Why Allegheny Millwork & Lumber?

How New Windows Contribute to Lower Energy Bills

Investing in new windows can significantly contribute to lower energy bills in various ways. One of the primary ways is through improved insulation. Modern windows are designed with advanced materials and technologies, such as Low-E coatings and multiple panes of glass, which minimize heat transfer. This means that during hot summers, the windows keep the indoor air cooler by preventing outside heat from entering, while during cold Pittsburgh winters, they retain the indoor heat, reducing the need for heating and cooling systems to work as hard.

New windows also help lower energy bills by reducing air leakage. Properly installed and sealed windows prevent drafts, which means less outside air enters the home, resulting in a more consistent indoor temperature. This leads to less reliance on heating or cooling systems to compensate for temperature fluctuations, ultimately saving energy.

Some of our top window brands are Energy Star certified, meeting strict energy efficiency standards set by the Environmental Protection Agency (EPA). Choosing Energy Star-rated windows ensures that you’re investing in products that will significantly reduce your energy consumption, leading to substantial energy savings over time.

When to Replace Your Windows

  • Drafts and Air Leakage: If you feel drafts or notice air leaking around the windows, especially when they are closed, it suggests that the seals may have deteriorated, and the windows are no longer effectively insulating your home.
  • Difficult Operation: Windows that are challenging to open or close, or that stick and don’t move smoothly, may indicate issues with the frame or hardware. This can compromise the security and functionality of the windows.
  • Water Leakage or Condensation: Water leaks during rain or excessive condensation between the windowpanes can indicate seal failure or issues with the window’s insulation, leading to reduced energy efficiency.
  • Visible Damage: Cracks, rot, or warping in the window frame or sash are clear signs of window deterioration and may indicate that it’s time for replacement.
  • Noise and Soundproofing: If you hear excessive outdoor noise even when the windows are closed, it may suggest that the windows are not providing sufficient soundproofing.
  • High Energy Bills: A sudden increase in your energy bills may be related to poor window insulation, which can lead to energy loss and higher heating or cooling costs.
  • Fading or Discoloration: Sunlight exposure over time can cause fading or discoloration of window frames and glass, indicating that the windows may be aging and losing their effectiveness.

Types of Windows Available for Expert Installation By Allegheny Millwork & Lumber

  • Single-Hung Windows: These windows have two sashes, but only the bottom one is movable. The top sash remains fixed, making them easy to clean and ideal for homes with limited exterior space.
  • Double-Hung Windows: Both sashes in double-hung windows can be opened and closed independently, providing better ventilation options and facilitating easier cleaning.
  • Casement Windows: Casement windows are hinged on one side and open outward like a door. They offer unobstructed views and excellent ventilation when fully opened.
  • Awning Windows: Awning windows are similar to casement windows but are hinged at the top and open outward from the bottom. They are commonly used in areas that need ventilation even during light rain.
  • Sliding Windows: Sliding windows have one or more movable sashes that slide horizontally along tracks. They are space-saving and easy to operate.
  • Bay Windows: Bay windows extend outward from the exterior wall, creating a small nook inside the home. They typically consist of one large, fixed window flanked by two smaller operable windows on the sides.
  • Bow Windows: Bow windows are similar to bay windows but have a more rounded appearance, creating a gentle curve from the exterior wall.
  • Skylight Windows: Skylight windows are installed in the roof or ceiling, allowing natural light to enter from above. They are popular in areas with limited wall space or to add architectural interest to a room.

How to Care For Your New Windows

Proper maintenance and care are essential to ensure the longevity and optimal performance of windows after installation. Regular cleaning is a fundamental part of window maintenance. Dust and debris should be wiped off the frames and sills using a soft cloth or a gentle cleaning solution. For glass panes, a mixture of mild soap and water can be used to clean away dirt and grime. Avoid using abrasive materials or harsh chemicals that could damage the window’s surface. It’s also important to inspect the window’s seals and weatherstripping regularly for signs of wear or damage. If any issues are detected, they should be addressed promptly to prevent air or water leaks. Additionally, lubricating the window’s moving parts, such as hinges and locks, will help maintain smooth operation. Seasonal check-ups by professionals are recommended to assess the window’s condition, ensuring that any potential problems are identified and resolved early on. By following these maintenance practices, homeowners can preserve the beauty and functionality of their windows for many years, maximizing their energy efficiency and enhancing the comfort and aesthetics of their home.
