It is less expensive, but offers relatively little resistance to impact and breaks into jagged pieces. It breaks into small fragments, which are less likely to cut. It is more expensive than float glass and is more impact resistant as well. However, once it breaks, it falls into small pieces and does not stay in place. This is not desirable when trying to keep wind pressure out of a house.
Laminated glass is more expensive than either float or tempered glass.
It can be scratched and can yellow from sun exposure. Coatings can be added to the face of the glazing to make it more resistant to scratching and yellowing. These films come in several varieties with different capabilities. Some films are intended to increase the impact resistance of glass and applied films may be sensitive to scratching. If installing the film on existing windows, be sure what is installed has been tested for impact resistance.
