Windows by Anchor Roofing

New Windows

If the windows in your Woodbury home are more than 10 years old or include only single-pane glass, they could be costing you a significant amount of money every month. Studies by the U.S. Department of Energy have proven that 30% or more of a home’s energy can be lost through inefficient windows and doors. When the cost of heating and cooling your home climbs higher every year, can you afford to let that money simply fly out the window?

Our Woodbury replacement windows have been specially engineered for thermal efficiency and easy operation. Just as importantly, they come in a wide array of styles to add great beauty to your home.

Window Materials


Windows manufactured from vinyl represent the largest market share in the replacement window business. High-quality structural vinyl is affordable, strong and provides very good energy savings, with moderate to high R-values to help reduce heating and cooling costs.

  • Economical cost
  • No painting or maintenance required
  • Outstanding energy efficiency
  • Wide variety of styles
  • Custom fit and sizing


Thanks to advanced manufacturing techniques, fiberglass windows are among the strongest and most energy-efficient windows available. Fiberglass window components are extremely durable and can be readily fabricated and customized. The resins comprising fiberglass window components are smooth and capable of accepting a wide variety of custom, color-through colors.

  • Stronger than wood or vinyl
  • Better insulating properties than wood
  • Maintenance-free and rot-proof
  • Expands and contracts uniformly, allowing the frame to maintain its integrity
  • Can be painted after installation


Wood windows are popular for custom window jobs that require unique design specifications. Wood can be painted to match any exterior color, but must be painted regularly to avoid undesirable chipping and exposure which can lead to rot. Wood windows have better insulative properties than metal, but fall short of vinyl and fiberglass.

  • Can be painted or stained
  • Wide variety of sizes to choose from
  • Does not attract condensation like a metal frame
  • Adds value and traditional appeal


Aluminum was the first type of replacement window available and continues to be one of the strongest window materials offered. Aluminum windows do not offer the high level of energy efficiency found in wood, vinyl or fiberglass windows. However, aluminum windows can be an acceptable alternative for the budget-conscious homeowner. Aluminum is often used as an exterior shell to strengthen wood windows, creating what is known as “clad” windows.

  • Affordable
  • Weather-resistant and will not rust
  • Blocks noise better than other window material types
  • Can be painted


Composite frames combine the low maintenance of vinyl with the strength and stability of wood. Their resistance to warping, rotting and heat transfer make them a great choice for busy homeowners who prefer the look of wood without the maintenance hassles.

  • Look of wood with performance of vinyl
  • Outstanding energy efficiency
  • No painting or maintenance required
  • Available in custom colors and sizes
  • Priced between vinyl and wood

How to Determine the Efficiency of  Replacement Windows

Anchor Roofing Window InstallationHow can you tell if a window is energy-efficient? Standards have been established by the National Fenestration Rating Council (NFRC), an independent, non-profit organization that administers the only nationally accepted rating system to measure the energy performance of windows, doors and skylights. The NFRC provides fair, accurate and reliable energy performance ratings, allowing architects, builders, code officials, contractors and homeowners to compare products and make informed choices.

  • U-Value. The most important measure of a window’s performance is its U-value, the rate of heat flow through a window. The lower the U-value, the more energy-efficient the window will be. U-value measures the entire window unit and is the only measurement accepted by the U.S. Department of Energy’s ENERGY STAR program.
  • R-Value. R-value is the measure of the resistance of glass to the flow of heat. The higher the R-value, the better the glass will be at insulating your home. However, R-value is not an accepted form of measurement by the NFRC or ENERGY STAR, as it does not measure the overall window unit.
  • Solar Heat Gain Coefficient. Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. SHGC is expressed as a number between 0 and 1. The lower a window’s solar heat gain coefficient, the less solar heat it transmits.

Energy-Efficient Glass Reduces Monthly Utility Bills

The glass packages available in replacement windows installed by Anchor Roofing & Exteriors include some of the most advanced features available today. At the heart of our replacement windows is a technologically advanced glass called Low-E (low emissivity) glass. Low-E glass maximizes your home’s efficiency by reducing the amount of heat entering or escaping. Microscopically thin layers of oxidized metal are applied to the glass surface, allowing filtered light to pass through while reflecting most heat energy back to its source – an incredibly efficient way to reduce energy loss.
