What is the fire endurance of fireproof glass cotton?
Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass?silk λ=0.043W/m2K. good fireproof?performance, it's fire-resistant capacity is more than 1000 ℃.
The highest temperature of fireproofing glass wool can be above 200 degrees, so it can be used for a long time,it's difficult to judge the special usage time, but its usually about 3 months and 8 hours every day.
of course,A level is better. A-class is non-combustible, class B is fire retardant, rock wool fire resistance is 800 ℃, glass wool fire resistance is 450 ℃ , class B has a relatively better thermal insulation effect, hope it can solve your doubts.
