When you’re researching home window replacement, it’s likely that you’ll come across the name Vanguard. That’s because Vanguard windows are known throughout the industry for their high quality and performance.  Sunrise Windows is the maker of Vanguard windows and they have been recognized as an industry leader for design, innovation, and craftsmanship. 

Lifetime Warranty

Vanguard windows are hand-crafted with superior materials to provide exceptional durability. For additional peace of mind, all Vanguard windows also come with a Total Care lifetime, non-prorated, transferable warranty. This warranty package covers any material defects and accidental glass breakage for as long as you live in your home. 

Unique Features

If you’re questioning whether or not there really could be that much difference among window brands, the answer is — there is! Vanguard windows have several features that make them rank high in construction and durability. For instance, they are made with FiberCore® technology. Fiber Core is a material that increases the strength of windows — something that’s incredibly important for withstanding the cold and gusty Colorado and Wyoming winters.

Besides structural integrity, the next key feature of quality windows is insulation. That’s why Vanguard uses an UltraCore® insulated window system. UltraCore uses expanding polyurethane insulation foam to fill spaces and improve thermal insulation. Even on the chilliest winter nights, your family will stay warm and comfortable inside. 

Finally, the SecureSeal™ rail system and WindBlock™ weather stripping that’s standard in all Vanguard windows are two more components of these superior windows that will ensure your windows withstand the elements and provide the ultimate barrier to wind. 

Customizable Options

If you think that all windows are the same, then you haven’t explored the options available with Vanguard windows! From different colors and styles of finishes, frames, and hardware to decorative glass and grids, you’ll find the perfect windows to complement your home and suit your personal style. 

Vanguard windows also come with a variety of convenient options such as between-the-glass blinds, self-cleaning glass, and noise reduction glass. Pick and choose the options that are right for you to provide the ultimate in functionality and style to your home.
