Perfect Heat Preservation Insulation

The high density and closed structure of selected raw material has the ability of low thermal conductivity and stable temperature and has an isolation effect of hot and cold medium.

Good Flame Retardant Properties

When burned by fire, the insulation material do not melt and resulting in low smoke and do not make the flame spread which can guarantee the using safety; the material is determined as nonflammable material and the range of Using temperature is from -50℃ to 110℃.

Eco-Friendly Material

The environmental friendly raw material has no stimulation and pollution, no hazard to health and environment. Moreover, it can avoid the mold growth and mouse biting; The material has the effection of corrosion-resistant, acid and alkali, it can increase the life of using.

Easy to Install, Easy to Use

It is convenient to install due to it is not need to install other auxiliary layer and it is just cutting and conglutinating. It will save the manual work greatly.

Insulation Application

Frequently Asked Questions
