Oblasť technikyTechnical field
Vynález sa týka na strane priestoru usporiadanej parotesnej zábrany využiteľnej na tepelnú izoláciu budov, najmä na tepelnú izoláciu novostavieb a na sanáciu starých budov.The invention relates to a space-tight vapor barrier for use in the thermal insulation of buildings, in particular for the thermal insulation of new buildings and for the renovation of old buildings.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Na zníženie vzniku kysličníka uhličitého pri vykurovaní budov sa uskutočňujú pri stavbe nových budov a pri sanácii starých stavieb opatrenia na tepelnú izoláciu. Pre stavebníka z tohto hľadiska vedená ekonomická rozvaha prihliada aj k stavebným nákladom. Pritom je navyše podstatným faktorom vonkajší vzhľad budov, ktorý predstavuje obmedzenie skutočne možného uskutočnenia. Tak sa napríklad na budovách s viditeľnou priehradovou konštrukciou môžu uskutočňovať tepelné izolácie len vnútornými izolačnými vrstvami. Únosné zaťaženie dreva priehradovej konštrukcie vlhkosťou sa musí vzhľadom na možnú difúziu pár najmä v zimných podmienkach zaisťovať vnútornou parotesnou zábranou. Naopak musí mať v letných mesiacoch škárami medzi drevenými stojačkami a výplňami vnikajúca dažďová voda možnosť vyschýnať i smerom do vnútra, aby sa i pri zlepšenej tepelnej izolácii zaistila dlhá životnosť dreva použitého na priehradovú konštrukciu.In order to reduce the production of carbon dioxide in the heating of buildings, thermal insulation measures are being carried out for the construction of new buildings and for the renovation of old buildings. For the builder, the economic balance sheet also takes into account construction costs. In addition, the external appearance of the buildings is an essential factor, which constitutes a restriction on the actual design. Thus, for example, on buildings with a visible lattice structure, thermal insulation can only be carried out with inner insulation layers. Due to the possible vapor diffusion, the bearing moisture load of the lattice timber structure must be ensured, especially in winter conditions, by an internal vapor barrier. On the other hand, in the summer months, the penetrating rain water must be allowed to dry out through the joints between the wooden uprights and the fillings, even in the case of improved thermal insulation, to ensure the long life of the timber used for the truss construction.
Podobné ťažkosti sa vyskytujú pri dodatočnej úplnej medzikrokvovej izolácii pri strmých strechách s parotesným predkrytím (napríklad strešnou lepenkou na drevenom debnení). Zisťovanie inštitútu fyziky stavieb vo Fraunhofe preukázalo, že pri vnútorne osadených parotesných zábranách s difúznym odporom vodných pár /hodnotoud/, ktorý je menší ako difúzne ekvivalentná 10 m hrúbka vzduchovej vrstvy, najmä pri strechách smerujúcich k severu, nie je vysušenie dreveného debnenia v lete dostačujúce na to, aby sa dosiahla vlhkosť dreva nevzbudzujúca pochybnosti. Tak už nemôže vnútri upravená parotesná zábrana odvádzať napríklad konvexiou vyvolaný nárast vlhkostí v dostatočnom rozsahu.Similar difficulties occur with additional complete inter-cladding insulation on steep roofs with vapor-proof pre-covering (eg roofing board on wooden formwork). The survey of the Institute of Building Physics at Fraunhof has shown that with internally installed vapor barrier barriers with a water vapor diffusion resistance (d value less than the diffuse equivalent 10 m air layer thickness, especially on roofs facing north) sufficient to achieve wood moisture that is not doubtful. Thus, an internally arranged vapor barrier can no longer absorb, for example, a convex-induced increase in moisture to a sufficient extent.
Podstata vynálezuSUMMARY OF THE INVENTION
S ohľadom na uvedené nevýhody je úlohou vynálezu vytvoriť na vnútornej strane parotesnú zábranu, ktorá je schopná pri rôznych okolitých podmienok a variabilite použitia zaistiť výmenu vodných pár medzi vzduchom vo vnútornom priestore a vnútrajškom stavebného dielu, ktorá ďalekosiahle vylúči poškodenie stavebného dielu vlhkosťou.In view of the above-mentioned disadvantages, it is an object of the invention to provide a vapor barrier on the inside which is able to exchange water vapor between the air in the interior and the interior of the workpiece in a wide variety of ambient conditions and variability of use.
