Ch.20 Selection of materials, finishes, and furnishings Flashcards
What does MSDS stand for
 material safety data sheets
What are the five groups of the criteria for the selection of materials and finishes
Function, durability, maintainability, safety/health, and cost
These qualities of a material relate to the materials ability to absorb sound or to block the transmission of sound. For most finished materials, sound absorption is the more important criteria and is typically measured in the noise reduction coefficient in our seat. For open plan office design, the articulation class of ceilings may also be important
Acoustic qualities
These criteria are commonly one of the first criteria considered by the designer. However, the appearance of the material must be balanced with all of the other technical and cost criteria. The basic elements and principles of design are related here
Aesthetics
This function of material relates to how easily a product can be obtained and if it can be delivered to the job site in a time to maintain the overall project schedule. Some specialty products can require six months or more to get. Other products are in stock for immediate delivery but may only be available in a limited choice of colors and finishes. Some products, such as furniture, are specifically available in quick ship programs to meet right schedules
Availability
This function of design is related to the color, texture, and other visual characteristics that will vary depending on what manufactures offer. So manufactures or product lines may have a wide range of choice than others, and the fact of anime sway the decision to use a particular company or material
Choice
This function of design is the precise sequence of steps needed to place material or product into the work. Installation methods can affect the cost in scheduling of the material and whether skilled workers will be required or not. In most cases, these for the same types of materials will be very similar. However, some specialty items may require a particular method using factory approved installers
Installation method
This relates to the service ability of the product or material when in use. There are many aspects of durability, and one or more of these may apply to a particular product
Durability
The ability of a material or finish to resist being worn away or to maintain its original appearance when rubbed with another object
Abrasion resistance
Is the method by which one material is connected to another. This criteria can’t have a significant influence on the product selection, depending on the substrate. Some products for materials cannot be attached to other materials we can only be attached with significant expense or effort.
Attachment
The capability of a material to resist adhesion or sticking between two surfaces of a wall covering
Blocking resistance
Refers to below that, when placed on a material, it’s just great enough to break the material.
Breaking strength
In materials resistance to damage, change of finish, or other deleterious changes resulting from exposure to chemicals
Chemical resistance
Refers to the ability of a thin coating, like wall covering her paint, to adhere to its substrate
Coating adhesion
The resistance of coded or decorated surfaces to cracking when they are exposed to low temperatures
Cold cracking resistant
The products resistance to deterioration by a chemical or electro chemical reaction resulting from exposure to moisture, chemicals, or other elements. This is typically a problem when metal products are supposed to moisture
Corrosion resistance
The resistance of a finish to change or loss of color when exposed to light, most commonly the ultraviolet light of the sun
Colorfastness
Materials resistance to the transfer of color from the wall covering surface when rubbed
CRocking resistance
The measure of how will a product is assembled in the factory. Each industry establishes measures of fabrication quality. For example, woodwork is measured according to three great economy, custom, and premium has established by the architectural woodwork Institute
Fabrication quality
The wall coverings resistance to deterioration caused by high temperatures over an extended time
Heat aging resistance
The ability of paint or other finishes to resist loss of color when exposed to sunlight. It is similar to colorfastness
Lightfastness
Materials ability to be cleaned repeatedly with a brush or detergent
Scrub ability
A decrease in dimension when a material is exposed to moisture. This characteristic is most typically applied to fabrics
Shrinkage
Materials resistance to a change in appearance after an application and removal of another material. As with chemical resistance, all products are resistant to some agents more than others, so manufactures literature should be consulted to verify the material is resistant to this agent likely to be present in a particular application
Stain resistant
Is a general criteria referring to the inherent ability of a product to withstand any loads that may be placed on it. This may be as simple as the ability of one part of a detail to support the weight of another part of a detail, or as complex as the ability of a product or detail to stay in the complex gravity and wind loads that may be required a structural engineer to calculate
Strength and structure
The resistance of a thin material, like fabric, to the propagation of an existing tear
Tear resistance or tear strength
The materials ability to be cleaned repeatedly with a sponge and detergent solution, to remove surface dirt
Washability
An important quality for finish materials, products, and details to experience wear and tear through their life cycle of a building. All buildings and interior finishes need to be maintained to preserve their parents and service of life.
