Rhepanol® fk – advantages

Tried and tested long-term reliability, over 50 years of experience with polyisobutylene The oldest synthetic roofing membranemade in Germany With a unique self-sealing edge for reliableand fast sealing of seams Fleece backing with extremely high tensilestrength Made of polyisobutylene (PIB), thereforecompatible with bitumenOne roofing membrane for all applicationmethodsThe only roofing membrane to be appliedwith the Gripfix systemResistant to UV-radiationFlexible at temperatures as low as – 60 °C Free of plasticizersApplication without open flame No need for surface protection Comprehensive warranty on materials Ideal for refurbishment

The self-sealing edge system

The pre-fabricated self-sealing edge system isdifferent from conventional adhesive bonding.Sealing of the seams is carried out by firmly joining homogenous materials. Immediatelyafter the self-sealing edge has been pressed tothe connecting membrane the seam is alreadywaterproof. Owing to the integrated self-sealing edge, seams can be sealed withoutopen flame, hot air, solvent welding or addi-tional adhesives, making application more efficient and almost independent of weatherconditions.

Safety and functional efficiency,supporting construction

Safety and functional efficiency

With mechanical fastening the roof sealing is separated from the lower layers and com-ponents across the complete area. Movementsof these layers and components can thereforenot pass on stresses to the sealing, which issignificant for the prevention of damage, especially on lightweight roofs. The roofingmembrane Rhepanol fk is rolled onto mechani-cally fastened Gripfix strips, providing optimalwind load distribution and securing the membrane permanently to the roof.

The membrane seams run perpendicular to theGripfix strips and thus are not affected by winduplift forces.

The integrated highly tear-resistant syntheticfleece of Rhepanol fk allows diffusion of anyretained moisture.

The supporting deck structure has to meetthe requirements with regard to load-bearingcapacity, deflection, anchorage and drainage.

Substrates for application must be free of open cracks, concrete, rough and sharpprojections.

Joints have to be formed according to constructional requirements, as their widthor movement may impede the functionalefficiency of the roof seal.

Clean, dry and even roof surfaces.

If Rhepanol fk is directly laid on concretedecks/screed allow the concrete/screed to setfor at least 28 days.

The effect of air escaping from the buildingat the roof perimeter and at roof penetra-tions must be prevented. Therefore theseareas have to be made airtight. In the caseof profiled steel decking, seal around all openings and perimeters.

For compatibility reasons, timber board cladding, chipboards and similar may be treated only with salt-based wood preserva-tives. Oil or solvent based impregnationagents must not be used.

National standards and regulations must beobserved.

The mechanicalfastening ofRhepanol fk withGripfix systemensures secure,fast and effectivelaying.

Rhepanol fk is compatible with bitumen andcan be applied without additional separationlayers directly on to old bituminous sheets. The integrated synthetic fleece protects themembrane against movement originatingfrom the substrate.

Application instructions

Supporting construction


Vapour control layer,thermal insulation layer

For non air-conditioned rooms (e.g. livingrooms and offices or similar rooms withoutsuspended ceiling): vapour barrier fk (ethylene).

In the case of lightweight concrete support-ing decks with correctly calculated thermalinsulation, you may leave out a vapour control layer, if the room temperature staysbelow 20 °C and the relative air humidity inside the room will not exceed 65 %. In case of doubt, we recommend a calculationof the building physics in order to identify thediffusion characteristics of the roof build-up. With lightweight steel deckings, we alsorecommend in principle the installation of aseparate vapour control layer, which shouldbe formed as an air barrier according to theprovisions of the Thermal InsulationRegulation.The vapour barrier fk is applied with a seamoverlap of 10 cm, with the seams being sealed with connection or seam tape. Thevapour barrier must be taken up and flashedat connections and cappings; at roof pene-trations it must be flashed.

For rooms with high air condition loads:In case of air-conditioned rooms and roomswith high air condition loads, as well as high pressure rooms, there should be nomechanical fastening through the vapour barrier. In these cases please consult ourexperts to identify the right layer build-upand application method.


