Doorwin is positioned to offer the finest value in quality wood aluminum windows.  We seek to make durable, energy efficient and beautiful products accessible to all budgets.  We strive to provide the best customer service experience with a dedicated design and engineering team for custom projects and a talented sales team that responds quickly to inquiries. 

Our energy efficient integrated glazing units (IGU) feature triple-pane glass, warm-edge spacers, argon gas fill, Low-E coatings and fully tempered glass.  Different IGUs are available to meet the needs of different climates. 

For all windows and doors exported to North America, we provide fully heat-treated, tempered glass as standard.  This provides extreme impact resistance to prevent glass breakage, reducing warranty claims.  When broken, tempered glass uniformly shatters into small pieces for safety. Our standard glazing for the North American market is SGCC (Safety Glazing Certification Council and IGCC (Insulating Glass Certification Council) certified for performance and safety.
