Gypsum Dry walls-The Future of Construction

The infrastructure and building sector in India has prospered in the recent years. Therefore it’s no wonder that the industry has seen much progress in technology and new innovations, all of which are targeted at completing construction of buildings and infrastructures at a much faster rate and achieve high performance. In keeping with the demand for faster building construction, one of the practices that has been steadily gaining momentum in popularity in these days is drywall construction which is based on gypsum plasterboard. Drywall panel also known as gypsum board or gypsum panel, plasterboard or wallboard is made of calcium sulfate dihydrate (gypsum) with or without additions and normally compressed between a backer and a facer.
Why Gypsum Products
Gypsum products are extensively used in construction business in foreign countries and the trend is growing fast in India too. The main reasons why this material has become so popular are its properties which are unique. It has better acoustic and thermal insulation properties. It offers excellent passive protection against fire, impact resistance and moisture resistance when it is used together with the correct systems. In the ‘Drywall’ construction, as indicated by the word, water-free construction techniques are used. Therefore, it is a technology that is highly environment-friendly. When combined with steel framing and gypsum plasterboards, drywall systems are a popular standard especially when it is applied to interior wall construction. Gypsum plasterboards are much lighter in weight and can be installed very quickly, thus effecting huge savings in labor and also giving construction flexibility.
The future Scenario
In the future, the buildings are going to be taller and taller. Naturally, safety regulations will be stricter and there will be need for lightweight building materials that have superior strength, thus the traditional construction materials will become obsolete. Gypsum plasterboards appear to offer tailor made solutions for the above conditions. They weigh eight to ten times lesser than traditional masonry systems and can reduce construction speed by three to four times. Gypsum has good moisture and fire resistance properties, and therefore gypsum plasterboards have high safety levels as well. They are totally recyclable, and therefore, are environment friendly solution for construction. It is therefore of little surprise that more than 80% of interior construction in affluent countries use drywall techniques.
Conclusion
In India too drywall products are being accepted more and more over the years. Initially, the trend began with the need for large office spaces for the growing IT sector. But of late, other sectors like hotels, airports and hospitals are leading the demand.

Also, with the frantic urgency for India to control its carbon footprint produced by construction and other activities, energy efficient and clean solutions like drywalls, appear to be the right step forward.

Commercial Roofing: The Benefits of Green Roof Systems

The green movement created a new type of roofing system that combines plants, soil, and other natural elements for forming a rooftop ecosystem. Famous in many areas, green commercial roofing systems (also known as natural systems) are swiftly becoming the favored option to conventional systems that do not weather well, and burden building owners with high repair bills. If you plan to implement a green roof, below are seven reasons for moving ahead with your plans:

Improved Storm Water Management

Green systems make storm water management better by storing water in the substrate, where plants absorb it, and then sent back to the atmosphere by evaporation and transpiration. By preserving storm water, a natural roof can help prolong the lifespan of drainage systems by lessening the volume of water they acquire. Research shows that a natural system can hold up to ninety percent of the rain falling on them.

Reduced Ambient Heat

During summer, a roof can be a main source of undesirable heat; since it absorbs sunlight, it generates heat energy that is transferred inside the building. Natural systems stop this from happening by absorbing sunlight without transferring it inside. It is shown by research that a natural roof can lessen the need for air conditioning by up to seventy-five percent.

Improved Energy Efficiency

The more insulation its roof has, the less heat a building loses in the winter and a natural roof provides an additional layer of insulation. If the annual utility bill of your building is very high, implementation of a green system can help bring it back under control.

Reduced Repairs

Since natural systems are self-sustaining, typically they need lesser repairs than conventional commercial roofing. If you have to save money on roofing repair, implementation of a natural system will help you do it.

Improved Building Value

During a time when eco friendly buildings are favored over buildings using conventional technology, a green roof installation can raise the value of a building to potential buyers. A green roof can also raise the real estate value of a building by making its energy efficiency better.