Vnútorná parotesná zábrana podľa vynálezu, ktorá sa dá tiež označiť ako „na vlhkosť sa adaptujúca parotesná zábrana“ používa ako rozhodujúci materiál taký materiál, ktorý má difúzny odpor vodných pár závislý od okolitej vlhkosti a ktorý' má na použitie v budovách dostatočnú pevnosť v ťahu a tlaku.The interior vapor barrier according to the invention, also referred to as a "moisture-adaptive vapor barrier", uses as a critical material a material having a water vapor diffusion resistance dependent on ambient moisture and having sufficient tensile strength for use in buildings and pressure.
Materiál na parotesnú zábranu, použitý ako fólia alebo ako vrstva nanesená na iný materiál, má mať pri relatívnej vlhkosti parotesnú zábranu obklopujúcej atmosféry v rozsahu od 30 % do 50 % difúzny odpor vodných pár /hodnotu sd/ 2 až 5 m difúzne ekvivalentnej hrúbky vrstvy vzduchu a pri relatívnej vlhkosti v rozsahu od 60 % do 80 %, ktorý je typický napríklad pre letné mesiace, difúzny odpor vodných pár /hodnotu sd/( ktorý je menší ako jeden meter difúzne ekvivalentnej hrúbky vrstvy vzduchu.The vapor barrier material used as a film or as a layer applied to another material should have a vapor barrier at ambient humidity ranging from 30% to 50% water vapor diffusion resistance / value with d / 2 to 5 m diffusion equivalent layer thickness at relative humidity and at a relative humidity in the range of 60% to 80%, which is typical, for example, in the summer months, the water vapor diffusion resistance (value with d ) ( which is less than one meter of diffusively equivalent air layer thickness).
Tým sa dosahuje za zimných podmienok vyšší difúzny odpor vodných pár ako za letných podmienok. Tým sa zvýhodňuje vysušenie v letných mesiacoch bez toho, aby prívod vlhkosti v zimných podmienkach mohol dosiahnuť hodnotu, ktorá by mohla vyvolať poškodenie použitých materiálov a budovy.This achieves higher diffusion resistance of water vapor under winter conditions than under summer conditions. This favors drying in the summer months without the moisture supply in winter conditions reaching a value that could cause damage to the materials and building used.
Okrem dôvodov uvedených a pri nevýhodách stavu techniky sa vynález môže použiť aj pri kovových strechách alebo drevených konštrukciách a môže tu spôsobiť zlepšenie tepelnej izolácie a zníženie stavebných nákladov.In addition to the foregoing and disadvantages of the prior art, the invention can also be applied to metal roofs or timber structures and can cause thermal insulation improvements and reduced construction costs.
Ako materiál na parotesnú zábranu majúcu požadované vlastnosti sa môže použiť napríklad polyamid 6, polyamid 4 alebo polyamid 3, ktoré sú známe z publikácie BIEDERBICK K.- Kunststoffe - kurz und biindig, Vogel-Verlag Wiirzburg (Umelé hmoty - krátko a stručne, nakladateľstvo Vogel-Wúrzburg). Tieto polyamidy sa používajú ako fólie, ktoré imanentné majú požadované vlastnosti čo sa týka difúzneho odporu vodných pár. Navyše sa vyznačujú pevnosťami požadovanými na použitie v budovách, takže sa môžu používať bez dodatočných nákladov. Hrúbka fólie môže byť v rozsahu od 10 pm do 2 mm, výhodne v rozsahu od 20 pm do 100 pm.For example, polyamide 6, polyamide 4 or polyamide 3 which are known from BIEDERBICK K.- Kunststoffe - course und biindig, Vogel-Verlag Wiirzburg (Plastics - short and brief, Vogel publishing house) can be used as a vapor barrier material having the desired properties. -Wúrzburg). These polyamides are used as films which have the immanent properties required in terms of water vapor diffusion resistance. In addition, they are characterized by the strengths required for use in buildings so that they can be used at no additional cost. The film thickness can range from 10 µm to 2 mm, preferably from 20 µm to 100 µm.
Môžu sa však používať i iné materiály, ktoré nemajú dostatočnú pevnosť, môžu sa však nanášať na vhodné nosné materiály. Nosné materiály majú pritom prednostne nízky difúzny odpor vodných pár a požadované vlastnosti izolácie proti vlhkosti sa dosahujú v podstate nanesenou vrstvou.However, other materials may be used which do not have sufficient strength but may be applied to suitable support materials. The support materials preferably have a low water vapor diffusion resistance and the desired moisture-proofing properties are achieved by a substantially deposited layer.
