Mirrors can be made in many different styles, shapes and edgings. Modern multi-coated mirror is manufactured with silvering quality float glass and stringent quality controls to provide a high quality, corrosion resistant (copper free) mirror.
The most common safety mirror is Vinyl Back Safety Mirror. It provides protection in the event of accidental breakage as fragments do not fall down, and as the mirror is not penetrated, serious injuries are avoided. It complies with NZS 4223 and AS/NZS 2208 as a Grade A safety glass.
It can be supplied cut to size, drilled and edge worked.
Manufactured in: 4, 5 and 6mm
Interior Design Panel Glass
Lacobel SAFE is a coated glass with a protective vinyl film applied to the painted surface. It is used for internal applications such as wardrobe doors, furniture cabinetry, shop fit outs and wall cladding. Having a glass surface, it is easy to clean and maintain. It is often used as an alternative to whiteboards. Other brand names are Vinyl Deco Glass and Optipanel TM.
Vinyl Deco Glass/OptipanelTM: manufactured in 4mm White only.
Lacobel SAFE manufactured in 3-12mm in 37 different colour options.
A range of low wattage pads are available from various suppliers which are fitted behind the mirror. The operating temperature is reached within a few minutes resulting in the mirror remaining clear of condensation in even the steamiest bathrooms.
The mirror pads are permanently wired into a light circuit
or shaving socket and can be left running continuously.
Mist free Mirror Installation
Thermostats and transformers are unnecessary. The demister pads can be attached to existing mirrors and
should be no closer than 150mm from fixing holes. Demister pads demist only the area on the mirror the pad covers.
500mm x 350mm 30 watts
550mm x 500mm 50 watts
550mm x 850mm 70 watts
550mm x 1100mm 90 watts
Venetian mirror is available in 4mm annealed and is an alternative choice for privacy/surveillance use. It has strips of clear glass between strips of mirror and although not giving complete privacy, the level of visual penetration is low from the subject side. This is due to the reflection drawing the eye away from the clear strips. From the viewing side, the painted strips on the reverse of the silver allow the eye to view through the clear strips to the subject side.
One Way Vision Mirror
6mm MirrorpaneT.M. is commonly used for one way vision applications and is ideal where surveillance, security and discreet observation is required.
MirrorpaneT.M. transparent mirror is intended for interior applications and must be installed with the reflective surface facing the brightly lit side of the room (subject side). (Refer diagram).
When lighting is installed to maximise one way mirror observation, the lighting source must not shine directly on the glass, as this will reduce the effect intended. MirrorpaneT.M. can be toughened but some optical distortion may occur from this process. MirrorpaneT.M. can be laminated. MirrorpaneT.M. is not suitable for outside applications.
Note: Visible Light Transmission = 12%
Visible Light Reflection = 60%
Double Sided Tape and Mastic
Certain sealants and double sided tapes are not compatible with mirror backing paint. Double sided tape must also be capable of bonding the mirror to the wall permanently. Adhesives applied in horizontal strips will gather moisture and not allow circulation of air, in time, causing corrosion. When using a mirror Mastic or adhesive the glue contact area must be greater than 0.2m2 per 1m2. The thickness of the glue and associated double sided tape should be 1.6 to 3mm. Use 5 strips of double sided tape vertically per 1m2 of mirror.
Vinyl Backed Mirror
Tapes and adhesives will not adequately adhere to vinyl back mirror and extreme care is needed or the installation will fail. It is recommended that vinyl be carefully removed in the gluing or taping areas so that adhesives are applied directly to the mirror back, or that this method is not used.
Mirrors should never be mounted directly onto untreated surfaces such as concrete block walls, unpainted plaster, plywood, etc. Chemical releases by these surfaces will corrode the mirror. Metal framed mirrors, allowing for circulation of air, have the advantage of protecting the mirror’s edge from direct exposure to elements. In bathroom situations, it is almost always recommended to have mirrors fully framed, even if edge sealing is done.
Mirrocol is recommended for mirror mastic fixing and adheres well to the mirror backing paint and most smooth non porous substrates. For metal and porous substrates such as plastering, concrete, wood, and gypsum, Primer MSP should be used to obtain adhesion.
Black Edge Degradation of Mirror Edges
Mirror is a luxurious sophisticated product combining a film of pure silver with protective overlayers to provide a high quality product for both personal and decorative purposes. The manufacturing process ensures maximum adhesion of the silver coating to the surface of the glass and then applies further overcoatings to protect the silver from degradation. Water or moisture tarnishes silver and is the enemy of mirrors.
This is true with the edge of mirrors, especially when the manufacturing seal has been disturbed by edge working and is exposed to moisture penetration of the silver coating.
Warranties are provided for mirrors but they are void when mirrors are installed in such a way that edges remain wet or condensation is allowed to run down the mirror and accumulate in the glazing channel, pocket or mounting. Such a situation will, in every case, result in the manifestation of black edge and the spreading of the silver tarnish in from the edge.
It is essential that when mirrors are installed in wet areas, such as bathrooms, laundries or other rooms with high moisture or humidity that they are edge sealed, and this can be done after processing or before glazing.
If the mirror is glazed into the mount or channel at installation you must drain or seal the system to prevent water, condensation or moisture penetration to the edge of the mirror where it can remain undetected and damage the mirror.
