(6.4 mm) clearance between the ends of panels and trim and any receiver such as J-channels and corner poststo allow for thermal expansion. If installing during weather colder than 40F (4.4C), increase th

Substrat

31、e, Surface Preparation8.1 Weather-resistantWater-resistive BarrierVinyl siding must be installed over a weather-resistantwater-resistive barriersystem that includes (1) a continuous weather-resistantwater-resistive material, and (2) properly integrated flashing around allpenetrations and where vinyl

32、 siding interfaces with other building products. Refer to the vinyl siding manufacturers installationinstructions and the minimum requirements of the local building code for specific product applications and requirements.8.2 All caulking to prevent moisture penetration must be done before siding app

33、lication. Do not use caulk where it could restrictthe normal expansion of the vinyl siding.8.3 Apply vinyl siding over sheathing or other solidrigid surface that provides a smooth, flat surface. Do not apply vinyl sidingdirectly to studs without sheathing. If permitted by the vinyl siding manufactur

34、er, a contoured foam underlayment fitted for thespecific style of vinyl siding is permitted to be utilized. Apply over wood furring strips when the underlying surface is uneven.8.4 Drive fasteners into framing or furring. Driving of fasteners directly into sheathing or existing siding is permitted i

35、naccordance with the siding manufacturers instructions, where substantiated by windload testing conducted in accordance withSpecification D3679.8.5 On existing structures, secure any loose boards, replace any rotted ones, recaulk around windows, doors, and other areasas necessary to protect from moi

36、sture penetration prior to the installation of siding or accessories. Use furring as needed to createan even surface.8.6 FlashingRefer to Practice E2112 for installation of flashing around windows, doors, penetrations and points of interfacebetween the vinyl siding and other building components. If

37、available, also refer to the instructions provided by the manufacturerof the window, door, or other object that will penetrate the siding.8.7 FurringMasonry and uneven surfaces, as examples, require wood furring strips nominal 1 by 2 in. (25.4 by 50.8 mm)applied vertically and typically spaced 16 in

38、. (406 mm) on center for horizontal siding and applied horizontally and typicallyspaced 12 in. (305 mm) on center for vertical siding.9. Application of Horizontal Siding9.1 General RequirementsVinyl siding and accessories expand and contract as much as 12 in. (12.7 mm) over a 12 ft (3.65m) length wi

39、th changes in temperature. For this reason adhere to the following provisions:9.1.1 When applied, vinyl siding products must be attached “loosely,” leaving approximately a 132-in. (0.8-mm) space betweenthe vinyl and the fastener head or crown to permit thermal movement. (See Fig. 6.)9.1.2 Center fas

40、teners in slots of siding and accessories to permit possible expansion and contraction. (See Fig. 7.) If a nail slotdoes not allow centering/securing into framing, furring, or other permitted nailable surface, use a nail hole slot punch to extendthe slot and allow centering of the fastener.9.1.3 Do

41、not face nail siding panels. (See Fig. 8.)9.1.4 Allow clearance at panel ends for thermal expansion between corner posts, J-channels, and other receivers in accordancewith 6.2.9.2 Installation of AccessoriesAccessories, including starter strips, corner posts and door/window trim, are installed prior

42、 toapplication of the siding, adhering to the provisions of 9.1 and those which follow.9.2.1 Starter StripDetermine the lowest point along the area to receive siding and install starter strips located so that thebottom edge of the initial course of siding will be on a level line and typically approx

43、imately 14 in. (6.4 mm) below that point.Allow space for corner posts, J-channels, etc., and keep ends of starter strips 14 to 12 in. (6.4 to 12.7 mm) apart. Space fastenersnot more than 10 in. (254 mm) apart, centered in nail slots.9.2.1 Corner PostsOutside and inside corner posts will start 14 in.

44、 (6.4 mm) below the top, and end 34 in. (19.1 mm) belowthe bottom edge of the first course of siding which will be installed later.Attach each leg of the corner posts with fasteners, spacednot over 12 in (305 mm) apart centered in nailing slots except the top fastener that is located at the upper en

45、d of a nailing slot.9.2.1.1 If more than one length of corner post is required, lap the upper piece over the lower piece by cutting away 1 in. (25.4mm) of the nailing flange on the top piece. Lap 34 in. (19 mm) allowing 14 in. (6.4 mm) for expansion. (See Fig. 9.)FIG. 6 Attachment of Vinyl SidingD47

46、56 1359.2.1.2 As an alternative for inside corners, install two J-channels with the web of one abutting the adjacent wall and the webof the other J-channel abutting the shorter outer flange of the first J-channel. Attach as specified in 9.1.1.9.2.2 Starter StripDetermine the lowest point along the a

47、rea to receive siding and install starter strips located so that thebottom edge of the initial course of siding will be on a level line and typically approximately 14 in. (6.4 mm) below that point.Allow space for corner posts, J-channels, etc., and keep ends of starter strips 14 to 12 in. (6.4 to 12

48、.7 mm) apart. Space fastenersnot more than 10 in. (254 mm) apart, centered in nail slots.9.2.3 Door/Window Trim:9.2.3.1 Install flashing around windows and doors in accordance with 8.1 and 8.6 before installing trim.9.2.3.2 J-channel is installed on each side and the top of door and window frames, a

49、nd under window sills. Always install thebottom J-channel first, followed by the side channels, and then the top channel.9.2.3.3 Extend the bottom and top J-channel the length of the window frame plus the width of the visible face of the sideJ-channels (typically 34 in. (19 mm) on each side. Extend the side J-channels the height of the window or door frame plus thewidth of the visible face of the top and bottom J-channels.9.2.3.4 In the bottom J-channel, cut a notch in the web at each end the width
