"Izospan B": instructions for use for walls, floor, ceiling

“Izospan B”, the instructions for use for roofing, floors, walls, etc., which will be discussed in this article, is one of the highest-quality domestic vapor insulators. Its advantages can be attributed primarily to the strength and ease of installation. This material is produced by the company “Geksa”, whose headquarters is located in the Tver region.

Varieties of material "Izospan"

At the moment, LLC “Geksa” produces several varieties of this material:

  • "Izospan A". This film is designed to protect all types of insulation from atmospheric moisture and wind.
  • "Izospan A. M" - a three-layer diffusion membrane that is installed directly on the insulation.
  • "Isospan A. S.". In terms of performance, this type of insulator is almost identical to the previous one, but has a slightly lower level of vapor permeability.
  • "Izospan AQ proff".The main advantages of this film include increased tensile strength.
  • "Izospan With". The membrane is designed for installation mainly from inside the premises. In some cases it is allowed to use it outside.
  • "Izospan D". Multifunctional film with anti-condensation coating.
  • "Isospan B". Instructions for use of this material allows for use to protect the insulation from the inside of the room and outside.

The last type of vapor insulator of this brand is currently one of the most popular. Further in the article we will deal in detail with what advantages and disadvantages it differs in and how it is used.

Pros and cons of the film "Izospan In"

The main advantages of this material include:

  • Strength. The film of this variety is not torn during installation and serves for a very long time.
  • Reliability. At use of this material the heater remains dry under any circumstances.
  • Versatility. Izospan V can be used for any kind of insulation for all, without exception, constructions.
  • Ecological cleanliness. The films of this manufacturer do not emit any harmful substances into the air.
  • Practicality.
  • Fireproof.
  • Ease of installation.

Due to its unusual structure and structure, the material “Izospan V”, the instructions for use of which will be given below, perfectly ensures the weathering of the accumulated condensate, significantly improves the insulating qualities of the “cake”, increases the service life of structures of buildings and structures. When it is applied, fungus and mold are not formed on the walls, and the insulation always remains dry.

Scope of use

In the cold season, the temperature difference in the living room and on the street is very large. As a result, moisture vapors, which are always present in the air of the rooms, condense on the enclosing structures, and if they are warmed, they are directly on the insulator. As a result, mineral wool, glass wool, etc., become wet and lose most of their warming properties. To prevent this from happening, vapor barrier membranes are used. This material is installed on top of the insulation from the side of the room and prevents the penetration of moisture into it.

The “Isospan B” membrane, the instructions for use (“C”, by the way, is a type used in approximately the same way and in the same cases) which is almost identical to that of other types of heat insulator, can be installed during insulation:

  • "Pie" mansards, attics, as well as roofs outside,
  • the walls inside and outside the street
  • floors - attic and mansard
  • floor.

It is possible to use this material when warming buildings for any purpose and any heights. Excellent "Izospan B" for protection against moisture of such types of insulation, such as mineral wool, polystyrene foam, polyurethane foam coatings, etc.

Features of the mother

Represents "Izospan In" a translucent film with a two-layer structure. One side of it has a smooth, and the second - a rough surface. Due to the presence of the texture, condensate is retained on the surface of the material, not flowing down, and very quickly disappears. Accordingly, the moisture does not penetrate into the thickness of the “cake” that warms the construction. As a result, the formation of fungus on wood and its rotting, as well as rusting of the metal elements of the protected surface are prevented.

General installation rules

How to install "Isospan B" correctly? Instructions for use (location in the "pie" below) from the manufacturer requires mandatory compliance with the following requirements:

  • Fastening on vertical and inclined structures - roofs, walls, partitions - is made from top to bottom. Stripes while stacked in a horizontal direction.
  • Overlap is made at least 15 cm.
  • For reliability, the joints are glued with a special adhesive tape.

izospan instructions for use with

Mounted "Izospan B" smooth side to the heater, rough - in the direction of the room. For fixing, you can use wooden bars, clamping strips or staplers. In this case, a reliable and effective protection will be arranged using the vapor barrier “Izospan B”, the instructions for use (see the photo of the correct installation on the page), which is usually attached to the roll.

Use of material for attic insulation

In this case, the plates of the insulation itself are inserted between the rafters in advance. Further, “Isospan B” is stretched. Instructions for use (attic walls, not insulated with a film of this type, it is impossible to insulate properly, as you understood) in this case:

  • Fix "Izospan" right on the rafters. Usually, the fastening is done in 3-5 cm thick bars, stuffed along the legs from above. Sometimes used and thin clamping plate (two). In this case, "Isospan B" is fixed on both sides of each rafter. The second method is also quite reliable.In addition, when using it, the attic space is saved. However, it is possible to fasten the material in this way only when the thickness of the rafter legs is at least 2-3 cm higher than the thickness of the insulation boards.
  • On top of the tensioned vapor barrier, a fine finish is installed (wall paneling, drywall, edged board, plywood, etc.). Attach it with the first method of fixing "Izospan B" on the bars. In the second - on the rafters. As a result, a ventilation gap is formed between the finishing and the vapor barrier, which ensures fast drying of the condensed water.

