Glass wool blanket and board

Gerui centrifugal glass wool is a kind of heat insulating material with thin and long fiber and low thermaI conductivity.With special structure.jt can encompass air welI so that the air cannot flow and thus convective heat transfer can be avoided.Meanwhile,it can also quickly reduce sound transmission,bringing good effect of sound absorption.Gerui centrifugal glass wool includes two major series,i.e.glass wool felt and glass wool board.

Gerui centrifugal glass wool felt has two categories,i.e.facing—free felt and compound facing felt.These products are widely used for workshops,warehouses,refrigerating chamber,gym,exhibition center,heat preservation shed for cultivation,steel structure buildings,various indoor entertainment places,and so on.

Gerui centrifugal glass wool board also has two categories,i.e.facing—free board and compound facing board.These board are manufactured by adding thermosetting bond into glass wool and then subjecting the glass wool to pressurized treatment and heated solidification.Compared with glass wool felt.qlass w board has better and stabler noise absorption performance.1 hese products are widely used in industry.exterior heat preservation system of residentiaI buildings,air conditioning and some other fields.
