Building costs of typical individual house is about 40% cheaper than another popular in eu systems;
Small costs of investment, production and working power the execution of buildings in system r;
Costs of air conditioning for typical house is about 5 times cheaper than another popular in eu systems;
Costs of heating for typical house is about 5 times cheaper than another popular in eu building systems;
System r possesses indispensable certificates and it fulfils all valid in eu building norms:
- stamina norms
- resistance on moisture
- protecting before noise
- protecting before fire
- hygienic norms
- norm of waste of energy
- large range of recycling
Coefficient of heat infiltration “u” for 30 cm of wall is ca. U = 0, 20 w/m2k and can be more reduced easily yet;
Heat energy consumption for typical individual house is ca. 42, 50 kwh/m2 and can be more reduced easily yet;
System consists from 17 basic building elements;
Lateral surface of one typical structural element: 0, 18 m2
Consumption structural typical elements per unit: 5, 5 elements/m2
The joining the elements follows of thin-layer plaster glue.
Basic materials to production small block in system r:
- plaster
- water
- expanded polystyrene, eps
