Description
TITEL Anordning Mr infOring av objekt genom tatskikt i byggnadskonstruktioner UPPFINNINGENS TEKNISKA OMRADE Uppfinningen hanfOr sig till en anordning Mr infOring av objekt genom tatskikt i byggnadskonstruktioner sasom vagg, tak eller golv, vilken anordning dr inrattad att sluta sig tatande omkring det infOrda objektet och mot tatskiktet, sasom en byggfolie. TITLE Device Mr infOring of objects through tat layers in building structures TECHNICAL FIELD OF THE INVENTION The invention relates to a device for inserting objects through tat layers in building structures such as a cradle, roof or floor, which device is designed to stop tucking around the inserted object and against the tat layer, such as a building foil.
BAKGRUND OCH RAND TEKNIK En val fungerande ventilation i byggnader ãr en viktig hdlsofaktor for dem som vistas i byggnaden. Det är sdledes av stor betydelse att bostadshus, kontorlokaler, kommersiella byggnader etc. tillhandahalls effektiv ventilation i och for utbyte av fororenad inomhusluft mot renare uteluft. Fororeningar i inomhusluften kan till exempel utgOras av damm, partiklar och odOrer fran byggnadsmaterial, inredningsmaterial, djur och manniskor, eller fran aktiviteter sdsom traning, matlagning, stadning, tvattning, rokning mm. Luftens rorelse i en byggnad innefattar vanligtvis att uteluft tillfors utifran Mr att passera genom byggnadsutrymmena och fOr att darefter lamna byggnaden via en aktiv franluftsventilation. For att detta skall fungera mdste undertryck rdna i byggnaden, och en mOjlighet till lufttillfOrsel finnas exempelvis via vagg- eller Risterventil, sa att cirkulation genom byggnaden alstras. BACKGROUND AND BORDER TECHNOLOGY A choice of functioning ventilation in buildings is an important health factor for those staying in the building. It is therefore of great importance that residential buildings, office premises, commercial buildings, etc. are provided with efficient ventilation in and for the replacement of polluted indoor air with cleaner outdoor air. Pollution in the indoor air can Examples are dust, particles and odors from building materials, interior materials, animals and people, or from activities such as training, cooking, parking, washing, smoking and more. The movement of air in a building usually involves supplying outdoor air from outside Mr to pass through the building spaces and then leaving the building via an active exhaust ventilation. In order for this to work, the minimum negative pressure must be present in the building, and there is an opportunity for air supply, for example via a cradle or grating valve, so that circulation through the building is generated.
Genom att tata byggnadens yttervaggar, tak och golv mot luftlackage undviks inte endast drag utan aven temperaturgradienter i vertikal riktning i byggnadsutrymmet. Om byggnaden är otat finns risk att detta inverkar negativt pd luftfOrdelningen, och otathet/lackage kan ge upphov till oavsiktlig ventilation. Med god lufttdthet och raft dimensionerat till- och franluftsflode erhalls vanligtvis den basta ventilationseffekten. By tilting the building's outer walls, roof and floor against air lacquer, not only drafts but also temperature gradients in the vertical direction in the building space. If the building is unoccupied, there is a risk that this will have a negative effect on the air distribution, and leaks / leakage can give rise to unintentional ventilation. With good air tightness and raft dimensioned supply and exhaust air flow, the best ventilation effect is usually obtained.
En tat byggnadskonstruktion innebar dessutom lagre energifOrbrukning, mindre risk RV fuktkonvention, mindre risk Mr att kall/varm luft ldcker in vid exempelvis fonster, dorrar, golvvinklar, genomforingar, anslutningar etc., och en tat byggnadskonstruktion innebar darmed awn mindre risk fOr ytkondensation eller relativ fuktighet pa insidan av byggnadskonstruktionen. 2 Mot denna bakgrund forses nya byggnader vanligtvis med tatskikt i form av en fukt- och gas-tat plast, vanligtvis betecknad byggfolie, vilken infogas i byggnadens yttervaggar, tak och golv. Det ãr darvid ofrdnkomligt att taskiktet uppvisar ett flertal skarvar, och att nodvandiga oppningar maste goras i tatskiktet for inforing genom taskiktet av rOr, kablar eller andra objekt sasom kopplingsdosor och dylikt. A tat building construction also meant lower energy consumption, less risk RV moisture convention, less risk Mr that cold / hot air covers in at eg windows, doors, floor angles, penetrations, connections, etc., and a tight building construction thus meant awn less risk of surface condensation or relative humidity on the inside of the building construction. 2 Against this background, new buildings are usually provided with tat layers in the form of a moisture- and gas-tight plastic, usually referred to as building foil, which is inserted into the building. exterior walls, ceilings and floors. It is then impossible for the task layer to have one several joints, and that necessary openings must be made in the tat layer for insertion through the tassel layer of tubes, cables or other objects such as junction boxes and the like.
