Roofing board is the basis for the manufacture of tar and bitumen roofing and waterproofing materials. Modern industry produces cardboard, having a width of 1 m, and the total area of ​​the roll reaches 20-40 m2.Weight 1m2 can be equal to 250-420 g.

Such uncoated lining material is used for the lower layers of roofing carpet, made of roofing coating. Roofing parchment is made of cardboard, impregnating with oil bitumen. There are such brands of this material as P-300 and P-350.The implementation of glassine is carried out by rolls of 20-40 m2, having a mass of 13-30 kg.

Manufacturing of roofing felt is possible from roofing cardboard by means of double impregnation with tar products. This roll material is produced uncoated( tol-skin) and with sandy and coarse-grained powder. The purpose of roofing roofing - the device of the upper and lower layers of the roofing carpet. Waterproofing roofing is used for insulation of various elements of the structure.

Unshielded tole or tole-leather is intended for the same purposes as parchment. In a number of cases, it is used to arrange a lower layer of carpet from roofing material with sandy sprinkling.

Double-sided sand tar used for the installation of both the upper and lower layers of the roofing carpet. There are two brands of this material, namely TKP-350 and TKP-400( the weight of the roll is 23-25 ​​kg, its area is 15 m2).

On the front side, it has a protective layer made of coarse-grained powder, and on the back - from a pulverized mineral. Such material is used for the top layer of the roofing carpet.

In hydrizolation roofing roof with cover film of impregnating composition on the front side there is a protective layer with fine-grained mineral powder. The lower layer of this material is covered with a pulverulent or fine-grained powder. Such stamps as TG-300 and TT-350 are produced. Such roofing is intended for vapor barrier and waterproofing of structures of buildings. It can also be used for the installation of the lower layer of the roofing carpet.

Roofing rolls should be stored for a maximum of one year from the date of release in an upright position.

Rolled materials, depending on the type of binder, can be divided into tar, bitumen and polymer. The most common roll material for roofing is roofing material.

Kinds of roofing material

Roofing ruberoid with coarse-grained sprinkling is used for top and bottom layers of roofing carpet and waterproofing device. The weight of the roll is 25-27 kg, and its area is 10 m. It can be laid on both hot and cold mastic. Two brands of such material are produced, namely RCM-350B and RCM-350V.

Roofing roofing material with a dusty powder on the underside and coarse-grained - with the front one intended for flooring of the top layer of the roofing carpet. Modern industry produces four brands of such material, namely RKK-400A, RKK-500A, RKK-400B, RKK-400V( weight of the roll -24-29 kg, its area - 7.5 m2).

Roofing ruberoid with scaly powder is produced under such brands as RKhC-350B and RKhC-350V: one-sided( weight of a roll is 20-28 kg, its length is 20 m), two-sided( weight of a roll is 26-32 kg, its length is -20 m).

Ruberoid with one-sided sprinkling is applied to hot mastic, with double-sided - both hot and cold.

lining with fine-grained powder is one-sided( weight of roll is 20-26 kg, its length is 20 m) and bilateral( weight of the roll is 24-39 kg, its length is 20 m).This kind of roofing material is used for the lower layer of roofing carpet, as well as waterproofing structures. On sale, it is three brands, namely RPM-300A, RPM-300B, RPM-300V.

A lining felt with a dusty powder has the same function as the previous one. To construction organizations and the population it is sold under such brands as РПП-350Б and РПП-350В( weight of a roll - 27-30 kg, its area - 15 m2).Another three existing brands of ruberoid with a dusty powder are used only for the lower layer of the roofing carpet and are not intended for waterproofing. Such brands are РПП-300А, РПП-ЗООБ, РПП-ЗООВ( weight of a roll - 22-27 kg, its area - 15 m).

Steklorrueroid belongs to the group of roll roofing and waterproofing materials. Bitumen is applied not on cardboard, but on a fiberglass substrate on both sides. In construction works, such brands of glass-ruberoid as C-RM( for waterproofing and lower layers of the roof), C-RC and C-RF( for the upper layer of roofing carpet) are used. The weight of the roll of such material is 23-29 kg, the area is 10 m2, the thickness is 2.5 mm, and the width is 960 and 1000 mm.

Each grade of ruberoid is designated by the appropriate brand, for example RM-400.The figure here indicates the mass in grams per 1 m2 of the cardboard-base, and the value of the letter "M" is "fine-grained".

To paste a roofing material, bituminous mastics of different brands are used, which depend on their heat resistance.

In addition to the above brands, the modern industry produces a ruberoid with an adhesive layer of mastic applied to it. Before use in construction work, this layer is pre-softened with a solvent specified in the enclosed instruction, or melted with hot air.
