About Decorative Columns — An Overview

Gone are the days when decorative columns were used to enhance the architectural beauty of palaces. Nowadays, they are extensively used in residential and commercial buildings to add a touch of class and elegance. They lend strength to a structure and make it aesthetically beautiful. They are also used to divide areas. You can use columns in a long hallway to mark different areas without wasting space.

Decorative columns are available in different types of materials and styles. Some of the materials used for columns are polyurethane, wood, fiberglass, plaster, and aluminum. Among styles, Roman & Greek columns are the preferred ones.

Greek Decorative Columns:
As the name implies, these columns are inspired from the Greek architecture. There are three types of decorative columns in Greek architecture.

Doric:
This is considered to be the oldest styles of columns that originated in 600 BC in western Greece. This is the simplest style of columns. It does not have a base and its shaft consists of twenty flutes or grooves that run from the bottom to the top. Just above the neck of the column, there is a convex or bowl-shaped echinus and above it, lies a flat abacus. Usually, the height of this type of column is eight times its diameter.

Ionic:
This style originated in 400 BC in eastern Greece. The Ionic column is more decorative than the Doric column. It consists of a round base, the shaft is slender than the one in a Doric column, and its capital has volutes or scrolls.

Corinthian:
The Corinthian Column is the most stylish and decorative of the Greek columns. Apart from volutes or scrolls, the capital consists of carvings of flowers and acanthus leaves. Its shaft is narrower than the ones in the Ionic columns. The height of the column is ten times its diameter.

Roman Columns:
Roman architecture widely uses various variations of Greek decorative columns. They also have their own unique and distinct column styles – Tuscan and Composite.

Tuscan:
This is considered to be an adaptation of the Doric column style. However, the Tuscan Column much simpler than the Doric column and consists of a simple shaft and capital. The shaft is often unfluted and the base is missing.

Composite:
This style is inspired from both the Ionic column and the Corinthian column. It consists of scrolls and carvings of flowers and leaves.

While choosing decorative columns, it is important to keep the purpose of installing them in mind. This will help you decide the material, dimensions, and load bearing capacity of the column. If you want a column for decorative purposes, like for holding vases or lights, then any column that goes well with the décor of the place would serve the purpose. But, if you want the column to support a structure, you should consult an architect.

The choice of material should also depend on the area where you want to install the column. For example, if you want a column for the garden area, you should use fiberglass columns that can withstand different elements of nature.

Buying decorative columns has become quite easy with the presence of online stores. Not only do they have a huge variety of columns, but they also offer them at competitive rates.

PU Moulding Installation

Polyurethane Installation

Polyurethane mouldings/cornices may be installed much the same way you would install wood mouldings.

For a better fit, it is advised that a flat or Butt Joint is used to join longer lengths of polyurethane mouldings. Cut all pieces 1/8th of an inch longer than the required measurement, fitting the ends in place first and the middle sections last.

Always place a continuous bead of premium polyurethane adhesive along all adjoining wall and ceiling surfaces before final positioning of the moulding. Poly-glue is essential when attaching one length of moulding to the next. A pneumatic pin nailer works well for fastening polyurethane mouldings to wall and ceiling surfaces; alternatively, trim head drywall screws or finishing nails may be used.

Corner Blocks

Corner or center blocks may be used to avoid difficult or challenging mitre cuts. When using corner or adjoining center blocks, be sure to mount the blocks to the wall and ceiling prior to measuring and cutting moulding lengths.

Filling and Sanding

Once all of the mouldings are fixed in place, fill any joints or remaining voids with a paintable siliconized latex caulking. This same caulking may be applied sparingly along the top and bottom edges of the moulding where it meets the ceiling and wall. A damp cloth or silicone coving tool may be used to clear away any excess caulking to leave a clean professional look.

Any remaining nail or screw holes may be filled with sandable, paintable non-shrinking filler. Be careful not to over sand the surfaces of your polyurethane mouldings. Sanding past the protective barrier undercoating may necessitate further filling and sanding to maintain a paintable surface.

Ceiling Medallions

Place a solid bead of premium adhesive around and about the backside of the medallion. Pressing the medallion into place, it may then be secured with 4 trim head dry wall screws. Be sure to place the screws so that any holes created may be filled and sanded with minimal effort.































Wall Niches

Some surface mount wall niches may be hung temporarily using attached hardware or permanently using the same applicator procedures as for Ceiling Medallions. Other niches available come complete with their own template and installation instructions.

A system to better protect water bodies

The Central Leading Group for Comprehensively Deepening Reforms approved a document on Dec 11 last year to implement the river chief system across the country by the end of 2018. The river chief system is aimed at promoting better coordination among government departments to protect the country's water bodies.

