Bitumnyie rolled materials nevechnyi, but serve regularly

QUESTION: What name «a soft roof»?
The answer: as the "Soft" roof the traditional flat roof often is referred to. As a rule, it consists of a bearing plate, on which on a layer paroizolyatsii is laid teploizolyatsionnyiy a material (more often plates of mineral cotton wool), protected from effect of an atmospheric precipitation by a waterproofing carpet on a basis bitumosoderzhaschih rolled materials.

QUESTION: What should be a bas of a roof from rolled materials?
The answer: Rolled materials can supply water resistance even at zero biases. The limit up makes 45-50 ° because at bolshem a bias sticking together layers (mastics) under the influence of heat can flow down.

QUESTION: whether Have classification rolled materials?
The answer: Roofs from rolled materials happen bitumen (roofing material) and pitch (roofing felt and its derivatives). Also there are some basic methods of stacking of rolled materials according to which these covers are subdivided on:
  • Pasted on hot bitumen mastics.
  • Pasted on cold rezinobitumnyih, bitumno-polymeric both polymeric mastics and glues.
  • Naplavlyaemyie:
    — On the oxidised and modified bitumens;
    — In the hot (fire) method by means of gas torches;
    — Hot (bezognevyim) in the method by means of the equipment of infra-red radiation;
    — Cold (bezognevyim) in the method, i.e. dissolution utolschennogo a bitumen layer.
  • With a gluing layer when materials from the inside have a special sheeting (silikonovuyu a film or a paper) which needs to be removed before roll stacking on the grounded surface.
QUESTION: What dignities of rolled bitumen roofs?
The answer: They have low heat conductivity, have small weight, can be colour at the expense of a mineral crumb, vpressovannoy in a bitumen layer. Rolled materials are most traditional, accessible and cheap.

QUESTION: How correctly to be prepared for the system of a rolled roof?
The answer: the Rolled roof lay on the rigid and equal basis. For days prior to the beginning of works roofing material or roofing felt it is necessary to unroll, cut on pieces on length of a slope, having added 250 mm on bends through the fad and karniznuyu a board. Further shpatelem, a firm brush or by means of kerosene to clear the bottom party strewed by talc, and from lateral aspect for prikleyki mastic nakryiva the next sheet (polonka) to clear an edge in width of 100 mm.

QUESTION: whether It is possible to execute with the purposes of economy a soft roof to nonprofessionals – after all its system simply?
The answer: It only at first sight. Do not trust roof installation to casual people. Attempt to save on the project, quality of a material and payment of workers turns around additional expenditures. It concerns any type of roofing cover. Criteria for choice firms usual: availability of the licence, warranties, agreements with terms, desire to carry out preliminary research of designs and in writing to inform the customer on possible problems, readiness for intermediate checks and a high level of culture of dialogue.

QUESTION: In the USA and Canada bitumen roofs are considered till now very reliable. Why they proceed in Russia?
The answer: One of the reasons of small reliability of bitumen roofs is heterogeneity of a roofing carpet, weak adhesion (coupling) between material layers. Four layers of roofing material well stuck together by hot bitumen mastic are strong and reliable cover with the guaranteed tightness at the expense of overlapping of layers. Problems arise, if not it was possible to stick together well roofing material in "field" conditions. After all the technology of the system of roofs is difficult enough and requires application of coppers with the adjustable temperature established depending on mark of bitumen. Frequently heat of mastic does not suffice to "activate" a material, i.e. to heat up integumentary bitumen to temperature at which there is a good, qualitative pasting of layers. As a result non-uniform cover, vulnerable for a moisture, mechanical loads, operational loads is received. On a cold roofing material quite often rastreskivaetsya and in a roofing design starts to get a moisture. Therefore quickly enough cover becomes unfit for use. According to experts, in 1-2 years proceeds to 30 % of roofs, in 5 years – to 70 %, and in 7 years all roofs with cover from bitumen materials flow practically.

QUESTION: How to explain the term «artificial ageing of bitumen»?
The answer: Bitumen has low temperature constancy: more low +50°S. To lift its temperature constancy to comprehensible level, bitumen oxidise. Through nagretyiy bitumen is passed air. Thus also there is an artificial ageing of bitumen. Oxidation process "starts" process of the accelerated ageing of bitumen: at oxidation of a molecule of hydrocarbons "are torn", on the released chemical bonds oxygen molecules get.
In total some factories in Russia have oxidising installations and can oxidise bitumen independently, correctly leading up its properties to necessary parametres. Source: the Newspaper "Building" #27 (2004) heading «Stroyinform»

Nadezhnost above if the roof "breathes"
QUESTION: What is the "breathing" roofs?The answer: Unlike a habitual method of stacking of a roofing carpet (continuous prikleyki rolls to the basis), sometimes materials are expedient for stacking, using so-called partial prikleyku. Thereby conditions for occurrence of redundant pressure owing to formation of an air backlash between a roof and the basis are excluded. The roofs executed in such...
