A decorative and highly transparent glass that adds distinction to windows and to store fronts
|  | 
JR Central Towers (Nagoya) |
| Float glass is a monolithic, highly transparent glass that brings a combination of function and beauty to both architectural applications and specialty uses. Its inherent advantages spring from the unique manufacturing process of floating molten glass on molten tin. |  |
 |
 |
Precise flatness |
|
Its precise flatness gives the glass a high degree of
transparency. |
 |
Natural lighting |
|
The smooth surface permits natural light to flow into
a room. |
 |
Maximum size and thickness |
|
Float glass fully meets requirements for large glazed
openings. It is available in maximum width and maximum length as shown
below.
Should the desired dimensions exceed sizes stated in this catalog,
consult Central Glass or an authorized representative. |
 |
 | High-rise buildings, store interiors and exteriors, houses and greenhouses |
 | Decorative glass material |
 | Glass panels and screens |
 | Showcases and other displays |
 |
 |
Maintain an ample distance between the surface of the
glass and thick curtains, shades, lockers, etc. |
 |
The glass surface should not be painted or coated with
paper. |
 |
Calculate and carefully consider thermal values to avoid
thermal cracking when a shading or decorative film is put on the glass
surface. |
 |
Cut the edges of glass cleanly. |
 |
Use a sander of #120 mesh or above to smooth and correct
cut edges. A rough sander may damage the edges of the glass. |
 | Warning labels --- such as "Glass: Handle with Care" ---can damage the surface of the glass if glued with an organic adhesive. Use a rubber-base adhesive agent or an appropriate type of masking tape. |
 | Epoxy resin coatings can damage the surface of the glass. Coating work near the glass should be performed only after the glazed openings have been completely covered. |
 | The adhesive agent should be either a silicone sealant or a high modulus sealing compound. |
 | Epoxy resin agents should not be used. They tend to harden too quickly and can damage the surface of the glass. |
 |
 |
Carefully set glass units in sashes and ensure that
the edge clearance is correct. Wind pressure can cause glass units
to fall out if the setting is incorrect. |
 |
Provide a sufficient clearance for the edges of glass
units to prevent deformation under the forces generated by earthquakes,
opening or closing impact and irregular thermal stress. |
 |
Use a high quality elastic sealing compound (silicone
or polysulfide). |
 |
Use polyethylene foam or chloroprene rubber as a backup
material. |
 |
Provide setting blocks of chloroprene
rubber (90° hardness) at two places along the bottom edge. |
