Sound reduction underlayments

Quiet Please    

Keeping your home quiet can be a challenge.

Sound transfer between rooms, floors and condos can be a problem especially if you have noisy neighbors and if they have hard surface floors. Ceramic tile is probably the worst offender when it comes to transferring sound to neighbors below. Whilst nothing in the floor industry is proof anything, there are several different underlayment’s that can help reduce the transmittal of sound.

The IBC, “International Building Code” has two methods of testing sound. The IIC, “Impact Insulation Class” tests the ability to block impact sounds i.e. footsteps and objects dropped on the floor. The STC, “Sound Transmission Class” tests the ability to reduce airborne sounds such as voices, stereo systems and T.V’s. The results of the test are combined to create a number; the higher the number the better the resistance to sound. Ratings of 50 or above will satisfy the minimum requirements of the International Building code. The test evaluates the sound transfer over various combinations of building materials within the floor/ceiling assemblies and not just testing the flooring or underlayment. By using a good underlayment you are adding to the resistance of sound transmittal. See the following table for a general idea of what the IIC and STC rating numbers mean.

IIC/STC lab	FSTC field
26-30	20-22	Most sentences clearly understood
30-35	25-27	Many phrases and some sentences understood without straining to hear
35-40	30-3	Individual words and occasional phrases clearly heard and understood
42-45	35-37	Medium loud speech clearly audible, occasional words understood
47-50	40-42	Loud speech audible, music clearly heard
52-55	45-47	Loud speech audible by staining to hear, music normally can be head and may be disturbing
57-60	50-52	Loud speech essentially inaudible; music can be heard faintly but bass notes disturbing
62-65	55-60	Music heard faintly, bass notes “thump”; power woodworking equipment clearly audible
70-	60	Music still heard faintly if played very loud
75+	65+	Effectively blocks most airborne noise sources

IIC-STC 50 is the International Building code.

Rubber underlayment

Solid rubber is without a doubt the most resilient underlayment available. In fact, 2mm of rubber underlayment is equal to 6mm of the common underlayment cork. Rubber underlayment can be used with most all wood flooring installations, including glued down, nailed down and stapled down. It is also specified for use beneath ceramic tile, cork floors, carpets and a variety of resilient sheet and tile floors. As is the case with acoustic cork, whenever you are installing flooring by a method other than free-floating, the underlayment must be attached to the sub-floor as opposed to simply laying it down.

Rubber underlayment is specifically designed to increase the IIC rating and STC rating of a floor to meet or exceed building code requirements. The most common rubber underlayment thickness installed is 5 MM (1/4″). Rubber underlayment performs best when installed between two rigid surfaces. The sub-floor will act as one rigid surface and the finish flooring acting as the second rigid surface, whether it is tile, hardwood, laminate, or particle board with vinyl, will create a sandwich of materials with a flexible core. Rubber underlayment will always perform best installed over concrete, but whether the sub-floor is concrete or wood the STC rating will easily reach the high 40’s STC range.

Using Cork Underlayment

Acoustic Cork: Cork materials, unless incredibly thick (1″ +), will not significantly improve the IIC rating of a floor. Cork has been tested to perform only about a third as well as rubber underlayment of the same thickness. It has remained a popular product largely because of the cheap price tag and partly because of the implied environmentally friendly aspect. Saving a couple hundred dollars on a small project does not really add up to true savings if the product purchased does not actually work.

Carpet with Carpet Pad

A carpeted environment is quiet because the pile surface absorbs surface noise at the source. On a concrete floor with no cushion, a carpet registered an impact noise rating of +14. The same carpet with separate cushion had an impact noise rating of +25—again significant improvement. Carpet cushion can reduce the impact exerted on floor covering by one-half.

This amounts to a smiley face.

Sandstone and Quartzite May 15, 2012

Sandstone is a sedimentary rock originating from the weathering and breakdown of other rocks. Sandstone was formed from grains of sand instead of silt or clay, so its final appearance is that of a rock made of compacted sand. Here we see a picture of a Jurassic sandstone from the Utah.

 

Sandstone is a sedimentary rock originating from the weathering and breakdown of other rocks. Sandstone was formed from grains of sand instead of silt or clay, so its final appearance is that of a rock made of compacted sand. You can see these sand grains with a magnifying lens, sometimes without one. Very compact sandstone is sometimes used as a gem rock if it can be made to take a good polish. The banding in sandstone is usually from bedding of different sediments. This kind of sandstone is also called “picture sandstone” if the patterns are reminiscent of sand dunes or other landscape.

