Detroit Fiberglass Windows

Fiberglass Offers Superior Durability for Extreme Michigan

Detroit’s northern climate experiences seasonal swings in weather. Durable materials like fiberglass and vinyl provide additional protection from the elements and help keep your home comfortable no matter what the thermometer shows outside.

Pella fiberglass windows use a proprietary fiberglass composite that’s the most durable material available in windows1. Fiberglass windows have similar energy-efficient properties to vinyl windows, providing resistance to the most extreme heat and cold and damaging UV rays.  

1In testing performed in accordance with ASTM testing standards, Pella’s proprietary fiberglass has displayed superior performance in strength, ability to withstand extreme heat and cold, and resistance to dents and scratches.
Pella's proprietary fiberglass material is the strongest material for windows and patio doors, engineered for lasting durability.  Disclosure: Pella’s proprietary fiberglass material has displayed superior strength over wood, vinyl, aluminum, wood/plastic composites, and other fiberglass materials used by leading national brands in tensile and 3-point bend tests performed in accordance with ASTM D638 and D790 testing standards.

Popular Local Trends & Styles

  • Bay Windows Bay Windows

    A bay window is a notable feature of hundreds of historic Victorian homes around greater Detroit. This style can also be found in many other home styles, both traditional and contemporary, to add architectural interest. A bay window is actually a combination of three windows joined at an angle. The angled combination extends out of your wall to open up space in your room. The unique design of a bay window provides maximum sunlight and ventilation.

Pella fiberglass windows can be customized to exceed the ENERGY STAR guidelines in Michigan.

Foam-insulated frames and double- or triple-pane glass can make your windows even more energy-efficient.  
  • Modern Windows Modern Style

    Double or triple glass glazing, more commonly known as double- or triple-pane windows, can drastically improve energy efficiency. In multi-pane windows, a gap in between two or more panes of glass is filled with an inert gas, like argon, which helps reduce heat flow. In addition to insulation, the additional layers of glass on double- and triple-pane windows can also help reduce outside noise.

  • Art Deco Design Art Deco Design

    Detroit’s skyline and downtown buildings are famous for their Art Deco architecture. Many homeowners take inspiration from the metro architecture to create unique styles in their own homes. Art Deco is a bold style defined by its use of vertical lines, repetitive geometric shapes, shiny metallic accents, graphic patterns and sleek textures. Fiberglass windows in bold colors like black and used in combinations that create abnormal shapes, sizes or curves stand out in a home already decked out with Art Deco interior design elements.

Detroit Climate Recommendations

Whether it’s Lake St. Clair or the Great Lakes, Detroit’s climate is impacted by all the nearby bodies of water. Winter can bring snow and freezing temperatures to the region. Thunderstorms are common in the spring and summer. The diverse climate is a big reason why fiberglass windows are popular in the region. With a few customizations, you can improve the energy efficiency of your windows.

Low-E Protection

Get year-round protection with Low-E insulating glass. The added protection helps provide balanced insulation from Detroit’s cool winters and moderate summers.

Glass Glazing

In coastal climates close to water, your windows are more vulnerable to corrosion from the salt in the air. The closer your home is to the water, the more susceptible you are to the effects. Consider fiberglass to maintain window integrity.
