1 -Sound elimination between floors 1. Nowadays in Georgia sound insulation between floors are made according to USSR standards, and traditional design is of the following type

2 2. Our preposition for sound insulation among floors

3 Design used by one of our customers for sound insulation, also in case of fire it will protect communication infrastructure in below floor Ceiling 3. With the offered design sound insulation per 1 m² is much cheaper Note: In sound recording studios and similar type of institutions usage of 2 layers of the basalt fiber is recommended, that is sharply cheaper than other sound insulation possibilities. Moreover basalt fiber protects electrical wiring in case of fire. Price Cost GEL/m² Work m² Sum GEL/m² Basalt matm² 7,57,5––7,5 Pumicem³ 6,00,1 m³/m²6012

4 4. a) It is exceptionally effective for sound isolation in office areas and to create fire protection for communication networks. b) Also in construction, builder gains approximately 10 cm per floor, as the usage of floor buckle and pumice is not needed. c) It is able to use foam plastic or glass-wool between gypsum cardboard and between floor steel concrete, but in this case sound absorption effect is lower and because of the difficult work that should be conducted the installation costs rise (packing glass-wool into cellophane or fragility of foam plastic when fasting on ceiling).