The hardness of sandstone may be difficult to test. If the sand grains have not been cemented well or have been cemented by calcite, the sandstone will seem softer. The individual quartz sand grains will still have a hardness of 7, but the rock may crumble or disintegrate in your hand, making it look soft. Testing the hardness of rocks and natural stone is less effective than testing the hardness of minerals. A rock is basically a mixture of various minerals, although it can contain non-mineral materials such as natural glass and fossils.

 If sandstone becomes compacted and heated enough in the depths of the earth, it forms the metamorphic rock known as quartzite. The best way to distinguish between quartzite and hard sandstone is by looking at broken surfaces under magnification: sandstone breaks around the grains of sand, but quartzite is so tough that the fractures go right through the sand grains (if you can even tell them apart).

Pure quartzite is usually white to gray, though quartzite often occur in various shades of pink and red due to varying amounts of iron oxide. Other colors, such as yellow and orange, are due to other mineral impurities.

We would love for you to stop by Carpets Plus store in Steamboat Springs and take a look at all our natural stone samples. They are all beautiful and so interesting even if you are not doing a home improvement project just yet.

Cleaning Natural Stone May 8, 2012

Taking care of your natural stone does not need to be difficult. There are a couple of do’s and don’ts to know but basically you just need to use a cleaner especially designed for natural stone. Natural stone is very porous so the best way to prevent stains is to treat the surface with a protective sealer at the time of installation. The sealer fills in the pores and repels spills on the surface, allowing you time to completely wipe spills away. If your tile has not been sealed you can thoroughly clean your tile and apply a good sealer. Once your stone is sealed you can simply dust mop your floors frequently using a clean non treated dry dust mop. Sand, dirt and grit do the most damage to natural stone surfaces due to their abrasiveness, therefore if you use mats or area rugs inside and outside an entrance you will help to minimize tracking in the sand, dirt and grit. Make sure you use non-slip padding under your mat or area rug.

When using a cleaner on Natural Stone only use a neutral pH cleaner — you never want to use anything acidic on natural stone surfaces as they can ruin the surface of the stone. Never use cleaners containing acids, scouring powder, abrasive bathroom or soft kitchen cleaners, vinegar or lemon juice. So, all you margarita drinkers out there:  no limes on the counter tops!

For your peace of mind Carpets Plus has a variety of worry free cleaning products, sealers and area rug padding that will keep your natural stone looking great. My favorite stone cleaner is Carpets Plus “All in one Cleaner and Polish” for natural stone; we have plenty in stock at our store amongst other specialized cleaners. If your tile is looking a bit tiered we also have restoration products to give your natural stone a little lift in life.

Slate May 2, 2012

This picture is of both slate and quartzite, do you know the difference? It can be quite misleading. The outer two stones are slate and the inner two quartzite.

Slate is often used for flooring, wall tile and deco tiles. It is Mother Nature at its best and is very popular for entryways and public areas. The beauty of slate is its variation of color and the variation of texture of its surface. In Steamboat Springs you will often see slate in entryways as it hides the dirt and its irregular surface is more slip resistant which helps when people are walking around in ski boots!

Slate should be sealed to improve durability and appearance and increase stain resistance. Slate can be bought either gauged, meaning that the back surface is ground for ease of installation, or un-gauged. In either case the surface of the slate retains its natural clef so even if the surface gets chipped by the odd ski boot it will not affect its appearance as the color goes all the way through.

Limestone April 25, 2012

Travertine and limestone are both sedimentary rocks composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral. Travertine is a banded, compact variety of limestone formed along streams, particularly where there are waterfalls, and around hot or cold springs.

There are far more geological similarities than differences between travertine and limestone. Both are formed by the settling of plants, animals, sea shells, sand, and mud on the sea beds. As millions of years pass, this sediment continues to settle and the weight of additional settlement causes the limestone and travertine to compress and harden. This process creates the fossils frequently found in both of these stones. If, at this stage, hot water rich in carbon dioxide from hot springs percolates through the limestone and dissolves some of the stone leaving behind inclusions, holes or voids, travertine is formed. As the water resurfaces, the sudden drop in pressure and change in temperature causes the water to release carbon dioxide gas. The calcium carbonate or limestone then re-crystallizes as travertine.

Limestone is a good building material, especially for cathedrals, since you can carve it easily. It does get eroded by being dissolved slowly by rain, especially acid rain. Limestone, like all natural stone should be sealed and can be maintain by a neutral pH cleaner, you never want to use anything acidic on natural stone surfaces as they can ruin the surface of natural stone.

Stop by Carpets Plus and test your skills at distinguishing these two products, and check out our inexpensive cleaners.

Travertine April 17, 2012

Travertine is a form of limestone deposited by mineral springs, especially hot springs. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the U.S., the most well-known place for travertine formation is Yellowstone National Park, where the geothermal areas are rich in travertine deposits.