It is just one example of President Xi Jinping's environmental protection and eco-civilization philosophy.

China has a long history of water control and management. In ancient times, the administrators appointed special officials in charge of river affairs. During the Warring States Period (475-221 BC) governor of Shu prefecture Li Bing, ordered the building of the Dujiangyan Irrigation System in today's Sichuan province in Southwest China, which is a famous example of water conservancy and could be regarded as the precursor of the river chief system.

Difference Between Polystyrene & Polyurethane

Both polystyrene and polyurethane are polymers, synthetic substances made from long chains of molecules. These molecules consist mostly of carbon and hydrogen atoms. Industry produces these ubiquitous plastic building materials to make all sorts of common items. The computers we use are typically encased in polystyrene, which is an older polymer. However, polyurethane is increasingly coming to replace polystyrene in certain situations, particularly those which require more flexibility. Though they are sometime confused, there are differences between the two in terms of their composition, the ability of finished products to resist chemicals and conduct heat and their tolerance for thickness.

Composition

• Polystyrene is a polymer containing molecules composed of carbon and hydrogen atoms, typically eight of each. The molecular formula of polyurethane, on the other hand, describes a much more complex polymer made from molecules composed of nitrogen and oxygen as well as carbon and hydrogen. Unlike polystyrene, which forms a hard plastic, polyurethane's polymers can be arranged differently to create substances with varying degrees of flexibility.
• 
  

R-Value

• The R-value of a building material measures its thermal resistance. Polyurethane demonstrates about twice the resistance to heat that polystyrene manages and is an excellent material for electrical insulation. In addition, polyurethane continues to maintain flexibility in very cold conditions, though a gradual stiffening begins at 0 degrees Fahrenheit. However, this resistance varies according to the density and thickness of each material.
• 
  

Fire Resistance

• Polyurethane does not melt, unlike polystyrene. In fact, polyurethane will remain mostly undamaged by heat until temperatures reach 700 degrees, at which point the material begins to char. Polystyrene will melt at temperatures in the 200- to 300-degree range. Polyurethane makes a superior fire-retardant material.
• 
  

Chemical Resistance, Weathering And Abrasion

• While polystyrene will suffer when subjected to solvents such as gasoline and certain insect sprays, polyurethane is resistant to all chemicals. This polymer also outperforms polystyrene in resisting atmospheric damage due to oxidation and sunlight. In fact, polyurethane withstands all physical attacks and stresses better than polystyrene.
• 
  

Load Bearing

• Since polyurethane resembles rubber as well as plastic, it can be effectively used to make load-bearing wheels, mechanical joints, couplings and machine mounts. Polystyrene does not have the flexibility for these tasks.
• 
  

Noise Abatement

• Since it has some of the qualities of rubber, polyurethane is useful in achieving mechanical sound reduction. Gears made from this polymer make much less noise.

Introduction to Polyurethanes: Polyurethane Applications

Heating and cooling costs amount to about 56 percent of the energy used in the average American home, according to the U.S. Department of Energy. The nature of the chemistry allows polyurethanes to be adapted to solve challenging problems, to be molded into unusual shapes and to enhance industrial and consumer products.

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications.

Types of Polyurethane:

Flexible Polyurethane Foam 

Flexible polyurethane foam is used as cushioning for a variety of consumer and commercial products, including bedding, furniture, automotive interiors, carpet underlay and packaging. Flexible foam can be created in almost any variety of shapes and firmness. It is light, durable, supportive and comfortable.

Flexible polyurethane foam accounts for about 30 percent of the entire North American polyurethane market, and is used largely for bedding, furniture and in the automotive industry.

Rigid Polyurethane Foam 

Rigid polyurethane and polyisocyanurate (polyiso) foams create one of the world's most popular, energy-efficient and versatile insulations. These foams can significantly cut energy costs while making commercial and residential properties more efficient and comfortable.

According to the U.S. Department of Energy, heating and cooling account for about 56 percent of the energy use in a typical U.S. home, making it the largest energy expense for most homes. To maintain uniform temperature and lower noise levels in homes and commercial properties, builders turn to rigid polyurethane and polyisocyanurate foam. These foams are effective insulation materials that can be used in roof and wall insulation, insulated windows, doors and air barrier sealants.

Coatings, Adhesives, Sealants and Elastomers (CASE) 

The uses of polyurethanes in the coatings, adhesives, sealants and elastomers (CASE) market offer a broad and growing spectrum of applications and benefits. Polyurethane coatings can enhance a product’s appearance and lengthen its lifespan. Polyurethane adhesives can provide strong bonding advantages, while polyurethane sealants provide tighter seals. Polyurethane elastomers can be molded into almost any shape, are lighter than metal, offer superior stress recovery and can be resistant to many environmental factors.

