Specifications for 3M™ Safety and Security Window Film, Safety Neutral S35

1.0 Scope

This specification is for a combination safety window film with sun control which,when applied to the interior window surface,will help hold broken glass together and reduce the sunlight that normally would enter through the window. It provides an increased measure of protection in a broad range of uses including basic glass fragment retention, spontaneous glass breakage, seismic preparedness, safety glazing, bomb blast mitigation, Smash and Grab or Break and Entry events.Certain applications may require the film be used in conjunction with a film attachment system. The film shall be called 3M™ Safety and Security Window Film, Safety Neutral S35.

b.Drop cloths or other absorbent material shall be placed on the window sill or sash to absorb moisture accumulation generated by the film application.

6.3 Installation: The film shall be applied as to the specifications of the Manufacturer by an ADA.

a.Materials will be delivered to the job site with the manufacturer’s labels intact and legible.

b.To minimize waste, the film will be cut to specification utilizing a vertical dispenser designed for that purpose. Film edges shall be cut neatly and square at a uniform distance of 1/8″ (3 mm) to 1/16″ (1.6 mm) of the window-sealing device.

c.Film shall be wet-applied using clean water and slip solution to facilitate positioning of the film onto glass.

d.To ensure efficient removal of excess water from the underside of the film and to maximize bonding of the pressure sensitive adhesive, poly plastic bladed squeegees shall be used.

e.Upon completion, the film may have a dimpled appearance from residual moisture. Said moisture shall, under reasonable weather conditions, dry flat with no moisture dimples within a period of 30 calendar days when viewed under normal viewing conditions.

f.After installation, any left over material will be removed and the work area will be returned to original condition. Use all necessary means to protect the film before, during and after the installation.

7.0 Cleaning

The film may be washed using common window cleaning solutions, including ammonia solutions, 30 days after application. Abrasive type cleaning agents and bristle brushes, which could scratch the film, must not be used. Synthetic sponges or soft cloths are recommended.

8.0 Warranty

a) The application shall be warranted by the film manufacturer (3M) for a period of _____years in that the film will maintain solar reflective properties without cracking, crazing, delaminating, peeling, or discoloration. In the event that the product is found to be defective under warranty, the film manufacturer (3M) will replace such quantity of the film proved to be defective, and will additionally provide the removal and reapplication labor free of charge.

b) 8.2 The film manufacturer (3M) also warrants against glass failure due to thermal shock fracture of the glass window unit (maximum value $500 per window) provided the film is applied to recommended types of glass and the failure occurs within sixty (60) months from the start of application. Any glass failure must be reviewed by the film manufacturer (3M) prior to replacement.
