BU566 Applied window films (2013)

As well as allowing daylight and sunshine into a house and providing views and a connection to the outdoors, clear glazing also allows in too much heat, glare or ultraviolet light, can let out too much heat and does not give occupants much privacy. Applying a film to glazing can modify these unwanted characteristics.

The bulletin covers:

• benefits of applied films
• performance
• selecting a window film
• New Zealand Building Code requirements
• materials and installation
• film application
• care of window films
• warranties.
