Material
Vinyl windows are made from a type of plastic called polyvinyl chloride (PVC). PVC is a durable material that is resistant to rot, decay, and insects. It is also a good insulator, which can help to save energy. However, vinyl windows can be more expensive than other types of windows, and they can sometimes be difficult to repair.
Construction
The construction of a replacement window is also important to consider. The frame of the window should be made from a strong material, such as aluminum or fiberglass. The glass in the window should be double-paned, with a layer of gas between the panes to help insulate the window. The window should also have a good weatherstripping to help keep out drafts.
Energy efficiency
The energy efficiency of a replacement window is determined by a number of factors, including the U-factor, the R-value, and the Solar Heat Gain Coefficient (SHGC). The U-factor measures how well the window insulates against heat loss. The R-value measures how well the window resists heat flow. The SHGC measures how much solar heat the window allows to pass through. The lower the U-factor and the higher the R-value and SHGC, the more energy efficient the window.
Price
The price of replacement windows can vary depending on the material, the construction, the energy efficiency, and the size of the window. The most expensive windows are typically made from high-quality materials, have a good construction, and are very energy efficient. However, there are also many affordable replacement windows available that can provide good performance.
When choosing replacement windows, it is important to consider all of the factors listed above. By taking the time to choose the right windows, you can save energy, improve the appearance of your home, and increase its value.
