawall Metal Wall Panels

Substitution Reviews: When reviewing substitution requests for other products for compliance with this specification, CENTRIA recommends particular attention to the following issues:

Rainscreen system engineering: Require submittal of sample shop drawings from a similar project to determine whether the quality of the total proposed package meets CENTRIA's standards. Is the system a pressure-equalized system such as Formawall, or is it a barrier-type system that must rely on sheathing plus a weather barrier? Do edge conditions and opening conditions include extruded trim rather than formed metal, dry gasketing instead of liquid sealants, secondary framing meeting metal thickness and corrosion resistance requirements, and proper mounting hardware?

Quality of high performance finishes: Require submittal of large scale coating samples on the specified substrate to enable comparison of finish quality. Are desired colors and visual effects comparable to CENTRIA's own coating line finishes? Have previous projects with similar coating proven durable?

Examination of similar installations: Panel flatness and substrate flatness are important components of overall installation quality. Does the manufacturer/installer meet the CENTRIA's tolerances specified in this Section?

Coordination with Drawings: CENTRIA recommends you coordinate the following:

Show details of integrated window, wall louver, and sunscreen units. Show interfaces between panels, panel trim, and integrated units.

Show details that allow for moisture penetration into and weeping from the pressure-equalized cavity within the CENTRIA wall panel system. Show unobstructed path for moisture movement to the exterior, along with moisture barrier and flexible flashings specified in other Sections.

Detail edge conditions with extruded trims that protect the panel edges, especially at panel bottom.

Show extruded coping at top of wall condition provided under this Section for both detail and finish coordination.

Show soffits, sills, expansion joints and other components either specified in this Section or referenced from this Section to Related Sections.