Thermoplastic polyurethane (TPU) 

Thermoplastic polyurethane (TPU) offers a myriad of physical property combinations and processing applications. It is highly elastic, flexible and resistant to abrasion, impact and weather. TPUs can be colored or fabricated in a wide variety of methods and their use can increase a product's overall durability.

TPU is an elastomer that is fully thermoplastic. Like all thermoplastic elastomers, TPU is elastic and melt-processable. In addition, it can be processed on extrusion, injection, blow and compression molding equipment. It can be vacuum-formed or solution-coated and is well suited for a wide variety of fabrication methodologies. TPU can provide a considerable number of physical property combinations, making it an extremely flexible material adaptable to dozens of uses such as construction, automotive and footwear.

Reaction Injection Molding (RIM) 

Car bumpers, electrical housing panels and computer and telecommunication equipment enclosures are some of the parts produced with polyurethanes using reaction injection molding (RIM). Adding design flexibility, the polyurethane RIM process produces parts that are usually not achievable using typical injection molding processes, such as thick- and thin-walled parts, encapsulated inners and foamed cores. In addition to high strength and low weight, polyurethane RIM parts can exhibit heat resistance, thermal insulation, dimensional stability and a high level of dynamic properties. Automotive, construction, appliance, furniture and recreation and sporting goods are a few of the markets and applications using RIM technology.

Binders 

Polyurethane binders are used to adhere numerous types of particles and fibers to each other. Their primary areas of use are in the manufacturing of wood panels, rubber or elastomeric flooring surfaces and sand casting for the foundry industry. The highest volume application for polyurethane binders is in the manufacture of Oriented Strand Board (OSB). These wood panels are used in structural sheathing and flooring, manufactured housing, joists and beams and shop panels. Rebond carpet underlay uses polyurethane binders to adhere scrap pieces of foam, which are often flexible polyurethane foam, together in its production.

Waterborne Polyurethane Dispersions (PUDs) 

Waterborne polyurethane dispersions (PUDs) are coatings and adhesives that use water as the primary solvent. With increasing federal regulation on the amount of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) that can be emitted into the atmosphere, PUDs are being used in more industrial and commercial applications.

Applications for Polyurethane:

Apparel 

When scientists discovered that polyurethanes could be made into fine threads, they were combined with nylon to make more lightweight, stretchable garments. Over the years, polyurethanes have been improved and developed into spandex fibers, polyurethane coatings and thermoplastic elastomers.

Because of today’s advances in polyurethane techniques, manufacturers can make a broad range of polyurethane apparel from man-made skins and leathers used for garments, sports clothes and a variety of accessories.

Appliances 

Polyurethanes are an important component in major appliances that consumers use every day. The most common use for polyurethanes in major appliances is rigid foams for refrigerator and freezer thermal insulation systems. Rigid polyurethane foam is an essential and cost-effective material that can be used for meeting required energy ratings in consumer refrigerators and freezers. The good thermal insulating properties of rigid polyurethane foams result from the combination of a fine, closed-cell foam structure and cell gases that resist heat transfer.

Automotive 

Polyurethanes are used throughout cars. In addition to the foam that makes car seats comfortable, bumpers, interior “headline” ceiling sections, the car body, spoilers, doors and windows all use polyurethanes. Polyurethane also enables manufacturers to provide drivers and passengers significantly more automobile “mileage” by reducing weight and increasing fuel economy, comfort, corrosion resistance, insulation and sound absorption.

Building and Construction 

Today's homes demand high-performance materials that are strong, yet lightweight; perform well, yet are easily installed; and are durable, but also versatile. Polyurethane helps conserve natural resources and helps preserve the environment by reducing energy usage. With its excellent strength-to-weight ratio, insulation properties, durability and versatility, polyurethane is frequently used in building and construction applications. Both the affordability of these versatile materials and the comfort they provide homeowners have made polyurethane components part of homes everywhere.

Polyurethane is used all over the house. In floors, flexible foam padding cushions your carpet. In the roof, reflective plastic coverings over polyurethane foam can bounce sunlight and heat away, helping the house stay cool while helping reduce energy consumption. Polyurethane building materials add design flexibility to new homes and remodeling projects. Foam-core panels offer a wide variety of colors and profiles for walls and roofs, while foam-cored entry doors and garage doors are available in different finishes and styles.

