Additional Factors To Consider Before Purchasing Window Replacement Glass

By considering the following factors when selecting replacement glass for your Pella windows, you can make an informed decision that meets your needs and helps you achieve the desired level of energy efficiency, comfort, and cost-effectiveness.

Window Frame Material

Pella windows are available in a variety of frame materials, including wood, fiberglass, and vinyl. Each material has its own unique properties, which can impact the choice of replacement glass.

For example, if you have Pella windows with a wooden frame, consider a glass option that provides increased insulation and protection against the sun’s rays.

This is because wooden frames are more susceptible to damage from the elements than other materials and can benefit from extra protection.

AdvancedComfort Low-E Insulating Glass or SunDefenseTM Low-E Insulating Glass would be good options for homeowners with wooden-framed Pella windows.

If your Pella windows have a fiberglass or vinyl frame, you may have more flexibility in choosing replacement glass options. These materials are more durable and weather-resistant than wood, which means they may require a different level of protection.

However, consider glass options that provide increased energy efficiency and noise reduction, such as Advanced Low-E Insulating Glass or NaturalSun Low-E Insulating Glass.

Window Style

If you have double-hung windows with two movable sashes that slide up and down, choose a glass option that is easy to clean and maintain.

This is because double-hung windows can be more challenging to access for cleaning than other window styles.

In this case, a glass option like NaturalSun Low-E Insulating Glass, which is designed to provide maximum natural light and requires minimal cleaning, maybe a good choice.

On the other hand, if you have casement windows with a single sash that swings out to the side, choose a glass option that provides increased insulation and protection against the sun’s rays.

This is because casement windows are typically more airtight than other window styles and can benefit from extra insulation.

AdvancedComfort Low-E Insulating Glass or SunDefenseTM Low-E Insulating Glass would be good options for homeowners with casement-style Pella windows.

Budget

Budget is always a consideration when it comes to home improvement projects, and choosing replacement glass for your Pella windows is no exception.

Different types of glass come with different costs, so it’s important to balance your desire for high performance with your available budget.

Keep in mind that investing in high-quality replacement glass can lead to long-term savings on your energy bills, as well as improved comfort and durability.