Ako materiály pre nosič, prípadne nosiče, sa môžu používať vláknami zosilnené celulózové materiály, napríklad papierové pásy, fólie z plastového pradiva alebo perforované polyetylénové fólie.Fiber-reinforced cellulosic materials can be used as carrier or carrier materials, for example paper webs, plastic spunbonded films or perforated polyethylene films.
Môže sa takisto používať materiál nanesený na nosný materiál. Nanášanie sa môže uskutočňovať jednostranne na nosný materiál alebo tiež vo zvláštnych prípadoch môže byť materiál uložený sendvičovito medzi dvomi nosnými vrstvami. V tomto prípade je nanesený materiál chránený účinne z obidvoch strán proti mechanickému poškodeniu a zaručuje preto požadovanú difúziu vodných pár počas dlhšieho času.A material applied to the carrier material may also be used. The application can be carried out unilaterally on the carrier material or, in special cases, the material can be sandwiched between two carrier layers. In this case, the deposited material is effectively protected from both sides against mechanical damage and therefore guarantees the desired water vapor diffusion over a longer period of time.
Môže sa takisto vytvárať niekoľko takých vrstiev nad sebou.It is also possible to form several such layers one above the other.
Na nanášanie na nosný materiál sa môžu používať rôzne látky a materiály. Tak sa môžu napríklad vhodným spôsobom nanášať polyméry, napríklad modifikované polyvinylalkoholy. Pritom sa odlišuje difúzny odpor vodných pár, podľa DIN 52 615, o viac ako desatinnú mocninu pri suchom a mokrom okolí.Various substances and materials can be used for application to the carrier material. Thus, for example, polymers such as modified polyvinyl alcohols can be suitably applied. The water vapor diffusion resistance, according to DIN 52 615, differs by more than one decimal in dry and wet environments.
Môžu sa na nanášanie na nosič používať takisto disperzie plastov, metylcelulóza, alkyd ľanového oleja, kostný glej alebo proteínové deriváty.Plastic dispersions, methylcellulose, linseed oil alkyd, bone size or protein derivatives can also be used for application to the carrier.
V prípade jednostranného nanesenia na nosný materiál sa tieto môžu nanášať na tej strane, na ktorej nie je nutná ochrana proti mechanickým vplyvom. Montáž vynálezeckej izolácie proti vlhkosti sa v tomto prípade môže uskutočňovať tak, že chrániaci nosný materiál je na strane privrátenej alebo odvrátenej od priestoru.In the case of one-sided application to the support material, these can be applied on the side on which protection against mechanical influences is not necessary. The installation of the inventive insulation against moisture can in this case be carried out in such a way that the protective support material is on the side facing away from the space.
Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
V nasledovnom bude vynález pomocou príkladu bližšie vysvetlený. V tomto tvorí parotesnú zábranu len fólia vytvorená z polyamidu 6. Boli uskutočňované pokusy s fóliou s hrúbkou 50 pm. Použité fólie polyamidu 6 sa v súčasnosti vyrábajú firmou MF-Folien v Kempten, D.In the following, the invention will be explained in more detail by way of example. In this case, only a foil made of polyamide 6 forms a vapor barrier. Experiments were carried out with a foil having a thickness of 50 µm. The polyamide 6 films used are currently manufactured by MF-Folien in Kempten, D.
Hygrické chovanie pri laboratórnom pokuseHygric behavior in a laboratory experiment
Difúzny odpor pre parotesné zábrany, adaptujúce sa na vlhkosť, bol určený podľa DIN 52 615 v suchom rozsahu /3/50 % relatívnej vlhkosti (r.v.) a vo vlhkom rozsahu /50/93 % r.v,/, ako i v dvoch medzi nimi ležiacich oblastiach vlhkosti /33/50 % a 50/75 r.v./. Výsledok pre difúzne ekvivalentnú hrúbku vzduchovej vrstvy /hodnota sd/ parotesnej zábrany s hrúbkou 50 pm je, v závislosti od strednej relatívnej vlhkosti panujúcej pri pokuse, znázornený na obrázku 1. Medzi hodnotou sd v suchom a vlhkom rozsahu je rozdiel väčší ako desatinná mocnina, takže i za praktických podmienok vzduchu v priestoroch, ktoré sa pohybujú medzi 30 % a 50 % v zime a medzi približne 60 % a 70 % v lete, sa dá očakávať zreteľné ovládanie difúznych prúdov parotesnou zábranou.The diffusion resistance for moisture-adaptive vapor barriers was determined according to DIN 52 615 in the dry range / 3/50% relative humidity (RH) and in the wet range / 50/93% RH, as well as in the two areas lying between them humidity (33/50% and 50/75 RH). The result for a diffuse equivalent air layer thickness (value s d ) of a 50 µm vapor barrier is shown in Figure 1, depending on the mean relative humidity prevailing in the experiment. The difference between the value s d in the dry and wet ranges is greater than the decimal so that even under practical air conditions in areas that are between 30% and 50% in winter and between about 60% and 70% in summer, a clear control of the diffusion currents by the vapor barrier can be expected.
