Izolácia proti vlhkosti použiteľná ako tepelná izolácia budovInsulation against moisture usable as thermal insulation of buildings
Oblasť technikyTechnical field
Vynález sa týka na strane priestoru usporiadanej izolácie proti vlhkosti využiteľnej pre tepelnú izoláciu budov, najmä pre tepelnú izoláciu novostavieb a pre sanáciu starých budov.The invention relates to the space-side insulation provided 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
Pre zníženie vzniku kysličníka uhličitého pri vykurovaní budov sa uskutočňujú pri stavbe nových budov a proti sanácii starých stavieb opatrenia pre tepelnú izoláciu. Z hľadiska stavebníka vždy ekonomická rozvaha so zreteľom tu platí tiež pre otázku stavebných nákladov. Naviac je pritom podstatným faktorom vonkajší vzhľad budovy, ktorý predstavuje obmedzenie skutočne možného. 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 k možnej difúzii pár najmä v zimných podmienkach zaisťovať vnútornou izoláciou proti vlhkosti. 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 pre priehradovú konštrukciu.In order to reduce the production of carbon dioxide in the heating of buildings, measures for thermal insulation are carried out in the construction of new buildings and against the remediation of old buildings. From the client's point of view, the economic balance with regard to the construction costs always applies here. In addition, the external appearance of the building is a significant factor, which constitutes a restriction on what is actually possible. 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 timber frame structure must be ensured by internal insulation against moisture, especially in winter conditions. 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 u strmých striech s parotesným predkrytím /napríklad strešnou lepenkou na drevenom debnení/. Šetrenie inštitútu fyziky stavieb vo Fraunhofe preukázalo, že pri vnútorne osadených izoláciách protiSimilar difficulties occur with additional complete inter-cladding insulation in steep roofs with vapor-proof pre-covering (eg roofing board on wooden formwork). Investigations of the Institute of Building Physics in Fraunhof have shown that in internally insulated
-2vlhkosti, s difúznym odporom vodných pár /hodnotou^/, ktorý je menší ako difúzne ekvivalentná 10m hrúbka vzduchovej vrstvy, najmä u striech smerujúcich k severu, nie je vysušenie dreveného debnenia v lete dostačujúce k tomu, aby sa dosiahla vlhkosť dreva nevzbudzujúca pochybnosti. Tak už nemôže vo vnútri upravená izolácia proti vlhkosti odvádzať napríklad konvexiou vyvolané nahromadenie vlhkosti v dostatočnom rozsahu.In the case of moisture, with a water vapor diffusion resistance (^ value) that is less than the diffuse equivalent 10 m air layer thickness, especially for north-facing roofs, drying the wood shuttering in summer is not sufficient to achieve wood moisture of no doubt. Thus, for example, a convex-induced accumulation of moisture to a sufficient extent can no longer be removed by the moisture insulation provided therein.
Podstata vynálezuSUMMARY OF THE INVENTION
S ohľadom na uvedené nevýhody je úlohou vynálezu vytvoriť izoláciu proti vlhkosti pre vnútorné priestory, ktorá je schopná za rôznych okolných podmienok a variabilné pri použití, zaistiť výmenu vodných pár medzi vzduchom v priestore a vnútrajškom stavebného dielu, ktorá ďalekosiahle vylúči poškodenie stavebného dielu vlhkosťou.In view of the above disadvantages, it is an object of the present invention to provide an interior moisture insulation which is capable of varying under ambient conditions and variable in use, providing water vapor exchange between the air in the space and the interior of the component which largely eliminates moisture damage to the component.
Vynálezom je úloha riešená znakmi uvedenými vo význakovej časti patentového nároku 1.The invention is solved by the features set forth in the characterizing portion of claim 1.
Ďalšie úpravy a uskutočnenia vynálezu vyplývajú zo znakov uvedených v závislých nárokoch.Further modifications and embodiments of the invention result from the features set forth in the dependent claims.
Vynálezecká izolácia proti vlhkosti, ktorá sa dá tiež označiť ako na vlhkosť adaptívna izolácia proti vlhkosti používa ako rozhodujúci materiál, ktorý má difúzny odpor vodných pár závislý na okolnej vlhkosti a ktorý vykazuje pre použitie v budovách dostatočnú pevnosť v ťahu a tlaku.The inventive moisture insulation, which may also be referred to as moisture adaptive moisture insulation, is used as a critical material having a water vapor diffusion resistance dependent on ambient humidity and which has sufficient tensile and compressive strength for use in buildings.
Ako fólia alebo materiál nanesený na nosný materiál, má izoláciu proti vlhkosti pri relatívnej vlhkosti atmosféry obklopujúcej izoláciu proti vlhkosti medzi 30% a 50%, difúzny odpor vodných pár /hodnotu sa/ dvoch až päť metrov difúznej ekvivalentnej hrúbky vzduchovej vrstvy a pri relatívnej vlhkosti v rozsahu 60% až 80%, ktorá je napríklad typická v letných mesiacoch, difúzny odpor vodných pár /hodnotu s /, ktorý je menší ako lm difúzne ekvivalentnejAs a sheet or material applied to a carrier material, it has moisture insulation at a relative humidity of the atmosphere surrounding the moisture insulation of between 30% and 50%, a water vapor diffusion resistance / s value and a two to five meters diffusion equivalent air layer thickness and relative humidity in the range of 60% to 80%, such as typical in the summer months, a water vapor diffusion resistance (s value) that is less than 1m diffusely equivalent
-3hrúbky vzduchovej vrstvy.-3th Air Layer Thickness.
To spôsobuje, že za zimných podmienok sa dosahuje 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 results in a higher water vapor diffusion resistance 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.
