Polaris ThermalWeld Windows Reviews

The Polaris ThermalWeld window is their mid range vinyl window that is considered a very nice mid range option, although not in the same league as the Polaris UltraWeld. Consumers can expect better numbers out of the ThermalWeld, including a .29 U-value and .28 SHGC. The ThermalWeld has a bit beefier frame than some windows, but most homeowners won't notice it once installed. The ThermalWeld carries an upgraded warranty compared to the ValuSmart window.

The Polaris ThermalWeld includes a true position balancing system, sash limit locks, reinforced meeting rails, a true sloped sill, cam style locks, extruded pull rails and the energySMART glass. The ThermalWeld is a solid mid range vinyl window that I would recommend if the price point is right.

Polaris ThermalWeld Ratings

Consumers can expect slightly better numbers out of the ThermalWeld compared with the ValuSmart model, including a .29 U-value, .28 SHGC and .46 VT. Upgrades to a premium glass and krypton fills can bring the U-factor as low as .22.

All in all, some decent performance out of a mid range vinyl window. These numbers come from the nfrc.org website, which lists hundreds of window models and series, along with their U-factor, SHGC and VT numbers.

Polaris ThermalWeld Warranty

The Polaris ThermalWeld offers a lifetime warranty that applies to the mainframe and sash. The insulated glass unit carries a 30 year warranty period. The warranty doesn't cover either screen damage or accidental glass breakage. Any exterior paint carries a 20 year warranty on fading and peeling.

The warranty should be transferrable to a subsequent owner and then the warranty is good for 30 years from when the windows were purchased. As with all warranties, you should read them in their entirety prior to your purchase.

Website Editor's Answer

Dianne, you as the homeowner should have the limited lifetime warranty with you when the job was completed. Call up whomever did the install and make sure you get the warranty from the company. I'm glad to hear that you like the windows and that your home is quieter -- Polaris makes a good vinyl window.