Composite Wood 

Polyurethanes play a major role in modern materials, such as composite wood. Polyurethane-based binders are used in composite wood products to permanently glue organic materials into oriented strand board, medium-density fiberboard, long-strand lumber, laminated-veneer lumber and even strawboard and particleboard.

Electronics 

Often referred to as “potting compounds,” non-foam polyurethanes are frequently used in the electrical and electronics industries to encapsulate, seal and insulate fragile, pressure-sensitive, microelectronic components, underwater cables and printed circuit boards.

Polyurethane potting compounds are specially formulated by developers to meet a diverse range of physical, thermal and electrical properties. They can protect electronics by providing excellent dielectric and adhesive properties, as well as exceptional solvent, water and extreme temperature resistance.

Flooring 

Either as a foam underlay or on top as a coating, polyurethanes can make the floors we walk on every day more durable, easier to maintain and more aesthetically pleasing. Using flexible polyurethane foam as a carpet underlay in residential or commercial applications can significantly increase the lifespan of the carpet, protect its appearance, provide added comfort and support and can reduce ambient noise.

Polyurethanes are also used to coat floors, from wood and parquet to cement. This protective finish is resistant to abrasion and solvents, and is easy to clean and maintain. With a polyurethane finish, a new wood, parquet or cement floor wears better and longer, while an old floor can be refinished to look new again.

Furnishings 

Polyurethane, mostly in the form of flexible foam, is one of the most popular materials used in home furnishings such as furniture, bedding and carpet underlay. As a cushioning material for upholstered furniture, flexible polyurethane foam works to make furniture more durable, comfortable and supportive.

Marine 

Millions of Americans enjoy boating each year. Part of boating’s ongoing popularity is thanks to improvements in boating technology, to which polyurethane materials make an important contribution.

Polyurethane epoxy resins seal boat hulls from water, weather, corrosion and elements that increase drag, affect hydrodynamics and reduce durability. Boaters today can have the comforts of home on the water, thanks in part to flexible polyurethane foam. In addition, rigid polyurethane foam insulates boats from noise and temperature extremes, provides abrasion and tear resistance, and increases load-bearing capacity all while adding minimal weight. Thermoplastic polyurethane is also great for use in the maritime industry. It is elastic, durable and an easily processed substance, well suited for wire and cable coatings, engine tubing, drive belts, hydraulic hoses and seals and even ship molding.

Medical 

Polyurethanes are commonly used in a number of medical applications, including catheter and general purpose tubing, hospital bedding, surgical drapes, wound dressings and a variety of injection-molded devices. Their most common use is in short-term implants. Polyurethane use in medical applications can be more cost-effective and provide for more longevity and toughness.

Packaging 

Polyurethane packaging foam (PPF) can provide more cost-effective, form-fitting cushioning that uniquely and securely protecting items that need to stay safely in place during transit. PPF is widely used to safely protect and transport many items, such as electronic and medical diagnostic equipment, delicate glassware and large industrial parts.  A versatile on-site solution for many packaging challenges, PPF can save time and be more cost-effective by providing a custom-fit container with each shipment.

Introduction to Polyurethanes: History

Polyurethanes can be found in liquid coatings and paints, tough elastomers such as roller blade wheels, rigid insulation, soft flexible foam, elastic fiber or as an integral skin. No matter how polyurethane is transformed, the underlying chemistry is the result of one man’s genius, Prof. Dr. Otto Bayer (1902-1982). Prof. Dr. Otto Bayer is recognized as the “father” of the polyurethanes industry for his invention of the basic diisocyanate polyaddition process.

The origin of polyurethane dates back to the beginning of World War II, when it was first developed as a replacement for rubber. The versatility of this new organic polymer and its ability to substitute for scarce materials spurred numerous applications. During World War II, polyurethane coatings were used for the impregnation of paper and the manufacture of mustard gas resistant garments, high-gloss airplane finishes and chemical and corrosion-resistant coatings to protect metal, wood and masonry.

By the end of the war, polyurethane coatings were being manufactured and used on an industrial scale and could be custom formulated for specific applications. By the mid-50’s, polyurethanes could be found in coatings and adhesives, elastomers and rigid foams. It was not until the late-50’s that comfortable cushioning flexible foams were commercially available. With the development of a low-cost polyether polyol, flexible foams opened the door to the upholstery and automotive applications we know today.

Formulations, additives and processing techniques continue to be developed, such as reinforced and structural moldings for exterior automotive parts and one-component systems. Today, polyurethanes can be found in virtually everything we touch—desks, chairs, cars, clothes, footwear, appliances, beds as well as the insulation in our walls and roof and moldings on our homes.
