What are the pros and cons of vinyl windows?

1. Disadvantages of Vinyl Window

Color customization.  Vinyl windows come in a variety of colors, but you cannot paint or stain the interior to match the decor, so it’s best to choose a neutral color.

1. Advantages of Vinyl Windows

Lower Energy Costs.  Vinyl windows keep heat in during winter and out during summer.  This reduces heating and air conditioning usage for lower energy bills.

Low-Maintenance.  Vinyl windows are nearly 100 percent scratch free. They never have to be painted, scraped, or stained and they’re easily cleaned with soap and water. Because they’re resistant to the elements, they don’t age as fast as other windows.

Affordability.  Vinyl is the least expensive of all window materials, but this doesn’t mean vinyl windows are low quality.  Vinyl is durable, and it won’t rust or corrode.  If your windows and doors are Energy-Star Qualified – all Metropolitan products are, by the way – then chances are you will quality for a tax-credit.  This saves you money and adds value to your home if you ever decide to sell.Variety.  Vinyl windows have many color, size, and style options.  They can also be custom made and sizes range widely.  Vinyl windows are available in styles from awning to picture.

What makes a window energy efficient?

Energy-efficient windows, also known as energy-saving windows reduce your home’s energy usage—and therefore, your bills!

These are the factors that make a window energy efficient.

1. Quality Frame Materials

High quality frame materials will reduce the transfer of heat and offer better insulation. Generally, aluminum windows are the least efficient simply because they conduct heat too well. Vinyl frames tend to offer better performance due to its insulative qualities.

2. Multiple Glass Panes

A single pane of glass won’t offer much insulation. Double paned windows create air pockets between the layers of glass, which are sealed shut to prevent any air from entering or escaping. 

3. Gas Fills

Energy-efficient windows will have Argon gas between window panes which offer better insulating performance than regular air. Argon gas is non-toxic, odorless, and colorless.

4. Low-E Glass Coatings

To maximize the efficiency of the glass itself, energy-efficient windows will have a Low-E coating on them to reflect infrared and UV light. Low-E is a thin metallic coating that goes on the glass and is an effective way to keep heat inside your home in the winter or to keep it out of your home in the summer.

5. Proper Installation 

The most energy-efficient window will be useless if it is installed improperly. Proper installation of a window contributes greatly to its performance. This is just as important as the frame material or type of glass and gas fill.
