Glass Options
We provide various glazing options to suit different project needs, balancing performance, aesthetics, and budget.

Double Glazing
Double glazing can withstand greater wind pressure in high-rise apartment buildings, ensuring safety and stability while effectively reducing external noise for a quiet living environment.

Triple Glazing
Triple glazing is widely used in buildings located in cold or noisy environments. Compared to double glazing, it offers better insulation, energy efficiency, and soundproofing. It helps reduce heating and cooling costs and creates a quieter, more comfortable indoor space.

Our hardware system ensures smooth operation, long-lasting durability, and a high level of security, perfectly matching the overall performance of the window and door system.
