Soundproofing your basement

In today's world, basements are no longer simply places to store things like a glorified garage. With the price of housing ever on the rise, many people are converting their basements into rental spaces where they can make a little extra income each month. There are also a lot of folks who want to create a refuge space for reading or meditation or even a home theater in their basements. In this article I am going to talk about soundproofing your basement from the tenants below or from the noise transmitted by a home theater. The first order of business is to talk about the ceiling. Many times pipes and conduits as well as electrical and cable lines run between the joist cavities in a basement ceiling. A lot of people feel that need to have access to these components, but in order to achieve great soundproofing, there devices need to be sealed up by constructing a sealed drywall ceiling below. If you are concerned about the plumbing and wiring, have a professional come in before your drywall in your new ceiling. Remember that 90% of your plumbing and wiring is behind drywall and if there are problems with them then naturally the drywall will need to be removed. My point here is that if the plumbing and wiring has been inspected and given a clean bill of health, then go ahead and seal up the ceiling below. Generally most basement areas have low ceilings which prevents us from installing a fully floated ceiling, however there is always room for materials like mass loaded vinyl that can be stapled or nailed directly to the bottom of the joists like a membrane. You will caulk all of the seams as well as around the entire perimeter of the MLV using a good quality acoustical caulk, stay away from cheap silicone caulks, they do not work as well. Once the MLV membrane is caulked and sealed properly, it is advised that you also tape the seams with a lead tape or a mass loaded vinyl sealer tape. You will tape directly over the dried caulk. Now it is time for a layer of drywall. I would recommend a layer of 5/8" fire code drywall. This application will stop most of the airborne sound transmission and some of the impact noise from above, but the best way to alleviate the majority of the footfall or impact noise is to float your ceiling using sound clips and metal furring channels. I will talk more bout them in subsequent articles. There is one other method for soundproofing a basement ceiling that I will briefly discuss. Instead of using the mass loaded vinyl, consider installing 2 layers of sheetrock with a layer of Green Glue applied between the 2 layers. Here's how it works. First you make sure you have your batt insulation in place between the joist cavities, this is only necessary if your need the thermal protection of the insulation. Next you would screw in a layer of 5/8" drywall. Always screw in your drywall; never nail it in especially in a ceiling application. Then you will lay out your second layer of 5/8" drywall on saw horses, but on this layer you will apply 3 tubes of a product called Green Glue top the backside of the drywall. Green Glue is a visco elastic damping compound that is used to deaden or dampen the existing drywall and the newer layer that is being installed. You could apply only 2 tubes of Green Glue per 4' X 8' sheet of drywall, however using 3 tubes per sheet of drywall is much better for soundproofing. Once you have applied the Green Glue to the backside of the second layer of drywall, you will simply screw in the second layer directly over top of the first layer. A little hint here is to screw the second layer of drywall down as tightly as possible without pulling the screw through the drywall, this will insure the best dampening possible of both pieces of drywall. After that second layer of drywall and Green Glue are installed, you will simply tape mud and texture the ceiling as you would a normal ceiling. Well, that's all there is to soundproofing a basement ceiling.

Soundproofing a wood or tile floor

I have been getting a lot of requests lately to write an article on soundproofing a wood or tile floor in an upper apartment or condo unit. The solutions are pretty simple if you're installing wall-to-wall carpeting, but things get a little more complicated when you're dealing with hardwoods, ceramic or vinyl flooring. To begin with, when a manufacturers STC (Sound Transmission Class) claims appear to be too high always read the fine print. Generally they mean that you can only reach this high STC value in conjunction with a myriad of other products that must to be added to your floor or ceiling assembly. For example, if you're looking at ?"cork as a floor underlayment and the manufacturer claims that it will give you 55-57 STC, keep in mind that this value will only be attained with at least 3 inches of gypcrete (light weight concrete) poured overtop of the existing sub-floor and most likely the addition of a couple of layers of cement board (Hardy or Wonder board) will be needed as well. All of the STC values of these products are additive and so the manufacturer makes his claim hoping you won't read the fine print.