Varje skarv eller Oppning i taskiktet innebar emellertid potentiell risk RV uppkomst av lackage, och skarvar eller oppningar maste darfor tatas manuellt for att 10 undanrOja risken for fukttransport inifran och ut i byggnadskonstruktionen. However, each joint or opening in the roof layer entailed a potential risk of RV leakage, and joints or openings must therefore be taken manually to eliminate the risk of moisture transport inside and out of the building structure.
Skarvar i taskiktet kan taas effektivt med hjalp av nagon 5.1dersbestandig och fOr andamalet godkand byggtejp. En tejp Or dock mindre andamalsenlig da man skall tata omkring ett rOr, en kabel eller annat liknande objekt som skall inforas och 15 strdcka sig genom tatskiktet. Joints in the task layer can be taken efficiently with the help of a 5.1-resistant and for the second approved building tape. A tape Or, however, less andamalsenlig then one should wrap around a pipe, cable or other similar object to be inserted and extend through the wire layer.
FOr det senare andamdlet finns pa marknaden sarskilda rOr-manschetter utformade for att tOta vid genomfOringar. Dessa ror-manschetter ãr antingen fardigformade och tillpassade for objekt av olika storlekar, alternativt forberedda for utskarning av 20 ett hal av lamplig storlek anpassad till det aktuella objektet. For the latter purpose, there are special pipe sleeves on the market designed to seal during penetrations. These rudder sleeves are either prefabricated and adapted for objects of different sizes, or alternatively prepared for cutting a hall of suitable size adapted to the object in question.
Problematiken med i fOrvag stansade rOr-manschetter Or att flera storlekar mdste medforas i arbetet, samt forstas att ingen storlek far ta slut da arbete i sa fall maste avstanna. The problem with rOr cuffs punched in advance is that several sizes must be carried in the work, and it is understood that no size must end as work must in that case have to stop.
Problematiken med rOr-manschetter ddr man vid varje tillfãlle skar ut ett till 25 objektet anpassat hal dr dels att anpassningen Or tidskravande, dels att det Or arbetstekniskt svart att skara ut mindre hal, samt att man vid urskarningen anvander en kniv med risk Mr att rOr-manschetten skadas genom ett felaktigt skar. The problem with rOr cuffs is that on each occasion a hal is cut out that is adapted to the object, partly because the adaptation is time-consuming, partly because it is technically black to cut out a smaller hal, and that at the cut-out uses a knife with risk Mr that the rOr cuff is damaged by an incorrect cut.
I sammanhanget skall noteras att kablar och rOr ofta fOljer utmed taskiktets insida. Nar exempelvis en kabel infors genom tatskiktet sker detta under samtidig bOjning av kabeln for att andra dess riktning. Denna bOjning orsakar en spanning i kabeln, och darmed Oven i tatskiktet. Vid en genomfOring av detta slag genom tatskiktet Or det mycket svart att astadkomma tatning runt kabeln med hjalp av tejp. 3 REDOGORELSE FOR UPPFINNINGEN FOreliggande uppfinning syftar till att undanrOja ovan namnda olagenheter forknippade med befintliga anordningar och metoder for tatning runt kablar, ror eller andra objekt som skall infOras RV att strdcka sig genom ett tatskikt i en 5 byggnadskonstruktion. In this context, it should be noted that cables and pipes often follow along the inside of the task layer. When, for example, a cable is inserted through the tat layer, this happens at the same time bending the cable to change its direction. This bending causes a tension in the cable, and thus in the top layer. When carrying this type through the sealing layer, it is very difficult to seal around the cable with the help of tape. 3 DESCRIPTION OF THE INVENTION The present invention aims to eliminate the above-mentioned malfunctions associated with existing devices and methods for sealing around cables, pipes or other objects to be introduced into the RV to extend through a sealing layer in a building structure.
