Polaris ThermalWeld Windows
Polaris ThermalWeld Windows

Polaris ThermalWeld comes with only windows.

The manufacturer doesn’t offer any doors from this product line.

Contradictorily, Polaris UltraWeld is available in both doors and windows.

Their premium vinyl patio doors are super strong and energy efficient.

They have an updated design.

In addition, the vinyl windows from Polaris UltraWeld can reduce electricity bills by 10% to 25%.

  • Construction

Windows from Polaris ThermalWeld have a slim and lightweight design. They come in a standard size. These windows are not bulky, making them perfect where you want to save space.

In addition, installing the windows will be easygoing due to their lightweight construction.

In opposition, doors and windows from Polaris UltraWeld are slightly bulkier and thicker. Their heavy-duty construction ensures maintenance-free for a lifetime. They will surely last several years.

However, you will need a helping hand to install them as they are a little bit heavier.

  • Special Benefits

Windows from Polaris ThermalWeld have a narrow profile design.  Apart from saving space, they will offer ample light inside your house.

Contrarily, doors and windows from Polaris UltraWeld have an elevated sill dam to raise increased structural numbers. Plus, their heavy-duty construction offers a precise air-tight seal.

Cold from the outside house will not be able to enter inside.

  • Interior Window & Muntin Colors

Polaris ThermalWeld comes with five interior window & muntin color options: white, tan, medium oak, cherry, and vintage pecan.  Tan can be a perfect pick if you prefer a neutral window color that goes well with anything you choose.

 Vintage pecan appears to be a perfect option for enhancing the overall appearance of the window.  It can even match your existing wood finishes. The detail will be eye catchy.

On the other hand, Polaris UltraWeld offers white, tan, medium oak, dark oak, cherry, and vintage pecan. The unique dark oak can create a bold traditional look. It is a perfect choice if you prefer minimal maintenance.

  • Exterior Laminate colors

Unfortunately, Polaris offers no Exterior Laminate colors for their UltraWeld series.  But, there are four Exterior Laminate color options for Polaris ThermalWeld: wicker, Chocó brown, bronze, and coal black.

If you want to add a richer color with a vibrant shade, Chocó brown is a perfect choice.  But wicker is also an excellent choice to add warm undertones to windows.

Coal black seems an exception pick to add a dark, deep, intense, and classic appearance to the windows.

  • Glass Options

Polaris ThermalWeld comes with regular glass options like other products of this brand. But they are still a decent choice to last several years.

Conversely, windows from Polaris UltraWeld have etched glass with double Strength. They are super strong. Plus, it adds a frosted look to the glass surface.

You can also use Krypton to fill in this window glass to make it gas-filled. It is entirely safe and non-toxic.

Which Window & Door Line Is Better For You?

Before choosing a particular product series, you must determine your household requirements and what you expect from a specific window or door. Polaris ThermalWeld appears to be a good choice if you want basic and affordable windows.

But you can’t expect them to last as long as some premium-grade series.

On the contrary, Polaris UltraWeld is overall a better choice if you prefer super-durable products. Plus, the product line has both doors and windows. You don’t need to choose doors separately from another product series.
