It is used where the insulation layer must stay continuous while workers still need access to brackets, covers, labels, or future inspection points. The product should be matched with 30-60 mm common thickness; facing and density by report; then the facing and fixing method are confirmed so the finished surface is not damaged by repeated trimming.

For ceiling or duct work, the material should be matched with bracket spacing so the surface does not sag after fixing.

 
03
 

For narrow rooms, prepare shorter pieces or smaller rolls when long pieces cannot be moved through the site safely.