Syftet uppfylls genom ett ang-tat, elastiskt och sjalvtatande membran som är inrattat for att tdta runt det inforda objektet samt inrattat for att forbindas tatande med tatskiktet. The object is fulfilled by an attached, elastic and self-tapping membrane which is arranged to seal around the inserted object and arranged to be connected tautly to the tapping layer.
Narmare bestamt anvisas genom uppfinnen en anordning inrattad for inforing av objekt genom tatskikt i byggnadskonstruktioner sasom vagg, tak eller golv, vilken anordning innefattar ett membran av ett ang-tatt och elastiskt material med hog tojbarhet utan att deformeras permanent, vilket membran är format med atminstone en expanderbar anvisning for genomfOring av ett objekt under reversibel vidgning av anvisningen genom tojning av membranet. Anordningen utmarks vidare av att membranet pa en sida är palOrt ett adhesiv som utbreder sig sammanhangande, utan avbrott, runtom den aminstone ena anvisningen. More specifically, it is indicated by the invention that a device is provided for introducing objects by tat layers in building structures such as cradles, roofs or floors, which device comprises a membrane of a tight and elastic material with high ductility without being permanently deformed, which membrane is formed with at least an expandable instruction for carrying out an object during reversible widening of the instruction by stretching the membrane. The device is further marked out in that the membrane on one side is palOrt an adhesive which spreads coherently, without interruption, around the aminstone one instruction.
Membranet kan med fOrdel utgOras av en termoplastisk elastomer. Termoplastiska elastomerer eller termoplastiska gummin gar vanligtvis under beteckningen TPE och Mr till gruppen sampolymerer eller bestar av blandningar av polymerer med termoplastiska och elastomeriska egenskaper. Ett av kannetecknen for termoplastiska elastomerer är deras formaga till tojning och atergang till ursprunglig form ndr belastningen upphOr, och de uppvisar ofta fOrmaga till sjalvfOrslutning och sjalvlakning av mindre stickhal och snitt i materialet. Flera lampliga kvaliteter är kommersiellt tillgangliga fran ett flertal tillverkare och med varierande egenskaper. Termoplastiska elastomerer ãr latta att bearbeta och produkter av dessa material kan tillverkas genom formsprutning. The membrane can advantageously be made of a thermoplastic elastomer. Thermoplastic elastomers or thermoplastic rubbers are usually referred to as TPE and Mr in the group of copolymers or consist of mixtures of polymers with thermoplastic and elastomeric properties. One of the hallmarks of thermoplastic elastomers is their ability to stretch and return to their original shape when the load ceases, and they often exhibit the ability to self-seal and self-level of smaller punctures and cuts in the material. Several lamp qualities are commercially available from several manufacturers and with varying properties. Thermoplastic elastomers are easy to process and products from these materials can be manufactured by injection molding.
Bland lampliga termoplastiska plaster kan naninas en termoplastisk polyuretanplast (TPU), och darvid sarskilt en termoplastisk polyuretanplast av det slag som vid uppvarmning stravar att aterga till sin tidigare form. Sadana sa kallade minnesplaster, eller Shape Memory Plastics (SMP), är kommersiellt tillgangliga, till exempel fran bolaget Bayer MaterialScience inom Bayer AGkoncernen. Ett membran tillverkat av sadan minnesplast kan temporart omformas for att vid uppvarmning till en viss temperatur atergâ till sin ursprungliga form. Among suitable thermoplastic plastics, a thermoplastic polyurethane plastic (TPU) can be naninated, and in particular a thermoplastic polyurethane plastic of the type which, when heated, tends to regenerate to its previous shape. Sadana sa so-called memory plastics, or Shape Memory Plastics (SMP), are commercially available, for example from the company Bayer MaterialScience within the Bayer AG Group. A membrane made of such memory plastic can be temporarily reshaped so that when heated to a certain temperature it returns to its original shape.
Minnesfunktionen och egenskapen att vid uppvarmning atergá till tidigare form utnyttjas genom att uppfinningens membran varms till den temperatur som 4 initierar den vidgade genomfOringens sammandragning runt ett dessfOrinnan infOrt objekt. The memory function and the property of returning to an earlier form when heated are used by heating the membrane of the invention to the temperature which 4 initiates the contraction of the widened bushing around a previously inserted object.
