1、Designation: C716 06 (Reapproved 2015)Standard Specification forInstalling Lock-Strip Gaskets and Infill Glazing Materials1This standard is issued under the fixed designation C716; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th

2、e year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers installation procedures forlock-strip gaskets that comply with Specification C542

3、and forinfill glazing materials in lockstrip gasket glazing applicationsused in building walls which are not more than 15 from avertical plane. The prime performance considerations areweathertightness against air and water infiltration, and struc-tural integrity under wind loads.1.2 The values state

4、d in SI units are to be regarded asstandard. The values given in parentheses are provided forinformation only.1.3 The committee with jurisdiction over this standard is notaware of any comparable standards published by other orga-nizations.2. Referenced Documents2.1 ASTM Standards:2C542 Specification

5、 for Lock-Strip GasketsC717 Terminology of Building Seals and SealantsC963 Specification for Packaging, Identification, Shipment,and Storage of Lock-Strip GasketsC964 Guide for Lock-Strip Gasket Glazing3. Significance and Use3.1 This specification can be referred to in contract docu-ments as a metho

6、d and workmanship standard for the installa-tion of lock-strip gasket glazing systems. See also relatedstandards (Specifications C542 and C963, Guide C964, andTerminology C717).4. Installation4.1 Inspection of ComponentsBefore installing gaskets,the installer shall check the mounting frames to see t

7、hat theyare within specified dimensional tolerances and not out-of-square or plane, and check all gaskets for type, dimensions, anddefects such as misalignment at molded corners and damagedlips. Installation shall not proceed until corrections have beenmade.4.2 Environmental ConditionsMaximum effici

8、ency andsealing capability of gaskets is achieved in a clean, dry, warmenvironment, with the gasket kept resilient during the entireinstallation process. During cold weather the use of temporaryenclosures around the units to be glazed or paneled willfacilitate temperature control and also aid in kee

9、ping opengasket channels clean and dry.4.3 Preparation and Conditioning of GasketsLock-stripgaskets require conditioning prior to installation in order torestore maximum resiliency and remove deformations afterprolonged storage in a coiled or stressed position. Gaskets shallbe unpacked from their co

10、ntainers and conditioned for 24 h ina temperature not lower than 21.1C (70F) by being placedflat or hung on racks to permit recovery of their originalshapes. Racks shall be free of rough surfaces, projections,sharp edges, and other conditions that could damage thegaskets. When the ambient temperatur

11、e is 10C (50F) orbelow and a heated space is not available, gaskets shall beheated by other means to remove deformations and provide ahigh degree of flexibility and resiliency. This may be done bywarming them in hot water or heated containers. Gaskets shallnot be heated by being draped over heated u

12、nits or placed indirect contact with a flame or fired heating device. Theinstallation of glass, panel, and lock-strip shall be completedwhile the gasket is still warm and pliable and with the gasketchannels clean and dry.4.4 Use of ToolsTo minimize the possibility of damage,sharp or pointed tools or

13、 implements such as screwdrivers orputty knives shall not be used on lock-strip gaskets. Suitablegasket installation tools, such as nonmetallic spatulas andengineered lock-strip insertion devices, are available from thegasket manufacturer.4.5 Use of LubricantsIf necessary a lubricant may beapplied t

14、o the contact surfaces of the gasket to ease theinstallation and help prevent damage to the gasket, glass, orpanel. The lubricant shall be nonstaining, nontoxic,noncorrosive, chemically stable, compatible with all contactcomponents, easily removable from exposed surfaces by dry1This specification is

United States1wiping or with water, and acceptable to the manufacturer of thesupporting frame, panel, and gasket.4.6 Use of Supplementary Wet SealantsThe use of supple-mentary wet sealants in conjunction with lock-

18、strip gasketinstallations is only required under certain conditions. Such acondition would occur when the outer lip of the gasket extendsover a butt joint in the supporting frame. The void formedbetween the gasket and frame shall be sealed at the time ofinstallation with a wet sealant. However, the

19、sealant may beomitted if the system is designed to drain any water that entersto the exterior, and the omission of a wet sealant is agreeableto the purchaser and seller. Another condition would be at fieldbutt joints in gaskets. Such joints require the use of a sealantinstalled in, rather than on to

20、p of, the joint at the time of thegasket installation. The wet sealant used, as well as the sealantmanufacturers requirements for cleaning and priming thesurfaces to be sealed, shall be compatible with the componentsin contact with it and acceptable to the manufacturers of thecomponents. The use of

21、wet sealants to remedy a defective ordamaged gasket or improperly fabricated supporting frameshall not be permitted, unless agreeable to the purchaser andseller.4.7 Installation of Single-Opening Gasket Systems:4.7.1 H-Type GasketInstall the upper gasket corners first,and then install the lower gask

22、et corners onto the supportingframe. To avoid slippage, engage both horizontal and verticalmembers for about 304.8 mm (1 ft) in both directions from thecorners, and work the gasket until the web is snug against headand jambs and the corners are square. Then work the remainderof the gasket onto the s

23、upporting frame by starting from eachcorner and working towards the center of each side, makingsure the gasket web is firmly seated against the frame and thatthe sealing lips are not curled under, particularly at the corners.Pull each corner of outer flange about 6.4 mm (14 in.) awayfrom the support

24、ing frame with thumb or nonmetallic spatulaand then release to ensure uncurling any corner lips hiddenfrom view.4.7.2 Reglet-Type GasketInsert the upper gasket cornersfirst, and then install the lower gasket corners into the grooveor reglet of the supporting frame, seating them firmly with aresilien

