The dimensions depicted above do not supersede the requirements of local construction codes.The distances depicted above were calculated based on the structural properties with the followingfactors being taken into consideration: sheet deflection, potential wind load, potential snow load,hail and application load according to usual construction practice.2. When designing a new roof, it is strongly recommended that the slope be above 10% (5.7°). (Consultyour local PALRAM representative when recovering an existing greenhouse whose slope is shallowerthan this value).3. The recommended maximum panel length is 7.0 m. The recommended maximum distance betweenthe edge and first purlin is 900 mm or the value dictated by the design engineer. (See drawing onpage 5- Figure 8b).Calculate the number of sheets as follows:61326 8.041 - Divide the length of the roof (the length of the gutter) by the effective width of the sheet.2 - Calculate the required length of the sheet (to be no greater than 7.0 m) according to purlin to purlindistance plus the required extension beyond first and last purlin and overlap distance, if exists.2

SUNTUF PlusINSTALLATION INSTRUCTIONSCHandling and Storage:1. PALRAM corrugated sheets must be transported and stored horizontally on aflat, sturdy pallet whose dimensions are equal to or larger thanthe sheets themselves. The sheets should be secured and fastenedto the pallet. It is possible to store sheets of smaller dimensionson top of larger sheets of the same type. (Never store sheetsof larger dimensions on top of smaller sheets!) SUNTUF Plus must bestored in a cool and shaded location.2. Important: Never cover the pallet with, or place on the pallet, materials thatare good conductors of heat (e.g. metal, pipes, clear or dark objects).3. In cases where it is necessary to store the pallet outdoors, cover it with awhite opaque polyethylene sheet, card board, or any other material thatdoes not absorb or conduct heat. The total pallet must be covered.Figure 3DCutting:It is possible to cut SUNTUF Plus corrugated sheets using a circularsaw with small teeth, rotating at a high speed, taking care toadvance the saw slowly. It is also possible to use a portable electricsaw(Jig Saw) or sheet metal shears. In any case, it is importantto support the sheet in the vicinity of the cut and clean awaythe dust and debris generated by cutting.Figure 4EDrilling:1. Drilling should be carried out with a drill bit intended for metal. The holediameter must be 2 mm greater than the diameter of the screw to be used.It is important to support the sheet in the vicinity where the sheet is beingdrilled. The dust generated by drilling must be cleared away before theinsertion of the screw.2. Special attention should be given to drill all the required holes perpendicularto the face of the material.Figure 590 oFChemical Resistance (compatible sealants and adhesive materials):1. SUNTUF Plus sheets are resistant to a variety of chemicals and exhibit limitted resistance to a second group ofchemicals. A third group of chemicals will attack and cause damage to the sheet. The degree of damage will dependon the severity of attack and time of exposure.2. Choose only sealants and adhesives which are compatiable with SUNTUF Plus (see paragraph G).3. Beware of installing the sheets on wet paint, or other uncompatible materials, which may damage the polycarbonatsheets.4. Use of sealants or adhesives not included in the recommended list must receive the Manufacturer's explicit approval.This can be obtained through your distributor. Use of materials not on the list, or which have not received theManufacturer's explicit approval, may harm the sheet and will void all warranties and any responsibility of themanufacturer for the performance of SUNTUF Plus!!5. Your local distributor can provide additional information and forward materials for evaluation of their compatabilitywith SUNTUF Plus.61326 8.043

Corrugated sealing strip closure should be used to preventthe entry of water, wind, insects or other small animalsbetween installed sheets. A seal between the sheet andthe edge purlin of the roof can be created using a sealingstrip in the form of the profile. It is held in place by thesame screw used to fasten the sheet to the purlin. Thesealing strip should be manufactured from cross-linkedpolyethylene foam (XPE)3. Sealing strips between overlapping sheets should be usedwhere the pitch of the roof is less than 15%. Only butylrubber strips should be used. The strip should be placedbetween overlapping sheets along the length and widthof the overlap at both edges. In cases where penetrationof wind or fumes must be prevented, a sealing strip shouldbe used irrespective to roof slope. Wherever a sealing stripis inserted, a fastening sheet to sheet tightening screwshould be used.Shaped foam polyethylenetop and bottom (PE) sealing strips.Figure 6aButyl Rubber Sealing StripFigure 6cSilicone sealant.Figure 6bWARNING - Do not use materials which are not recommended by Palram.Specifically, polyurethane foam should not be used as installion foamwith SUNTUF Plus. Contact with this material will render the sheetsfragile. When in doubt, consult your Palram distributor.HUse of Shading Compounds:1. It is possible to apply shading compounds on SUNTUF Plus sheets.2. Use only recognized commercial brands, confirmed to be compatible with polycarbonate. Do not apply dubious mixturesthat may contain incompatible components, which will attack and damage the sheets.3. In case of doubt, consult your SUNTUF Plus distributor, who can advise you on the proper use of shading compounds.4. You can ask for recommendations on compatible formulations that were tested and confirmed for use by PALRAMIndustries. Note that all the recommended formulations are water-soluble and will eventually be washed away by rains.5. Shading compounds should be easily removed using a strong water jet in conjunction with vigorous brushing with asoft bristle brush, or wiping with soft cotton rags.61326 8.044

