Common materials include wood, vinyl, fiberglass, and aluminum. Each material has its own advantages in terms of durability, maintenance, and insulation.

Consider the architectural style of your home, your functional needs (like ventilation), and energy efficiency when selecting window styles. Popular styles include double-hung, casement, sliding, and bay windows.

Energy-efficient glazing refers to window designs that use multiple panes of glass, gas fills, and low-emissivity (Low-E) coatings to reduce heat transfer and improve insulation.

It typically depends on the type of window and its condition, but on average, windows should be replaced every 15-30 years. Signs that it’s time for replacement include drafts, difficulty opening/closing, and visible damage.

Proper insulation for doors and windows helps to reduce energy costs by minimizing heat loss in winter and heat gain in summer. It also improves indoor comfort.

While DIY installation is possible, it is often recommended to hire professionals to ensure proper fitting, sealing, and insulation, which can prevent future issues.

Yes, look for products made from sustainable materials, energy-efficient designs, and those that have certifications such as ENERGY STAR or similar eco-labels.

Look for durability, energy efficiency, security features, style, and the compatibility with your home's design. Also, consider the type of material and the level of maintenance required.
