2. INTRODUCTION
GLAZING, which derives from the middle
English for ‘GLASS’, is a part of a window
or a wall made up of glass. It can be
mounted on a window sash or door stile,
made of wood, aluminum, or PVC. It is
commonly used in low temperature solar
thermal collectors because it helps to
retain the collected heat.

3. TYPES OF
GLAZINGS
Glazing is mainly divided into 2 types-
a. PRIMARY GLAZING
i. Structural Glazing
ii. Curtain Glazing
b. SECONDARY GLAZING

4. PRIMARY GLAZING
Common types of glazing that are used in
architectural applications include clear and
tinted float glass, tempered glass, and
laminated glass.
ordinary clear glass has a slight green tinge
but special clear glasses are offered by
several manufacturers.

5. STRUCTURAL GLAZING
These are fabricated from roll formed sections made of
galvanized color coated steel with zinc phosphate. Silicon
will be applied to arrest water leakages. These are
generally used in high rise buildings to improve the
aesthetics.
Features-
a. It provide safety from air and water infiltration.
b. Durability
c. Dimensional accuracy

7. CURTAIN GLAZING
These are fabricated from roll formed
sections made of galvanized color coated
steel with a zinc phosphate, nylon or high
grade aluminum with powder coating.
Required stiffeners will be inserted to take
care of wind loads.

9. SECONDARY GLAZING
This generally involves fitting a second
sheet of glass or plastic to a window
frame. Installers can insert a separate
aluminium frame and glass panels around
the existing window, but this is the more
expensive option.
For a cheap option, try a plastic film fitted
to the actual glass.

10. KEY POINTS -
- For timber thickness of 28 mm, single or primary
glazed windows are standard.
- For timber thickness of 34 mm, double or
secondary glazed windows are standard.
- Secondary glazing is the most effective
alternative to double glazing and can be done
professionally.
- It can be fitted as a separate pane of glass or as
a film stuck to the existing window pane
- There are other ways to save heat and energy,
such as draught exclusion.

11. GLAZING MATERIALS
The most common types of glazing materials are
glass, polycarbonate (PC), polyethylene (PE)
films.
The R-value of glass is 0.8
PC generally comes in twin or triple wall sheets in
thickness of 4-16 mm. Twin wall PC has R-value
of 1.4 while for triple wall it is 2.5. It lasts for 10-20
years.
Single layer PE films has R-value of 0.8 while for
double layer it is 1.4

12. ADVANCES IN GLAZING
MATERIALS FOR WINDOW
Research and Development into types of
glazing have created a new generation of
materials that offer improved window
efficiency and performance. Advanced
glazing have increased windows R-value.

13. If a window’s R-value is high, it will lose less heat
than one with a lower R-value .
When comparing different windows you should
ensure that all R-value listed by manufacturers-
a. are calculated for the entire window, including
the frame and not just for the center of the glass.
b. Represent the same size and style of window.

14. No one type of glazing is suitable for every
application. Many materials are available that
serve different purposes. You may discover that
they need 2 types of glazing for a home because
of the directions that the windows face and the
local climate.
You should first examine their heating and cooling
needs and prioritize desired features such as day
lighting, solar heating, shading, and ventilation.
