sTORagE & LabELLINg

This manual sets out the instal-lation methods for alkorPLAN® membranes.

1. STOrAGEThe rolls are delivered to site on pallets. These should be stored in a dry place or, if this is not poss ib le , protected aga inst exposure to damp, rain, frost and snow.

2. LABELLINGA l l r E N O L I T r o o f i n g m e m b r a n e s a r e l a b e l l e d w i t h t y p e n u m b e r, b a t c h number, width and thickness. A record should be kept of this label so that, in the event of a claim, it can be checked against laboratory test samples. Batch samples are kept of all material manufactured.

CHEMICALCOMPATIBILITYPlease check the data sheet fo r genera l i n fo rmat ion on the chemical compatibi l i ty of alkorPLAN® roofing membranes.

INSULATIONAs a general rule all synthetic insulation boards must have a separation layer either included during manufacture or laid before installing the membrane.

BITUMEN PrODUCTSalkorPLAN® must not be laid in direct contact with any bitumen product. A separation layer must be used.

OTHEr PVC MEMBrANES Or OTHEr FLExIBLE PVC PrODUCTSalkorPLAN® must not be laid in direct contact with, or welded to other plasticised PVC mem-branes. As a genera l ru le , alkorPLAN® membranes should not be laid over old synthetic or rubber membranes. These membranes should be removed.

COMpaTIbILITy


CLEaNINg

CLEANINGCleaning is best done with a rag. I f dirt is to be removed, usea spray w i th wate r and a diluted detergent with water or alkorPLUS®cleaner.Ifbituminousproducts have to be removed from the membrane only alkorPLUS® cleaner may be used.


HOT aIR WELDINg, TEMpERaTURE & TEsTINg

HOT AIr WELDINGP re l i m i n a r y c h e c k s e n s u r t h e n o z z l e i s c l e a n a n d open across its entire width. Ensure the f i l ter is c leaned.

TEMPErATUrE Adjust the welding temperature in the hand held welding gun to allow a flow of hot air that induces a slow charring on a piece of wood.

I f the we ld ing gun has aninternal heat setting with digital thermometer display, set this to 480 deg C and allow the gun ten minutes to heat up. This may be adjusted depending upon ambient conditions.

WELD TESTINGMake a weld sample to test the material you will be using and to test that the settings on your welding gun are correct.

Check the weld test sample with adestructivetest.(seetestingonPage13)


CabLEs & WELD OVERLaps

CABLESTo avoid a voltage drop, never use an excessively long exten-sion cable or share a power cable with others.To prevent damage and fire, never use an extension cable that is still coiled on a roll.

WELD OVErLAPSAs a general rule, alkorPLAN® weld overlaps must be 100 mm o n m e c h a n i c a l l y f a s t e n e d systems, 80 mm on adhered systems and 50 mm on ballasted systems. It is important tohavea constant weld width of min. 30 mm.


WELDINg gUN & WELDINg CHECK

WELDING GUNThe weld is now carr ied out with the hot air welding gun held between the sheets of alkorPLAN® to be welded at 45° to the welding line.

Roll the weld with the silicone roller held about 1 cm from the nozzle of the gun. The operative has three factors at his control:

The HEAT of the welding gun

The SPEED at which the welding gun is moved

The PrESSUrE of the roller on the two alkorPLAN® sheets

WELDING CHECKOn completion of the weld the operative must check its integrity by drawing a weld checking probe down the length of the weld. The probe wil l f ind any unwelded areas which must be re-welded immediately with hot air.


sEaM sEaLER

SEAM SEALErWhen an area of welding is completed and checked the alkorPLAN® seam sealer must be appl ied. Ensure that the membrane is clean and dry and dust free before the application of the seam sealer. It is goodpract ice to apply the seam sealer as soon as possible after the welding is completed and checked although care must be taken not to apply seam sealer to areas that will have further membrane welded to them.


aUTOMaTIC WELDINg & WELD TEsT

AUTOMATIC WELDINGThere are var ious automatic w e l d e r s o n t h e m a r k e t . The manufacturer’s represen-tat ives wi l l be avai lable, on request, to set up the machines and train operat ives in their use - especially when buying a new machine. Please check with our technical dept. for the required weld widths approved for the various machines.

WELD TEST When hot air welding with hand or automatic tools it is good practice to carry out a peel test before every welding session on a 50 mm wide sample weld, so as to ensure that the tool settings arecorrect.Iftheweldhasbeenmade correctly the membrane will give way before the weld. A 50 mm wide weld should support a weight of at least 15 kgs.


sOLVENT WELDINg& sOLVENT bRUsH

SOLVENT WELDINGalkorPLAN® can also be solvent welded but this can only be used for long seams, NOT for any detail work & strict criteria must be obeyed before the use of solvent welding can be approved. •The a i r temperature must

be above 5 deg centigrade

•Relativehumidity<60%

•I t may on ly be used fo r welding new alkorPLAN®

•ThealkorPLAN® must be clean, dry & dust free & laying flat.

