GONHO Aluminum heavy duty thermal break energy efficiency outdoor multi-slide door

Multi-slide sliding doors have three or more moving panels arranged in a row that slide open easily and intuitively, stacked side-by-side near the edge of the frame. When closed, these expanses of floor-to-ceiling glass create a spacious panorama that blurs the lines between the indoor and outdoor worlds.

Our sliding doors are made of double-layer or triple-layer tempered glass, which makes them have good insulation function in both summer and winter. During the summer, it preserves the cool air in the home and prevents heat from entering. It does the opposite during colder seasons. Of course, we can also use coated LOW-E glass to further improve energy efficiency and reduce UV ray exposure. Our sliding doors can also reduce frost and condensation on the glass.
