Energy-Efficiency Back to Windows
According to the U.S. Department of Energy and H.U.D.
- 70% of your heating dollars, and
- 46% of your air-conditioning dollars
are lost through windows and doors
Independent tests prove UniFrame windows perform significantly better than the industry standard for vinyl insulating glass windows and much better than many wood or vinyl brands. That’s because UniFrame windows feature the very best in thermal efficiency and technology, including:
Patented* R-Core® Insulation
The R-factor (insulation value) per
linear inch of a UniFrame window
frame is seven times greater than that
of an ordinary vinyl frame. The secret
is our patented R-Core insulation –
a high-density solid-polyurethane
insulation, like the kind used in many
refrigerator and freezer doors.
*U.S. Patent Number 4,516,356
Warm-edge Intercept® Glass Spacer System
This advanced insulated glass spacer system virtually eliminates cold-spot corners,
frost, fog and condensation. Like all spacers, it works by maintaining a consistent
space between the two panes of glass to interrupt the natural flow of heat to cold.
Unlike other spacers, Intercept is a continuous U-shaped channel that flexes as the
glass expands and contracts. The result is a stronger, more energy-efficient insulated
glass unit and a reliable seal for the life of the window.
UniFrame Glass Systems
UniFrame windows feature the very best in thermal efficiency technology and your
choice of five grades of insulating glass packages for optimal performance.
Each system incorporates either argon (40%** denser than air) or krypton
(190%** denser than air). These safe, naturally occurring gases help to block
the transfer of heat better than air which increases energy efficiency, adds
protection from the sun’s damaging rays, and helps to deaden sound.
Enhanced Protection
UV energy is the primary component responsible
for fading of furnishings and overall deterioration
of fabric quality. The more a window product
can reject or absorb of the suns UV energy, the
longer the life and quality of the furnishings being
protected. The Low-E coatings in Hi R+Plus or
Maxuus 10 helps to block this harmful UV energy.

Maxuus 7.6 glass system delivers high performance with triple pane combining two panes of multilayered vacuum-deposition Low-E insulating glass with an interior glass substrate and two insulating chambers of argon gas. The result is an insulated glass unit that is nearly six times more energy efficient than single glass. Choose your level of comfort. |

The Great Lakes UniFrame window was designed with Quality in Mind, but
don’t just take our word on it, let the product certification speak for itself.
UniFrame windows with a Low-E argon or krypton glass package meet
The Department of Energy’s ENERGY STAR requirements for your region. The
ENERGY STAR Window Program is a voluntary partnership between the U.S.
Department of Energy and participating window manufacturers. ENERGY STAR
performance requirements are tailored to fit the energy needs of the country’s
4 different regions — Northern, North/Central, South/Central and Southern
states. Your investment in ENERGY STAR windows will pay for itself over time,
and then the savings is money in the bank every year!
UniFrame windows ... good for you, good for your home and good for
the environment.
