Glass Replacement |

Patio door glass can be either single
glazed or dual glazed. Most homes built within the past
10 years will have dual-glazed units.
Most manufacturers of patio door units use a standard
glass size but unfortunately not all are using the same
thickness of glass or the same overall thickness of the
unit. Most of the dual-glazed units are 5/8" thick but
some manufacturers use 1/8" glass while others may use
3/16" glass. Generally speaking, the thicker the dead
air space between the panes of glass, the better the
insulation factor.
Replacing the glass in a patio door is usually a job
that is best left for the professionals but Clifton Park
Glass & Mirrors will assist anyone who wishes to tackle
it themselves. If you can remove the patio door panel
from the opening, bring it into to our shop and we'll be
glad to advise the proper size and thickness of glass
that you need.
There is one other requirement about patio door glass
that differs from regular window glass: safety glazing
codes apply. Usually the glass used in patio door is
safety tempered. Once the raw sheet of glass has been
tempered, it can no longer be cut thus the reason for
the manufacturers settling in on "standard" sizes. |

Some
common sizes are 34" x 76" (for a 3 foot panel) and
46" x 76" (for a 4 foot panel). Custom sizes are
available.
Glass that has a tinted color or internal grids is
always a special order. We do recommend that if the
glass in the sliding panel portion is being
replaced, then a close inspection of the rollers at
the bottom is necessary. If there is any noticeable
wear or noise, then now is the most economical time
to replace them.
Every manufacturer has their own design of rollers,
handles, and locks. There is no such thing as a
"standard" design of hardware. Most roller units can
be replaced for a minor fee.
