This product is a patent worldwide by Sun Asia Enterprise Co., Ltd. created using high technology and adopts global unified quality to ensure product stability.

A layer of anti-UV coating on the surface is applied during the process of co-extrusion, which prolongs the lifespan of the sheet. The purpose of the anti-UV coating is to prevent ultraviolet from shining through, which could cause discoloration and brittleness.

Centre structure adopts slant angle which enables gentle morning sunlight to shine through unlike traditional twinwall which adopts vertical angle that blocks the sunlight totally.

The thermal insulation ability of Shutter Twinwall is better due to its slant structure which absorbs heat better compared to traditional hollow sheets and other thermal insulation sheets in the market.

The weight is lighter compared to glass. The weight of a 6mm thick glass is 16kg per square meter unlike the weight of Shutter Twinwall which is 1.74kg per square meter.

The appearance of the sheets offers higher aesthetic value than ordinary twinwall sheets. Some outdoor application options are skylight and roofing while indoor application options are partitions and blinds.
