Single Hung Windows

Carefully engineered multiple hollow chambers within all Heartland windows, produce benefits not found in wood, aluminum or other vinyl windows. These chambers create layers of “dead” air, one of the most effective insulators available, providing you with a thermally efficient frame with superior resistance to heat transfer.

Intercept insulating glass technology not only retains its performance over the years, but offers superior thermal performance. Unlike conventional box spacers, the Intercept spacer uses a U-shape design that flexes instead of the sealant during temperature changes. This innovative design resists spacer movement and sealant failure, resulting in high resistance and improved seal longevity.

Low E (low emissivity) coated glass is an important component of all our windows and doors. This specially formulated glass coating keeps out the sun’s heat without affecting your view.

Low E specifies a microscopically thin, virtually invisible coating deposited on a glass surface. This coating limits radiant heat flow between window panes by reflecting heat into your home during cold weather, and back to the outdoors during warm weather.

Even more, it blocks 95% of the sun’s damaging ultraviolet rays to protect your furniture, carpets, curtains and wall coverings from fading.

Neat naturally clean glass harnesses the power of the sun’s UV rays to loosen dirt so water can rinse it away, leaving windows virtually spotless.

Using our patented double-sputtering process, we apply an invisible, durable and permanent coating of titanium dioxide and silicon dioxide. The silicon dioxide makes the glass exceptionally smooth so that water disperses evenly, sheets off, and evaporates quickly. The titanium dioxide reacts chemically with the sun’s UV rays causing materials on the glass to decompose.

No activation is required. Windows clean easier and stay cleaner longer.
