Casement and Awning Windows

MI provides both casement and awning windows, which are known for their excellent ventilation capabilities.

Casement windows hinge on the side and open outward to the left or right, while awning windows are hinged at the top and open outward from the bottom. These styles are ideal for hard-to-reach areas, as they can be easily operated with a handle.

Sliding and Slider Windows

The slider windows from MI Windows glide horizontally and are very user-friendly, offering a space-saving option since they don’t require exterior space to open. They are available in various sizes, making them a versatile choice for both large and small openings.

Bay and Bow Windows

Create an expansive view and a feeling of more space with MI’s bay and bow windows. Bay windows consist of a central fixed window flanked by angled vent windows, while bow windows smoothly curve to create a gentle outward arc. These window styles are perfect for adding character to your home.

Double-Hung and Single-Hung Windows

One of the most popular choices, double-hung windows, allow both the upper and lower sashes to move, providing increased ventilation and easier cleaning.

Single-hung windows operate similarly but with only the bottom sash movable. MI Windows ensures that these traditional styles meet modern efficiency standards.

Specialty and Custom Windows

For unique spaces, MI Windows provides specialty and custom windows designed to fit specific dimensions and shapes. You have freedom in design, whether you’re looking for a picture window to frame your view or a custom geometric shape to add architectural interest to your home.

Energy Efficiency and Performance

When you choose windows for your home, energy efficiency isn’t just a buzzword—it’s a key component in reducing heating and cooling costs. The features that improve window performance, such as warm-edge spacers and argon gas insulation, can turn your windows into an investment in long-term savings.

Warm-Edge Spacer System

The warm-edge spacer system is a critical element in energy-efficient windows. It consists of an insulated barrier that separates the panes of glass in double or triple-glazed windows, thus reducing heat transfer. Thanks to this technology, you will likely experience less condensation around the edges of the glass and improved temperature regulation inside your home.

Argon Gas Insulation

Windows with argon gas insulation use this inert, non-toxic gas to fill the space between panes, offering better insulation than air. Argon gas reduces heat transfer because it is denser than air, helping to maintain a consistent temperature in your home and reducing heating and cooling costs.

Energy Performance Ratings

Understanding energy performance ratings is essential when evaluating the efficiency of your windows. These ratings, which include U-value and Solar Heat Gain Coefficient (SHGC), measure how well a window can retain heat and block unwanted solar radiation. For instance, a lower U-value indicates better insulation properties. Reading up on these ratings will guide you to make informed decisions and choose windows that fit your energy-saving goals.

Installation and Support

When you select MI Windows for your home, you’re investing in a product that is supported by detailed installation instructions and robust customer support services.

Whether you’re a contractor working on new construction or replacing windows, the guidance and assistance you receive are designed to ensure a seamless experience.