Membranet kan alternativt vara tillverkat av naturgummi eller syntetgummi, sasom EPDM-gummi eller butyl-gummi. The membrane may alternatively be made of natural rubber or synthetic rubber, such as EPDM rubber or butyl rubber.
FOr uppfinningens membran valjs fOretrddesvis en mjuk kvalitet med hog tojbarhet utan att en kvarsta.ende deformation intrader hos materialet, vilket darfOr vasentligen atergar till ursprunglig form nar tojningsbelastningen upphor. Med uttrycket "hog tOjbarhet" skall i detta sammanhang fOrstas en fOrmaga till reversibel utvidgning av en anvisning fOr bildande av en oppning vars stOrsta storlek uppgar till atminstone 3-4 ganger storleken hos oppningen i dess tatande form runt ett i Oppningen infOrt objekt. Detta kan belysas med fOljande exempel: vid tatning runt ett objekt med diametern 20 mm skall membranets tOjbarhet fOretradesvis medge att oppningen genom membranet for inforing av objektet kan vidgas till storleksordningen 60-80 mm, utan att en bestaende deformation intrdder hos membranet. For the membrane of the invention, a soft quality with high ductility is preferably selected without a residual deformation entering the material, which therefore essentially returns to its original shape when the strain load ceases. In this context, the term "high extensibility" is to be understood as meaning a capacity for reversible extension of an instruction for the formation of an opening whose largest size is to at least 3-4 times the size of the opening in its gripping shape around an object inserted in the opening. This can be illustrated by the following example: when sealing around an object with a diameter of 20 mm, the extensibility of the membrane should preferably allow the opening through the membrane for insertion of the object to be widened to the order of 60-80 mm, without an existing deformation occurring in membrane.
Pa detta satt utnyttjas i uppfinningen minnesfunktionen hos ett material som efter tojning stravar att aterta sin ursprungliga form, och som i denna stravan astadkommer en tatning runt ett objekt som är infOrt genom en tillfalligt vidgad Oppning genom membranet. En exakt mattpassning av anvisningen till objektets storlek ãr inte heller nodvandig for att membranet skall tata runt objektet, emedan den ursprungliga anvisningen alltid är mindre an objektets storlek/diameter och membranet darfOr utOvar en klamkraft runtom objektet. In this way, the invention utilizes the memory function of a material which, after stretching, strives to regain its original shape, and which in this strain provides a seal around an object which is inserted through a temporarily widened opening through the membrane. An exact carpet fit of the instruction to the object size is also not necessary for the membrane to wrap around the object, since the original instruction is always smaller than the size / diameter of the object and the membrane therefore exerts a clamping force around the object.
Vidare ãr namnda anvisning fOretradesvis formad i ett avgransat delomrade av membranet som uppvisar en forsta tjocklek, medan omgivande omrade av membranet uppvisar en andra och stOrre tjocklek. Det omgivande omrade av membranet kan vara 2-20 ganger tjockare an delomradet van i anvisningen ãr utfOrd och placerad. Furthermore, said instruction is preferably formed in a defined sub-area of the membrane which has a first thickness, while surrounding areas of the membrane has a second and larger thickness. The surrounding area of the membrane can be 2-20 times thicker than the subarea used in the instructions is made and placed.
I ett fortjanstfullt utforande ãr anvisningen formad innanfor en i materialet formad ring, som hOjer sig Over ytan hos det omgivande membranet. In a meritorious embodiment, the instruction is formed within a ring formed in the material, which rises above the surface of the surrounding membrane.
Anvisningen dr med fOrdel formad i ett materialskikt som bildar talc i en Oppning genom membranet, vilken Oppning har formen av en stympad kon som vidgar sig mot en mynning i membranets undersida. The instruction is advantageously formed in a layer of material which forms talc in an opening through the membrane, which opening has the shape of a truncated cone which widens towards an orifice in the underside of the membrane.
