Window Replacement Contractors

RIHI realizes replacing windows in your home is extremely significant towards improving its beauty and efficiency. Making the right window choice is important.

You want to be sure the windows you select are:

This made our choice of developing the PROTEC Replacement Windows by RIHI such an easy decision.

Vinyl windows represent the best choice to compliment your home’s beauty thanks to recent breakthroughs in engineering and designs. Combined with the latest technology in insulated glass, they meet or exceed Energy Star requirements predicted for the next decade.

Don’t be fooled! Replacement windows—regardless of how similar they may appear—are not all created equal. Many run-of-the-mill replacement windows are designed with low cost in mind as opposed to value. Windows constructed simply from wood, vinyl, or aluminum will leave your home vulnerable to frigid winter air, which will saddle you with astronomical heating costs.

PROTEC windows, on the other hand, feature a proprietary mix of specialty polymer and acrylic resigns. This composite construction creates a solid core insulation system far superior to other vinyl replacement windows that have hollow walls. When shopping for windows you must be mindful of strength and durability, both of which materials such as wood, vinyl, and aluminum simply cannot provide. Don’t short change yourself and settle for just any replacement window. Choose PROTEC!

RIHI also understands the need for homeowners to express their own unique style when it comes to improving their homes. Curb appeal concerns many people, and for good reason. PROTEC replacement windows embody the best option in this regard, enabling you the freedom to select from different models, styles and options. Each room in your home will have the individual interior look you desire while also offering you the beautiful appeal you deserve. If you want to leave all neighborhood passersby envious of your home then PROTEC is your obvious choice!
