Carp’s is the authorized replacement contractor for Integrity® Windows and Doors in Omaha, Nebraska.

You’ll love replacing your old, drafty windows with energy-efficient windows from Integrity. Created by the people at Marvin, Integrity is the world’s largest and most experienced manufacturer of windows and doors made with Ultrex®, a state-of-the-art pultruded fiberglass material that is unmatched in strength and durability. Integrity windows combine classic craftsmanship with the strength of Ultrex to deliver beauty, value and virtually maintenance-free performance.




Integrity is a beautifully, durably made window that will also lower energy bills for you. Integrity’s ENERGY STAR qualified products save homeowners 15%,on average, in energy costs.

Ultrex is one of the most durable materials that can be used for window construction. With over eight times the strength of vinyl, and three times the strength of Fibrex, Ultrex products hold up to the elements better than other windows in our harsh, Midwest climate. Windows constructed with Ultrex require using less material in the frames, which results in more glass space for you. Another advantage of Ultrex is it’s extremely low expansion/contraction rate. It moves at the same rate as glass, which means you will not have to worry about seal failures, stress cracks, or air leaks along the corners of the frames.
