Gable Vents are a functional additional to the roof of a home. Gable Vents allow heat to escape in the Summer and prevent the formation of condensation during the Winter. Ply Gem gable vents are available in round, square, octagonal, half-round and rectangular sizes in a myriad of colours to accentuate or match your siding. Utility Vents allow for proper airflow in a specific area of the home. Utility Vents are available for garages, foundations, range hoods, dryer vents, bathroom exhaust fans, furnaces, fire-places and soffit. Ply Gem offers a variety of utility vents with matched colours to our siding.
