Glass Options and Energy Efficiency

When it comes to glass options, both brands offer double and triple pane windows, but the similarities end there.

SI Windows provides standard double and some triple pane options, catering to conventional needs for insulation and energy efficiency.

Milgard, however, elevates this with advanced triple pane options featuring SmartSun™ technology. This innovation not only ensures superior insulation but also blocks harmful UV rays, thereby protecting your interiors and reducing energy costs.

This technological edge places Milgard Windows in a league of its own for energy-efficient home solutions.

Exterior Color Choices and Customization

The exterior color of windows plays a crucial role in defining the overall look of a house.

This option allows homeowners to match their windows precisely with their exterior décor, providing an opportunity for personalization and creative expression.

Warranty and After-Sales Service

Warranty terms often reflect a manufacturer’s confidence in their product.

SI Windows provides a limited lifetime warranty on vinyl and a 20-year warranty on glass, indicating a commitment to quality and customer satisfaction.

Milgard Windows, however, goes a step further by offering a full lifetime warranty on materials and workmanship, alongside a 10-year warranty on glass.

This comprehensive coverage demonstrates Milgard’s confidence in its products and dedication to customer service.

Important Note: The choice between SI Windows vs Milgard should be influenced by specific needs such as budget constraints, aesthetic preferences, and energy efficiency requirements. Each brand has its strengths, and the right choice varies depending on individual homeowner needs and preferences.
