Replacement Double Hung Windows

The multi-chamber design helps trap dead air to produce an effective barrier, while the extra-thick, fusion-welded frame and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration, adding up to greater energy savings – and lower utility bills.

Double Hung Windows – Features and Benefits

  • The multi-chamber design of the Sheffield Window helps trap dead air to produce an effective insulating barrier
  • Double-Hung-Replacement-WindowFusion-welded frame and sashes provide superior structural strength and create a permanent barrier against air and moisture infiltration
  • Ensuring easy operation, the constant force balance system and heavy-duty operating hardware continue to operate perfectly, even after decades of regular use
  • Heavy-duty SteelForce™ reinforcement is placed within the sashes at the meeting rails to ensure extra protection at this very critical and often used location
  • The Intercept Spacer System helps reduce conducted heat loss through the window and is better at retaining insulating gas than many conventional designs
  • Triple-barrier weatherstripping between the sash and jamb for superior protection from air and water infiltration
  • Sloped sill helps prevent water and air infiltration, forcing water to drain to the exterior of the window
  • Optional ClimaTech insulated glass packages available. Consult your window professional for the optimal glass package required for your home and climate zone

Uncompromising Replacement Window Quality

Window Replacement HoustonInsulated Glass – a combination of two or more panes of glass with hermetically sealed air space between.

Argon Gas – a safe, colorless, odorless, nonflammable, nontoxic inert gas that is heavier than air. This insulating gas between the panes of glass counteracts heat/cold conduction. It also helps reduce noise infiltration – so your home will be more energy-efficient and quieter.

Krypton Gas – this super-insulating gas is denser than argon and therefore, provides better performance properties.

Low-E Glass – a special type of glass with microscopically thin, undetectable metallic coatings applied to its surface that act as a thermal barrier. In winter months, Low-E helps reduce heating costs by reflecting indoor heat back into the room. During the summer, Low-E lets in visible sunlight while minimizing infrared and ultraviolet solar energy that can increase cooling costs and cause curtains, carpets and furniture to fade.

PPG Intercept Warm-Edge Spacer System – a sealed, one-piece alloy in a U-channel design that creates an effective thermal barrier to reduce conducted heat loss through the window.

Houston Window ReplacementThe Intercept Warm-Edge Spacer keeps the edges of the window glass warmer and reduces condensation problems around the window perimeter. Although both windows pictured above are built with Low-E glass and filled with argon gas, the window with the Intercept, Warm-Edge Spacer maintains superior thermal performance despite fluctuations in temperature.

High R-Value – R-value is the resistance to heat flow, so the higher the R-value the better the insulating performance.

Low U-Factor – U-factor (also referred to as U-value) represents the rate of heat flow through a glazing system. The lower the U-factor, the greater the resistance to heat flow and the better the insulating power.

SHGC – Solar Heat Gain Coefficient represents the fraction of solar radiation admitted through a window. The lower the SHGC, the less solar heat the window transmits into the home, which can help reduce air-conditioning costs during summer months.
