Let’s start with the GLASS...

We use Cardinal® IG Glass Units in our windows. Check out Cardinal's Video Page for more information on the benefits of LoE2 glass, and to learn why Cardinal IG is the leader in the industry. Unlike some other window manufacturers, we leave the glass to the experts.

Our Glass System—A Major Advantage
All insulated glass will save energy. Parco’s system has the edge, however. This technologically advanced insulated glass spacer system utilizes a unique, U-shaped channel to separate glass panes and interrupt the natural flow of heat to cold. It also reduces the chill that can occur around the glass perimeter. This is standard on most products.

While some spacer systems use four separate pieces of aluminum joined together by corner keys, our warm-edge design is a continuous piece. The result is a stronger, more energy-efficient insulated glass unit. In addition, the warm-edge spacer’s unique ability to flex with glass expansion and contraction ensures a strong seal for the life of the window. In fact Cardinal’s superior IG construction translates into a 0.5% seal failure rate over twenty years - plainly the lowest in the industry.

LoE270 Glass for Higher Thermal Performance
For maximum energy efficiency specify optional LoE270 glass filled with argon gas which gives the center of glass R-value of 4.35 and offers protection from the sun’s damaging ultraviolet rays. LoE270 glass is up to 40% more energy efficient than other types of lowE glass—and up to 50% better than ordinary insulated glass. And since LoE270 also blocks more of the sun’s harmful ultraviolet rays, it will help protect furniture, carpet and drapes from fading while letting plants thrive.

Vinyl for Maintenance Freedom
All of our windows are constructed with rugged, maintenance-free uPVC (polyvinyl chloride). Unlike wood or metal windows that can stick when they swell or deteriorate from corrosion, pitting or rot, vinyl windows never will. Wash them with soap and water and they’ll look great year-after-year.

Because vinyl’s base color is solid throughout, you’ll never need to paint or stain these windows. The same properties that ensure vinyl’s maintenance freedom also allow window designs that are easy to operate and clean.

Built Tight to Keep Air Out
Air infiltration is a major cause of energy loss. Our sashes are double weatherstripped and double-hung and sliding windows feature full meeting rail interlocks. This method of construction creates a solid barrier to air and water. Parco casement windows are lined with two seals of specially designed weatherstripping which provides one of the lowest air infiltration rates in the industry. The low air infiltration rate means windows prevent drafts and keep you comfortable.

Why does this matter?
At Parco, we are sincerely concerned about your satisfaction. Our selection of only the best materials in our windows, combined with assembly by some of the most experienced people in the vinyl window industry, has yielded some of the best results ever. We prove it through independent testing at Architectural Testing, Inc. in New Brighton, MN.