25、tly faced hammer and a wooden or metal block havingsmooth, rounded edges and corners. Then, on each side, insertthe gasket into the groove at the center of each side workingfrom the center to the corners and from the corners to thecenter, equalizing the crowd over the length of each side untilthe li

26、ps are firmly and continuously seated against the support-ing frames.4.8 Installation of Multiple-Opening Gasket Systems (SeeFigs. 1 and 2):4.8.1 Unsupported Vertical Ladder AssemblyLaterally un-supported vertical ladder type installations as illustrated in Fig.2, where the vertical load of a light

27、of glass is transferredthrough the gasket web to the light below, with lateral supportat the jambs, are not recommended. Refer to Guide C964 for adiscussion of the disadvantages of this type of system.4.8.2 Unsupported Horizontal Ladder AssemblyMark onthe head and sill frame members the exact locati

28、on of thecenter line of the vertical gasket muntin. Install the jambsection first, then work along the head and sill to the firstmuntin. Align each gasket muntin with the center lines markedon the head and sill. Install the glass or panel. The installationof setting blocks and edge spacers can be pe

29、rformed asdescribed in 4.10. Then insert the lock-strip at the sill and head,running to within a few inches of the first gasket muntin.Continue the procedure by installing the next glass or panel.Insert the lock-strip into the muntin first and continue with theinsertion of the lock-strip at the head

30、 and sill members. Repeatthe procedure until all glass or panels are installed.4.8.3 Supported Vertical Ladder AssemblyAlign and se-cure the gasket horizontal muntins to the corresponding sup-porting structural members. The gasket muntins are held in lineby the structural supporting muntin members w

31、ith the entireladder gasket unit completely supported during the installationprocedure.4.8.4 Supported Horizontal Ladder AssemblyMount thegasket to the peripheral frame first. Then align and secure thevertical gasket muntins to the corresponding structural support-ing members. Vertical spacer shims

32、are not required betweenthe glass or panel edge and the gasket web.4.8.5 Grid AssemblyA grid assembly is a combination ofthe horizontal and vertical ladder assemblies. Supported gridgaskets are mounted to the corresponding frame membersfollowing the procedures noted under 4.8.3 and 4.8.4.4.9 Install

33、ation of Stick SystemA proprietary stick systemshall be installed in accordance with the curtain wall manufac-turers instructions.4.10 Installation of Glass or Panel into GasketInspect,clean, and dry the gasket as required and replace, if damaged,before proceeding with the glazing or paneling operat

34、ion. Ifnecessary, a lubricant recommended by the gasket manufac-turer can be used to aid insertion. Lubricate the surface of theexterior flange on the lock-strip side of the gasket channel thatis to receive the glass or panel. Beginning approximately 152.4to 203.2 mm (6 to 8 in.) above the bottom, o

35、pen the channellips and engage both lower corners of the glass or panel into thegasket sides and then lower it carefully into the sill channel ofthe gasket. Maintain the plane of the panel as close to the planeof the opening as possible. Insert a nonmetallic spatulabetween the edge of the glass or p

36、anel and the sealing lip onFIG. 1 Gasket SystemsC716 06 (2015)2each side, starting at the bottom of the opening. Proceedupward with both spatulas at the same time, while simultane-ously pushing the glass or panel lightly inward. Use care toprevent cutting of gasket-sealing lips. When the glass or pa

37、nelis in jamb channels to within 50.8 to 76.2 mm (2 to 3 in.) ofuppercorners, begin at the center of the head and work outwardeach way to engage the head channel. Then, using two spatulas,lift gasket corners over the edge of the glass or panel. Centerthe glass or panel in the gasket for uniform edge

38、 coverage onboth sides of the installation. At this time install properly sizedsetting blocks, if required, by lifting the glass or panel andplacing them at the quarter points. Lower the glass or panelonto the blocks, being careful not to displace them. Settingblocks under panels are optional but ar

39、e required for laminated,insulating, annealed tinted, and reflective glass. The use ofsetting blocks for other types of glass products shall be inaccordance with the glass manufacturers recommendations. Ifnecessary, edge spacers may be installed at this time tomaintain uniform edge clearance and to

40、preclude lateraldisplacement of the glass or panel.4.11 Installation of Lock-StripAs soon as the glass andpanels are in place, install the lock-strip so that the assembly issecure and the gasket channel is sealed. Cut lock-strip for thesill to a length approximately 50.8 to 76.2 mm (2 to 3 in.)longe

41、r than the sill opening dimension. Lubricate the lock-stripand lock-strip cavity. Thread the lock-strip into the eye of theinsertion tool. Start installation of the lock-strip at the sill,trying to keep it under compression instead of tension andleaving an excess of lock-strip at both ends. Repeat t

42、hisprocedure for jambs and head. To avoid any later creep ordrawback of the lock-strip from the corners, trim the lock-stripends approximately 3.2 to 6.4 mm (18 to14 in.) longer than thelock-strip cavity using garden pruning shears or diagonalcutters, and crowd the lock-strip into place using a nonm

43、etallictool. Either a mitre or square butt joint is acceptable. Whenmolded lock-strip corners are used, install them first and formbutt joints with the lock-strip in compression between thecorners.4.12 Completing the InstallationTo straighten thesightline, tap the gasket against the frame using a cl

44、ean, smoothblock of wood. Push the lock-strip into the cavity with aspatula wherever complete insertion was not accomplished.Wipe off excess lubricant. Inspect and rectify any curled-underlips. Contact of the gasket with the frame and panel or glassshall be continuous and positive against smooth fla