Vynález sa môže, mimo už pri nevýhodách stavu techniky uvedených účelov použitia, použiť i u kovových striech alebo drevených konštrukcií a môže i tu spôsobiť zlepšenie tepelnej izolácie a zníženie stavebných nákladov.In addition to the disadvantages of the prior art application, the invention can also be applied to metal roofs or wooden structures and can also improve thermal insulation and reduce construction costs.
Ako materiál pre izoláciu proti vlhkosti s požadovanými vlastnosťami sa môže použiť napríklad polyamid 6, polyamid 4 alebo polyamid 3, ktoré sú známe z publikácie BIEDERBICK K.- Kunststoffe - kurz und bundig, Vogel-Verlag Wúrzburg (Umelé ' hmoty - krátko a stručne, nakladateľstvo Vogel-Wurzburg). Tieto polyamidy sa používajú ako fólie, ktoré imanentné majú požadované vlastnosti čo sa týka difúzneho odporu vodných pár. Naviac sa vyznačujú pevnosťami požadovanými pre použitie v budovách, takže sa môžu používať bez dodatočných nákladov. Hrúbka fólie môže byť v rozsahu od 10/zm do 2mm, prednostne v rozsahu od 20μπι do 100/xm.For example, polyamide 6, polyamide 4 or polyamide 3, which are known from BIEDERBICK K.- Kunststoffe-Course und Bundig, Vogel-Verlag Wurzburg (Plastics - short and concise, Vogel-Wurzburg publisher). 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 may be in the range of 10 µm to 2 mm, preferably in the range of 20 µm to 100 µm.
Môžu sa však používať i iné materiály, ktoré nevykazujú 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 which do not exhibit sufficient strength may be used, 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 umelohmotného pradiva alebo perforované polyetylénové fólie.Fiber-reinforced cellulosic materials can be used as carrier or carrier materials, for example paper webs, plastic fiber 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 byťA material applied to the carrier material may also be used. The application can be carried out unilaterally on the carrier material, or else in special cases
-4materiál 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 dlhej doby.-4 material 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 long 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.
Pre 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 diffusion resistance of water vapor, according to DIN 52 615, differs by more than one decimal in dry and wet environments.
Môžu sa pre nanášanie na nosič používať takisto disperzie umelých hmôt, methylcelulóza, alkyd ľanového oleja, kostný glej alebo proteínové deriváty.Plastic dispersions, methylcellulose, linseed oil alkyd, bone size or protein derivatives can also be used for 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. Pritom tvori izoláciu proti vlhkosti len fólia vytvorená z polyamidu 6. Boli uskutočňované pokusy s fóliou o hrúbke 50μπι. 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 film made of polyamide 6 forms a moisture barrier. Experiments were carried out with a film having a thickness of 50μπ. The polyamide 6 films used are currently manufactured by MF-Folien in Kempten, D.

Výsledok pre difúzne ekvivalentnú hrúbku vzduchovej vrstvy /hodnota s / izolácie proti vlhkosti o sile 50/j.m je, v závislosti na strednej relatívnej vlhkosti panujúcej pri pokuse, znázornený na obrázku 1. Medzi hodnotou s 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 spôsobené použitou izoláciou proti vlhkosti.-5 / 50/93% r./ as well as in the two relative humidity regions (33/50% and 50/75 r./). The result for a diffuse equivalent air layer thickness / s value / moisture insulation of a force of 50 µm is shown in Figure 1, depending on the mean relative humidity prevailing in the experiment. The difference in the dry and wet ranges is greater than the decimal, thus, even under practical air conditions in areas that are between 30% and 50% in winter and between about 60% and 70% in summer, a distinct control of the diffusion currents caused by the moisture insulation used can be expected.
Priemyslová využiteľnosťIndustrial usability
Šetrenie výpočtami dokázalo, že strmé strechy s parotfesným podpláštením môžu po zabudovaní 10 cm až 20 cm silnej izolácie z minerálnych vlákien medzi krokvami, môže byť i 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 k orientácii 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.Calculation has shown that steep roofs with vapor-proof cladding can, after installation of 10 cm to 20 cm thick mineral fiber insulation between the rafters, be so damp even when insulated against moisture on the space side that damage will inevitably occur 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, while 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.
Pre 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 obrázku 2 znázornené, po vstavbe medzikrokvovej izolácie vlhkostné chovanie bežnej izolácie a na vlhkosť adaptívnej izolácie proti vlhkosti, umiestnenej na strane priestoru. Hore je zaznamenaný priebehFor a non-insulated, north-facing steep roof (28 ° pitch) with wooden shuttering, bitumen board and tile covering, which is in hygroscopic equilibrium with its surroundings, Figure 2 shows the moisture behavior of conventional insulation and adaptive moisture after installation of the interlayer insulation. insulation against moisture, located on the side of the space. The progress is recorded at the top

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 hm.%/, nedá sa v streche, opatrenej na vlhkosť adaptívnou izoláciou proti vlhkosti, zistiť akumuláciu vlhkosti. V lete tu klesá vlhkosť dreva vždy pod 20 hm.%, takže nevznikajú obavy zo škôd spôsobených vlhkosťou.-6 total moisture in the roof and down the course of moisture wood formwork boards over a period of ten years. While the humidity of the roof with normal moisture insulation increases rapidly with annual fluctuations, with already a significant moisture content of 20% w / w in the first year, moisture accumulation cannot be detected in the roof provided with moisture-adaptive moisture insulation. In summer, the wood humidity always falls below 20% by weight, so there is no concern about moisture damage.
Izolácia prispôsobujúca sa vlhkosti tak otvára možnosť izolovať cenove 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.
