Glass And Glazing Quiz Questions

When you are inside a structure using reflective glass at night, you can see yourself. Reflective glass works by reflecting light, so when it is dark outside and there is light inside the structure, the glass will reflect your image back to you. This allows you to see yourself when you are inside the structure at night.

To minimize the nuisance caused by the busy and heavy traffic main road, installing double glazing windows would be the most effective solution. Double glazing windows have two layers of glass with a gap in between, which helps to reduce noise transmission from outside. This would significantly decrease the noise levels on the upper floors of the high-end residential building, providing a more peaceful and comfortable living environment.

Diamond is used to cut glass because it is the hardest known substance. Its hardness allows it to create a clean, precise cut on glass without shattering or damaging it. Other materials like sharp stone, wire, or snapper would not be able to effectively cut glass without causing it to break or crack.

Reflective glass is the correct answer because it has the unique property of being translucent in the morning, allowing light to pass through, but at night, when viewed from inside the building, it acts like a mirror and reflects the light back. This is achieved through the application of a reflective coating on the surface of the glass, which gives it the ability to reflect light and create a mirror-like effect.

Insulated glass typically consists of two or more glass panes separated by a spacer and sealed together. The space between the glass panes is filled with dry air, which acts as an insulating layer. This dry air helps to reduce heat transfer and improve the energy efficiency of the glass. PVC, PBV, and weather strip are not typically found inside insulated glass.

Electrochromic glass is a type of glass that can change its transparency when an electric current is applied. It is also known as switchable glass because it can switch between being transparent and opaque. This type of glass is commonly used in smart windows, where it allows for control over the amount of light and heat that enters a building. Electrochromic glass is different from chromogenic, thermochromic, and photochromic glass, which change their properties in response to other stimuli such as temperature or light.

The correct answer is fritted glass. Fritted glass is a type of glass that has been treated with a ceramic material called frit, which is applied to the surface and then fused to the glass through a heating process. This creates a textured or patterned appearance on the glass, providing privacy and diffusing light. The photo likely shows a glass surface with a textured or patterned appearance, indicating that it is fritted glass.

Pattern glass is the correct answer because an etching glass refers to a type of glass that has a pattern or design etched onto its surface. This pattern can be created using various techniques such as sandblasting or acid etching. Colored glass refers to glass that has been tinted or stained with different colors, plate glass refers to a type of flat glass that is commonly used in windows and mirrors, and flat glass simply refers to any type of glass that has a flat surface.

When someone tries to break a laminated glass, it will break but not splinter. Laminated glass is made by sandwiching a layer of plastic between two layers of glass, creating a strong and durable material. When force is applied to it, the glass may crack or shatter, but the plastic layer holds the broken pieces together, preventing them from splintering and causing potential harm. This makes laminated glass a safer option as compared to regular glass, especially in situations where the risk of injury from shattered glass is high.

Insulated glass is separated by gaps that are spaced with sealant and fully filled with air. This design helps to provide insulation and reduce heat transfer between the two glass layers. The sealant ensures that the gaps are completely filled, preventing air leakage and maintaining the insulating properties of the glass. By using air as the insulating medium, the glass can effectively reduce heat loss or gain, making it more energy-efficient for buildings.

Mirror glass is the correct answer because it has a thin silver-based coating on its backside, which gives it its reflective properties. The silver coating is then protected from corrosion by a layer of copper. This combination of silver and copper allows the mirror glass to reflect light and create a clear reflection.

When tempered glass breaks, it shatters into small, granular pieces instead of large, sharp shards. This is due to the unique manufacturing process of tempering, which involves heating the glass and then rapidly cooling it. This process creates internal stress within the glass, making it stronger and more resistant to breakage. When the glass does break, the stress causes it to break into small, relatively harmless pieces, reducing the risk of injury.

Silica is one of the primary components of glass. It is a naturally occurring compound found in sand and is the main ingredient used in the production of glass. Silica has a high melting point and when heated, it becomes molten and can be molded into various shapes to form glass. It provides strength and durability to the glass and also helps to make it transparent. Therefore, silica is an essential component in the manufacturing of glass.