Attractive to Employees

In urban environments where there is a scarcity of outdoor greenery, buildings having a natural roof can assist companies keep and attract employees. As per research, a green roof can make easier recruitment of employees and lessen employee turnover. If you have to lessen the cost of training or recruiting new employees, a green roof implementation can help.

Noise Reduction

Based on their construction, green roofs can lessen noise outside by up to 50 decibels. The interiors of urban buildings are susceptible to an inflow of low frequency noise caused by automobiles, transport systems, and industrial work. Green systems excel at providing an obstacle to this noise.

Conclusion

If you require a commercial roofing system, a natural system implementation may be the best choice. Besides enhancing the aesthetics of your building, a green roof can lessen ambient heating, better storm water management, lessen the cost of roofing repair, improve energy efficiency, attract employees, improve building value, and reduce noise.

Commercial Carpet Is a Must for Your Commercial Area
Carpets make house or a room look beautiful. Carpets used in business places are called commercial carpets. In today’s hugely competitive world, succeeding in whatever you do is important. There are several things that have roles to play in making any venture like business successful. The interior of a building which include the carpet, the area rugs or tiles are among the items that give a professional look to a space. Your commercial place may be anything from an office to restaurant, to hotel or something else.
Choice of Carpets
There is a range of selection of commercial carpets to be found in the market and it is easy for you to find the type that you like for your office or any other area of commercial activity. Your choice of carpet depends on the kind of space you have. Suppose you want your staff to maintain total silence, then you can opt for commercial carpets. The carpet must be thick and also of good quality. You do not replace your carpet every year. So make an intelligent choice as you are doing this for the prosperity of your business.
Advantages
The best advantage of using commercial carpet in your office or any commercial place is that it can mask sounds like footstep. It can be highly disturbing for a person, who is totally immersed in his/her work if he or she is suddenly disturbed by footstep or other clattering noise. The total concentration of the individual is lost not to mention the work affected by this. The design, make, and color of the commercial carpet are also critical. Try to select a commercial carpet in mild color tones. Of course, you do not want your office to look gaudy with abnormally bright shades of carpets.
How to Select Commercial Carpets
Several stores sell commercial carpets, tiles, and area rugs. Area rugs are not widely used in commercial outlets. However, there are some exceptions like the reception area or some rooms in a restaurant or hotel. Buying commercial carpet, area rugs, and tiles is not a difficult job. Most carpets dealers engage professionals who will help you. They can come to your place and give an exact estimate for the carpet that you will need. He can also tell you how much it will cost.
Conclusion
Maintaining your commercial carpet is important. It should be clean and dust free. So just buying the commercial carpet is not enough, you must know the correct method to keep it clean. Buy commercial carpet that can resist liquid stains. Controlling the stains in a carpet is a difficult job, so remember this while buying commercial carpet so that you can be peaceful.

Choosing a Manual Commercial Door Closer
Door closers play an important role in commercial/office buildings. Manual door closers shut external doors automatically without having to use electricity. They serve two major purposes. First, door closers ensure security because they close whether human force is exerted or not. Second, they help to make sure that fire is not spread from one building to another or from one section of a building to the next during a fire accident. Another reason to fix door closers is to prevent indoor air from leaking out and keep outside weather and air outside.
Door Closers Control Noise
Contractors recommend the installation of door closers on every external door of a building. They are particularly important on doors of fire exit and/or doors that open only from the inside. As a matter of fact, many regions and cities have made it compulsory to install them on commercial doors. They are also fitted to doors as a method of limiting noise from travelling from one part to another part of a building or from one room to the next, in case someone forgets to shut a door behind him.
Types of Manual Door Closers
Manually operated commercial door closers come in two major styles: The first type is overhead mounted. One end of these door closers is fitted to the door frame and the other end to the door. It stores the energy generated by the force of opening of the door briefly and releases it to shut the door. Hydraulic springs or dampers within the mechanism stops the door from slamming shut and regulates the speed of closing of the door. This speed and regulation can be adjusted by screws provided.
Jamb mounted closers are hidden door closers working on the very basic principle as the overhead type. However, as the name suggests, jamb mounted closers are concealed from view. They are installed between the door and the inside part of the door frame. They become invisible as the door closes. Speed and control are adjustable as well.
Conclusion
Since both types of door closers do not differ much, choosing one of them depends on your preference. Concealed closers can cost you more in some cases though it is not necessarily so always. As a thumb rule, if aesthetic appearance won’t matter, overhead commercial closers will suffice, like fire doors. When it comes to commercial buildings where aesthetic appearance is important (i.e. heritage buildings), concealed closers are the choice because it will not affect the look of the facade. Many manufacturers make manual commercial door closers in varied finishes in both styles. Therefore it is easier for you to locate one that fits with the building’s decor.