Priemyselná využiteľnosťIndustrial usability
Na základe výpočtov bolo dokázané, že strmé strechy s parotesným podpláštením môžu byť po zabudovaní 10 cm až 20 cm hrubej izolácie z minerálnych vlákien medzi krokvami aj pri izolácii proti vlhkosti na strane priestoru tak vlhké, že v priebehu niekoľkých rokov nevyhnutne vznikajú škody. Zvlášť je situácia kritická pri vysokej vlhkosti v priestore, keď napríklad kolíše medzi 50 % r.v. v januári a 70 % v júli, keď sú súčasne, vzhľadom na orientáciu na sever, zisky krátkodobého žiarenia malé. V nasledovnom sa preto uskutoční výpočtom odhad vplyvu na vlhkosť adaptívnej izolácie na dlhodobé hospodárenie s vlhkosťou takých konštrukcií za podmienok podnebia v Holzkirchen, a to pomocou spôsobu už opakovane experimentálne verifikovaného.Based on calculations, it has been shown that steep roofs with vapor barrier cladding can be so damp after installing a 10 cm to 20 cm thick mineral fiber insulation between rafters, even when insulating against moisture on the space side, that inevitably damage occurs within a few years. In particular, the situation is critical at high humidity in the room when, for example, it varies between 50% r.h. in January and 70% in July, when, at the same time, given the North orientation, short-term gains are small. In the following, an estimate of the effect on the long-term moisture management of such structures under the climatic conditions in Holzkirchen is therefore calculated by means of a method which has been repeatedly verified experimentally.
Na neizolovanú, k severu orientovanú strmú strechu (sklon 28°) s dreveným debnením, bitúmenovou lepenkou a škridlovou krytinou, ktorá je so svojím okolím v hygroskopickej rovnováhe, je na obr. 2 znázornené, po vstavbe medzikrokvovej izolácie vlhkostné chovanie bežnej izolácie a na vlhkosť adaptívnej izolácie proti vlhkosti, umiestnenej na strane priestoru. Hore je zaznamenaný priebeh celkovej vlhkosti v streche a dolu priebeh vlhkosti dreva dosiek debnenia za obdobie desiatich rokov. Zatiaľ čo vlhkosť strechy s bežnou izoláciou proti vlhkosti za ročných výkyvov rýchle narastá, pričom sa už v prvom roku vyskytujú hodnoty povážlivej vlhkosti dreva (>20 hmotn. %), nedá sa v streche, vybavenej na vlhkosť adaptívnou izoláciou proti vlhkosti, zistiť akumuláciu vlhkosti. V lete tu klesá vlhkosť dreva vždy pod 20 hmotn. %, takže nevznikajú obavy zo škôd spôsobených vlhkosťou.The uninsulated, north-facing steep roof (28 ° slope) with wooden shuttering, bitumen board and tile covering, which is in hygroscopic balance with its surroundings, is shown in FIG. 2 shows, after the installation of the inter-clad insulation, the moisture behavior of the conventional insulation and the moisture-adaptive moisture insulation placed on the side of the space. Above is recorded the course of total moisture in the roof and below the course of wood moisture of the formwork boards over a period of ten years. While the humidity of the roof with normal moisture insulation increases rapidly with yearly fluctuations, with values of a considerably moisture content of wood (> 20% by weight) already appearing in the first year, moisture accumulation cannot be detected in a roof equipped with adaptive moisture insulation . In the summer, the wood moisture always falls below 20 wt. %, so there is no concern about moisture damage.
Izolácia prispôsobujúca sa vlhkosti tak otvára možnosť izolovať cenovo výhodne strmé strechy v starej zástavbe bez veľkého rizika vzniku škôd.The moisture-adaptive insulation thus opens up the possibility of insulating cost-effective steep roofs in old buildings without much risk of damage.
