At1.03 w/m.k., this is also called thermal conductivity, which represents the physical quantity of thermal conductivity of a material. Moreover, the thermal conductivity of materials is also determined by changes in composition, physical structure, state, temperature and pressure. The source of thermal conductivity is Fourier law.

How to choose the right glass

1, look at the brand.

Generally speaking, glass products have registered trademarks of relevant units and reasonable price positioning, which is also a perfect after-sales system, so as to make consumers feel more at ease.