Wired glass is a type of glass that is commonly used for fire exits. It is made by embedding a wire mesh within the glass during the manufacturing process. This wire mesh helps to hold the glass together in case of breakage, preventing it from shattering into large, dangerous shards. This makes wired glass a safer option for fire exits as it reduces the risk of injury during an emergency evacuation.

The correct answer is patterned glass. This type of glass is characterized by having decorative patterns or designs on its surface. It is often used for privacy purposes as it allows light to pass through while obscuring the view. The image shown above likely displays a piece of patterned glass with a specific design or pattern on it.

Low-E coatings are a type of metallic coating that is ultra thin, virtually transparent, and almost colorless. These coatings have the ability to selectively reflect solar radiation of different wavelengths. This means that they can reflect a significant amount of heat and infrared radiation while allowing visible light to pass through. This property makes Low-E coatings highly effective in reducing heat transfer and improving energy efficiency in buildings and windows. They are commonly used in windows and glass panels to minimize heat gain during hot weather and heat loss during cold weather.

Glass etching refers to the technique of creating art on the surface of glass by applying acidic, caustic, or abrasive substances. Traditionally, this was done after the glass was blown or cast.

Float glass is a type of glass that is made by floating molten glass on a bed of molten metal, usually tin. This process allows the glass to have a smooth and flat surface, resulting in minimal distortions. Unlike other types of glass, such as sheet, laminated, or insulated glass, float glass does not have any additional layers or coatings that may cause distortions. Therefore, float glass is the correct answer as it is known for its superior clarity and lack of distortions.

Float glass is the correct answer because it is a type of glass that is commonly used in mirrors to achieve a distortion-free surface. Float glass is made by floating molten glass on a bed of molten metal, typically tin, which results in a smooth and flat surface. This process eliminates any imperfections or distortions in the glass, making it ideal for mirror applications where a clear reflection is desired. Plate glass, pattern glass, and wired glass are not specifically designed for distortion-free mirrors.

The correct answer is titanium oxide coating. Titanium oxide coating is a type of coating used on self-cleaning glass that acts as a catalyst. This coating enables sunlight to convert dirt on the glass surface into carbon dioxide and water, effectively cleaning the glass.

Using a heavy drapes curtain with a curtain wall to block sun heat is not ideal. Instead, it is recommended to use a mechanical horizontal rolling shade. This type of shade is more effective in controlling the amount of sunlight and heat that enters the space. The heavy drapes curtain may not provide sufficient insulation against the sun's heat, whereas the rolling shade can be adjusted to block or allow sunlight as needed.

A glass that can withstand high compression on its outer fiber and tension at the center would be described as "high resistant to breakage." This means that the glass is strong and durable, able to withstand external forces and pressure without breaking or shattering easily. It implies that the glass has a high level of resistance to damage or breakage, making it a reliable and long-lasting material.

Insulated glass is the correct answer because it is commonly used in glass curtain walls. It consists of two or more glass panes separated by an air or gas-filled space, providing better insulation and energy efficiency compared to other types of glass. This helps in reducing heat transfer and noise transmission, making it suitable for exterior applications. The given options of 20mm thick solid glass, tinted glass, and fritted glass do not specifically mention any insulation properties, making them less likely to be the correct answer.

Laminated glass is ideal for skylights because it is made up of two or more layers of glass with a layer of plastic in between. This construction makes it strong and resistant to shattering, providing safety in case of breakage. The plastic layer also helps to block harmful UV rays, reducing the amount of heat and glare that enters the space. Additionally, laminated glass provides sound insulation, making it a suitable choice for skylights in noisy areas. Therefore, laminated glass is the preferred type for skylights due to its strength, safety features, UV protection, and soundproofing properties.

Reflective glass is the correct answer because it is a type of glass that has a reflective coating on its surface, allowing it to reflect light and reduce the amount of heat that enters a building. This reflective coating also provides privacy during the night as it prevents people from seeing the interior walls of the building from the outside.

The best window U-value is .20 or less. U-value measures the rate of heat transfer through a window, with lower values indicating better insulation. Therefore, a U-value of .20 or less means that the window has excellent insulation properties and is highly efficient in preventing heat loss or gain.

