Also known as drywall, gypsum panels are often used by builders and architects for both residential and commercial construction because of its many advantages. Gypsum board systems meet building code requirements, provide economical fire protection, attenuate sound, are easy to erect, are eco-friendly and have breath function.

Fire Protection

Although gypsum panels have a non-combustible core, building codes mandate that these systems must be fire tested based on a set standard like the Standard Test Method for Fire Tests of Building Construction and Materials.Once tested, numerical ratings are given for fire-resistance classifications. This set standard entails two tests: a Fire Endurance Test and the Hose Stream Test. During the Fire Endurance Test, the material specimen is exposed to fire and tested for a resistance period. The Hose Stream Test subjects the specimen to fire for a period of one half the resistance period. It is then subjected to the impact and cooling from a fire hose. Duration of exposure and water pressure are noted during this test method. If no large amount of water passes through the gypsum panel, the resistance period is then the fire rating for the system.

Sound Control

Apartment complexes, condos and business establishments rely heavily on gypsum walls to limit the transmission of sound between individual units and rooms. Solid area gypsum wall systems have a Sound Transmission Class (STC) rating that can provide more than 60 rating. As long as the wall areas are free of gaps, fully caulked, sealed and have no flanking paths, gypsum panels greatly reduce sound transmission.

Easy to Erect and Secure

Gypsum panel systems are convenient and easy to install and secure during the framing process of construction. Metal components and liner panels are easily stacked and allow for the separation wall to be smoothly inserted. Gypsum board separation walls come in either a solid or cavity design. Solid system designs are erected vertically one floor at a time and inserted into wide tracks. The individual panels are secured by H-studs and set up one after the other along the track. It?s a stacking process that is easily repeated from floor to floor.

Cavity-style systems are generally used in steel stud partitions or gypsum board shaft wall enclosures like those used to enclose a duct shaft or elevator shaft. Like solid systems, cavity-style systems begin with the installation of track at the foundation and are erected vertically. The clips used must be the proper thickness and shape to meet fire-resistant codes. Both solid systems and cavity-type systems weight no more than 10 pounds per square foot. Its lightweight features make it easy to work with while eliminating the need for foundation modifications. Lastly, these systems can be quickly installed leaving no dust in the air.

Eco-Friendly

The gypsum board industry makes good use of recycled materials. Nearly 100 percent of the material used to manufacture gypsum board comes from consumer waste materials and newsprint. The industry also manufactures synthetic gypsum using waste materials from manufacturing plants, such as fossil-fueled power plants. Another green source of gypsum production is the use of production waste from the gypsum board manufacturing plants itself. Waste is reclaimed and entered back into the gypsum board production cycle. When it comes to eco-friendly, the gypsum board industry is hard to top.

Breath Function

Gypsum board panels have a natural breathing component. Its porous body can both absorb and release moisture. With indoor humidity levels high and warm air, it naturally has capitulary ability known as its breathing function. Gypsum board panels help regulate indoor conditions for a better working and living environment.

All around, the benefits of gypsum board make it the go-to product for contractors who do construction or renovation. Not only is gypsum board an advanced technology product, it has a beautiful and smooth appearance that is aesthetically pleasing.

When you're busy hanging drywall and winning jobs, dealing with issues with your drywall supplier can really cut into the time you need to get the job done. How do you find the right drywall supplier for your business? There are a number of aspects you can look at with a drywall supplier that can help you make sure they can take care of your business. Here are a few of the major ones you'll want to look at when investigating a drywall supplier to ensure they're a good fit for you.

A large, diverse inventory ?

When you've got a large job or a number of jobs going at the same time, you need the exact materials when you need them in the quantity required. You don't have time to wait on shipments because a smaller supplier can't keep up with your demand. It's often helpful to partner with an established supplier who understands the flow of supplies required for your projects.

High quality standards ?

When a job is underway, you need to know you're getting the best quality material available. You don't need to waste time turning back orders because a careless loader damaged the corners of an entire pallet of drywall. You don't need to discover after you've installed and finished out drywall that there were quality issues with the wallboard, the joint compound or the screws holding the material in place. A drywall supplier that keeps their inventory protected, in good condition and transported carefully can mean the difference between a successful job and one that leaves you losing business.

Fast, efficient delivery -

You can waste a lot of time getting the trucks and trailers together to haul material for a large job because a supplier doesn't offer delivery. It can even more frustrating when you need to wait for ages for your material to be delivered. We've all had projects when you've called the supplier half a dozen times over the course of a morning just to hear, "Yeah, it's on its way," just to have it finally show up late in the afternoon, after you've sent your crew home for the day with nothing to do. Suppliers that can deliver to your job site quickly and on time are a great advantage when the clock is ticking and you need to get the job done.

Different services offered ?

Can your supplier order in specialty products when you need them without a lot of extra work on your part? Do they have people who have experience in the drywall industry and understand your needs? Are they willing to offer education to help keep your crew moving with the latest trends? These extras can make all the difference between a good supplier and an exceptional one.

Now more than ever people are concerned about mold and the effects it can have on not only personal health but the damage it can cause in your house. Mold is everywhere and has an important job to do outside your house like helping to break down fallen leaves and other organic material. Inside your house mold can affect your health with symptoms as serious as shortness of breath.

Everyday you breathe in mold as you go about your duties. In your house it can be seen as black spots on the shower curtain, little patches of white furry looking stuff on the basement floor, or that unsightly rust color that forms around your sink drains. These are some of the visible places where mold occurs but you may not be aware that mold can grow inside your walls.

