The best value aluminum windows

Aliplast Max Light Modern is the superior choice for those seeking to maximize glass area with minimal frame obstruction.

Why is sash + frame height important for your bottom line?

In luxury homes, slim sash and frame profiles mean more glass, more light, and a clean, modern look buyers expect.

What does that mean for you?

• Higher resale value – more natural light and frameless aesthetics help you justify a higher price point.
• Stronger reputation – delivering homes with better design and comfort sets you apart from competitors.

Smaller frames aren’t just a design detail—they help you build more profitable, desirable homes.

Energy-efficient at a reasonable price Aluprof MB-86N

Our recommendation for combining strong thermal efficiency with a very reasonable price is the Aluprof MB-86N.

A slightly more expensive option is the Aliplast Genesis 75, though it comes with a noticeably thicker frame at that price point.

If you’re looking for a slimmer profile with excellent thermal performance (U-Factor 0.15), consider the Aliplast Max Light Modern.
However, be aware that it’s more expensive than thicker options like MB-86N, MB-79N, or Genesis 75.

A smart alternative:

For most U.S. projects, a U-Factor of 0.17 is more than sufficient.

In that case, Aluprof MB-79N offers the best balance of cost and performance. You don’t need to overpay just to get down to 0.16—unless your project specifically requires it.
