DESCRIPTION
:
Insuwrap PVC water tank internal liner
1500 LNTR is a calendered high polymer waterproofing
membrane, (thickness 1.50mm) reinforced with polyester mesh, not
compatible with bitumen, manufactured to the highest
International standards offering high physical properties and
long term durability. Insuwrap 1500 LNTR is manufactured using
the best raw materials produced by SABIC.