Anvisningen ãr foretradesvis utford som i kryss lagda, genomgaende eller partiellt genomga.ende, snitt i membranet, varvid vart och ett av kryssets fyra ben avslutas med ett tvdrstallt, genomgaende eller partiellt genomgaende, snitt. UtfOrandet med det tvarstallda snittet Okar membranets fOrmaga att motstá sprickbildning och forhindrar att anvisningen propagerar vid kraftig vidgning av anvisningen. The instruction is preferably a challenge as a cross-section, continuous or partially continuous, incision in the membrane, each of the four legs of the cross ending with a transverse, continuous or partially continuous, incision. Execution with the transverse section increases the ability of the membrane to resist cracking and prevents the instruction from propagating when the instruction is greatly expanded.
I ett fOredraget utforande ãr membranet utfort med en snedstalld periferi med en runtom gd.ende, radiellt utskjutande flans, som pd sin undersida uppbar ett 5 adhesivskikt. In a preferred embodiment, the membrane is formed with an inclined periphery with an all-round, radially projecting flange, which on its underside carried an adhesive layer.
Membranet kan alternativt vara fOrenat med en stabiliserande ram. Denna ram kan vara utford av ett polymermaterial, och ram och membran kan alternativt vara forbundna genom ett samgjutningsfOrfarande. The membrane may alternatively be contaminated with a stabilizing frame. This frame can be challenged by a polymeric material, and frame and membrane may alternatively be connected by a co-casting process.
Membranet kan alternativt uppvisa flera anvisningar for genomfOring av objekt, och kan till exempel uppvisa dtminstone tre cirkuldra delomrdden med genomforingsanvisningar for genomfOring av objekt med sinsemellan lika eller olika diametrar, och kan i detta utforande tillhandahdlla en anordning som är anpassad for genomfOring av rEir, ledning och kabel i olika dimensioner. The membrane may alternatively have several instructions for carrying out objects, and may, for example, have at least three circular subareas with bushing instructions for bushing objects of equal or different diameters, and may in this embodiment provide a device adapted for bushing, wire and cable in different dimensions.

BRIEF DESCRIPTION OF DRAWINGS An embodiment of the invention is described in more detail below with reference to the accompanying schematic drawings. Of the drawings show Figure 1 is a plan view showing the top or outside of a device according to the invention, and Figure 2 is a cross-section through the device of Figure 1 along the line II-II in Figure 1.
DETALJERAD BESKRIVNING AV UTFORINGSEXEMPLET Med hanvisning till Figur 1 och Figur 2 visas en anordning inrattad for inforing av objekt genom tatskikt i byggnadskonstruktioner sdsom vagg, tak eller golv. Anordningen innefattar ett skivformigt element 1 bestd.ende av ett angtatt och elastiskt material utgOrande ett membran 2, i vilket är format en anvisning 3 RV genomfOring av ett objekt, sdsom ett slang- eller rorformat objekt. Membranet 2 kan sdsom i det visade utforingsexemplet ha cirkuldr eller cirkuldrcylindrisk form, men kan alternativt ha annan utformning, sasom oval eller flerhOrnig form. 6 Anvisningen 3 ãr i fOredraget utfOrande utfOrd som ett kryss hos vilket vart och ett av kryssets ben avslutas genom en tvarstalld markering bildande ett rivstopp vid utvidgning av anvisningen i samband med genomforing av ett objekt. Anvisningen 3 kan vara utfOrd i form av ett genomga.ende snitt eller spar, eller i form av ett endast partiellt genomga.ende snitt eller spar och avsedd att brista vid vidgning av snittet/sparet i och for genomforing av det aktuella objektet. DETAILED DESCRIPTION OF THE EMBODIMENT With reference to Figure 1 and Figure 2, a device is shown provided for inserting objects through tat layers in building structures such as cradles, roofs or floors. The device comprises a disc-shaped element 1 consisting of a tight and elastic material constituting a membrane 2, in which an instruction 3 is formed for carrying out an object, such as a hose or tube-shaped object. Membrane 2 can as in the exemplary embodiment shown have a circular or circular-cylindrical shape, but may alternatively have a different design, such as an oval or polygonal shape. 6 In the lecture, the instruction 3 is made as a cross in which each of the legs of the cross ends by a transverse marking forming a tear stop when extending the instruction in connection with the implementation of an object. The instruction 3 can be made in the form of a continuous cut or cut, or in the form of a mere partially continuous incision or groove and intended to rupture when widening the incision / groove in and for carrying through the object in question.
