Benefits of Replacing Your Colorado Home’s Windows

Many of us appreciate the allure of a historic residence. However, aging infrastructure can substantially increase energy expenditures. Heat loss or gain through windows is particularly responsible for high energy costs. In that light, energy-efficient windows can be a practical solution for today’s homeowners.

Nex-Gen experts understand the importance of windows. Our Marvin Infinity replacement windows are made from superior Ultrex fiberglass. Ultrex is 8 times stronger than vinyl and is resistant to leaks and seal failures. It is also durable, resisting structural distortions during rapid temperature changes. In other words, Ultrex fiberglass does not warp.

Integrity’s dual-pane windows with low-E coating can also reduce your energy costs by a phenomenal 33%.

Signs It’s Time for Window Replacement

It’s time to replace the windows at your Fort Collins home when:

  • They have lost their tight seals, making your house drafty and cold during stormy weather.
  • They are cracked, and there are signs of decay from water condensation.
  • The frames are rotten, and the sashes are broken.

Our Infinity window experts provide exceptional workmanship and efficient installations.
