The curtain wall process installation is complicated, and the construction period is long

The integrated structure of thermal insulation layer of the insulation decorative board has formed the factory, which has reduced the construction link, which makes the construction very convenient.

1. System wet adhesion process construction process

The construction period of the same project was shortened by more than 50%compared with the construction period of the stone curtain wall, which was shortened by more than 30%compared with the traditional thin plastering system construction period, saving time and manual management fee. The construction impact is small, especially the existing building transformation, which can effectively minimize the impact of users’ work and life.

2. The construction of wet sticky method has low requirements for the grassroots level,

It is not affected by the weather and grassroots humidity, the new bonding technology, the wet and curing reaction bonding of the grass -roots level and the special polymer polymer of the wall, the reaction of completely wet and solidifying into a new bonding layer, the bonding strength Increased the pressure of concrete compression in the grassroots level, and there was no hidden water hazard in the middle.

Advantage 4: High economy

Based on the maintenance cost of 20 years, compare the comprehensive cost costs of each solution. Compared with the outer wall insulation system: the cost of aluminum -plastic board crafts is more than 40%higher; the price of stone dry hanging process is more than 60%higher; thin plastering has the advantages of construction costs, but the maintenance cost of the exterior wall paint for 5 years is considered. Under the premise, the total cost is about 30%higher.

Therefore, compared with other processes, the insulation decorative composite board has a high cost -effective advantage.

Note: The price in the chart is estimated, there are differences in various places;