Check the expiry date of the solvent. Do not use old solvent or solvent that has been opened at an unknown date. Do not stand the solvent brush applicator on the membrane.

SOLVENT BrUSHThe solvent is applied using a brush applicator between the sheets to be welded. The brush applicator is moved in a circular motion applying the minimum amount of solvent to both sheets being welded.


sOLVENT WELDINg CONT.

SOLVENT WELDING CONT.Immediately following the brushapplicator, a rolled rag is used to apply pressure to the welded joint, smoothing it out and expelling any excess solvent.

As the welding progresses a weight (e.g.sandbag)isplacedalongthelineof the weld to give a short period of constant pressure until the adjacent welded area is completed. The weld must be checked as before, using the weld checking probe and any unwelded areas sealed using hot air welding techniques.

Aweld testmustbe included. It isgood practice to carry out a peel test before every welding session on a 50 mm wide sample weld, to ensure that the welding process is correct.

If the weld has been made correctly, the membrane will give way before the weld. A 50 mm wide weld should support a weight of at least 15 kg. Testing after 1 hour curing.

SOLVENT WELDING CAN-NOT BE USED TO rEWELD UNWELDED ArEAS WHEN S O L V E N T W A S U S E D INITIALLY.

Seam sealer is then applied to the finished areas.


f - THE fIXED sysTEM VapOUR CONTROL LayER & INsULaTION

THE FIxED SYSTEMa lkorPLAN ® F i s the most common system used when ins ta l l i ng rENOLIT roo f ing membranes. It is usually laidon a trapezoidal metal deck.

VAPOUr CONTrOL LAYEr & INSULATION Vapour Control Layer is laid over themetaldeck. It isoverlappedby a minimum of 100 mm and sealed.

The spec i f i ed th ickness o f insulation board is laid in a “break-bonded” style and fixed according to the wind loading calculations and the manufacturers approved fixing system.

At terminat ions, the VCL is taken up and sealed to details and penetrations in accordance with Part L2 of the UK Building Regulations.


f - ROOfINg sHEET

rOOFING SHEETT h e a l k o r P L A N ® r o o f i n g membrane is la id at 90 de-grees to the deck direct ion.

The alkorPLAN® roofing mem-brane has two lines printed along the edge during the manufacturing process. The f irst l ine is the centre line for the fasteners and the second line is the extent of the overlap of the adjacent sheet of alkorPLAN®. This is known as the weld line. There must always be a minimum of 10 mm between the edge of the pressure plate and the edge of the alkorPLAN® roofing membrane.

NOT OK

OK


fasTENERs & alkorpLUs® metalsheet EDgE DETaILs

FASTENErSThe pressure plates are spaced according to the wind loading calculation but not closer than twice the length of one plate. A min imum of 2 fas teners per m² must be respected at a l l t imes. Only approved fasteners shall be used. If indoubt contact our technical department. When insta l l ing the pressure p la tes ensure that they are not over tightened. The pressure plates work in a different way from those used to f ix the insu lat ion board. When instal led correctly they should move when twisted firmly with the thumb and forefinger. A fastener that is over tightened becomes ineffective and places greater strain on the adjacent screws. Over tightened screws must be replaced.


alkorpLUs® metalsheet EDgE DETaILs

ALKOrPLUS® METAL-SHEET EDGE DETAILSAt the perimeter of the roof the alkorPLUS® metal profi les are used to terminate the alkorPLAN® roof ing membrane. They are prefabricated to the required prof i le for each job and are cut and bent on site to fit the edge detail of the roof. The alkorPLUS® metal profiles are f ixed with a waterproof joint before the installation of the main alkorPLAN® roof ing membrane. Unless otherwise advised, the metal profile is fixed using self tapping screws at 250 mm centres with the first fixing 50 mm from the end of the profile. The alkorPLUS® metal profiles are f ixed leaving a minimum 5 mm gap between each profile. The gap is covered with a 50 mm wide Aluband tape. This gives a 50 mm wide unwelded gap between sections which allows a sufficient area of membrane for expansion and contraction movement in the joint.A 200 mm w ide s t rap o f alkorPLAN® is then welded over the joint to form a waterproof edge detail for the termination of the alkorPLAN® field sheet.


bUTT sTRaps T JOINTs & CapILLaRIEs

BUTT STrAPSCare must be taken to ensure that alkorPLAN® membrane is securely welded into the right angle corners of upstands.Ifbuttstrap isspotwelded intoposition and these right angle welds are carried out first, this will ensure that the joint is waterproof. After welding, the joint must be checked but the seam sealer must wait until the field sheet hasbeeninstalled.Itisnotgoodpractise to weld alkorPLAN® roofing membrane over seam sealer.(AxonM1,Page34)

T JOINTS & CAPILLArIESWhere the a lkorPLAN® f ie ld sheet runs across a butt strap a “T” joint will be created. The weld over the capillary should be f i rmly welded us ing the 6 mm brass roller, before the weld between membrane and a l k o r P L U S ® m e t a l s h e e t i s completed.