Vapour control layer

In the case of non-ventilated roofs, we rec-ommend the following vapour control layers:

Thermal insulation layer

When designing the thermal insulation layer onsteel profile supporting decks, attention mustbe given to load bearing capacity.

As materials for thermal insulation layers werecommend:

For roof slopes up to 20°: large-sized insulation boards made of quality assuredrigid polyurethene or rigid polystyrene foamwith rebated edge, size 1.20 x 1.20 m or1.20 x 1.00 m. On top of the insulation boards, for fire protection reasons, the application of a fireprotection layer – a specially coated wovenglass cloth – will be necessary.

Compressed mineral fibre insulation mayalso be used.

Folding insulation boards or rigid poly-styrene foam boards with backing. For fire protection reasons, bituminous sheetswith an integrated glass fleece or fabric ≥ 60 g/m2 may be necessary as a lining. Use linings with a PE foil or fleece facing.

Large-sized non-flammable mineral fibreboards. Because of better suitability formechanical fastening we recommendboards with a greater resistance to pointloads (min. 500 N at 5 mm deformation)and a higher compression strength (com-pressive strain at 10 % compression setmin. 0.06 N/mm2).

Small-sized insulation boards can be used,provided they can be properly fastened.


Rhepanol® fkmechanically fastened with Gripfix system Application techniques12


Themal insulation layer, Rhepanol® fk, mechanically fastened with Gripfix system

Insulation boards or board sections that are notsufficiently fixed with Gripfix must be securedin a stable position with additional fasteners (at least 2 fasteners/m2) prior to applying theroofing membrane.

Insulation materials that are not dimension-ally stable and which buckle or bulge mustnot be installed. Generally insulation boardsmust be laid brick-bond pattern.

Rhepanol® fk, mechanically fastened withGripfix system

The Gripfix strips are placed according to the wind uplift calculation and mechanicallyfastened. The Gripfix strip spacing is variabledepending on the wind load requirements. The roofing membrane Rhepanol fk is thenloosely laid with a seam overlap of 5°perpendicular to the Gripfix strips. The grip is achieved by thoroughly rolling the roofingmembrane Rhepanol fk to the Gripfix strip. The membrane width is always 1.05 m.Depending on the substrate a variety of different fasteners may be used.

Rhepanol® fkmechanically fastened with Gripfix system Application techniques

� With the Gripfix system you must use only the specially marked Rhepanol fk roofingmembranes.

� The max. wind force (including safety factor 1.5) per m Gripfix strip is 1.5 kN.

The design load is max. 0.5 kN/fastener.Instructions of the fastener manufacturer mustbe observed.

At building heights over 20 m and in specialcases (e.g. airplane hangars, buildings near thecoast, extreme exposure) each characteristic ofthe project location and special conditions mustbe taken into account.

On request, computer-based project specific cal-culations of the necessary amount of fastenersand Gripfix strip spacing are carried out, whichmay result in lesser amounts of fasteners thanindicated in the table, provided the building hasa favourable geometry.

Rhepanol fk can be mechanically fastened onroofs with any slope.

At slopes exceeding 20°, application should beagreed with our experts.

On profiled steel deckings and timber boardcladding the Gripfix strips must be arranged per-pendicularly to the corrugations or boards toachieve the most regular wind load distributionpossible into the supporting deck.

At all flashings and cappings, roof lights etc. the build-up must be specially secured by circumferential rows of fasteners or Gripfix strips(min. 4 fasteners/m).

Note:

� Max. spacing of Gripfix strips see table above.

� Fastening spacing on the Gripfix strip min. 15 cm, max. 60 cm.

� Fastener spacing on the same corrugation atprofiled steel deckings must not be less than20 cm.

� Use only fasteners with washers of max. 5 cmwidth.

Flashings and cappings

All flashings and cappings are carried out withRhepanol fk flashing strips.