Batt Insulation, Are They a Sound Investment in Soundproofing?
Remember that any insulation of the batt type, though great as a thermal insulator, is not a very good soundproofing agent. If batt insulation like Icynene or fiberglass insulation were as effective as soundproofing products, the large firms specializing in fiber glass insulation products would have taken over the soundproofing industry by now. The real professionals would have gone out of business. Luckily it is not so, knowledge is still respected and it will take some time before the soundproofing companies lose their business. If you take soundproofing seriously, always think of batt insulation, as an additional benefit only. They simply are not capable of being independent soundproofing agents like lead, mass loaded vinyl and closed cell foam.
Acoustic Fire Batt
You will find good batt sound insulation on the market. One type is acoustic fire batt which is a rock wool made from mining slag. When treated with air at high pressure this material derives the properties of a very solid fiberglass insulation. It will provide you with an insulation value of R-13 for the 3 1/2″ batt and an R-19 for the 5 1/2″ variety. Its main function as far as acoustics is concerned is that it provides excellent sound absorption as well as structural dampening of joist and wall cavities. It is a well-known fact that damping a structure, particularly a wooden structure controls the vibration and transmission of sound through the structure.
Cotton Batt
You can find other sound insulators from cotton batt that is good for filling cavities and voids where sound control is important. Cotton being an inert material absorbs sound but sound cannot pass through it like in fiberglass.
Fiberglass Insulators
Fiberglass insulation is rated as being one among the worst soundproofing agents. Sound passes through its fibers causing the irritating noise to appear to be amplified. If you are compelled to use fiberglass insulation ensure that it is isolated from either the ceiling below or the sub floor. Never pack fiberglass inside voids or cavities. By isolating the fiberglass insulation from the ceiling below or the sub floor above you are actually breaking the circuit of sound transmission from the ceiling below to the floor above. It is the same with the walls. If the fiberglass is in contact with one side of the drywall, make sure that it does not touch the other side. This is understandable if you are familiar with the properties of fiberglass insulation.
Conclusion
To conclude, never depend on any batt insulation to be your only soundproofing agent. You will always need the power of lead, closed cell foam, mass loaded vinyl, or Green Glue. You can get further information about great soundproofing agents in the Internet.

Finding a Vibration Isolation Solution

Undesirable noise and vibration can be an issue in many varied areas. One among the most common illustrations is the vibration in suspension parts of an automobile. But, there are many other examples that can be found. Plasma cutters, CNC machines, and many other machines make vibrations that can cause problems. In all of these applications, vibration dampening and isolation is extremely important. What can happen if you cannot adequately dampen and isolate vibrations?

Issues of Excessive Vibration

While the real results of excessive vibration will definitely vary by application, you will find many common issues that can appear. For instance, using as an example the case of automotive suspension components such as tie rods, the most immediate outcome is that your ride will be uncomfortable, lots of noise, and poor handling. But, over time, the absence of proper vibration dampening and isolation will really cause early failure of the suspension components via wear and fatigue. This calls for the question, what must you look for in vibration dampening and isolation equipment?

