Float glass – Manufactured by pouring molten glass onto a surface of molten tin and allowing it too cool slowly. The resulting flat, parallel surfaces minimize distortion and eliminate the need for grinding and polishing. Float glass is the successor to plate glass and accounts for the majority of flat-glass production.
Sheet – Fabricated by drawing the molten glass from a furnace (drawn glass), or by forming a cylinder, dividing it lengthwise, and flattening it (cylinder glass). The fire polished surfaces are not perfectly parallel, resulting in some distortion of vision. To minimize this distortion, glass should be glazed wit the wave distortion running horizontally.
Glass with no distortions a. Sheet Glass
b. Float Glass
c. Tempered Glass d. Plate Glass
Tempered – Annealed glass that is reheated to just below the softening point and then rapidly cooled to induct compressive stresses in the interior. Tempered glass has three to five times the resistance of annealed glass to impact and thermal stresses but cannot be altered after fabrication. When fractured, it breaks into relatively harmless pebble-sized particles.
Annealed glass – is cooled slowly to relieve internal stresses
Heat-strength glass – is annealed glass that is partially tempered by a process of reheating and sudden cooling. Heat-strengthened glass has about twice the strength of annealed glass of the same thickness.
Plate glass – formed by rolling molten glass into a plate that is subsequently ground and polished after cooling. Plate glass provides virtually clear, undistorted vision.

a. Tempered Glass b. Clear Glass
c. Glass Blocks
Note: We noticed that many students (now new architects) answered “glass blocks.” We don’t know how the PRBoA answered this but the correct answer is called Laminated “Structural” Glass in the construction and is the same one being employed in several high-rise viewing platforms like the ones in the Sears Tower Sky Deck. Although Glass Blocks can be used too, it will not give a clear view of the ground floor.
Type of Glass wherein you can see the people inside the building during night time
a. Tinted Glass
b. Reflected Glass c. Tempered Glass d. Insulated Glass
Study tinted glass, its uses etc.
When multiple glass panels or “lites” are assembled into units, they are commonly referred to as insulated glass, double glazing, Double Glazed Units (UK and Europe) or insulating Glass Units (IGU) (North America and Australia).
These units use the thermal and acoustic insulating properties of a gas (or vacuum) contained in the space formed by the unit. They can provide good insulation without sacrificing transparency (visual transmittance, VT). Single glazed tinted and reflective glasses can provide similar thermal insulation, but for the same insulation performance are harder to see through and provide little protection against unwanted sound.
Most IGUs are double glazed, but IGUs with three sheets or more, i.e. “triple glazing” are becoming more common due to higher energy costs. Insulated glazing may be framed in a sash, frame or in a curtain wall.

Advantage of an Aluminum Door over a Wooden Door
Turnstile - also called a baffle gate, is a
form of gate which allows one person to pass at a time. It can also be made so as to enforce one-way traffic of people, and in addition, it can restrict passage only to people who insert a coin, a ticket, a pass, or similar. Thus a turnstile can be used in the case of paid access (sometimes called a fare
gate when used for this purpose), for
example public transport as a ticket barrier or a pay toilet, or to restrict access to authorized people, for example in the lobby of an office building.