If the connecting membrane is bonded, then atflashing heights over 20 cm a full-size adhesivebond is necessary. Valley areas are left unbondedat a width of 20 cm to allow movement com-pensation. If the connecting membrane ismechanically fastened with Gripfix strips the fol-lowing spacing must be observed (s. also sketch):– Distance of the first Gripfix strip from the

internal corner of the parapet max. 10 cm– Spacing between the Gripfix strips or distance

between Gripfix strip and upper capping max.50 cm.

With wall flashings, the upper edge of theRhepanol fk roofing membrane is pressed to the substrate with rigid wall connection profilessuch as “Classic” and additionally secured with sealant A or S. The two-part FDT roof edge trims ensure flexible, yet windproof capping ofthe roof perimeter. Forming of flashings and cappings is identical for all application methods.You will find details on this topic in the drawings“Technical details”.

Additional requirements for roof refurbishment:

� In the case of uneven substrates, protectionlayers are necessary. Rigid polystyrene foaminsulation boards or sheets can be recom-mended.

� The strength of the supporting deck is crucial for the anchoring of the fasteningelements. If there is doubt about thestrength, e.g. of old pumice stone or lightweight concrete panels, pullout testswill be necessary to define the amount offasteners depending on the object.

Rhepanol® fkloosely laid with ballast Application techniques


Because of loose laying, the roof covering isseparated from the other layers of the build-upacross the complete area. Movements andcracks in the supporting construction are nottransferred into the roof covering.

The ballast ensures the membrane remains secure against wind uplift forces.

Rhepanol fk is compatible with bitumen and canbe applied without additional separation layersdirectly on old bituminous sheets.

The integrated, highly tear-resistant syntheticfleece of Rhepanol fk allows diffusion, ensuring reliable vapour pressure compensation.Furthermore the fleece backing provides protection against stresses originating from the substrate.



� The supporting deck structure has to meet the requirements with regard to load-bearingcapacity, deflection, anchorage and drainage.

� Clean, dry and even roof surfaces.

� If Rhepanol fk is directly laid on concretedecks/screed allow the concrete/screed to set for at least 28 days.

� Substrates for application must be free ofopen cracks, rough concrete, sharp edges and stones.

� Joints have to be formed according to constructional requirements, as their width or movement may impede the functional efficiency of the roof sealing.

Safety and functional efficiency,supporting construction,vapour control layer

� The roof slope should not exceed 3° to preventthe ballast slipping off.

� An intrusion of air underneath the roof covering at the roof perimeter and at roofpenetrations must be prevented. Thereforethese areas have to be made windtight.

� For compatibility reasons, timber board clad-ding, chipboards and similar may be treatedonly with salt-based wood preservatives. Oil or solvent based impregnation agents must not be used.

� National standards and regulations must beobserved.


In the case of non-ventilated roofs, we recommend the following vapour control layers:

� For non air-conditioned rooms (e.g. living rooms and offices or similar rooms withoutsuspended ceiling): vapour barrier fk (poly-ethylene) with µ x s = 120 m.

In the case of lightweight concrete supportingdecks with correctly calculated thermal insulation,you may leave out a vapour control layer, if theroom temperature stays below 20 °C and therelative air humidity inside the room will notexceed 65 %.

The vapour barrier fk can be laid with differentoverlap: either 10 cm if sealing the seams withconnection or seam tape, or 20 cm loose overlap(without seam connection in the area). Preconditions:– seamless solid deck and – dimensionally stable insulation material,

µ larger than 40, e.g. polystyrene, – standard room air conditions.

30


Rhepanol® fkloosely laid with ballastApplication techniques 31

Thermal insulation layer,Rhepanol® fk, loosely laid,ballast

� For rooms with high air condition loads (e.g.swimming pools, air-conditioned rooms):– aluminium compound foils,– vapour control membrane with metal tape

reinforcement, e.g. AL + V 60 S 4.



You must bear in mind tread-fastness whendesigning the thermal insulation layer on steelprofile supporting decks. Quality assured rigidpolystyrene foam boards with rebated edgeand a length of max. 1.25 m are especially suitable materials for thermal insulation layers.