Finding a Company

The initial thing that you need to find is a company specializing in rubber molding, and also rubber-to-metal bonding. Why is bonding an important consideration? Usually, you will require to bond rubber to metal when creating a combined vibration isolation solution. Finding a company with a lot of expertise and experience in bonding rubber to metal is very important. This demands that the company have a working knowledge of bonding agents, substrate materials, meeting product specifications, dilution procedures, creating custom molding and quite a little more.

How to Select a Company

Besides, while looking for a vibration isolation solution provider, it’s recommended to look at the history of the company. It’s advisable to select a company that has been doing business for many decades and has really played a vital role in the development of the rubber industry. Whether you need noise reduction and vibration isolation for an engineering application or an automotive application, it’s vital that you select the right company with which to work.

One way of finding out whether company is worth your time or not is to take a look at their catalog of existing products. An experienced manufacturer might well have a present solution that can suit your application. Otherwise, you may find that the company has a product that can be altered easily for meeting your specific requirements. This would save money and time over custom vibration isolation solution created for your application. But, if the company does not have a present product that will work or that can be altered to work, then you have to ensure that they do have much experience in creating custom solutions for reducing noise and vibration via the use of rubber.

Conclusion

These are just some of the considerations that you have to make when considering a vibration isolation solution. The right company will offer compression mounts, plate mounts, conical isolators, torsional mounts, bumpers, square mounts, flange mounts, center bonded solutions, and insulator pads besides custom solutions.

Are Loud Commercials Bugging You Four Solutions to Give You Peace and Quiet
TV watchers face a problem. Networks deliberately make their commercials much louder than their main programs. This irritates some viewers. Many viewers have complained to the authorities concerned. Not surprisingly, the problem is not attended to in spite of the complaints.
One Possible High-tech Solution
Interestingly, one solution is put forward, that is, a new electronic device, named Dolby Volume, which is supposed to modulate the TV volume and at the same time not affecting the quality of the original soundtrack. This is a rather excessively, complicated solution. However, you may wonder why somebody does not think of simpler, more open solutions instead of waiting for the technology to solve the problem, or expecting the government to set the networks in order.
Three Low-tech Solutions
One of them is the familiar “fast-forward” button. Record all your favorite shows with your DVR while fast forwarding through all the unwanted commercials. You may be able to save precious time, say, about 16 minutes per hour. Your TV watching time is reduced by 25%.
You can use the “mute” button. But for this you must have your remote control within reach. But that is not feasible if you fall asleep in front of the TV. You can mute the TV when the commercials are on and use the time to talk with your family or read books. You can un-mute the volume once your program comes back on.
The other obvious way is the “OFF” button. Switch off your TV and then you do not have to bother about the TV’s volume. You would get all your friends to do the same and all of you would stop dealing with the TV Company and soon such company would be out of business. Is it a practical solution?
No a la carte Programs
Many of you may be annoyed that cable companies try to force you to pay for bundled packages of their programs which include adult programs so that you can get to watch family-oriented programs. You can’t choose programs only of your choice. Here again appealing to the government against the offending company is not the solution. You can cancel your contract with the cable company.
Conclusion
TV is so addictive that most people cannot do without it. If you want certain specific programs you can rent some of them or indulge in real family-oriented activities instead of watching TV. To many TV is a bedtime relaxation formula to go to sleep. That too may not work always. Try to stop watching TV before sleep and develop the habit of reading good books. Learn to fix the many problems with TV yourself instead of waiting for the government or some unknown inventor to solve matters and suffer unnecessarily in the meantime.

