Standard Practice for Installation of Rigid Poly(Vinyl Chloride) (PVC) Siding and Soffit
ABSTRACT
This practice covers the minimum requirements for and the methods of installation of rigid vinyl siding, soffits, and accessories on the exterior wall and soffit areas of buildings. This practice also covers aspects of installation relating to effectiveness and durability in service. Materials to be used in the installation shall include horizontal wall sliding, vertical wall sliding, soffit panels, accessories such as starter strip, corner posts, and trim channels, and fasteners such as nails, staples, and screws. The installation method includes the following steps: substrate, surface preparation, application of horizontal sliding, application of vertical sliding, application of soffits and fascia and applicaton of special details.
SCOPE
1.1 This practice covers the minimum requirements for and the methods of installation of rigid vinyl siding, soffits, and accessories on the exterior wall and soffit areas of buildings. In all applications, refer also to the specific manufacturer's instructions for installation.
1.2 This practice covers aspects of installation relating to effectiveness and durability in service.
1.3 The various application systems are located in the following sections of this practice:
Substrate, Surface Preparation
Section 8
Application of Horizontal Siding
Section 9
Application of Vertical Siding
Section 10
Application of Soffits and Fascia
Section 11
Special Details
Section 12
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.Note 1—There is no known ISO equivalent to this standard.