With roof areas for walking on, insulationmaterials with higher compression strength, e.g. rigid polystyrene foam, must be used inaccordance with the expected loads.

Insulation materials that are not dimensionallystable and which buckle or bulge must not beinstalled.

The insulation elements must be laid with pressed joints in bond.


Rhepanol fk, loosely laid

Rhepanol fk roofing membrane is loosely laidwith a seam overlap of 5 cm. The membraneseams are quickly sealed with the prefabricatedself-sealing edge almost independent fromweather conditions. At all flashings and cap-pings, built-in details etc. you will need linearperimeter fixing with at least 4 fastening elements/m.

Ballast

Immediately apply ballast on loosely laid roofing membranes to secure its positionagainst wind uplift.

Suitable materials are:

� bulk gravel layers, min. 5 cm thick, washednatural uncrushed stones, fraction 16/32.

� paving slabs in a fine gravel bed on a protection layer.

If appropriate gravel is not available or the gravel is applied pneumatically, then, as underpaving slabs, you will need an additional pro-tection layer (e.g. synthetic fleece or protectionsheet TS fk). Under screed you will have to apply the protection sheet TS fk.

PE layers and coarse rubber protective sheetsmust have an underlying synthetic fleece layer.

For ballast, the provisions of national wind loadstandards must be observed.

At building heights over 20 m and for roofswith high wind exposure (e.g. tower-style,detached buildings, airplane hangars and buildings near the coast) it is necessary to define appropriate object-related measures for membrane position stability.

� Thoroughly sweep the roof area. Removeany blisters, projections and coarse rough-ness.

� On rough substrates (such as pressed gravel),a protection layer is necessary. We recom-mend polystyrene insulation boards, whichprovide additional insulation at the sametime.

� Temporary storage of gravel must not exceedthe maximum load of the supporting deck.

� Soiled gravel must be cleaned (e.g. by sieving). Otherwise, appropriate protectionlayers such as synthetic fleece 300 g/m2

must be applied.

Safety and functional efficiency,supporting structure,vapour control layer


Bonding Rhepanol fk in stripes ensures maximumpossible mobility of the roofing membrane. Theintegrated, highly tear-resistant synthetic fleeceof Rhepanol fk allows diffusion, thus ensuringreliable vapour pressure compensation and secure bonding to the substrate. Rhepanol fk iscompatible with bitumen and can be bondedwithout additional separation layers, directly toold bituminous sheets. The integrated syntheticfleece protects the membrane against stressesoriginating from the substrate.



� The supporting deck structure has to meet the technical requirements, especially for load-bearing capacity, deflection, anchorage anddrainage.

� Substrates for application must be free of opencracks, rough concrete and sharp projections.

� Joints have to be formed according to constructional requirements, as their width or movement may impede the functional efficiency of the roof sealing.

� An intrusion of air underneath the roof covering at the roof perimeter and at roofpenetrations must be prevented. Thereforethese areas have to be made windtight.

� Clean, dry and even roof surfaces.

� If Rhepanol fk is directly laid on concretedecks/screed allow the concrete/screed to set for at least 28 days.

� The necessity for pre-coating to provide reliable adhesion and dust bonding dependson the substrate conditions.

– Lightweight concrete panels must always be pre-coated, except when using Rhepanoladhesive 90.

� – It is not necessary to pre-coat coated profiledsteel deckings, except when welding on bituminous sheets (only as bonding agent).

� – National standards and regulations must beobserved.


As vapour control layers, in the case of non-ventilated roofs, we recommend:

� For non air-conditioned rooms (e.g. livingrooms and offices or similar rooms withoutsuspended ceiling): Vapour control membrane.In the case of lightweight concrete supportingdecks with correctly calculated thermal insula-tion, you may leave out a vapour control layer,if the room temperature stays below 20 °Cund the relative air humidity inside the roomwill not exceed 65 %.

� For rooms with high air condition loads (e.g. swimming pools, air-conditioned rooms):Vapour control membrane with metal tape,glass fleece or woven glass cloth reinforce-ment.

In case of doubt, we recommend a calculation of the building physics in order to identify thediffusion characteristics of the roof build-up.


