Replacement Windows for Your Boulder Home

Here at Northern Lights we provide replacement windows based on durability and longevity, not profit margins. This trusted practice will provide you with a high quality, long-term upgrade for your home whilst minimizing the environmental impact and possible financial strain in the future.

Types of Window Materials

Regardless of the look you want for your windows, the level of energy efficiency or the length of time you want them to last, Northern Lights Exteriors has an option that will fit your needs perfectly. We won’t steer you toward buying one particular type of window, we’ll give several high quality options to choose from after meeting on-site to understand the footprint of your exact home needs:

  • Wood
    • We’re proud to be a Pella Certified Contractor and trust in the quality of Pella wood windows. Pella is an incredible choice for energy efficiency while keeping the natural aesthetic of wood.
  • Fiberglass
    • Fiberglass can reduce heating and cooling costs throughout the year by doing an excellent job of insulating a home’s interior.
  • Vinyl
    • Vinyl windows from Simonton, a respected industry leader.
    • BOUNS – With Simonton we’ve negotiated free upgrades for our customers.
  • Aluminum-clad
    • Natural wood interior and weather-resistant, aluminum-clad exterior will never expand, contract, warp, or rot.
  • Composite
    • Due to the availability of superior alternatives in other categories, we often discourage Denver homeowners from choosing composite windows. Composite windows contain a sufficient amount of fiberglass material to differentiate them from vinyl windows.
  • Energy Efficient

Types of Functionality:

  • Single hung
  • Double hung
  • Awning
  • Sliding
  • Bay and bow
  • Picture