Travertine is often used as a building material. The Romans mined deposits of travertine for building temples, aqueducts, monuments, bath complexes, and amphitheaters such as the Coliseum, the largest building in the world constructed mostly of travertine.

Because travertine is such a porous material, it should be sealed before use in construction or renovation projects. It is most commonly used for counter-tops and flooring, but may also be used in showers and tub surrounds as well as in exterior decor.

Travertine is available in different colors and finishes, from natural, neutral colors such as creamy white and beige to tan and reddish brown. The color depends quite a bit on the impurities and iron content of the stone. The different finishes include honed, polished, chiseled and tumbled. Honed travertine is smooth, but unlike polished, it has a matte finish. Polished travertine is smooth, buffed and polished until shiny. Tumbled travertine has a rougher, textured finish and often has rounded corners for an antique look. Remember just because a stone may be shiny it doesn’t mean it is sealed.

Never use cleaners that contain vinegar or citrus oils on travertine. Even water can be harmful to the texture of travertine if it is allowed to sit on the stone for long periods of time.

Travertine is imported mostly from Italy, Iran, Mexico, Turkey, and Peru. A decade ago, Italy had a near-monopoly on the world travertine market.

Granite April 10, 2012

Granite is probably the most known stone used in the home. Granite is very grainy in appearance with the crystals in the granite being clearly visible. Granite was formed from the magma of a volcano; it cooled very slowly creating large crystals in the stone. Granite is a tough, durable rock composed primarily of three different minerals. These minerals are easy to see due to their different colors. The white mineral grains found in granite are feldspar. It is the most abundant mineral found in granite. The light gray, glass-like grains are quartz, and the black, flake-like grains are biotite or black mica.

Granite is often used in the kitchen for both flooring and counter tops. It has a Moh hardness rating of 7 – 8 and is a very dense stone that resists heat and is difficult to scratch. Granite colors run from light colors such as white, sand and gold to dark colors such as black and green. Neutral colors such as beige, brown and grey tend to be very popular in most homes.

Like all natural stones, granite will need to be sealed with a good quality penetrative sealer once installed. To check that your granite has been sealed properly, sprinkle some water on it.  If the water beads up on the surface of the granite, it has a good seal. To maintain your granite, regularly dry dust using a clean cloth and damp wipe as needed. Always use a stone cleaner or a mild, neutral detergent. Never use products that contain acids such as lemon. Quickly wipe up spills to avoid absorption into the stone. If your granite has absorbed oil or impurities from water, use a stone poultice to help restore the stone. Poultices are spread over the stone and covered with a sheet of plastic. The poultice draws the stain from inside the granite to the surface so it can be cleaned.

Marble March 23, 2012

Marble is a stone that started out as a limestone; the limestone over time recrystallized due to heat and pressure under the earth’s crust. Marble comes in a wide range of colors. The color of the marble is determined by what impurities were present in the limestone in its early days of life. Its main characteristics are heavy veining, graininess and beauty of color.

Once installed marble will need to be sealed with a good quality penetrative sealer. This will prevent water and other liquids penetrating the marble. A good sealer will last for approx. 5 years depending on usage. Sealer is a liquid that is easily applied using a sponge and can be done by the homeowner; but remember to clean first, dirt sealed in is dirt for life!

Marble due to its MOH’s hardness rating of 2.5 – 5 is more suitable for master bathroom floors rather than an entry or kitchen floor. Granite has a rating of 7 – 8 and would be better suited to areas with heavier use. To maintain your marble regular dry dust mopping using a clean cloth and damp mopping as needed; and remember Mother Nature has the last say in variation and strength.

This is my master bathroom which we tiled in marble and porcelain tile on the floor with a marble insert and deco to tie it all in. I love it!

The relative hardness of Natural Stone March 8, 2012

Learn the relative hardness of Natural Stone.

One of my favorite flooring materials is natural stone. The most common natural stones are marble, granite, travertine, limestone, slate and quartzite. One of the best qualities of natural stones is that no two stones are alike. Because stone is made in nature, its colors vary, making it more beautiful. When considering using natural stones in your house or in a project, you will want to consider their properties to determine which natural stone is best for the job. One of the most important properties of natural stone to consider is its hardness. The harder the stone the less likely it will scratch. On the “Mohs” hardness scale where 1 is the softest and 10 the hardest the following stones are;

Marble          2.5 – 5

Granite          7 – 8

Travertine     3 – 4

Limestone     3 – 4

Slate              2.5 – 4

Quartzite       7

Based on the above hardness my preferences are to use granite on kitchen counter tops and marbles and travertine in the bathroom.