Rhepanol® fkbonded fixing Application techniques

Vapour control layer,thermal insulation layer

With lightweight steel deckings, we also recom-mend in principle the installation of a separatevapour control layer, which should be formed asan air barrier according to the provisions of theThermal Insulation Regulation.

� The vapour barrier must be taken up and flashed at connections and cappings, at roofpenetrations it must be flashed.


Note:

For bonding the insulation layer with adhesive U,use vapour control membranes without PE backing or talcum coating.


The thermal insulation layer is to be designed inaccordance with the thermal protection require-ments.As materials for thermal insulation layers werecommend:

� Folding insulation boards or rigid polystyrenefoam boards with backing. For fire protection reasons, bituminous sheetswith an integrated glass fleece or fabric ≥ 60 g/m2 may be necessary as a lining.

� Mineral fibre boards or sheetsWith bonded application using mineral fibreinsulation material, the type of insulationmaterial and the adhesive/amount of ad-hesive needed is to be defined depending on the object.

As a lining, use bituminous sheets without PEbacking.

Generally insulation boards must be laid brick-bond pattern. Insulation materials that are not dimensionally stable and which buckle orbulge, or insulation elements with insufficientlining stability must not be installed.

Bonding of the thermal insulation layer is preferably done with adhesive U, a one-com-ponent polyurethane adhesive.

For roof slopes exceeding 7°, additional sup-porting measures are necessary to prevent thematerials slipping off while the adhesive iscuring.

For further information on the adhesive and itsapplication see data sheet adhesive U.

Rhepanol® fkbonded with Rhepanol-Adhesive 90

Rhepanol fk bonded with Rhepanol-Adhesive 90

With the Rhepanol-Adhesive 90 specially designed for Rhepanol fk, the roofing mem-brane is securely bonded to the substrate. The adhesive is applied in stripes with at least 8 stripes/m.

Adhesive consumption depends on the placeand height of the building and on the bondingsubstrate.

With building heights over 20 m and in thecase of roofs with high wind exposure (e.g.tower-style, detached buildings, airplane hangars and buildings near the coast), it isnecessary to define the amount of adhesiveneeded or appropriate object-related measuresfor membrane position stability.

For roof slopes exceeding 15°, additionalmechanical fastening may be necessary to prevent the roofing membrane slipping offwhile the adhesive is curing. At slopes exceed-ing 20°, application should be agreed with our experts. For information on the adhesive,its application and processing see data sheetRhepanol-Adhesive 90 (page 63).

Rhepanol® fkbonded fixing Application techniques

Linear perimeter fixing,flashings and cappings,roof refurbishment

Linear perimeter fixing

A linear perimeter fixing at flashings and cappings is necessary with supporting decksmade of galvanized profiled steel.

� In general, with bonded roof build-ups withmineral fibre insulation materials, independ-ent from the supporting deck.

The perimeter fixing of the roof build-up, including the roofing membrane, is achieved in each instance with at least 4 fixings/m inline.


All flashings and cappings are carried out withRhepanol fk flashing strips. With flashing heightsof over 20 cm, full-size adhesive bonding of thecovering at the upstand is necessary. Valley areasare left unbonded at a width of 20 cm to allowmovement compensation. The upper edge of the Rhepanol fk roofing membrane is pressed tothe substrate with rigid wall connection profilessuch as “Classic” and additionally secured withsealant A or S. The two-part FDT roof edge trims ensure flexible, yet windproof capping ofthe roof perimeter. Forming of flashings and cappings is identical for all application methods.For drawing example see “Technical details”.


� Before overlaying with Rhepanol fk the adhesion between the old roofing layers,as well as to the supporting deck must becompletely secure. Otherwise mechanicalfastening will be necessary.

� With old roofs bonded with cold bituminousadhesive a mechanical fastening of the oldroof is obligatory due to the plastic dimen-sional dynamics of the cold bituminous adhesive.

� The substrate must be suitable for bonding,free from chippings and thoroughly cleaned.