Even though these values are additive, there is always the law of diminishing returns to contend with, so you still may not reach your STC goal even though it says you do on paper. Many times the call out for a floor or ceiling assembly is such that ceiling below must be floated on sound clips and furring channels or resilient channels in order to obtain the 55-57 STC values that some manufacturers claim to get from their product. Basically, no soundproofing product on it's own will give you a 55-57 STC value. If you find one that does, please let me know and I'll get it on the website immediately. There are no magic formulas. What it boils down to is simply this, very few products on the market today can give you an STC value greater than 32 to 35 STC on their own, and thus these high STC claims are very misleading to say the least.

I had a customer who told me that a 1/8" cork mat would give him an STC rating of 55- 57 when laid beneath carpet and pad. I smiled and had him show me the cut sheet (spec. sheet) for the cork. The sheet called for the addition of a poured gypcrete sub floor and numerous other items that I can't recall off hand, that were needed in order to meet the 55-57 STC. Needless to say, he was shocked. Its back to that old adage, if it sounds too good to be true, it is! That being said, the absolute best way to soundproof an upstairs unit from a lower one is by floating the ceiling in the lower unit using sound clips and furring channel (hat channel).

This is the most common method used by contractors who have done any type soundproofing in their careers. This method, though more economical than the sound clips system is only about ? as effective and is generally installed improperly even by the most competent of contractors. The difference in cost for the sound clips and furring channels is well worth it to effectively soundproof a ceiling from impact or airborne noise from above. Now there are other materials that can be placed over the sub floor above that will help stop impact noise as well as block most airborne noise from below or above. One is called American Impact Pro and the other is American Impact Standard. These recycled rubber products that are specifically designed to be installed underneath hardwood and tile floors. They will also work well under carpet and padded floors.

When dealing with a hardwood floor, you can also use a product called America's Best, which is a mass loaded vinyl that is bonded to a layer of ?" closed cell foam mat. This material will provide a certain amount of floor resilience that's prevents much of the impact noise from traveling downward, however the only way this system will work properly is if the wood planks are at least 6' in length, it is also preferred that planks be interlocking on the sides. Mass loaded vinyl with foam backing is a resilient product and will allow the new hardwood floor to actually flex when walked on. This resilience adds to the footfall protection to the ceiling below. Long planked wood floors are the only hard surfaced floors that will work with America's Best vinyl. Other floors such as vinyl or ceramic tile or Pergo floor systems will not work with this product as these surfaces will have a tendency to separate or crack.

Finally, if your condo or co-op association board has a call out for IIC (impact isolation coefficient) then you will need to call a professional to discuss the procedures you'll need to follow in order to meet that particular IIC call out. Impact isolation is a whole other chapter in the Soundproofing Bible and will have to wait until next time! Thanks for reading and learning about soundproofing a wood or tile floor.

Proofing Employee Motivation

 by: Dr. Douglas Waldo c/o ARA Content

(ARA) - As we hear more predictions of an economy showing signs of weakening, managers around the country are asking a couple of key questions: Are we prepared for a recession reminiscent of the early 1990s? Did we learn enough from experiences nearly a decade ago to improve how we perform in 2001? The answer: probably.

While the financial experts monitor and project the extent of an economic slowdown, little doubt remains that the early years of this decade will likely feature layoffs and restructuring across every industry. These staff reductions, or even the anticipation of them, can have a dramatic influence on employee motivation and productivity. Recognizing the warning signs of declining motivation and overall morale can allow managers to respond quickly with intervention strategies aimed at propping up declining productivity.

According to Brian Dailey, a business consultant to the staffing industry in Oklahoma City, there are many warning signs of declining employee motivation that can be expected during recessionary economic times. Some of these include: increased sick days as employees interview for other jobs, increased employee use of Internet time to surf job boards and send out resumes, fewer requests for long vacations, and greater interest among employees regarding company sales or financial strength.

