The quality of windows can account for high heating and cooling costs. The framing or glass can conduct heat, forcing your air conditioner to work harder to maintain interior temperatures — using more energy in the process. Upgrading to energy-efficient replacement windows will keep your home comfortable without draining money from your bank account. To guide your purchasing decisions, below are answers to several common questions about the fixtures. 

4 Popular Queries About Energy-Efficient Windows

What makes the fixtures energy-efficient?

When searching for replacement windows, look for double- or triple-pane models. Argon gas is pumped between the glass panels because it’s an inert gas with low heat conductivity that’s ideal for insulation. Krypton is another gas sandwiched between the glass layers that functions as an insulator.   

What are low-emissivity coatings?

Low-emissivity coatings are also a key feature to look for in your replacement windows. Applied directly to the glass surface, the metal or metallic oxide membrane regulates heat transfer. Choosing windows with these coatings can stop energy loss by 30% to 50%.   

How are U-value and R-value different?

When talking about building insulation, you’ll come across the terms R-value and U-value. The term R-value refers to the insulation in walls and ceilings, while U-value refers to doors and windows. When shopping for windows, the U-value of the fixtures is a factor to consider. A lower number translates to a higher insulation value.

What material is best for framing?

Some materials provide more insulation than others, so keep this in mind when choosing frames for replacement windows. Stay away from aluminum fixtures, as they conduct heat quickly. Instead, opt for vinyl models. The polyvinyl chloride (PVC) features UV light stabilizers that serve as a barrier to sunlight. The cavities can be filled with insulation to enhance their thermal resistance.
