Abstract

Undertaksduk.

Description

Foreliggende oppfinnelse vedrører en undertaksduk omfattende
i det minste en vanntett folie, fortrinnsvis av armert plast.
For å redusere byggeomkostningene har man i de senere år i
stor utstrekning benyttet undertak av en sterk, tett og vann-
tett armert plastfolie. Denne duken kan legges direkte på
sperrene og hindrer inntrengning av vann ved sterk vind, de-
fekte taksten eller andre defekter i det ytre takbelegg.
Hvis dette belegg av en eller annen grunn blir lagt opp med u-tilstrekkelig utluftning kan det imidlertid oppstå kondens på undersiden av plastmembranen. Denne kan arte seg som dråpe-dannelse og kan være uheldig.
Oppfinnelsens hensikt er således å hindre slik kondens eller i
det minste å redusere dens skadelige virkninger.
Dette oppnås ifølge oppfinnelsen ved en undertaksduk av den innledningsvis nevnte type hvor det karakteristiske er at folien er forsynt med et fuktabsorberende sjikt.
Ytterligere fordelaktige trekk ved oppfinnelsen fremgår av under-kravene og av følgende beskrivelse av de utførelseseksempler som er vist på vedføyede tegning. Her viser fig. 1 i forstørret målestokk et skjematisk snitt gjennom en undertaksdel ifølge oppfinnelsen, mens fig. 2 viser en modifikasjon av undertaksduken på fig. 1.
På tegningen angir 1 en vanntett plastfolie som er armert med et trådnett 2. Folien 1 er på den ene side belagt med et isolerende, f uktabsorberende sjikt 3 som med fordel kan bestå av cellulose-!-
I
materiale i form av fibre eller fibermatter. !
j Belegget vil absorbere fuktighet og gi den fra seg igjen i form
av vanndamp og ikke i form av dråper. Belegget vil også virke isolerende og dermed minske muligheten for kondensasjon.
Beleggets absorbsjonsevne vil stort sett være direkte proposjonal med dets tykkelse, resp. vekt pr m 2for samme type fiber. Som vist på fig. 2 kan isolasjonsevnen økes ved å anordne et isolerende materiale 4 mellom folien 1 og fibermatten 3. Det isolerende materialet 4 kan med fordel bestå av en skumplast.
