Special Offer
Our Price — $121.00

The 16” x 21” Insulated Fixed Glass Window provides additional natural light in your tiny house, cabin, cottage, guest house or workshop. Insulated windows are energy efficient and are constructed of a white vinyl interior and exterior. Double pane, energy efficient glass provides unobstructed natural light.

The availability of insulated windows is subject to fluctuation. If you’re purchasing a Kit or Fully Assembled building AND an insulated window, your order will be prioritized. If you wish to purchase windows by themselves, please call 802-297-3760 to check availability before ordering.


Our 16” x 21” insulated fixed glass window is popular for use in cottage lofts, playhouses, workshops, and garages. They are often placed higher up in the gable of a building, or on either side of a door. Insulated windows are manufactured with an integral nail fin frame for an easy and weathertight installation. The interior and exterior are constructed of high-quality white vinyl for easy maintenance and durability. Double glazed with Low-E (low-emissivity) clear glass lowers your energy costs for heating and cooling, protects furnishings from fading and reduces condensation.
