CLADDING Overview System Requirements * Continuous vertical support structure behind cladding * Minimum general cavity depth (dimension from the sheathing or the face of exterior insulation to rear of cladding) - 1" (26mm) * Minimum localized cavity depth (dimension from the sheathing or the face of exterior insulation to rear of cladding) - 1/2" (13mm) * Minimum ventilation at top and bottom of rainscreen cladding system (2.4in2/lft minimum) * Appropriate weather resistive barrier* * Emphasis on flashing and redirection of water * Appropriate dead and live load structural design Continuous Weather Resistive Barriers Drained & back ventilated systems (D&BV) typically require a continuous weather resistive barrier at the rear of the cavity, usually located on the outer face of the inner leaf. Typical characteristics are: * UV stable * Self-sealing or self-cinching * Black in color The UV stability requirement is due to the open joint design of the D&BV system and the potential long-term exposure of the weather barrier to ultraviolet rays from the sun. The black in color requirement is to minimize the visual impact of the weather barrier and increase the aesthetic sensibility. If necessary, both of these requirements can be achieved through the installation of a black flashing membrane over the existing weather barrier. The weather barrier should be installed and all penetrations and seams should be sealed per the manufacturer's written instruction. - 34 - www.monarchmetal.com (631)750-3000http://www.monarchmetal.com http://www.monarchmetal.com
