Windows and Doors are all about connecting the outside environment with the interior of homes and buildings. Primarily, they allow daylight to shine in, open to access fresh air, and, in the case of doors, provide easy passage between the two spaces.

Given these basic functions, quality windows and doors must be designed and manufactured in a way that maximizes the positive aspects of these functions while minimizing any undesirable consequences.

What should windows and doors provide?
• A great view from your home or building
• Let in sunlight to improve the quality and function of the living environment
• Let in fresh air when desired
• Seal out air drafts
• Add Beauty to the home or building structure
• Access in and out of the home
• Protect the home from the weather
• Protect the product from the weather
• Protect the home interior and furnishings from UV damage
• Promote Energy Efficiency
• Reduce Thermal Transfer (hot or cold) to keep the interior comfortable
• Long Lasting product life and performance

Sun attempts to address these functions while adding a design aesthetic that brings beauty to the structure.