SUNTUF PlusINSTALLATION INSTRUCTIONSIPositioning of Sheets:1. Only one side of a SUNTUF Plus sheet is UV protected*. Thisside must always face out toward the sun. The UV protectedside is indicated by a sticker or polyethylene strip along thelength of the sheet.The sticker or polyethylene strip must beremoved immediately after the sheet is installed.2. The sheets should be laid down on the roof or set upon thewall against the primary direction of wind and rain.3. Do not step on the panels between purlins.4. Stepping ladders and other devices required for safe workshould be used.5. Never leave panels unattended until all the required screwshave been tightened.6. SUNTUF Plus sheets are lightweight. The sheet can be rolledin a direction perpendicular to the length of the corrugationsfor the purpose of lifting them to the roof.* Except for SUNTUF Plus UV2 which is manufactured with co-extruded UVprotection on both sided when a special order has been placed.Figure 7aFigure 7cDirection of Wind and RainLay Sheets against Wind DirectionFigure 7bFigure 7dJOverlap:1.

SUNTUF PlusINSTALLATION INSTRUCTIONSLRoof and Wall Fastener Location:1. A fastening screw should be inserted into atleast every third corrugation valley at eachinternal purlin.2. Along the edge purlin, the screws are to beinserted into alternate corrugation valleys.3. Along the length overlap, the screws are tobe inserted into the overlapping corrugationcrest on top of each purlin.4. A hole must be pre-drilled into each screwlocation. The diameter of the hole must be2 mm larger than that of the screw.Positions for fastening roof or wall screws at internal purlin.Figure 10aPositions for fastening roof or wall screws at edge purlin.Figure 10b19 mm washer19 mm washer5. The screws should be tightened with an electricscrewdriver with an adjustable clutch, takingcare not to over-tighten. Excessive tighteningmay harm the sheet and cause prematurefailure.6. Sheet-to-sheet stitching fasteners arerecommended along the length of overlappingcorrugations between the purlins, at least 2units at every span. (Par. M. Sheet-to-sheetstitching fasteners, p. 6)19 mm washerGreca ProfileFigure 10cOmega ProfileFigure 10d25 mm washerM Screws, Washers and Gaskets:1. General Recommendations: For optimal long-term maintenancefree service, PALRAM strongly recommends the use of heavydutycorrosion resistant screws, and special metal washerswith profiled 4 mm (at least) thick EPDM rubber gaskets*,19 mm (crest) or 25 mm (valley) diameter (in Greca profilboth crest and valley with 19 mm), to fasten the sheets tothe supporting structure and seal the fastener’s hole. (fig.11a, b).2. Use of self-tapping screws with pre-drilled holes or self-drillingscrews is recommended. For wooden purlins, a special woodscrewshould be used. (See Figures 11c, d, e on side.)19mm washer/gasketFigure 11a25mm washer/gasketFigure 11b3. The screw placed into corrugation crest should be 6.3 x 38mm (1/4 x 11/2 in.) or a #12 or 14 gage screw. Screwsplaced in a corrugation valley should be 6.3 x 25 mm (1/4x 1 in.). Each screw should be fitted with a conical corrosionresistant metal washer at least 1 mm (0.04 in.) thick and aspecial EPDM gasket (fig. 11a,b). The screw should be tightenedmoderately without deforming the washer and rubber gasketor distorting the corrugation.4. Special attention should be given to the insertion of the screwsperpendicular to the material face. Oblique insertion coulddamage the sheet and/or result in leaks.

SUNTUF PlusINSTALLATION INSTRUCTIONSNSheet-to-Sheet Stitching Fasteners:1. Stitching fasteners are used to create acomplete tightening between overlappingsheets, between purlins. When the slopeof the roof is less than 15%, it is necessaryto insert such a fastener every 40 cm.Where the slope is greater than 15%,the spacing is every 50 cm. It isrecommended to use 1 /4” x 3 /4” self-tappingscrews, without the need for prior drillingof a hole.2. Top & bottom length overlap strengtheningprofiles (Fig. 14) are also serving as sheetto-sheetstitching elements, with additionalmid-span screws.Sheet-to-sheet fastening screwbetween overlapping corrugations(detail), for Omega profil.Figure 13aSheet-to-sheet fastening screwbetween overlapping corrugations(detail), for Greca profile.Figure 13bFigure 14OAdditional Accessories:1. Purlins for Condensation Collectiona) It is possible to build the greenhouse (consult yourgreenhouse supplier) utilizing special purlins of omegadesign that aid in condensation collection and preventcondensation drip from the purlins. Care must be takento construct the greenhouse with a devise that will carryoff the collected condensation at the edge of the purlins.b) An aluminum collecting profile will be installed ontop of every supporting truss or beam in the greenhouse.Its purpose is collecting and draining the condensedwater gathered in the Omega purlins’ channels, leadingthem into the side gutters.
