Choosing the right windows is one of the most important steps in designing your home. A good window can enhance the look of your house and increase its value, while a poorly-made window can ruin an otherwise great design.

It’s important to choose high quality windows because they will last longer and save you money in the long run. They also contribute to energy efficiency by reducing air infiltration as well as heat loss through the glazing system.

Energy efficiency. The U.K. Department of Energy estimates that replacing old, inefficient windows with high-performance ones can reduce heating and cooling costs by 30 percent or more.

Durability and warranty. High-quality windows should be made of strong materials and have warranties that cover them for at least 20 years — or the life expectancy of the product.

Style and appearance. Make sure your new windows fit in with the overall look of your house and complement any existing features such as woodwork or shutters.

Cost. High-quality windows can cost more than their lower-end counterparts, but they may also outlast them by decades — making them a sound investment over time.

The first step in choosing the right windows for your home is to determine what kind of window you need. There are many different types of windows on the market today, but most fall into two categories: vinyl and wood. Vinyl windows are low maintenance and come in a variety of colors, styles and sizes. Wood windows are more expensive than vinyl, but they have better insulation qualities and can be customized with paint or stain.

Use a tinted glass that blocks UV light but lets in visible light in order to preserve color vibrancy in artwork and other work displayed inside your home. Tinted glass also helps reduce fading on furniture fabrics by blocking UV rays while still allowing light into rooms through natural daylighting opportunities like skylights or clerestories (vertical window panels).

Choose double-hung windows with sashes that slide up and down rather than tilt in and out. Sliding sashes provide greater ventilation by allowing you to keep them open during warm weather without compromising security or privacy.

Another factor to consider when choosing new windows is whether or not they should be double-paned. Double-pane windows are generally more expensive than single-paned windows, but they also offer better insulation properties. This can be especially beneficial if you live in an area where temperatures fluctuate dramatically throughout the yearbecause double-pane windows will keep your house warmer during the winter months and cooler during the summer months.
