Instructions for use IZOSPAN B and its features

Polymer films for vapor barriers create a protective buffer between the insulation and the interior space

Basic information about Izospane

The name of the material comes from the name of the company that produces it. It refers to several vastly different properties and purpose polymer films. All products of this brand are usually divided into three main groups:

• protecting against water and wind Izospan membrane A. They are widely used in roofing and facade works as protection elements of the roof structure, and the inner part ventilated facades by precipitation. When this film is able to pass through a steam outputting it outside. This property of these membranes gives moisture to form condensation on the insulation or parts truss roof system. Some species have a flame retardant treatment. The average water vapor permeability is determined near the index of 3500 g / m² per day. It must be said immediately that the material can not be used on the roof, having an angle of inclination less than 35 ° C. Mandatory requirement - the installation should be performed only under normal weather conditions;

Purpose In IZOSPAN - not afford to get a couple of rooms in the insulating layer and there form a condensate

• do not let the water and the film pairs are Izospan line B. Unlike its counterpart is mounted indoors. After all, his task - not to allow steam to enter the premises in the insulating layer and there form a condensate. Closed a membrane insulation slabs are always dry, which prevents them from plaque mold and fungal colonies. Usage Guide IZOSPAN Bbudet set forth in more detail;
• With Izospan intended not only to protect the insulation layer from the wind, humidity and steam, but also to create Additional warming effect due to a special coating which is able to reflect infrared rays. This greatly reduces the power consumption of the home, creating a good savings for heating. It has a structure consisting of two layers. One layer is always smooth and the other rough, it is better to hold condensate. The material is very waterproof and 1000 mm. water. Art. Its resistance to steam penetration is 7.0 Pa / mg.

Technical characteristics of the films Izospan:

Useful advice!Instructions for use IZOSPAN B suggests that in the case of a film break on any sharp objects, it can and must be repaired. For this fault location is sized special adhesive film.

All of these species at their differences, have a number of positive, their common characteristics:

• they are easy to install and is supplied in rolls form;
• not afraid of ultraviolet radiation;
• do not absorb moisture;
• their cost is well suited to anyone who is engaged in building or insulation of their homes.

Next consider in detail the instructions for use IZOSPAN B and its technical and qualitative characteristics, since it is this kind of membranes is the most popular, due to a very successful combination of consumer properties and prices.

The use of polymeric films in the arrangement of the roof increases its reliability and durability

Technical characteristics of the vapor barrier Izospan B

To this type includes dual-layer vapor barrier membrane that can not only restrain the moisture, but do not allow the pair to penetrate them. They are 100% polypropylene. These films are produced in rolls with a width of 160 cm. One roll may be coated with a surface area of ​​70 m². The density of the film is 70 g / m². These membranes are strong enough, because their load at break along the fiber is 128 N / cm, and transverse 104 N / cm.

Water vapor transmission rates are very low and are near the mark of 22.4 g / m² / day. Waterproof - 1000 mm. water. st., which is sufficient. UV-resistance is observed within 4 months of continuous exposure. Specifications vapor barrier Izospan B allow to apply it in a wide temperature range, which is from -60 to 80 ° C.

Instructions for use IZOSPAN B

Before using this material for the purposes of a vapor barrier should be familiar with some of the requirements for its installation:

• by coating of insulation, mounted on vertical or inclined surfaces, the work must be carried out carefully from the top down. Material strip is attached in the horizontal direction with an overlap of 15 cm. Special adhesive film allows to isolate the joints;
• any party to a heater Izospan B lay, not everyone knows. Meanwhile, it is very critical since improper stacking completely negates the effect of using this material. It is necessary to remember that the smooth side is always placed on a heater, and the rough is directed into the room;

Scheme correct application of the film to the vapor barrier in the process floor insulation using expanded clay

• attach the membrane to the surface to be protected with the help of sticks of wood, clamps and staple gun.

Since this vapor barrier material has broader applicability, we consider the particular installation on several types of surfaces. When you create a vapor barrier in the attic, the membrane may be attached to the rafters in two ways.

In the first case the film is fixed by bars to the cross section of not more than 5 cm on top of rafters. Thus insulation sheets remain inside. They should not be thicker than the rafters themselves.

In the second case, the film is attached to the sides of the rafters, skirting them, too, bars. Fine finishing the ceiling is already on top of the vapor barrier. It is worth remembering which side to put a heater Izospan B.

Izospan film placed under the insulation on top of the wooden floor lag

If vapor barrier subject to the roof of the attic before it is finally closed roofing material, it is more convenient to make on the underside of the rafters crate of rails for the installation of finishing. On her bed smooth membrane side up, fixed using a stapler and then impose between the rafters mats heat insulating material.

Instructions for use IZOSPAN B indoor It is combined with the technique of a heater mounted on the guide profiles. Instead of metal profiles, wooden beams thickness equal to or slightly larger than the thickness of insulation can be used. Profile fastened to the walls vertically, so that the distance between two adjacent strips is equal to the width of the insulation boards.

Plates inserted between the profiles and secured to the wall. The membrane itself has already fixed on top of these guide plates profiles or wooden bars. Web material attached horizontally overlapping 15 cm. After that close the wall with plasterboard or other sheet material.

Useful advice! at vapor sealing device for timber walls, They must be treated with antiseptic and remedy for insect pests. This will provide an additional guarantee of the quality of the works.

Izospan D: Instructions for Use

Besides the classic three kinds IZOSPAN, now on sale there are other variants, which have some additional properties. For example, high strength and low thermal conductivity IZOSPAN D, allows the use of this membrane for waterproofing flat roofs and even concrete floor. He is able to withstand much greater load than its predecessors.

Care should be taken about the integrity of the seams near the exit points of communications on the roof and at the junction of the vapor barrier sheets

Instructions for use IZOSPAN D in this case is very simple. The panels are rolled on a flat roof surface and overlapping placed 150 - 200 mm. The edges of the ribbon are connected Izospan SL. Placed on top insulation and constructing the roof. For waterproofing floor material is placed on the concrete foundation so that at least 10 cm is folded in its wall. Glued joints of the same tape. Above waterproofing poured concrete screed for leveling the surface to which the already laid topcoat.

The main point is to IZOSPAN IZOSPAN D and B which side to put a heater them. Improper installation can cost time and money spent in vain. Therefore, you must strictly adhere to the instructions provided.
