Review of Milgard Aluminum Windows

Review of Milgard Aluminum Windows

We at Brennan know an informed consumer is a smart consumer and there are many options for today’s homeowners to choose from. So, we’re focusing on Milgard, one of our premium window suppliers, and one of their most popular window lines: the aluminum series.

Aluminum is a popular window material choice because it is lightweight, durable, low maintenance, and malleable. But what makes Milgard’s aluminum line a popular choice?

Milgard has channeled the malleability and strength of aluminum to create frames which place the focus on the glass and subsequently, the views it offers. For homeowners seeking strong windows and plenty of natural light, the malleability and strength of aluminum pay off as high-value upgrades for the home.

Are Milgard's Aluminum Windows Energy Efficient?

Milgard has developed a “barrier” mechanism in their aluminum construction that enables them to add insulation inside of the window frame. Their Thermally Improved Aluminum windows, (also known a Thermal Break), consist of extruded aluminum, this is where a “channel” is cut through the aluminum. Polyurethane, a kind of plastic, is one of the most efficient insulation materials available on the market. This material, poured into the channel effectively helps regulate the temperature in your home.  

Thermally broken aluminum windows have a plastic channel to reduce thermal transfer.

The hollow space created during extrusion allows a highly insulating polyurethane barrier to be inserted into Milgard’s aluminum frames.

When researching on the most energy efficient window material, you'll find that aluminum, is a major conductor meaning it is less effective in neutralizing temperature fluctuations. You'll want to consider your local energy codes before purchasing aluminum windows regardless of the manufacturer.

Milgard Aluminum Window Construction

To make exceptional aluminum windows, Milgard uses high-quality components. Their rollers, locks, frame members and hardware are designed to keep their windows in the forefront of appearance, security, and strength. Many are Milgard exclusive designs for their six window styles, offering performance you won’t find anywhere else.  

One such example of the modern design of this line is Milgard’s take on aluminum casement windows. Casement windows are an asset when you’re seeking ventilation with a sleek profile. Milgard’s version of this window style is designed with a delicate frame and hardware that is anything but bulky.

Through normal wear and tear, inclement weather, and years of use, aluminum windows have an extremely long life. In fact, aluminum windows are some of the most popular for those living in hurricane-prone areas due to their durability in high winds and beating rain.
