How to fix the vapor barrier



Materials protecting building structures from steam and moisture are called vapor barrier. As a vapor barrier can be used roll or sheet materials. The methods of attachment are different for them.





How to fix the vapor barrier


















You will need




  • - Construction stapler;
  • - self-tapping screws;
  • - slats;
  • - profile.




Instructions





1


Fasten the vapor barrier materials to the innerside of the room. If the walls are very thin, and the air temperature in winter time falls below 25 degrees, then the vapor barrier must be inside and outside the building.





2


Roll materials around the perimeterwalls with a construction stapler. Each next roll, start to untwist, making a lap over the previous tightness. If you do not plan further warming, use wood or plastic slats to secure the material.





3


Screw the scribers at a distance of 30 cm from each other. If you are covering the walls with heat-insulating materials on top of the vapor-insulation materials, vapor barrier not necessary. You will be mounted on racks at the same time and vapor barrier and thermal insulation.





4


To fix the sheet vapor barrier, installframe from the profile into which you will simply insert the sheets. Additionally, fix them with self-tapping screws. Place joints with PVC or isospan.





5


The vapor barrier of the ceiling is overlapped with the walls,which should be at least 20 cm. To effectively protect the ceiling from steam and moisture, and also significantly extend the life of the load-bearing structures, make steam insulation inside and out.





6


External insulation must consist of three layers,where the first layer will be a vapor barrier, the second - thermal insulation, the third - vapor barrier. Such triple protection will completely prevent the appearance of condensate, which will significantly extend the service life of wooden floors.





7


If the floors are made of reinforced concrete, thenthe more they need to be reliably protected from steam and moisture. If this is not done, then the apartment or house will always drip from the ceiling, especially if there is a significant change in the temperature regime on the street.