Float glass is dust-free because it is manufactured using a process called the float glass method, where molten glass is poured onto a bed of molten tin, allowing it to float and form a smooth, flat surface. This process eliminates the need for grinding or polishing, resulting in a dust-free glass.

Le Corbusier did not use the color blue for the Ronchamp Church design. The question states that the glass in the openings of the church is often decorated with small pieces of stained glass in typical Corbusier colors. Since blue is not mentioned as one of his typical colors, it can be inferred that he did not use blue for this project.

Tempered glass is the correct answer because it is a type of glass that is specifically designed for safety purposes. It undergoes a special heating and cooling process that makes it stronger and more resistant to breakage compared to regular glass. Tempered glass is commonly used in shop displays because it is clear and provides a transparent view of the products while also ensuring that it is less likely to shatter into sharp, dangerous pieces if it does break.

The R-value is a measure of the thermal resistance of a material, commonly used in the building industry. It indicates how well a material can resist the flow of heat through it. A higher R-value means better insulation and less heat transfer. It is an important factor to consider when choosing insulation materials for buildings to ensure energy efficiency and comfort.

Glass surfaces are numbered for specifications with the exterior surface being labeled as number 1 and the interior surface being labeled as number 2.

Thermo chromic glass is a type of glass that darkens when exposed to heat from the sun. This glass contains materials that undergo a reversible change in color or transparency when there is a change in temperature. When the glass is heated, the molecules in the material rearrange, causing the glass to darken. As the temperature decreases, the glass returns to its original transparent state. Thermo chromic glass is commonly used in windows and eyewear to regulate the amount of sunlight and heat entering a space.

Patterned glass is a type of glass that is used when light is required but obscure vision for privacy. It has a textured or patterned surface that distorts the view, making it difficult to see through clearly. This type of glass is commonly used in windows, doors, and partitions where privacy is desired, such as in bathrooms or conference rooms. The patterns on the glass can vary, offering different levels of privacy while still allowing light to pass through.

Photochromic glass is a type of glass that darkens when exposed to sunlight. It contains special compounds that undergo a chemical reaction when exposed to ultraviolet (UV) light, causing the glass to darken. This reaction is reversible, meaning that when the glass is no longer exposed to UV light, it gradually returns to its clear state. Photochromic glass is commonly used in sunglasses and windows to provide protection from bright sunlight and reduce glare.

The U-value is a measurement of how quickly heat conducts through the entire window assembly and frame. It represents the overall thermal conductivity of the window, taking into account factors such as the glass, frame, and any insulating materials. A lower U-value indicates better insulation and less heat loss, making it an important factor to consider when evaluating the energy efficiency of windows.

Chromogenic glass is a type of glass that changes its optical properties in response to external stimuli such as temperature, light, or electrical current. This means that it can alter its color, transparency, or reflectivity based on the conditions it is exposed to. This ability makes chromogenic glass useful in various applications, including smart windows, privacy glass, and architectural designs where adaptive optical properties are desired.

Corrugated thermoplastic is used in greenhouses because it is a lightweight and durable material that allows for the transmission of sunlight. It is also cost-effective and easy to install. The corrugated design of the material helps to distribute light evenly throughout the greenhouse, promoting healthy plant growth. Additionally, thermoplastic is resistant to UV rays and can withstand extreme temperatures, making it an ideal choice for greenhouse construction.

Sheet glass has the waviest face compared to the other types of glass mentioned. This is because sheet glass is produced by pouring molten glass onto a flat surface and then rolling it into a sheet, resulting in a wavy texture on one side. Float glass, on the other hand, is made by floating molten glass on a bed of molten metal, resulting in a smooth and flat surface. Corrugated glass and glass blocks also do not have the wavy texture that sheet glass has.

The correct answer is PV, which stands for photovoltaic. Photovoltaic refers to the technology that converts sunlight into electricity using solar cells. In the given context, the special glass design incorporates solar cells, allowing it to generate power from sunlight. Therefore, PV is the appropriate term to describe this glass.

The U-Factor is a measure of the rate of heat transfer through a material or assembly. It indicates how well a glazing system can prevent heat from escaping or entering a building. A lower U-Factor means better insulation and higher energy efficiency. Therefore, the performance of glazing as a thermal insulator can be determined by its U-Factor.
