Kolbe Means Customization.  Kolbe Windows & Doors offers an array of window collections, along with nearly limitless custom options, that provide architects and homeowners the freedom to create and execute truly unique designs. Whether you need to match the timeless style of a historical building, meet strict local energy codes or dramatically extend living spaces to the outdoors, Kolbe windows and doors are customized to fit your needs.

All of our casements feature a specially designed weather stripping system that seals tight and secure to keep out heat and cold. We combine this with heavy-duty operating hardware that makes opening (a full 90º for easy cleaning) and closing a breeze. Semco's extruded aluminum exterior casements are virtually maintenance-free and never need painting. They come in seven standard colors and your choice of three decorator colors.

Semco casements are available assembled into your choice of 30°, 45°, or 90° angle bays.
