Briefly about the specifics of the vapor barrier device

Polymer films intended to stop fumes from penetrating the thickness of insulation systems are used to construct steam isolation. These are thin roll materials having very little, usually virtually no, vapor permeability. They become a dependable barrier in the way of warm air carrying suspended water because of their high structural density.

If we take into consideration the system of arranging the insulated roof from the side, the vapor barrier carpet is always laid as the first layer in the roof pie. It is his responsibility to first meet the couple and, if at all possible, to repel their attacks completely or to minimize the amount that can pass through a vapor barrier barrier.

If not, the water will seep into the insulation and eventually destroy the surrounding building structures as well as the thermal insulation. A fungus will proliferate within the system, rapidly expanding its colonies. The house cannot be shielded from heat loss by wet insulation. Heat losses are actively caused by soaked water.

If there is no damage to the vapor barrier films, they do not miss at all. However, if the bands were not properly glued during construction, steam may leak through the weak compounds of the material panels or through the panels themselves.

Only if the cold roof is waterproofed can you stop using adhesive tape. This enables you to perform the detailed styling. The waterproofing film’s panels are covered in below-up strips, which obstruct the underlying layer with each new strip. Water then flows like fish scales as a result.

While the arrangement for steaming protection varies slightly, the basic idea remains the same: water must drain through the insulating carpet without going back into the space or remaining in the insulation. The panels are installed across the rafter legs, but they begin at the ridge run rather than the cornice line as is the case with waterproofing organization.

It is evident that each underlying strip of a vapor barrier carpet overlaps the lower edge of the upper panel by 10 to 20 centimeters when viewed from the side of the room. In order for the glass or moisture that seeped into the insulation system to be down or to move with the air that is circulating, the indicated overlap is required.

To prevent moisture suspended in the air from penetrating through this extremely vulnerable area, the line connecting the vapor barrier film’s stripes along the overlap must be sealed. This is the tape that is required to glue the vapor barrier panels together. The appropriate tape to use for this purpose will depend on the installation and future use of the roof with the vapor barrier carpet.

Features of the structure of steam protection

The earliest known type of vapor barrier barrier was created by our ancestors using fatty clay. Its continuous layer was applied from the attic side to the ceiling overlap, and a layer of dry land was placed on top. The outcome was noticeably more effective than new thermal insulation options.

With time, pergamine took the place of clay and lacked any unique resistance to wear or outside forces. He was completely unfit for building the roof during the rainy season and in the heat, as he could not retain water on his body. Furthermore, it was prone to damage during styling, which led to a minor increase in the construction budget and the need to redo a significant portion of the work.

Initially, polyethylene films were used in place of brittle parchine, followed by their polypropylene equivalents. Nowadays, a broad variety of specialized vapor barrier materials with enhanced properties, enhanced resistance to mechanical stress and atmospheric conditions, and optimized strength qualities are available on the same polymer basis.

The three most prevalent categories into which all vapor barrier materials used in construction today can be categorized are as follows:

• Polypropylene films or polyethylene, including reinforced options. They are used mainly in the schemes of insulation of ceiling floors, where they are laid on a horizontal plane, therefore they do not need to glue. Used as waterproofing of cold roofs.
• Membrane with anti -condensate qualities. Polymeric materials with an internal rough surface established towards the movement of the fumes. The opposite smooth side confronts the seeping of water from the outside. Used in arrangement of attic.
• Foil membranes. Polymer films with foil on the inside, a layer of thermal insulation is often timed to the outer surface. They play the role of vapor barrier and material with reflex properties, are installed in Russian steam rooms, Finnish saunas and other rooms with similar humid-temperature operational regime.

Tape with an adhesive composition on one or both sides is used to adhere foil and anti-condensate panels against steam. Let’s examine the methods utilized, the location and timing of the gluing process, and the connections that are made.

General laying rules

A vapor barrier barrier needs to be installed correctly in order to fulfill its designated purpose. Vapor barrier materials are laid out as a roll rolls out, which is the primary regulation that must be strictly followed. Turning and rewinding the material is not at all necessary.

Furthermore, the manufacturer designates the size of the overlap and the side to lay on for ease of execution. In this instance, there’s no need to experiment. The system’s creators took care to consider and account for every detail.

Setting up a basement ventilation system is essential to preventing spontaneous condensate formation in the roof pie’s body. It is organized in the event that regular polypropylene and polyethylene films are laid prior to attic roof insulation. This is accomplished by creating ventilation ducts—perfume—by fastening the counterparty to the rafters from the premises.

Ventilation ducts are not required when insulated attic roofs are installed with membranes. These substances are permitted to come into direct contact with the insulation without running the risk of wetting it due to internal condensation systems.

Regardless of whether the material can withstand the pressure of a water column or not, it is best to wait for dry, calm weather before building any kind of steam protection. Steamed materials are fastened to rafters or reshetins; the maximum distance allowed between fixation supports is 1.2 meters.

