Among various options for wood substitutes doors, technically Fiberglass door Shutter and frame are much superior alternative as compared to any of the wood/ mild steel substitute material like PVC, UPVC, WPVC etc. Door Shutters and frame in PVC & UPVC have emerged as second alternative to wooden doors. As PVC material can be recycled, most of the manufacturers have stopped using virgin material as a result the quality of PVC Door & Frame has deteriorated and the life and durability of the product is very poor. Among the various materials and options available for manufacturing of PVC Door Shutter & Frame, 5 mm thick PVC foam sheets are relatively durable for manufacturing of the same. Product Specification as per CPWD, DSR/Railways are given below.
