Requirements to sandwich panels

Selecting sandwich-panels for erection of enclosure designs of specific object, the following major criteria can be used:

- Conformity to heat-insulation regulatory requirements. Minimal admissible heat transmission resistance (Ro) of walls and coverings for buildings of various purpose and different climatic conditions regulated by Construction Codes and Regulations 11-3-79 Building heat engineering, 1998.

- Conformity to regulatory requirements to durability, stability of designs and fire safety.

Depending on the parameters listed above) the constructive elements varied in thickness, type of insulation (so in relative density) can be accepted.

Hygienic, sanitary and ecological requirements especially of special facilities (primarily, it concerns medical institutions, the enterprises of food-processing industry) are not less important.

ISOBUD sandwich-panels correspond to all parameters and  construction standards listed above and provide:

•    Safe construction.
•    Heat-insulation and impermeability.
•    Fire safety.
•    Sound insulation.
•    Quality and durability.
•    High speed of building.
•    Safe for health and environment.

Conformity of sandwich-panels to characteristics listed above is checked with tests and confirmed with certificates of the state certification bodies of Belarus, Russia and the Ukraine.

Choice of heat insulation material for sandwich panels.

Wide range choice of sandwich-panels with various characteristics (properties), offered at the market, is primarily defined in dependence of operational, thermal and geometrical characteristics of heat insulation materials.

Key factors, which influence on selection of heat insulation materials:

•    Service durability, endurance and the minimal risk of damage
•    Heat-insulation and strength characteristics of material;
•    Sizes of heat-insulation for individual type of building (to optimize heat transmission factor and energy savings);
•    Ecological and hygienic properties (it is important while selecting materials for construction of buildings in food branch).

Heat insulation characteristics.

Construction standards demand lower values of heat transmission factor of external covering, the most important point during selection of heat insulation materials is consistence of their thermal and hermetic characteristics.

Moisture resistance.

Protection of heat insulation core from moisture, which enhances thermal conductivity, is the greatest risk factor.

Dampening caused by condensation, leaking cladding or pipeline causes strong increase of thermal conductivity
Compression
Products with smaller durability and low assay of binding agent bear the risk of compression – for example, in the cases of flat roof application. This problem can be avoided with good designing.

Design of ISOBUD wall and roofing sandwich panels with various types of heat insulation cores provides optimum heat insulation characteristics. Reliable packing of panels protects from moisture penetration and mechanical damages during transportation, storage and installation.

Panels with invariable life cycle pass inspection at all stages, since the design, factory manufacture, packing and delivery to the customer, and installation, building operation and processing at the end of service life.
