Features of the RCC RCC

Despite the fact that in the construction market today there is a wide selection and a range of new and modern rolled materials for the roofing arrangement, the consumer is still most often preferred to the old good runner, the quality and reliability of which is tested for years. It is characterized by a wide range of applications, it happens roofing and waterproofing.

In this article we will describe in detail about the RKK type runner. We define the scope of application, features and technical parameters of this type of roofing material.

What it is?

The process of production of the runneroid from the beginning and to the end is governed by the regulatory document, namely GOST 10923-93 “The brand of roofing regurgids. Technical specifications”. Absolutely each Roll Ruberoid, which comes from the production conveyor, according to regulatory acts must have labeling. Marking is a letter and digital abbreviation, which carries complete information about the material.

Often you can meet the RCC marking. Here is the decryption of this abbreviation:

  • P – type of material, rubberoid;
  • To – appointment, roofing;
  • K – type of impregnation, coarse-grained.

Consequently, RPC RPK is a material that is intended exclusively for the roof coating device and has a coarse-grained impregnation.

Roofing RCC roofing roof drive, in addition to letters, has also digital values ​​in the abbreviation, which denote the base density. It is the basis of its cardboard, and the numbers denote the density of this material – the higher it is, the better and more reliable than the rolled coating.

RKK has a number of benefits and features, including:

  • High waterproofing properties;
  • resistance to mechanical exposure, ultraviolet, temperature regimen;
  • long service life;
  • Price availability.

Technical characteristics of marks

According to GOST 10923-93, RKK referenced can be made in several varieties.

Let’s look at the most popular and frequently used rolled roofing material stamps with coarse impregnation.

  • RKK 350B. This is one of the most frequently used material stamps. Most often used as the top layer of roof covering. The main raw material in the process of its production is a dense cardboard, which is impregnated with a low-melting bitumen. Top layer RKK 350B – coarse rugs from rocky crumbs.
  • RKK 400. This is very reliable and durable material. At the heart – high-quality bitumen and dense cardboard, which makes it possible to apply it not only as roofing material, but also for waterproofing works.
  • RKK 420A and RKK 420b. These are the rolled materials of the highest sample. Use them as a finishing layer of roofing. Made a web made of very dense cardboard, thanks to which the life of the data of the brands is doubled and is 10 years. These types of rubberoid are resistant to wear, mechanical exposure, various weather conditions. They have excellent waterproofing properties. The letter “A” and “B” after the figure denotes the brand of roofing cardboard, the coefficient of absorption and the time of its impregnation. The letter “A” at the end of the abbreviation means that the coefficient of cardboard absorption is 145%, and the impregnation time is 50 seconds. The letter “B” is assigned to the rubberoid, which is characterized by the impregnation time of 55 seconds and the coefficient of absorption – from 135%.

Scope of application

Ruberoid is the perfect building material for the roof. It is reliable, has excellent properties and characteristics, and stands, in comparison with other materials for coating, inexpensive. Although it is intended for the roof, it is most often used as the finish layer, it can also be used for waterproofing – both roofs and foundations. High physico-technical parameters of the material, namely the thick and durable cardboard and the presence of coarse impregnation, contribute to.

But, whatever it was, still experts recommend using the material solely by appointment.

As a lining material, the RKK RKK is not recommended.