Anti Vibration Mounts

In the engineering industry, mechanical devices produce and transmit vibrations when they are operating. Reducing this vibration in such a way that it does not affect the desired mechanical functions is big issue. That’s where you need an anti-vibration mount (sometimes called as a vibro-isolator). Both noise and vibration can be annoying outcomes of equipment operation, but that’s not the worst part. They can also cause destruction to costly equipment in the process. Anti-vibration mounts are meant to isolate harmful vibration in a whole range of industrial, scientific, and consumer equipment. The installing of these mounts reduces the impact of vibration on the people engaged in engineering, the equipment used, and the structure that is engineered.
How it works
The way the anti-vibration mount realizes these objectives is by balancing out frequency of the system with the disturbing frequency (also called the excitation frequency). While these two are usually synchronized, a vibration isolator forces the two out of sync, reducing the problems they would otherwise cause. Actually, a good anti vibration mount is capable of absorbing more than half of the energy generated by the vibration.
How does all of this affect the industrial applications where vibration is an issue? Costly machinery and equipment have longer life because the sensitive parts are protected from impacting and damaging one another. Whether it is the largest jet airplane or the smallest electronic smart phone, the anti-vibration mount is able to almost prevent damage due to shock, noise, and vibration. Fans, motors ventilation units, pumps, distribution panels, machinery, manufacturing equipment, compressors, transformers, and air handling equipment are just few of the classic applications that get benefited from anti vibration mounts.
News Headlines on Anti Vibration Mounts
The universal demand for vibration-isolation is clear from a quick scan of the recent news headlines. A newly released report says that chassis of computing and storage server is fitted with an “anti-vibration mechanism for the fans for a minimum of undesirable noise.”
CBC News from Canada reports that a nuclear generating station “had to be shut down for two weeks in late summer for repairs” as a consequence of operational problems it was going through. Those problems were related to vibration.
It appears that the station had developed a vibration problem in a non-nuclear pipe that carried steam, probably to the plant’s turbines, and was unable to realize full power due to the problem. An anti-vibration mount installed at the right time might have prevented the costly downtime.

Conclusion
All of the above news stories and other facts illustrated show how waste of time and avoidable expenses that can result if vibration issues are neglected. The installation of a simple and inexpensive anti vibration mount is the solution for saving equipment users from the headaches that would otherwise result.

Aluminum Foil’s Role in Sound Insulation

When selecting insulations, one thing that many buyers do not think about is the amount of sound protection this is going to provide. However, this is what every insulation buyer must ask him or herself, particularly if noise is a problem in the structure being insulated. This is because some kinds of insulators provide improved acoustical insulation than the remaining.

Sound Insulation of Aluminum Foil

One among the best materials when considering sound insulation is aluminum foil. Easy to install and lightweight, it is environmentally friendly as an insulation material. It can not only be recycled, but is also free of toxins and odors. Besides heat isolation and reflection, it also provides vibration shielding and superior acoustical.

Reflective aluminum foil is the most commonly used material when considering radiant barriers. A radiant barrier is a method of lessening the heat radiation falling on or coming from the surface of a material. These barriers reflect radiant energy. This reflective capability secures against heat through the hot summer months and accumulates heat through the colder winter months.

Few of the qualities making aluminum foil receptive to this process are: 1) It has no considerable mass for absorbing and retaining heat; 2) Its emittance values are very low. Also known as E-values, this tendency considerably lessens transfer of heat by radiation.

The above explains why it is a good kind of insulation, but how does it specifically relate to sound insulation?

The explanation is that similar to the way aluminum foil retains and absorbs heat, it also retains and absorbs noise, corralling and protecting it so that it becomes almost unnoticeable. Actually, as an isolate it offers noise cancellation of up to 85%.

In what particular situations is aluminum foil a better option to steel?

If the noise is usually at high frequencies (a hissing noise) then a material that is lighter like aluminum lagging could be used. Actually, only in low frequency noise cases steel is used since steel has a surface mass that is much heavier.

Besides its lighter weight, also aluminum foil is a more inexpensive noise insulation material. Sold typically in rolls, such insulation has lamination with aluminum foil. The benefits of using aluminum foil insulation don’t stop with acoustical isolation in industrial and commercial applications, although. They also extend to temperature control, fireproofing, the prevention of condensation, and the conservation of energy.

Conclusion

When lightweight and compact insulation against noise is required, aluminum foil provides business owners and other individuals all of the safety they are looking for without a huge expenditure in cost. At the same time, it also offers additional levels of protection against moisture, heat, and vapors.
