A roll of ruberoid, whose width can be equal to 1000, 1025, 1050 mm, has a weight varying from 26 to 30 kg. This parameter can vary depending on the brand. In the production process, specifications are used that do not allow a deviation in width greater than 5 mm. Builders are also interested in how many meters are contained in a roll of this waterproofing material before purchasing the described material. Thus, if the material is coarse-grained, then the length of the web in one roll is 10 m, while the dust coating is limited in the length of the roll - 15 m.

Before you buy a roll of ruberoid, its size you should study. This indicator sometimes depends on the brand of the material.

If you need roofing material to work, then you need to take one that has a thickness of 3-5 mm, whereas in the case of litter material, this figure is 2.5 mm or more.

Features of composition

Cardboard is the basis of absolutely all kinds of ruberoid, but it can differ in density. If we are talking about roofing waterproofing, then it is much higher and is approximately 350-400 g / m ² . To ensure better adhesion to refractory bitumen, cardboard is treated with a low-melting bitumen. This, among other things, increases the moisture resistance of this layer.

It should also be noted that the top layer of the material has a coating in the form of a difficult to melt bitumen, which is mixed during the manufacturing process with plasticizing mineral additives. The finishing layer for different grades of material can be made from talcum, which is a dust-like powder. As an alternative, large-fraction sand is sometimes used, which is a coarse-grained powder.

Roll ruberoid, the size of which is specified above and is important for the master, has a lower covering layer, which contains the same difficult to melt bitumen, which has additives. The sprinkling of the bottom layer of any brand consists of talc and mica, this composition prevents the coil layers from sticking together during storage.

Marks of roofing material

Sprinkle can also be scaly. If it is a one-sided roll, the weight will be 20-28 kg, and the length will be 20 m.

As for double-sided material, its weight in the roll will be 26-32 kg. The length will remain the same. If you decide to use a one-sided roll, then its installation can be done only on hot mastic, while the double-sided must be laid over cold and hot mastic.

It can be used only for waterproofing, as talc is used as the top layer. It can also be used in the role of the lower layer in the arrangement of the roof. Its coating weight is 800 g / m.

Characteristics of roofing felt РПП-300

This brand is often considered identical to the previous one. This material is used for the mentioned purposes, but this kind of roofing material has not so impressive characteristics. The breaking force is 22, and not 26 kgf. However, the weight of such a roll will be less, sometimes it is important for the arrangement of the roof. At 1 m ² such material will have an effect in 500 g.

Characteristics of roofing felt of grade РПП-200

The ruberoid, the GOST of which is denoted by the figures 10923-93, can be produced under the marking РПП-200. It is used in the arrangement of the roof, as well as in the basement. It is based on cardboard, which is covered with talc in both sides, as well as with petroleum bitumen. Due to the application texture, this kind of roofing paper has excellent flexibility when compared with other similar materials.

Characteristics of RM-350

The width of the roofing felt is already known to you, now you can pay attention to the fact that there is a brand RM-350. This material does not hold heat as well as others. The water absorption coefficient is 40 g / m. But the cover layer is 1600 g.
