Homeowners looking to replace their windows often wonder whether thick glass is a good choice. After all, a thicker material should insulate better, right? Learn what thicker glass windows offer and how they compare to double-pane windows. With this information, you’ll feel better informed when shopping for replacement windows in Columbus, OH.

Pros of Thicker Glass Windows

  • Durability: While standard window glass is just 0.1 inches thick, increasing this to 0.3 inches thick improves durability. Thicker glass is less likely to break, which could benefit families with rambunctious kids.
  • Security: Thicker glass windows aren’t just safer for families—they also add a layer of security by being more difficult to break. Consider windows up to 0.5 inches thick if you’re concerned about break-ins.
  • Soundproofing: Windows with 0.7-inch-thick glass provide better soundproofing than thin windows, reducing noise transfer from the outside. This is most beneficial for homes in noisy neighborhoods.

Cons of Thicker Glass Windows

  • Heavier weight: Thicker glass windows weigh more, making them more difficult to install. Be sure to enlist a professional window installer’s help if you opt for windows with thick glass.
  • Barely better insulation: Even 0.7-inch-thick glass provides a mere 0.1 percent reduction in heat loss compared to standard 0.1-inch-thick glass. While glass is a better insulator than metal, it still transfers heat fairly efficiently, meaning a single thick pane of glass is not ideal for home insulation.
  • Higher cost: Thicker glass comes at a premium. Choosing a medium glass thickness with a laminating layer to improve soundproofing and insulation may be more cost-effective.

Pros of Double-Pane Windows

  • Higher levels of insulation: By trapping air between the sheets of glass, double-pane windows reduce heat loss by 80 percent compared to single-pane windows of the same thickness. The space between the panes can also be filled with an insulating gas, such as argon or krypton, to further reduce heat transfer.
  • Reduced condensation: Double-pane windows don’t promote condensation like single-pane windows, limiting mold growth and improving indoor air quality.
  • Even better soundproofing: Thick glass is more soundproof than thin glass, but double-pane windows are even better, especially if they’re laminated. This is a significant advantage for homeowners who value peace and quiet.

Cons of Double-Pane Windows

  • Relatively breakable: Durability is the biggest weakness of double-pane windows because each pane tends to be thinner. Plus, if one pane cracks, you have to replace the entire window. Choosing double-pane windows with medium or thick laminated glass helps overcome this drawback.
  • Difficult to repair broken seals: Double-pane windows are vacuum-sealed for maximum performance. If this seal breaks, the entire window may need to be replaced to restore efficiency and soundproofing.
