Product Introduction

IW-GS glass wool slab is placed in the glass of meltdown appearance proceed the fiber turn and spray the resin of solid that draw the hot silk wadding form material,then turn through hot solid the deep processing handles and can also make into the series and various  products.IW-GS  Glass  wool  slab  is  processed  by putting  the  thermosetting binder  into  the   glass  wool,by   pressing  and  heating,and  then,by curing.They  are widely   used  for   insulation   ,ventilation   and   the   adjustment  of  air-conditioner in commercial   industry   and   residential   construction.Meanwhile,it   has   the   effect   of energy-saving insulation,sound controlling and improving the indoor air quality.IW-GS glass wool slab is rigid but flexible product and no corrosion to the tank or pipe surface, easy to  install  and  fixed with wire  or banding  and  clip,then  covered  by  galvanized sheet or aluminum sheet to protect the glass wool from UV,weathering influence.
