Alpen windows are made in Louisville, Colorado with local support and services. They operate as European tilt-turn style and single hung windows with German hardware. These residential windows are the highest quality with super-insulating and thermally efficient construction. Utilizing three decades of experience to incorporate lightweight, suspended-film technology that eliminate air drafts and contribute to the home’s favorable R-value and low HERS score. We have used them for 4-years now in the back Tandem House and could not be more happy with them. They are easy to operate, they are strong (not chintzy) and are always a topic of conversation when people come over.
Exterior doors are Pella fiberglass. Pella is known to be stylish but also for their easy maintenance, energy efficiency and ability to stand up to extreme weather. We are happy with the decorative glass features on the front door side-lites and balcony door that give the home a custom and classic feel.
