Isoplastic: technical characteristics. Isoplast EPG and EKP

Izoplast today is a well-known and popular roofing material. It is worth more than roofing material, but it differs much better performance characteristics. Several types of this coating are available, differing mainly for their intended purpose. Different companies produce isoplast.

What is the material

Isoplast is sold, the technical characteristics of which are given below, in rolls of width in meters. The length of the strip is 10 m. Outwardly, this material resembles an ordinary roofing material. However, the basis in it is not cardboard, but fiberglass or polyester. Hence its increased tensile strength. On both sides, the substrate is covered with bitumen, with the ADP polymer, PPI or analogous polyolifins added to it. From below (and sometimes from above) the strip is glued with a protective film. During installation, it is simply removed. On some varieties, a scaly, coarse or fine-grained covering is applied from above.

Advantages of the material

The advantage of this type of roofing can be attributed to the following:

• Ease of installation. Stacking can produce two people.
• Tensile strength and appearance of cracks. When stacking, you do not need to be especially careful. It is rather difficult to break isoplastic (in contrast, for example, from roofing felt).
• Resistance to temperature changes. You can work with this material even in very cold weather.
• Durability. Isoplastic can last more than twenty years.
• Resistance to damage by bacteria.
• Environmental Safety.
• Full waterproof.
• Light weight. Lifting rolls on the roof, and also transport them very easily.

Disadvantages of the material

To the minuses of this type of roofing protection can be attributed only a fairly high cost. However, given the fact that the isoplast serves for a very long time, this deficiency is not very significant. Also, the disadvantage of this material is its vulnerability to sharp and cutting objects. Therefore, some caution in its packing and operation must still be observed.

Isoplastic: technical specifications

Of course, before you buy the material, you should find out exactly what properties it has. Below in the table we bring to your attention its main technical characteristics.

Varieties of material

When covering the roof with any kind of roll coatings, usually for reliability, several layers are arranged. The isoplastic is not an exception in this respect. Most often, 2-3 layers are placed on the roof of the houses. In this case, the lower ones, in contrast to the upper ones, do not have. Depending on the purpose, the material is thus divided into the letters "P" (lining) and "K" (roofing). The first is used in the lower layers. For the upper structure, a roofing isoplast should be used. Technical characteristics of both varieties are given in the table above. They are valid for all material modifications. As you can see, the reliability of this roofing is very good.

Isoplast EPG: technical specifications

As can be judged by the marking, this material is used in the lower layers of the coating. Its basis is polyester. The two letters "p" are used in the marking because both the bottom and the top of the isoplast strip of this type are covered with a polyethylene film. Most often, a variety of EPP is used to repair the roof, as well as to cover horizontal roofs. After the letters in the marking of the isoplastic, there are usually numbers (for example, 4.0). They denote the weight of a square meter of strip. That is, the larger the number, the thicker the waterproofing. Thus, the EPS isoplastic 4, the technical characteristics of which correspond to the properties of the "P" group presented in the table, is of a lesser thickness than the material marked with the number 5.

HDPE isoplastic

The scope of this version is the same as that of EPP. The only difference is that HPP is made on the basis of non-polyester, and glass fiber. Polyethylene film, with which the strips are coated on both sides, prevents the gluing of rolls during storage and transport, even in hot weather. Having bought the material, are disappointed as it sometimes happens when buying a roofing material, you will not.

Isoplastic EMF

This modification of the material is isoplastic "P" (technical characteristics are the same as for all lining varieties) is also used in the lower layers of the carpet. But in this case the front side of the strips is not covered with polyethylene film, but sprinkled with fine quartz sand. The use of such a material increases the reliability of the entire coating as a whole.

Isoplastic EKP

The material of this variety is used as the finishing layer in the roofing carpet. For the lower layers it can not be used. On top of the isoplastic ECP, the technical characteristics of which allow it to be used for all types of roofs, can be treated with scaly (vermiculite) or coarse-grained shale powder. This significantly increases the resistance of the surface to adverse natural factors, and also extends the service life of the roofing carpet. Bottom bands are covered with a protective film. Sometimes fine sand is used instead.

Isoplast DP

This kind of material is used to equalize the steam. It is made on the basis of glass fiber. There are several modifications: DHP-1.5 ... DHP-2.5.

Use of an isoplastic for protection of roofs

It is permissible to remove the material under consideration on absolutely any basis. It can be as concrete (high-rise buildings), and a crate made of wood or plywood. In the first case, the surface is pre-primed. Use this roofing material in any climatic regions of Russia.

In the event that the roof is covered for the first time, at least two layers of material should be laid. At the same time, as it was said before, an isoplastic "P" is spread on the bottom, "K" on top. If the roof has already been covered with some roll material, it is allowed to use only one layer - "K". Places of junctions (chimneys, skylights) and joints (valley) should be laid in several layers. In this case, it is possible to use as an isoplastic EPP 4, the technical characteristics of which make it an ideal option for this purpose, as well as EPG 5 or modifications of HPP.

Strips are laid with overlapping in both horizontal and vertical directions. On the pitched roof the material melts from the top down. At installation use a special roller for rolling strips. For the upper layer, an isoplastic EKP 4-5 should be used, the technical characteristics of which make it possible to arrange a very durable, absolutely watertight and repairable roof.

Correction of damaged coatings is as follows:

• On the site of the swelling the material is cut crosswise.
• Angles are bent and heated from below by a gas burner.
• Then they are put in place and tightly pressed.
• A patch is placed on top of the damaged area.

The rules for installing an isoplastic in the case of its use as a waterproofing material are the same. Surface before gluing should be carefully prepared, clearing of dirt and leveling.

As you can see, the isoplastic, the technical characteristics of which are presented above, - the material is very high-quality, reliable and durable. Even despite the rather high price, using it to cover the roofs is definitely worth it. Due to its durability and reliability, it will pay for itself very quickly.
