Proper steam with their own hands .Device vapor barrier .Which side lay

Proper steam

moisture in the vapor state is present everywhere - it's part of the natural water cycle.Ignoring this factor in ensuring energy efficiency of buildings is unacceptable.It is known that waterlogging material reduces the thermal resistance of walls up to 30%.Today proper vapor barrier - an important part of the thermal protection of building object.

Why right?Because the steam that does not meet the standards, or installed incorrectly, resulting in loss of insulating layer properties in a year.The accumulation of moisture on the surface of the structure starts the process of their destruction.This applies to all materials.

Necessity parozaschity

There is another question: whether parozaschita do I need?It depends on many factors.the calculation itself is performed by SNIP 23-02-2003 dedicated thermal protection of buildings.The basic data for the wall structure serve him, floors, floor or other surface, and the climatic conditions.

This calculation is important also because that foreign producers vapor barrier materials calculated its permeability and strength for a warm - up with our - winters.And since the steam is only in the cold season, the examination of the material will be the most severe frost.

And it can withstand only the materials that are certified for our conditions.Yes, steam with their hands allows significantly reduce the cost of this process, but not at the expense of quality materials.

example, cheap Asian films contain plasticizers, which significantly reduce its adhesion to the adhesive fastening tapes basis.This means that after some time this pseudo steam will consist of separate pieces of material.

requirements parozaschite

• Paroizoliruyuschy layer must meet the following requirements.
• provide the calculated resistance to water vapor at a thickness of no more than 4 mm.
• Have heat resistance, eliminating the "drift" of the material on vertical surfaces at temperatures up to 50 ° C.
• Under the influence of positive and negative temperatures to maintain the calculated resistance to water vapor transmission and adhesion to a connecting tape or insulated surface.
• remains flexible, be continuous and a vapor in the joints.

material must have a manual installation.

Types vapor retarding materials

• glassine and roofing material.Traditional materials are sometimes used, and at present.Mounted on the flooring of boards or OSB boards.
• Films reinforced plastic.Used as a vapor barrier in the saunas, pools and bathrooms.
• Films polypropylene reinforced with anti-condensate simple and viscose fiber.It absorbs moisture, preventing its condensation.With the onset of warm season the moisture evaporates.These films are durable and not expensive.
• diffusion membranes, or "breathing".The most perspective view allows you to "breathe" a heater, do not allow the penetration of moisture from the inside to him.It does not require air gaps, can be single or double-sided.
• Special Materials: reflective film with an aluminum coating, polyethylene foam with aluminum foil - penofol.

conditions for effective parozaschity

As with all construction work, device vapor barrier begins with the preparatory work.Insulation should be dry.Surfaces must be cleaned of dust and dirt, to close up the gap, align the roll for a snug fit paroizoliruyuschego material and anchoring its rails.

absolute tightness - proper vapor barrier , it is a basic requirement.Tested on steam, serious objects using blower door, which creates a negative pressure.

Designated input cable harness and the ventilation valve - the weakest link.Not sealed the hole diameter and a few millimeters, and the installation of a vapor barrier does not justify itself.In full accordance with the laws of physics here is rush all the moisture out of the room.

Vapour proof layer of film material manufacturer always identifies and points to the correct orientation of the film during installation.

Where necessary to arrange vapor barrier

Parozaschita used to protect structures and insulation on surfaces that serve as a barrier between heated and unheated rooms.

1. Attic, attic and basement floors.
2. Exterior walls of heated space.
3. bathrooms, swimming pools, baths and saunas, kitchens.

This list can include other surface boundary between warm and cold air.An exception can be built of timber: wood itself currently proper vapor barrier and is capable to absorb excess moisture.On it no condensation.

protection wooden floor

Mandatory steam wooden floor over unheated basement, underground, or other unheated volume.She always arranged from the heated space.

stacked on the floor joists at 600 mm, between tightly stacked insulation, and already on logs - vapor barrier material.On him and laid topcoat.

When the device wooden floor on the concrete floor before installing the lag surface of the concrete floor covered with seal section with careful sealing of joints.

protection ceiling

There proper vapor barrier layer includes two ceiling parozaschity: on both sides of the insulation.Modern films like "Izospan" provide a vapor barrier is not insulated roofs.The special very solid film attached to the bottom of the rafters and prevents the ingress of moisture in the roof space.

protection wall construction

important stage in the building of protection - proper vapor barrier walls , both outside and inside.With insulation of walls inside the building is attached on top of the insulation film, the inside of the room.Strips of material glued tape, in addition to the frame counter-pressed, which is attached interior.

on the outer surface of the wall installation of the vapor barrier similar: close insulation film on the outside, and arranged clamping rails exterior finishing material.The film is attached from the bottom up, on the base produced 100 200 mm film to protect the abutment wall to the cap.

Orientation paroizoliruyuschego material

All of these works do not require special skills, but sometimes with their hands steam satisfied with the manufacturer's instructions of the material.If the film on both sides has the same structure and color, the workers are considered to be the two sides.

When the parties are different, it is necessary to carefully study the installation requirements.Rule, which side lay a vapor barrier , overall, if the film has a smooth and a rough surface, the rough side - that it will trap moisture - is located on the outside and smooth - a heater.Reflective film surface is always watching out: their smooth side facing the heater.

laying vapor barrier

Before buying a water vapor retarder material must be clear about what the design need to be protected.Species of it on the market quite a lot, so it is important to accurately determine the necessary.Only in this way will be clear, how to lay a vapor barrier and provide maximum protection.

In most cases, it should not prevent the penetration of moisture in insulation, so special attention should be paid to seams.Reliable bonding of the film to the substrate provides a fastener with a broad hat or furniture staples.