Finding Hidden Mold In Your House

The drywall and glues and caulks used while putting up as well as other wall boards can be a prime breeding ground for mold in your home. Since this mold is basically invisible you need to know what to look for to find these hidden health threats.

• Check areas you know have been exposed to water from floods or backups.
• Discoloration or stains on the wall
• Warping, crackling, or buckling of the wall.

**Should you discover a large mold colony please contact a professional to handle the removal process to avoid the health risks and to make sure all the mold is removed.**

Mold hidden in the walls will most likely require the drywall to be removed and replaced. Use the following guidelines when choosing a contractor or doing it yourself.

• The drywall should not be made from cellulose or paper
• Joint compounds need to measure a 10 on the ASTM D 3273 test for mold resistance
• Use mold resistant drywall tape

Joint Compounds

There are two types of joint compounds and choosing the right one is important since about 40% of the wallboard surface is covered by the compound. The first is drying compound that dries when the moisture evaporates. This type is not moisture resistant. The second is setting type which hardens through a chemical process. This type may or may not be right for the job so you need to make sure it has been tested and scored a 10 on the ASTM test.

It's 2017 - do you know how your safety regulations are changing? There are a few changes to the overall OSHA safety regulations that need to be addressed both in terms of crew safety training and the tools used to keep your crew safe. We've summarized these changes below to give you a general overview of those changes, but you'll still want to make sure you clearly understand what the new regulations are and what they mean to how your crew works. Here's the basics of what you need to know.

The two major changes have to do with fall protection. Part of the reason for these changes is the position that falls hold in deadly construction accidents and accounting for nearly 40% of all on-the-job deaths, over four times as high as the next highest job site fatality cause of being struck by an object on the job site. For this reason, OSHA has decided to crank down on job site safety for fall protection to try to reduce this number significantly over the next few years.

As of January 1, the height where fall protection is required will be reduced to six feet from the ground or floor level. Previously limited to working at areas ten feet or higher, this change will strongly impact workers who had previously worked in the area under a home's eaves or ceiling between six and ten feet high. It will add some amount of time to each job, so make sure you include the extra time in your estimate to ensure that your costs will be covered and you can maintain profitability. This rule also applies to open excavations,openings in walls that are less than 39" in height or walkways over excavations.

The change does not impact areas where protection is required at any height, such as openings in a roof such as a skylight or vent, working next to or above dangerous equipment or using boom-supported work platforms.

On October 1, slide guards will no longer be considered an acceptable method to protect workers from falling off a pitched roof. Though slide guards provide some small protection, the old standard required a height of four inches that can withstand 50# of force in the middle of the run. It does not provide adequate protection against falls by, say, a 185# roofer who is sliding rapidly down a high-pitch roof. What's more, when used exclusively to provide fall protection, it can actually increase the risk of Achilles' tendon injury and damage, hence the job site moniker of "cripples".

Both of these changes will require that additional fall prevention and different methods or tools will be required to meet the new requirements. One approach to this is through the use of personal fall arrest and fall restraint systems.

It doesn't matter whether it's the dripping faucet, the creaking framing or the sound of the ice maker dropping ice at 3:00 A.M., what matters is that you can't sleep. You're not alone - an estimated 50-70 million Americans are right there with you in the wee hours of the morning, according to a Centers for Disease Control report issued recently, with nearly 1/3 of adults not getting sufficient sleep every night. But what can you do about it?

In addition to setting aside enough time to get enough sleep, sleep hygiene, or the quality of your sleep practices and environment, plays a vital role in avoiding insomnia-related health problems such as higher blood pressure, depression, memory problems, low energy and inability to focus. In addition to avoiding caffeine, alcohol and large meals close to bedtime, refraining from tobacco use and keeping a regular sleep schedule, you can also take measures to make your home quieter using soundproofing and acoustical products. Here are some common problems and possible solutions to your sleep issues.

Wall Options

If you're willing to undertake a little work, you have several options available to help deaden sound in áyour walls. Insulating using cellulose or fiberglass batting is a great way to capture sound before it keeps you up all night. Soundproof drywall takes the noise reduction a step further, as it's designed to capture and reduce noise transmission through the wall. If you have a particularly problematic area, consider rebuilding the wall with an offset to help prevent the sound from transferring through on the studs, but remember to insulate the air space behind or in front of the stud to get the best noise reduction.

Low Noise Ceiling

Acoustical ceiling tiles aren't just for offices anymore, and they're not the plain squares of past acoustical tile ceilings. From designs that mimic old tin ceiling tiles without all the extra noise to suspended panel options that helps maintain that modern vibe you've built in your home, using acoustical products in your ceilings help absorb noise. If you're dealing with a serious problem, consider installing a suspended ceiling if there's enough room available, because it will create another area for the sound to fade, especially if you apply insulation or additional acousticalámaterials to the void between the floor above and the ceiling below.áThey even help capture noise from the other side of the ceiling, which is handy when your teenage daughter's slumber party is practicing dance moves way too late into the night.

Quiet Views

Get a double benefit from your windows, because energy efficientáwindows that are well insulated tend to also be much quieter. Because of the gas-filled space between the panes, noise transference is also reduced to a minimum, allowing you to ignore the noise the neighbor's cat is making - again. To get the most out of your energy-efficient windows' noise dampening effects, pair them with thermal curtains and sheers to reduce outside noise as much as possible.

Other Products to Consider

If you're serious about getting a great night's sleep, there are a variety of additional acoustical products that can help you achieve that goal. From sound boards and barriers from the best in the business to sound clips that help isolate your room, these products do their part to go the extra mile,áturning your bedroom into a tranquil retreat from everyday life.á
