All of these factors determine the cost per square foot.  Labor and warranty are included.

Example: The larger the panels of glass, the lower the cost per square foot to install.  A patio door has two panels, one is stationary the other one slides.  Total square footage for an average 6 foot opening is 36.  However, the cost to apply film to a French door with 36 individual panes is more because you have 36 individual panes rather than two.  The smaller the glass the more labor intensive.

The film cost and the warranty remain the same with most Oasis Films.  The homeowner usually chooses the film that best suits their needs and allows them the most benefits.
