3,Curtain wall with rock-wool board
Introduction
Curtain wall with rock-wool board is a series of rock-wool products specially for fire prevention and heat insulation of curtain wall constructions which is made of slender fibers and thermosetting resin.
Its melting point reaches 1000 degrees and has excellent thermal stability. It will not have obvious deformation and can effectively prevent and delay the spread of fire even if the temperature is rising when fire occurs.
In addition, its ability to resist high temperature contraction is for superior to other products made of ordinary mineral wool. Curtain wall with rock-wool board can also be covered with aluminum foil and glass fabric.
Features and Application
,Fire Resistance
Curtain wall with rock-wool board is incombustible material which can resist high temperature contraction with the melting point of 1000 degrees. It can meet the requirements of fire resistance limit of 2 hours in the fire resistance test.
,Smoke Prevention
Curtain wall with rock-wool board is fireproof and can not produce smoke in the fire which will not do harm to human bodies.
,Thermal Insulation
It has excellent thermal insulation performance which can effectively reduce the energy consumption of air condition to maintain the building environment of comfort and stability.
,Sound Absorption
It can obviously improve the sound insulation performance of curtain wall.
,Durable in Use
Curtain wall with rock-wool board uses the advanced production technology, according to the strict quality standards and production control process, and thus the service life of the product is long.
