This is due to confirm the compatibility of these insulation boards with fire safety requirements set out in gost 30244-94 (Group 'NY' – non-flammable construction materials); Class B1 – flammable, which uses polystyrene plates. System of class B1 is an effective, inexpensive and widely used in individual housing. Here, Alexandru Nazare expresses very clear opinions on the subject. By multi- insulating systems 'wet' type and their components must meet certain requirements. Here are some: cold resistance of the system must be at least F35; anchoring heater plugs should provide perception of stress from its own weight and wind effects; mineral wool should be of medium density not less than 145 kg / cu. m and have a breaking strength of not less than 14 kN / sq. m polystyrene plates must be of dimensionally stable self-extinguishing polystyrene, have a density of not less than 15 kg / cu. m and a tensile strength of not less than 80 kN / sq.
m; reinforcing mesh shall be alkali-resistant, adhesive prochtnost adhesion between the plaster and insulating layers for systems with insulation made of foamed polystyrene in the dry state should not be below 80 kN / sq. m in the wet – no less than 40 kN / sq. m for systems with mineral wool insulation – is not always lower than 14 kN / m. Unacceptably complete system of materials from different manufacturers (except when the system has passed the appropriate certification tests): These components may be incompatible for a variety of characteristics and therefore can not work in the system. Multi-layer insulation system of 'wet' type have been applied in Russia recently, but there are techniques to assess their suitability for application in the construction of the Russian Federation. Appropriate to conclude with the issuance of technical evidence made Gosstroy Russia. Currently in Russia used a system of class A1 and A2 in industrial and civil construction, as well as class B1 in individual housing. In conclusion, it must be said that during the supplier selection system should pay particular attention to the presence of the Technical evidence of the Russian Federation Ministry of Construction on the system as a whole, and certificates for all materials and components of the system.