Dailey suggests that while employee motivation may lag for a time, some incidental benefits to employers may include less tardiness and improved work habits as employees position themselves to survive potential staff reductions. Few employees will want to be perceived as marginal performers if the possibility of recession and restructuring looms in the near future.

The real challenge for managers is to develop strategies aimed at protecting employee motivation, despite the fear and concern normally attributed to tough economic times. Dr. Larry Craft, developer of the Craft Personality Questionnaire -- a tool that measures personality and motivation for pre-employment selection systems, understands the impact of uncertainty on employee productivity. According to Dr. Craft, companies looking to reduce expenses by slashing personnel need to take a hard look at the impact on current and future employees before choosing a course of action. "Future employees will tend to look for companies that offer consistency and will likely shy away from jobs in the long run where the potential for turnover is the highest." A company that receives media attention for staff reductions may find that candidates are few and far between when economic times allow for hiring increases.

Dr. Craft agrees however that most companies find it difficult to consider the impact on hiring it will undertake after a recession when the numbers suggest the need for staff reduction in the near term. His best advice is to understand the unique personalities of current employees and open the lines of communication early to avoid many of the problems associated with rumors and false claims.

Thousands of companies have used Dr. Craft's various testing services to do just that in the last two decades, and many find that the resulting productivity requires fewer staff reductions during tougher economic times. Rick Daughtrey, a consultant with CraftSystems(800.228.5866) of Bradenton, Florida, suggests that "it's really a matter of investing the time and resources on the right people and then cultivating them along the way, therefore reducing the need for cutbacks because the right people can typically pay for themselves over the long run."

Managers must learn to assess how they respond to good and bad economic times. Too many companies over-hire in good times and quickly look to downsizing as a temporary fix to slowing demand for their services. It has long been acknowledged that employees are a company's most valuable assets, but many are slow to recognize the full impact of these tough decisions on the motivation of surviving employees. A carefully thought out plan can go a long way in preventing the potential nightmare associated with cutting expenses while attempting to maintain productivity.

Finally, the biggest threat to employee motivation may be a shift in focus to self- preservation rather than team performance. What once was a finely tuned machine may break down as the individual parts become more concerned with whether they can meet their own goals, while failing to recognize that the team's performance may be their greatest hope for individual survival. The lessons learned from the early 1990s are simple: seek expert advice in selecting the right employees for jobs, teach managers to incorporate an understanding of personality and motivation into their communication, develop a game plan that utilizes cross-training to add flexibility to existing staff, and if you must downsize, do it wisely and do it rarely.

Roofing Contractor

 

A contractor is essentially someone who consents to complete a task for a charge or a specialist in the building business, whose job requires hiring workers to construct a ‘paid for’ assignment. Even though a contractor's foremost concern is hiring capable subcontractors, at times he may also carry out some of the construction work by himself. These principles remain the same in reference to a roofing contractor.

Most roofing contractors are highly experienced personnel. Working in such a specific industry over time enables them to learn nuances of the trade and carve a niche for themselves. Most roofing contractors have knowledge and experience of varied roofing materials. This enables them to undertake varied roofing projects over vast terrains.

Roofing is a very important aspect of ones home, which makes it all the more essential for a homeowner to find the right contractor. Roofs are exposed to the elements at all times, which makes regular maintenance a compulsion. Roofing contractors may be called upon to do minor repair work or re-roofing. Clients must always remember that re-roofing is a very profitable venture for contractors, since it involves replacing an entire roof. In order to avoid this, a contractor should be called upon as soon as a minor flaw or condition is detected.

In most cases houses change many hands, making it difficult to locate the original roofing contractor. In such situations a new contractor who is hired should be allowed to study the project and make decisions.

While selecting a roofing contractor, one should select a specialist in order to be certain of quality work. Another effective practice is to work with recommendations from friends and family. Homeowners need to realize the importance of maintaining a roof since even the smallest leak can cause significant damage. Hiring the right roofing contractor at the appropriate time goes a long way in preserving ones home for years to come.
