Product performance
Product features: small window opening arc plate PVC material, outer frame ABS, side frame PVC, thermal insulation cotton: high thermal insulation EVA, bracket 1.2mm thick 304 stainless steel, pin, bolt 304 stainless steel material ~ anti-aging, anti-corrosion, airtight performance Good features~ Compared with the brackets used by other manufacturers, some are 201, some are 304 with a wall thickness of 0.8mm, and the insulation material is sponge. The price of the four sponges above the small window is not as high as the price of one piece of EVA, and the sponge absorbs water. , In winter, it does not have a thermal insulation effect, and after absorbing water, the small window itself weighs a lot, causing the ceiling to sag.
