2.18.2 – INTERIOR DRYWALLDrywall should be installed in the same manner on aLogix wall as on a stud wall, with the following timesaving exceptions: All webs (studs) are on 8 inch (203 mm) centersfrom floor to ceiling for easy attachment of anytype of interior wall finish. The butt joints of the sheetrock do not need tofall on webs (studs) as the foam provides solidG U I D Ebacking wherever the joints fall. However, theedge of sheetrock panels should not exceed morethan 4” from webs.I N S T A L L A T I O N A foam-compatible adhesive can be used toeffectively fasten the sheetrock to the Logix wallalong with screws. Always make sure to verifythe local code for types and spacing for sheetrockfasteners. Typically, adhesive alone is not allowedas a fastener of sheetrock, but again check withlocal building codes.Many local building codes require the application of 1/2inch (13 mm) drywall or other suitable thermal barrierin any living space even though the EPS foam has a fireretardant component. Always verify local building coderequirements.www.logixicf.comBuild Anything BetterREPRINTED 20162–88 Rev. Nov 23/15

2.18.2 – INTERIOR DRYWALL CONTINUEDNon-habitable spaces such as crawl spaces, attics, andother types of hidden areas typically do not require athermal barrier (drywall).Embedded furring tabs are fixed at each corner of theLogix 90 corner forms for solid sheetrock fastening at allI N S T A L L A T I O NG U I D Ecorners.www.logixicf.comBuild Anything BetterREPRINTED 20162–89 Rev.

2.18.3 – EXTERIOR SIDINGSiding material of some kind must be installed over theEPS foam to protect it from the UV rays of the sun. Foamleft exposed to the sun will degrade on the exposedsurface by slowly breaking and getting “dusty”.I N S T A L L A T I O NG U I D ENOTE: When using Logix Platinum Series care shouldbe taken to protect exposed foam surfaces fromreflected sunlight and prolonged solar exposure untilwall cladding or finish material is applied. Shadeexposed foam areas, or remove sources of reflectivesurfaces, where heat build up onto exposed foammight occur. For more information refer to BASFTechnical Leaflet N-4 Neopor, “Recommendationsfor packaging, transporting, storing and installingbuilding insulation products made from Neopor EPSfoam.” (The BASF Technical Leaflet is attached toevery bundle of Logix Platinum forms delivered to ajob site).Metal and vinyl siding can be installed directly over thetop of the EPS.Although air guns can be used, Logix recommends theuse of screw guns when attaching exterior siding. Alwaysfollow manufacturer’s recommendations and local codesto determine the size and spacing of fasteners for allsiding products.Any type of siding that is used on a typical wood-framedbuilding can be used on a Logix building.The siding channel stock around doors and windowscan be fastened to whatever type of buck material waschosen, in a similar fashion as wood framed building.www.logixicf.comBuild Anything BetterREPRINTED 20162–90 Rev.

2.18.5 – WOOD SIDINGAny wood siding can be attached to the Logix wall in thesame manner as to a traditional framed building. Thespacing of the web studs on 8 inch (203 mm) centersallows for industry standard spacing of fasteners.Typically, screws are used for attaching wood siding oreven half-log siding to the Logix wall.Although air guns can be used, Logix recommends a screwgun with screws in clips (Quik Drive). This is usually thefastest method for applying wood siding. Always followG U I D Emanufacturer’s recommendations and local codes todetermine the size and spacing of fasteners for all sidingproducts.I N S T A L L A T I O NA good practice for installing wood siding on a wall, isto apply the siding over vertical 1 inch x 2 inch (25 mm x51 mm) wood nailing strips with a screen at the bottom.The screen keeps insects out while the space allows airto circulate behind the siding. The air circulation helpsequalize the moisture content in the wood siding, whichmakes for much more dimensionally stable siding andlonger lasting application.www.logixicf.comBuild Anything BetterREPRINTED 20162–92 Rev.

2.18.6 – EIFSThere are now acrylic-based stucco products available thatare more flexible and easier to work with than traditionalcement-based stucco. Collectively these products areknown as EIFS (Exterior Insulation Finish Systems) andalmost always require an EPS substrate.Because Logix blocks are made with EPS, they are anatural fit for EIFS finishes. In addition, the webs in Logixblocks are embedded 1/2 inch (13 mm) deep in the EPSG U I D Efoam to comply with EIFS manufacturer requirements.It is important to follow the EIFS manufacturer’sI N S T A L L A T I O Napplication procedures.www.logixicf.comBuild Anything BetterREPRINTED 20162–93 Rev.

2.18.7 – TRADITIONAL STUCCO(CEMENT-BASED)Logix walls will accept traditional cement-basedstucco product. Although air guns can be used, Logixrecommends a screw gun when attaching the wire lathmesh to Logix walls. Use screws with a wide head orscrews along with washers to best hold the mesh in place.Consult local building codes for vertical and horizontalfastener placement requirements. The center-to-centefastener spacing requirements for nails and staplesmust be followed for screws as well. Again, check withG U I D Elocal codes for all specific requirements relating to theapplication of stucco over EPS insulation.I N S T A L L A T I O N2.18.8 – CEMENT COMPOSITE SIDINGRecently the new cement fiber siding products havegained popularity. This type of siding can usually befastened directly to the Logix webs. Although air gunscan be used, Logix recommends a screw gun to fasten flatheaded exterior screws at 16 inch (406 mm) centers. Thescrews pull the siding in tight and hold the siding securelyin place. Some manufacturers may require the sidingto be strapped out to allow air space behind. Verticalor shake patterns will require strapping for fastening.Always follow manufacturer’s recommendations and localcodes to determine the size and spacing of fasteners forall siding products.Check with your siding manufacturer for specificrequirements.www.logixicf.comBuild Anything BetterREPRINTED 20162–94 Rev.

2.18.10 – BELOW GRADE WATERPROOFING,DAMPPROOFING & PARGINGThere are many methods available to protect the “belowgrade” and the “just above grade” areas of the exteriorof your building.Dampproofing is used on concrete or masonry surfaces torepel water in above grade walls. The 2.75 inch (70 mm)and thicker foam panels of the Logix insulated concreteforms acts as dampproofing, therefore, no additionaldampproofing treatment is required.G U I D ENOTE: Although dampproofing above grade walls is nottypically required, check with local building codesI N S T A L L A T I O Nfor dampproofing requirements.www.logixicf.comBuild Anything BetterREPRINTED 20162–96 Rev.

2.18.10.1 – BELOW GRADEWATERPROOFINGLogix recommends a rubberized “peel and stick”waterproofing membrane. The membrane is appliedvertically to the wall from grade level down to andoverlapping the top of the footing. It is recommendedto use protection board (1/2 inch EPS or EXP foam sheetsor similar) to prevent damage to the waterproofingmembrane during backfilling.Free flow drainage material with a maximum fluid densityof 30 pcf (480 kg/m3) is recommended, i.e., sand or sand-NOTE: Membrane should be installed within one weekprior to backfill being placed. Sunlight and hightemperatures may cause the membrane to beginto “sag” which may cause wrinkles in the materialwhich may result in tears or punctures duringthe placement of the backfill material. Shouldyou choose to use one of the many other typesof waterproofing available be sure to followthe manufacturer’s recommended installationprocedures.STEP 1: Prep the wall and footing area to be covered byremoving dirt and debris.STEP 2: Snap chalk lines for the “grade” line.STEP 3: Measure the height from grade line to footing.Add enough length to cover the top of thefooting and cut pieces of membrane to length.www.logixicf.comBuild Anything BetterREPRINTED 20162–97 Rev.
