The prices in the calculator are informative, based on estimation and include the VAT!
You can read more about the required values settled in 7/2006 TNM regulation in the article Mit jelent az A kategóriás családi ház? , in the following illustration we show You that how many the heat transfer coefficient of the walling should be in the different categories of the regulation (only if the building engineering installations are compatible with the quality of architectural solutions of the building). It is known that in an excellent building, the building engineering can be crappy and the opposite. Therefore, the values in the calculator are just a point of reference.
