Who will explain the advantages and disadvantages of aluminum veneer for curtain wall?

Advantages 1. Thermal insulation function; The above functional requirements are common in engineering decoration, but traditional materials are difficult to meet at one time. The aluminum veneer curtain wall can meet the design requirements of sound insulation and heat preservation by punching holes and adding sound-absorbing mineral wool. Tested by the national authoritative organization, the thermal insulation efficiency of the product in practical application, the temperature difference between ordinary installations is 7 degrees, while the summer in the south is hot and the winter in the north is cold, so this building material is one of the best decorative materials. With excellent thermal insulation function, it can be used in balconies, sun rooms, top floors of villas, stoves and other places for a long time besides wall installation. It belongs to energy-saving and environment-friendly decorative materials advocated by the state.

Advantage 2. Good sound insulation effect: the sound insulation of this product is as high as 29-32 decibels, which is equivalent to the sound insulation effect of solid brick walls. It can solve the problem of noise pollution when used in bedrooms, study rooms and other rest places, while it can solve the problem of loud sewer noise when installed in toilets. In infrastructure projects, noise barriers are often used in airports and high-speed rail residential areas, which effectively solve the noise pollution caused by traffic noise to residents.

Advantage 3. Fire protection function: With the continuous improvement of the government's awareness of fire safety in public places and related laws and regulations, it is also a common headache for construction contractors to classify the burning performance of building materials. It is difficult for general materials to meet the different characteristics of safety, environmental protection, beauty and durability, while aluminum veneer curtain wall is made of metal and is one of the natural fire-proof building materials. Tested by the fire department, the fireproof grade of aluminum veneer is as high as A2 and the melting point is as high as 660 degrees, so it is one of the excellent fireproof building materials. In many projects, aluminum veneers and various aluminum decorative building materials can be directly put into construction without authorization of combustion performance grade appraisal.