The device’s actions consist of multiple comparable stages that are independent of the material utilized during construction:

• Rolling a vapor barrier membrane. The starting strip of the material is rolled across the rafters. They begin work from the line of the ridge run, continue with longitudinal lobes down to the cornice.
• Film mount to rafters. A vapor barrier barrier is attached to the rafter structure with glue, stapler brackets or galvanized nails with a large flat hat.
• Compliance with the output. When attaching to the rafters, it is necessary to form a small sag so that the material is not tightly pulled between the mounting points. "Sag" the membrane should be approximately 2 cm per meter. So it is necessary that with standard ascels for the lumber of the moves, they do not tear the film.
• The location of the overlaps. The materials of the material should overlap each other horizontally by 10 – 20 cm, vertically by 15 – 20 cm, depending on the recommendations of the manufacturer. Wools should be placed above the rigid elements of the rafter system.
• Thorough fixation. After the primary fastening of the membrane during the laying period, it should be captured by the installation of the crate.

The crate serves as the first in a series of ventilations needed to maintain the space between polymer material and the attic lining. It is constructed in front of a vapor barrier barrier. Simultaneously, the reshetins function as the foundation for the casing installation.

Types of adhesive tapes for vapor barrier

Keep in mind that the tape used to join the panels and film should come from the same manufacturer when selecting a vapor barrier material for a roof pie. Using products from different brands frequently results in little to no sticking or very little sticking.

In order to create a vapor barrier, a connecting tape is used. It stops capillary moisture from forming in the connection zone:

• packed nearby panels;
• fit to the elements passing through the roof – stoves, antennas, communication risers;
• fit to adjacent building structures, including parapets, panoramic windows, doorways, etc.

The conditions of the impending operation will determine which vapor barrier material is best for shielding structures from the fumes; these conditions must be considered in full before the acquisition. Furthermore, it is imperative that you thoroughly review the instructions provided for installing a vapor barrier to avoid unexpected problems down the line.

One -sided tape for dense connections

This kind of adhesive tape is used to join the vapor barrier material canvases by covering the edge of the overlap that is present on the adjacent panel that has already been installed.

A unilateral tape bearing the nomenclature name and the DELTA® logo Tape Fas 60/100 is a 6 centimeter wide strip with an adhesive acrylate composition on the working side and a base made of laminated cardboard. It is not permitted to adhere film materials composed of chlorparafin to recyclable plates using this tape. Installing it in bathrooms and swimming pools is not recommended.

Only work inside the equipped attic or other room is done with it. Ideal for attaching vapor barrier protection to adjacent wooden, plastic, or smooth metal surfaces.

An analogous product in the domestic product line is isospan SL, an adhesive tape intended for the hermetic joining of vapor barrier strips.

Self -adhesive self -expanding option

These goods are identified in the German manufacturer Delta’s line by a ribbon bearing the designation Delta-Kom-Band K 15. It is utilized in the construction of brick chimneys, ventilation shaft walls, and the spaces between neighboring structures in order to create a hermetic seal.

The tape is compressed in the condition that is presented to the buyer, resulting in a trading supply that is only 4 cm wide. However, after the material is straightened, the strip’s width increases to 17 cm. It is composed of foamed polyurethane, with an acrylate adhesive applied and reinforcement arranged on one side of the tape.

This kind of adhesive tape can be used to glue damp or even bare surfaces, making it appropriate for outdoor tasks. It is pressed to the wall by a rail after being first glued to the film.

Elastic self -adhesive tapes

Bitumen-tale unilateral tape Delta-Flexx-Band F 100 and Delta-Multi-Band M 60/M 100 are used to seal openings through the roof of communication risers, antennas, and narrow steel pipes.

These are all-purpose adhesive consumables that can be used externally or internally. When used in the layout of passageways, they counteract the linear movements of building elements in relation to one another and permit such movements without compromising the tightness of the equipped junction.

All insulating film types can be protected from damage with universal adhesive tape, but it is only appropriate for smooth surfaces. They are resistant to UV rays and other harmful elements of the atmosphere because they are made to perform external work.

One-sided tape bearing the label Isospan ML Proff that is resistant to UV light and atmospheric negative is among the products offered by Isospan.

Double -sided tape and their use

Butyl tape is used to make a double-sided, German-made tape that is resistant to atmospheric negativity and goes by the name Delta-Butyl-Band B 15. The tape with two sticky sides is used to seal vapor barrier cloths and remove flaws like cuts and breakthroughs.

When doing external or interior work, bilateral adhesive tape for insulating films is utilized. It works well for installing rafters, hard flooring, and attic to attic window arrangements. Installing clamping strips at junctions with building structures is necessary to guarantee precise fixation.

The isospan KL is one of the Russian adhesive tapes in the lineup with comparable features. This adhesive tape is applied to a rolling vapor barrier strip, backing away from the edge by the manufacturer’s specified amount. After gluing, the top is removed and the next vapor barrier cloth is applied. Initially, only the lower anti-adhesive paper is removed.

Metallized ribbons for vapor barrier barriers

Aluminum-coated tape is used to connect vapor barrier materials with a metallic side. The German roofing material brand’s product is known as Delta-Poly-Band p 100.

This tape is one-sided, composed of polypropylene, and has a metallic spray applied to the outside. With a width of 10 cm, this kind of adhesive tape has gluing capabilities that greatly surpass those of traditional tapes.

Comparable qualities set FL Termo isoppan apart in the Russian product line; the suggested adhesive tape lets you make a single heat-refracting plane that looks like a German product.

In rooms with an operational moist-temperature regime that is not standard, sticky ribbons with a metallized side work perfectly. The Finnish saunas and the steam rooms of Russian baths provide dry pairs with their own equipment. The application of adhesive tapes is done on low-fat, dried vapor barrier canvases.
