> Ultimate Exteriors of Colorado has been providing quality siding, windows and doors in the Metro Denver, and foothills areas of Colorado for over 20 years.

For applications that call for vertical siding, Hardipanel is equal to our lap siding in value and long-lasting performance. Because of its structural strength, Hardipanel may be used as a shear panel siding. It can also help you achieve a board and batten siding look when combined with Harditrim® planks. All styles of Hardipanel are pre-primed with PrimePlus™ sealer and primer. This proprietary process ensures uniform coverage, which provides an excellent surface for paints and resists fungus and mildew. Hardipanel vertical siding comes with a 30-year transferable limited warranty.
