When it comes to window replacements and upgrades, the Andersen 400 Series casement windows are among the most popular choices for homeowners. Known for their durability, energy efficiency, and elegant design, these windows are built to last and provide a great return on investment. In this blog post, we will dive deep into the various components that make up the Andersen 400 Series casement windows, helping you gain a better understanding of what sets them apart from other window options on the market.

The Frame and Sash

The frame and sash are essential parts of any window, as they provide the structure and support for the glass panes. In the Andersen 400 Series casement windows, the frame and sash are made from a high-performance composite material called Fibrex?. This material is composed of reclaimed wood fibers and thermoplastic polymer, making it twice as strong as vinyl and resistant to rot, decay, and fungal growth.

Fibrex? also offers excellent insulation properties, helping to keep your home comfortable in all seasons. The low-maintenance material does not require painting and will not warp, crack, or fade over time.

High-Performance Glass

Andersen 400 Series casement windows come standard with High-Performance? Low-E4? glass. This glass has a special coating that reflects heat, keeping your home cooler in the summer and warmer in the winter. Additionally, it blocks up to 95% of harmful UV rays, protecting your furniture, carpets, and curtains from fading.

For those who live in colder climates, there is also the option to upgrade to High-Performance? Low-E4? SmartSun? glass. This glass offers even better energy efficiency, with a U-factor up to 47% lower than ordinary dual-pane glass.

Hardware Options

The hardware of a casement window is responsible for its functionality, including opening, closing, and locking. Andersen 400 Series casement windows feature durable, corrosion-resistant hardware that is designed to last. The standard hardware includes a single-arm operator, which allows for smooth and easy operation of the window.

Homeowners can choose from a variety of hardware styles, finishes, and colors to match their home's aesthetic. Options include traditional, contemporary, and transitional styles, with finishes such as satin nickel, oil-rubbed bronze, and antique brass.

Insect Screens

Insect screens are essential for keeping bugs and other pests out of your home while allowing fresh air to circulate. Andersen 400 Series casement windows come with TruScene? insect screens, which are made from a micro-fine stainless steel mesh that is nearly invisible. This allows for a clear view and increased airflow, without compromising on insect protection.

Why choose the tilt and turn opening method?

Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
