California modern grill design sound proof French casement windows with decorative

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.

Our design team can customize our windows to your unique project requirements.  Window dimensions, mullions and muntin are available in unlimited configurations.  We can tailor our products for specific applications such as high security, hurricane resistance, extreme sound transmission reduction, UV protection, etc.  We will work off your drawings or create our own based on your requirements.  After finalizing the order, our design team will prepare a final drawing for client review and acceptance before manufacture. 

We back up our products with a 10 year warranty for your peace of mind.Contact a Doorwin sales representative to experience what sets us apart from the rest.
