No Complication for the Vapor Barrier Installation

Installation of vapor barrier is required during the construction of residential buildings: the membrane protects the insulation from vapors emanating from the room inside the roofing space; on the other hand, the vapor barrier film prevents condensate from entering the room. Improper installation of the membrane (the wrong side) is fraught with the accumulation of an excessive amount of vapor inside the room, as well as uncontrolled access of moisture directly under the roof. Insulation gradually soaked with water and cease to perform its functions, and the material of the sheathing and roofing will undergo intensive destruction.

Which side to mount vapor barrier

Special materials for vapor insulation are produced in the form of single-layer films, foamed polyethylene with metallized coating and two-layer membranes. Their installation has some differences, which is why it is not easy to figure out which side to attach the vapor barrier:

Polypropylene film is installed with a rough surface to the under-roof space. Such an insulation texture will collect moisture, which will evaporate through the ventilation gap. However, its value must be at least 20 mm. If the film is the most common (polyethylene), its sides will be identical.With the Vapor barrier installation this really important.

  • The two-layer membrane is laid with a smooth side to the insulation. For ease of use, manufacturers often put on the wrong side of the fabric special marking.
  • One-sided laminated polypropylene is also guided by a smooth surface to the insulation.
  • The foil side of the special film is turned to the insulation.
  • Given the variety of vapor barrier materials in the construction market, it is difficult to compile a comprehensive guide to their installation. Detailed information is usually contained in the instructions supplied by the manufacturers. But still, there are two more general rules:
  • If the instruction is obscure, and the film is painted in different colors, the lightest tone should be turned to the insulation.
  • Many materials are rolled up in a roll so that the side that turned down when it is rolled out can be immediately laid on the thermal insulation.

The main stages of installation

For the pitched roof there is a certain sequence according to which a high-quality vapor barrier is established. It is mounted after laying the insulation, on the surface of which there must be no defects. Bars for lathing are treated with antifungal compounds, after which a pre-calculated amount of film is prepared (covered area +15%) and the following:

  • construction stapler;
  • special double-sided tape for insulating and fastening cloths;
  • construction knife / clerical;
  • self-tapping screws;
  • roulette;
  • unilateral adhesive tape for joints, defects and cracks (of the same manufacturer);
  • screwdriver;
  • pencil;
  • scissors.

On the rafters, between which the insulating plates are laid, fill the bottom of the sheathing of the two boards. Stick a strip of special tape with two adhesive sides. Cut the roll into webs of appropriate length. Then, starting from the bottom of the crate, lay the membrane horizontally by marking up on the insulation, slightly pulling the cloth.

The risk of micro sleep rises with the rising temperature inside the car

The borderline is 25 ° C after overcoming, the risk of falling asleep behind the wheel increases significantly. Reduce the temperature and reduce the risk of air conditioning. Most drivers not only know how to use it properly, but also how to take care of it regularly. Additionally, the air conditioner does not require care only during the summer months, but you also need to maintain it in winter. In order to know more about Air conditioning repairs Geelong, you can always seek help from the web portals. A couple of years ago air conditioning was the privilege of higher class cars. Today, air conditioners are also equipped with cheaper models. Unfortunately, not every car owner with air conditioning can use it and take care of it properly.

Air conditioning in the car needs regular maintenance

Drivers who do not care about air conditioning and do not deal with regular maintenance are making a mistake. Non maintained air conditioning not only works poorly but also becomes a seedbed of mold, microbes, bacteria and viruses. And this “cocktail” is all breathed in the car every time air conditioning is running in the car. The working air conditioning system removes moisture from the evaporator (which is usually located under the dashboard of the car) and then condenses. And the evaporator also detects impurities sucked from the outside.

Shutting down the air conditioning a few minutes before stopping is recommended

The evaporator can dry out and the dry environment is no longer “attractive” for microorganisms and is very difficult to survive. In principle, we distinguish two ways of maintaining air conditioning. The first is technical maintenance to ensure its functionality that the air conditioner is really cool and cool enough. The second is maintenance in terms of health and cleanliness.

Smelly air conditioning needs service

If the interior of the car is feeling dizzy, air conditioning is unlikely to be in the best condition and need to either go to the car service or treat the air conditioner at home. It is advisable to keep the air conditioner clean and perform maintenance at least once a year preferably in the spring before the summer season. If the air conditioner is used intensively for most of the year, it is advisable to carry out the maintenance twice a year.

Take care to disinfect the air conditioner

To make air conditioning in your car health conscious and “fragrant”, you need to clean it regularly. Perhaps the best known and most common way of cleaning is spraying foam, which is applied directly to the evaporator. The long tubing “just” is inserted into the exhalation of the heater and spraying. The foam must rest on the evaporator that cleanses it. This is not always the case it is not possible to see where the foam falls.
