Now it is used more and more, because sound insulation, insulation, excellent sealing performance has become the preferred product for energy saving. The calculation formula is as follows:
Total price = bridge-cutoff aluminum alloy unit price * Total square meter hardware suit * unit price open live fans * quantity of screens * unit price balcony angle * unit price
Price includes: the cost of beam is 180 yuan/meter, the cost of column, the cost of film, and the cost of waterproof adhesive is 10 yuan/meter, etc.
For example, Mr. Li has 10 square meters, want to be a beautiful 70 series ten seal, intend to open 3 windows, with imported hardware and movable screen, no balcony corner. The total price is calculated as follows:
Total price = 10 square meters * 558 yuan 3 sets of imported pendants * yuan 3 Fan * 350 3 detachable screen * 200 yuan = 8190 yuan. Including all expenses
This is the calculation formula. This is a very simple formula. As long as you own your own square meters, you can know exactly how much the sealed balcony costs.