Maintainability
The ease with which material can be cleaned using whatever methods are appropriate for that material. For example, carpet must be easy to vacuum, while wall finishes in a restaurant should be easy to wash. Because all materials in all types of buildings get dirty with time, this is one of the most important criteria to consider when selecting finishes
Clean ability
Is a product materials ability to be repaired when damaged. The ability to replace damage components of a finish or detail may also be evaluated by selecting a product. The designer should avoid details that make it difficult are expensive to repair or replace one of the components or parts
Repairability
The materials capacity to recover its own original size and shape after deformation caused by some load. This is typically apply to soft floor covering material, such as vinyl tile, but may also be as important consideration for wallcovering materials
Resilient
Is the materials ability to return to its original configuration after it has been deformed or temporary changed. It is similar to resilience but may apply to any type of product. For example, the holes in a corkboard should be this after pins have been removed
Self healing quality
As a broad term this means meeting the needs and wants of the present generation without harming or compromising the ability of the future generation to meet their needs
Sustainability
Involves the design, operation, and Reeves concepts that together can create functional, healthy, nonpolluting, and environmentally friendly buildings without compromising practical requirements or human comfort. When evaluating products for this, the designer should consider many individual criteria, including recycle continent, recyclability, energy consumption, and lifecycle assessment among others
Sustainable design
Relates to the surface an edge condition of products. They should be not sure projections, edges or surfaces rub and I have to cut or a braid when people come into contact with the product
Finish safety
The likelihood that a material we can bust, is one of the most important criteria for material and finish selection. For most materials, this is related in terms of flames red, smoke developed, and fuel contribution. Most common test developed for this and smoke is the Shriner tunnel test. Other tests are also available and may be required by local building department
Flammability
Is important to prevent the growth of one of these microscopic organisms. Many materials are inherently susceptible to the growth of these materials because they provide an organic nutrients that, when combined with moisture in a suitable temperature, will provide growing medium for the biological contaminants. Most materials can be treated to resist the growth of these materials
Mold and mildew resistance
The release of toxic gas from materials, most commonly after material has been installed. These gases include formaldehyde, chlorofluorocarbons CFCs, and other listed on the EPA’s list of hazardous substances. This is one of the most important components of indoor air quality
Outgassing
Providing protective protection against theft, vandalism, intentional physical harm, or a combination of all three. Insecurity is an important aspect of design, material and product selection can be evaluated in these terms. Doors, glazing, and hardware are common products that are available with various levels of security.
Security
The ability of a foreign material to help prevent accidental sleeping. It is commonly measured with the coefficient of friction cOF. Are they both the IVC and the ADA require going to be this, there are no specific requirements of the COF of any other measure.
Slip resistance
This results when chemicals that contain carbon and hydrogen vaporize at room temperature and pressure. These are found in mini indoor sources such as paint, feelings, and carpeting. When select materials, it’s constant of this must be limited to be applicable standards
Volatile organic compound VOC emission
What are the two aspects of cost of a material
First cost and lifecycle cost
The initial amount of money required to purchase and install the product
First cost
The entire cost of a product over his life or the life of the building and includes the initial cost, maintenance, energy cards, financing calls, and replacement costs
Lifecycle cost
Failure do you scare ordinarily exercised in similar cases by other qualified members of the profession and the failure to use reasonable diligence and best professional judgment in the exercise of work
Negligence
Describes freestanding interior components that are not physically attached to the construction and that are usually purchased under separate contract.
Furniture, fixtures, and equipment FF&E
What are the three basic categories of furniture
Ready-made, custom design, and built in
Purchased from a selection of standard products of a particular manufacturer. The specify are usually has some choice of fabric types, fabric colors, and wood finishes, but the selection is limited to what is available on the market. Even with these limitations, there are thousands of possible variations of styles, furniture type, cost range, and quality from which to choose.
Ready-made furniture
