How to lay vaporizolation

Purpose of vaporizolation - protection of insulation and structures from moisture that contributes to the appearance of mold, fungus and reducing the life of structures. Installation of the steam barrier depends on the type of material and the species of the surface coated.

The vapor insulation material has no perforations - the less its ability to skip the pair, the better. To organize barriers to humidity use:

Polyethylene films - there are simple, reinforced "technonikol" or coated with aluminum foil "Penofol";
Polypropylene films or tissues "Nanosezol D" - more durable and resistant to ultraviolet;
Diffusion membranes "Izosun AM" - can control the yield output from the room.

With the inner insulation of the walls, the "deaf" vapor barrier is performed on top of mineral wool. In structures ventilated facades And for roofing "cake" uses a bulk membrane, which closes the insulation from the outside. Cold roof is protected by steamed rafter.

Bilateral films can be laid by any side. Anti-condensate membranes are mounted in a textile layer inside the room. Metallized material draws foil towards rooms. Stacking steam films are performed, focusing on the tips of manufacturers, because One company can produce multidirectional products.

For temporary fixation, membranes use construction staples or nails with wide hats. Reliable fastening is ensured using counterbags. On the roofing, the films are glued along the perimeter with double-sided ribbons, and to rough surfaces - by means of rubber glue.

Procedure for steam barrier wood floor:

A draft floor is prepared, wood structures are cleaned and coated with antiseptics.
The first layer of film is stacked to protect against dirt humidity, the roll is rolled by the lanes of the bracket of 150 mm, and the joints are sampled by assembly tape.
Between lags, there is a heater, tight and without cracks.
It is a second layer of vapor barrier so that the ventilation gap remains.
