Additional Glass Options – For even higher performance, Milgard offers these door and window glass options.

  • Tempered – Tempered glass is extremely strong and often used for its safety characteristics. Not only is it extra strong, but when it breaks, it breaks into little pebble-like pieces without sharp edges. Tempered glass is ideal for reducing the likelihood of injury in the event of breakage in applications like patio doors, sidelites and bathroom enclosures for showers and tubs.
  • Laminated – Laminated glass is highly effective in reducing noise. It also eliminates 99.9% of ultraviolet rays, providing the highest degree of protection from the sun for your home furnishings. Concerned about excessive outdoor noise? Get the utmost protection against noise with our Sound Control Windows.
  • Argon/Air Mix – Optional argon gas, used between panes, is also available to further improve thermal performance.

Dramatically increase your home's curb appeal by being creative with our virtually endless grid options. Select grid choices placed inside our insulated glass units for easiest window cleaning.

Every window project is different. It's hard to provide an accurate cost range as a house can vary greatly in the number and size of its windows. Costs also depend on the frame material and glass options. Double and triple-glazed windows, or those filled with argon gas, increase energy savings but add to initial upfront costs. Often government or power company incentives include additional tax deductions or rebates for making energy-saving improvements to your home. These incentives may significantly reduce a project's total costs. You may be pleasantly surprised to discover how affordable a window replacement project can be.