END JOINTs

END JOINTSEnd joints of subsequent rolls of alkorPLAN® roofing membrane must be cleaned to remove any tape or adhesive used in the rolling of the membrane and then must be overlapped by 250 mm and then welded in the normal way. The end joints across the roof must be staggered to give a minimum of 500 mm between each joint.

E x p o s e d c o r n e r s o f alkorPLAN® roofing membrane field sheet must be rounded. Ensure that the diameter of this rounded effect on the corner is same over the whole roof. This will give the roof a neat appearance.


DIRECTION CHaNgEs & UpsTaNDsDRIp EDgEs

DIrECTION CHANGES & UPSTANDS Where the roof shape changes from a horizontal plane to an angled or vertical plane, a section of a lkorPLUS® metal prof i le must always be used to facilitate this change of direction. The alkorPLAN® roofing membrane is cut to fit the horizontal alkorPLUS® metalsheet plane and welded to it in the normal way. The alkorPLUS® metalsheet follows the change of direction and alkorPLAN® membrane is cut to fit the vertical leg of the alkorPLUS® metalsheet section and welded to it. When a right angled section of alkorPLUS® metalsheet is installed, it must only be fastened to the substrate, in the horizontal plane. (AxonM2Page35;DetailF1,Page36)

The spac ing beween in ter-mediate prof i les is 500 mm. The intermediate prof i le can be substituted by gluing the alkorPLAN® membrane to the roof substrate. The alkorPLUS®

81040

contact glue must be applied on both sides. (2x150g/m²consumption).


CORNERs

DrIP EDGESCompressive foam tape must be used to seal the drip edge to the galvanised profile and substrate to prevent wind ingress. COrNErSCorners are formed by cutting and welding the areas of roofing sheet to the point of the corner and welding a prefabr icated internal or external corner piece over the point where the roofing sheets meet. Care must be taken when install ing corners to ensure that the membrane is welded into the point of the corner. If the corner piece isspot welded into position and the point of the corner is welded first, this wil l ensure that the corner will be waterproof when the rest of the welding has been carried out.


DaMagE & REpaIRs

DAMAGE & rEPAIrSDamage to membrane must be repaired using welded patches. Ensure the area is clean and dry. The patches must be cut to allow a minimum welded width of 50 mm and a 50 mm gap between the damage and the edge of the patch. Hence the smallest patch to repair a pinhole would be 200 mm in diameter.

It is good roofing practise todisguise patches. The customer does not want a new roof with patches in it. For patches in a new roof, cut the required length from a full width roll of alkorPLAN® roofing membrane and weld this piece into position as if it were a roll end. Round the corners in the normal way.


WELDs

WELDSWith the hot air welding gun, the installer must endeavour to form a 50 mm wide weld using the fish tail nozzle. The welding must be continuous and have no air inclusions. Narrow welds will be condemned.

Hot air welding can be used on all areas to be waterproofed. Solvent welding can only be used on the lap joints of new alkorPLAN® roofing material and then only when the conditions areappropriate(seeearlier,undersolventwelding).


a - THE aDHERED sysTEM

THE ADHErED SYSTEMThe alkorPLAN® A system uses alkorPLUS 81068 PU glue to glue the alkorPLAN® fleece backed membrane to the substrate of theroof.It isappliedfromsinglecan or from a number of cans mounted on an applicator trolley.

The amount of glue to be used is specified by the wind load calculat ion carr ied out by a qualified engineer.

When the adhesive is applied in lines, as illustrated, it must be squeegeed across the width of the membrane to create a full bond.


a - THE aDHERED sysTEM

The installation of the alkorPLAN® A sys tem d i f f e rs f rom the alkorPLAN® F, fixed system in one important way. The alkorPLUS® metal profiles are installed, fixed and water-proofed over the installed alkorPLAN® roof sheet.

The junction between alkorPLUS® metalsheet profile and roofing sheet is then waterproofed by a cover strap, welded to both in the approvedmanner.(AxonA3Page56;DetailA3page57)

Corners, vents and pipes are installed using the same methods as for the alkorPLAN® F system.

The alkorPLUS® metal perimeter roof terminations are waterproofed as described in the alkorPLAN® F system but, as detailed above, fixed over the membrane and waterproofed.


THE LOOSE LAID AND BALLASTED SYSTEM

The alkorPLAN® used in this system is specially formulated for use in the extreme environments caused when the membrane is covered and held down using a ballastedrestrainingsystem.Itisglass-fibre reinforced to give extra dimensional stability.

Do NOT attempt to use other types of membrane for th is application.

PIPE PENETrATIONSPenetrations through the roofing sheet such as pipe out lets, supports for air handling units, posts for Mansafe systems, etc. are waterproofed with a patch of alkorPLAN® membrane stretched over the obstruction, and welded to a collar of membrane around the penetration. This is then waterproofed with seam sealer and/or a stainless steel cl ip.(DetailG4,Page65)