Anvisningen 3 är formad i ett omrade 4 som hojer sig over ytan av det omgivande membranet, pa membranets ovansida. Sâ som sarskilt framgar av Figur 2 har det upphOjda delomradet 4 mindre godstjocklek an ovrig del av membranet utanfOr omradet 4. Omradet 4 bildar tak Over en oppning 5 som likt formen hos en stympad kon Oppnar sig koniskt vidgande i den motsta.ende sidan eller undersidan av membranet 2. Den invandigt koniska formen hos oppningen 5 sakerstaller en forhojd tatningsformaga runt ett objekt som infors for att stracka sig genom membranet, via Oppningen 5. The guide 3 is formed in an area 4 which rises above the surface of the surrounding membrane, on the upper side of the membrane. As can be seen in particular from Figure 2, the raised subarea 4 has a smaller wall thickness than the rest of the membrane outside the area 4. The area 4 forms a roof Over an opening 5 which, like the shape of a truncated cone, opens conically widening in the opposite side or underside of the membrane 2. The internally conical shape of the opening 5 has a raised sealing shape around an object which is inserted to extend through the membrane, via the opening 5.
Det upphojda omradet 4 ansluter till omgivande del av membranet via ett overgangsomrkle 6 av tunnare gods. Overgangsomradet 6 tillfor en okad flexibilitet som vid behov tillater snedstallning och vinkling av det upphOjda omradet 4 i forhallande till omgivande del av membranet. Denna funktion Okar anordningens formaga att tata runt ett objekt som stracker sig i sned vinkel genom anordingen och tatskiktet. The raised area 4 connects to the surrounding part of the membrane via a transition area 6 of thinner goods. The transition area 6 provides an increased flexibility which, if necessary, allows tilting and angling of the raised area 4 in relation to the surrounding part of the membrane. This function increases the device's ability to move around an object that extends at an oblique angle through the device and the tat layer.
Pa membranets undersida är ett adhesivskikt 7 pafort. Adhesivskiktet 7 kan utbreda sig over hela ytan av membranet, men stracker sig kminstone runtom utmed membranets periferi sâ att genomforingen i form av oppningen 5 och anvisningen 3 fullstandigt omges av adhesivskiktet. RV att skydda adhesivskiktet under lagring och transport ãr lampligen en skyddsfilm, pa i sig kant salt, applicerad Over adhesivet 7 tills anordningen monteras mot ett tatskikt med hjalp av namnda adhesivskikt 7. On the underside of the membrane an adhesive layer 7 is applied. The adhesive layer 7 can spread over the entire surface of the membrane, but extends at least around the periphery of the membrane so that the bushing in the form of the opening 5 and the guide 3 is completely surrounded by the adhesive layer. RV to protect the adhesive layer during storage and transport, a protective film, on itself edge salt, is suitably applied over the adhesive 7 until the device is mounted against a sealing layer by means of said adhesive layer 7.
Adhesivskiktet 7 kan alternativt, eller i tillagg, vara pafort pa undersidan av en flans 8 som utskjuter radiellt fran membranet och Riper runt membranets periferi. The adhesive layer 7 may alternatively, or in addition, be provided on the underside of a flange 8 which projects radially from the membrane and scratches around the periphery of the membrane.
Namnda flans 8 kan vara integrerat formad i membranet, men kan alternativt och foredraget utgOras av en till membranet fogad separat flansring 9. Flansringen 9 är fastad mot en fasad utsida 10 av membranet och strdcker sig ett stycke radiellt ink Over membranets ovansida for att ocksa vara fastad till ovansidan. Flansringen 9 kan utgoras av en fOr andamalet utformad tejp som klistras mot membranet. Said flange 8 may be integrally formed in the membrane, but may alternatively and preferably be formed by a separate flange ring 9 attached to the membrane. The flange ring 9 is fixed to a bevelled outside 10 of the membrane and extends a distance radially above the top of the membrane to also be attached to the top. The flange ring 9 can be formed of a pre-molded tape which is glued to the membrane.
Flansringen 9 kan alternativt vara sammanfogad med membranet genom ett 7 samgjutningsfOrfarande, och kan i detta utfOrande ha funktionen av en stabiliserande ram besta.ende av ett material som kan samgjutas med membranet. The flange ring 9 can alternatively be joined to the membrane by a 7 co-casting method, and in this embodiment may have the function of a stabilizing frame consisting of a material which can be co-cast with the membrane.
