Every window is made in Michigan.
We make every WeatherGard window and door here in Michigan. We source all of our components from American companies. We get our raw materials from only American and Canadian companies. When you buy windows from us, you’re buying a high-quality home-grown product.
The most efficient glass in the world comes standard.
The best windows in the world come with glass made by Cardinal®, including all windows produced by household names like Pella® and Andersen®. It’s the best insulated, longest lasting glass pack available, and we’re among the only Michigan window manufacturers who can offer it.
Low-emissivity (low-E) coatings prevent heat from passing through glass, and can reduce energy loss by up to 85% (Kennan & Rissman 2014). Our standard low-E glass easily exceeds the latest Energy Star 6.0 requirements, but that’s only half the story, since the Northern climate standards don’t make sense for Michigan. They reward windows that let in heat from the sun, to warm the home during winter. But we get almost no sun during winter—and we get lots in July.
We’ve designed our glass offerings to suit Michigan homeowners. We didn’t go with glass that sounds great just because it’s Energy Star certified. We’ve gone a step further to make sure that our windows don’t create hotspots during summer, and drive up A/C costs.
LoE2-270 plus LoE-i89
Every window comes with two coatings. First is
LoE2-270, applied to the exterior pane. This would be highly efficient and comfortable in Michigan by itself, but we add an interior LoE-i89 coating as well, to deliver performance normally achieved only by boutique products.
Table A The LoE2-270 plus LoE-i89 glass pack exceeds Energy Star 6.0 requirements for Michigan’s climate, and more importantly, makes your home comfortable during hot Michigan summers, with low solar heat gain.
LoE3-366 plus LoE-i89 is the gold standard.
For truly cutting edge performance, we offer Cardinal’s best insulated glass. Picture this: in January, when it’s a frigid 20°F outside, a LoE3-366 glass surface will remain at 60°F inside. And LoE3-366 will also protect your flooring and furniture against color fade.
Table B The LoE3-366 plus LoE-i89 glass pack exceeds Energy Star 6.0 requirements for Michigan’s climate, makes your home comfortable during hot Michigan summers, and provides exceptional performance in the winter.
Glass units are filled with insulating argon.
Instead of filling the sealed space between the panes of glass with air, we use moisture-free argon40, which is substantially more resistant to thermal transfer than air (Sabatiuk 1983). Argon boosts energy efficiency and is also completely safe—it’s an inert, non-flammable, and non-toxic gas.
