The setting of building exterior wall insulation and fire isolation belts is a very important step in exterior wall insulation. Below we will briefly introduce several common fire isolation belts in building exterior wall insulation.
Rock wool fireproof isolation belt
“Rock wool board” is mainly made of hydrophobic rock wool board produced by the pendulum method as the thermal insulation layer material, and is bonded and nailed to the base layer using a bonding and nailing process. The walls are connected and fixed, and are composed of a plaster layer composed of plaster mortar and reinforced fiberglass mesh, as well as a decorative mortar facing layer or paint. It is a Class A non-combustible building energy-saving insulation system. The rock wool board exterior wall insulation system has the advantages of low thermal conductivity, good air permeability, and high combustion performance. It can be used in energy-saving insulation projects for newly built, expanded, and renovated residential buildings and public building exterior walls, including exterior wall insulation, Fire isolation tape for non-transparent curtain wall insulation and EPS external insulation systems.
Phenolic foam fireproof isolation tape
Phenolic beads are pre-foamed by heating and then heated and formed in a mold. It is a phenolic foam plastic with a closed cell structure. The use temperature does not exceed 120°C. Plate. It has the characteristics of: good fire retardant performance, refractory to fire; no shrinkage, no deformation, no dripping, no smoke, and non-toxic.
Foamed cement (foam concrete) fire isolation zone
It is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam and cement slurry. Then it is cast-in-place or molded through the pumping system of the foaming machine. After natural curing, it is formed into a new type of lightweight insulation material containing a large number of closed pores. Since the raw materials are all cement, they can also be used as fireproof isolation belts.
The commonly used fire isolation belts in building exterior wall insulation are mainly rock wool, phenolic foam and foamed cement. </p
