About this file
This document is a specification section for mirrors, including requirements for mirror materials, fabrication, and installation. The key details are:
The specification covers silvered flat glass mirrors, including product data submittals, delivery and handling requirements, and installation procedures. It specifies source limitations to obtain mirrors and accessories from single manufacturers, and requires mirrors to be shop fabricated to the greatest extent possible. The mirrors must have flat polished edges, with edge sealing to prevent damage. Safety mirrors require film backing to be applied. The specification outlines inspection and preparation requirements for the substrate, as well as installation methods using mirror hardware. It also includes cleaning and protection measures to prevent mirror damage during construction.

MIRRORS
SECTION 08 83 00 - MIRRORS
PART 1 - GENERAL
1.1 SUMMARY
A. Section Includes: Silvered flat glass mirrors.
1.2 SUBMITTALS
A. Product data
1.3 DELIVERY, STORAGE, AND HANDLING
A. Protect mirrors in accordance with mirror manufacturer's written instructions and as needed to prevent damage to mirrors from moisture, condensation, temperature changes, direct exposure to sun, or other causes.
B. Comply with mirror manufacturer's written instructions for shipping, storing, and handling mirrors as needed to prevent deterioration of silvering, damage to edges, and abrasion of glass surfaces and applied coatings. Store indoors.
1.4 FIELD CONDITIONS
A. Environmental Limitations: Do not install mirrors until ambient temperature and humidity conditions are maintained at levels indicated for final occupancy.
PART 2 - PRODUCTS
2.1 SOURCE LIMITATIONS
A. Source Limitations for Mirrors: Obtain mirrors from single source from single manufacturer.
B. Source Limitations for Mirror Accessories: Obtain mirror-glazing accessories from single source.
C. Shop fabricate mirrors to greatest extent possible.
D. Fabricate cutouts for notches and holes in mirrors without marring visible surfaces.
Locate and size cutouts, so they fit closely around penetrations in mirrors.
E. Mirror Edge Treatment: Flat polished
1. Seal edges of mirrors with edge sealer after edge treatment to prevent chemical or atmospheric penetration of glass coating.

2. Require mirror manufacturer to perform edge treatment and sealing in factory immediately after cutting to final sizes.
F. Film-Backed Safety Mirrors: Apply film backing with adhesive coating over mirror backing paint, as recommended in writing by film-backing manufacturer, to produce a surface free of bubbles, blisters, and other imperfections.
PART 3 - EXECUTION
3.1 EXAMINATION
A. Examine substrates, over which mirrors are to be mounted, with Installer present, for compliance with installation tolerances, substrate preparation, and other conditions affecting performance of the Work.
B. Verify compatibility with and suitability of substrates, including compatibility of existing finishes or primers with mirror mastic.
C. Proceed with installation only after unsatisfactory conditions have been corrected and surfaces are dry.
3.2 PREPARATION
A. Comply with mastic manufacturer's written installation instructions for preparation of substrates, including coating substrates with mastic manufacturer's special bond coating where applicable.
3.3 INSTALLATION
A. General: Install mirrors to comply with mirror manufacturer's written instructions and with referenced National Glass Association (NGA) publications. Mount mirrors accurately in place in a manner that avoids distorting reflected images.
1. NGA Publications: "Laminated Glazing Reference Manual," "Glazing Manual" and "Installation Techniques Designed to Prolong the Life of Flat Glass Mirrors."
B. Provide a minimum airspace of 1/8 inch between back of mirrors and mounting surface for air circulation between back of mirrors and face of mounting surface.
C. Install mirrors with mirror hardware. Attach mirror hardware securely to mounting surfaces with mechanical fasteners installed with anchors or inserts as applicable. Install fasteners so heads do not impose point loads on backs of mirrors.
3.4 CLEANING AND PROTECTION
A. Protect mirrors from breakage and contaminating substances resulting from construction operations.
B. Do not permit edges of mirrors to be exposed to standing water.

C. Maintain environmental conditions that prevent mirrors from being exposed to moisture from condensation or other sources for continuous periods of time.
D. Clean exposed surface of mirrors not more than four days before date scheduled for inspections that establish date of Substantial Completion. Clean mirrors as recommended in writing by mirror manufacturer and NGA's publication "Proper Procedures for Cleaning Flat Glass Mirrors."