"Izospan V": instructions for use for insulation of roofs

When assembling the “pie” of roofs, the material is attached in about the same way as in the first case. However, first the vapor barrier itself is fixed. They fix it from the side of the attic with staplers or by mounting the inner horizontal batten for fine finishing from a narrow board in increments of 50-80 cm.

Next, between the rafters on a paroizolyator are laid slabs of mineral wool or polystyrene foam. To fall inside, in the attic, they will not be due to the crate. Sometimes, instead of the latter, ordinary wire is used.It is stretched from the side of the attic in such a way that the insulation plates will subsequently firmly hold between the rafters.

After installing mineral wool on the rafters, a waterproofing pad is attached (with a slight sag). Fix it bars, which are subsequently packed transverse crate. On it, in turn, the selected roofing material is fastened.

Use for walls from the room

Most often, this vapor barrier is used to insulate exactly the vertical walls enclosing structures from the inside. Next, we will discuss in detail how the “Izospan B” is set in this case. Instructions for use for its walls are:

  • First, a bar is fastened to the surface, the width of which is equal (or slightly larger) to the thickness of the insulation. When used for finishing plasterboard plasterboard, a metal profile can be used.
  • Next, set the slabs mineral wool or polystyrene foam.
  • On top of them - on bars, rails or staplers - is fixed a vapor barrier “Izospan V”.
  • Further fine finish is mounted.

Use of material for wall insulation outside

When assembling the “cake” to isolate it from the street, the procedure will be reversed. That is, first the lathing of a 3 cm thick bar is fastened to the walls (to provide a ventilation gap). Then a paroizolator “Izospan B” is pulled over it. Next, a counterbribe. The heat insulator is mounted between its elements. A waterproofing film is fastened on top of it, and then a fine finish (wall paneling, siding, etc.).

This is how the steam isolator “Izospan V” is usually mounted outside. Instructions for use for the walls of this material, discussed above, however, are given mainly for finishing wooden buildings. The fact is that the board, timber and log "breathe" and very easily let moisture vapor from inside the rooms to the outside. Concrete and brick walls of vapor retain much better, and therefore the insulating membrane in this case is rarely used.

The method described above is used to sheathe usually cobbled or plank smooth surfaces. It is allowed to fasten the paroizolyator on the timbered lath without pre-stuffing the sheathing. That is, right on the wall. Ventilation in this case will provide clearance through the junction of the logs.

In this case, it is also necessary to provide a ventilation gap. Pre-between the lags fit waterproofing layer. Next, install insulation plates. Then, by fixing with bars, a vapor isolator “Izospan B” is attached. Further the cut or batten is mounted.

Warming of garret and interfloor overlappings

And in this case “Izospan V” is very often used as a vapor barrier. Instructions for use for the ceiling of this material almost repeats the recommendations for installing it on the floor. From the side of the attic - when constructing a residential attic - it is mounted in exactly the same way. However, this vapor barrier is usually attached to the ceiling from below. In this case, it is fixed to the beams before mounting the casing. For fastening, as well as in all other cases, bars of small thickness are used. The ceiling board is mounted directly on them.

Useful tips

So, the above were considered the main recommendations for the installation of such a material as "Izospan B" (instructions for use). Ceiling, by the way, this applies primarily.The fact is that this part of the house, which is not isolated in this way, cannot either be properly insulated or finished. The same can be said about the walls or the floor. Next, we will give some tips that may be useful to someone when using the material of this brand for vapor barrier construction of the building:izospan instructions for use for sex

  • Wooden walls before laying the material must be treated with antiseptic compounds. The moisture between the film and the wood dries quickly enough. However, make sure it does not hurt.
  • It is also worth treating wood with insect repellent. To do this after installing the "pie" will be impossible.
  • Material "Izospan B", as already mentioned, is very durable. However, sometimes it still happens that the film is damaged by any sharp structural elements as a result of careless actions, etc. The broken places must be repaired using special tapes with a sticky layer or glue intended for this purpose.

As you can see, the “Isospan B” vapor insulator, the instructions for use of which are given in the article, are very reliable and easy to install.Its cost is not too high, and it considerably surpasses traditional polyethylene film in performance. Therefore, it is certainly worth using it to protect the insulation in residential premises from moisture.
