Adding a dormer window to your Handy Home building acts like a skylight to increase natural light inside the building without sacrificing security. The window panes are of tempered glass. For increased security the window is not operable. This dormer window kit is an option only for the Majestic, Berkley and Sequoia models of Handy Home buildings. This addition should be shingled to match your existing building. Shingles are not included and must be purchased separately.
