Vermiculite Insulation - What Is It?

If you have never seen vermiculite insulating an attic, it looks similar to little squares of coloured glass or little grey beads. Vermiculite is a naturally occurring mineral worldwide. When heated rapidly to high temperatures, this crystalline mineral expands into low density, accordion-like, golden brown strands. In fact, its worm-like shape is what gives vermiculite its name. The worms are broken into rectangular chunks about the size of the eraser on the end of a pencil. In addition to being light, vermiculite chunks are also absorbent and fire retardant. It also makes a good insulating material. 

Where Was It Used? 


Sold under various brand names, such as Zonolite Attic Insulation, the insulation came in big bags. Thousands of homeowners simply opened the bags and poured the vermiculite onto their attic floor and sometimes down exterior walls. It was generally not used in new construction.


When Was It Used?


Worldwide, vermiculite has been used in various industries as long ago as 1920. With the upsurge in homeownership during the baby boom, vermiculite insulation was a popular material in the 1950s and continued with the energy crisis into the late 1970s. In Canada, it was one of the insulating materials allowed under the Canadian Home Insulation Program from about 1976 to the mid-1980s. There have been some government-provided grants offered to homeowners to increase insulation levels, reducing energy consumption. Worthwhile checking in to see what may be available. 


What Is The Problem?


The majority of the vermiculite used worldwide was from a mine in Libby, Montana, owned and operated since 1963 by W.R. Grace. The mine was closed in 1990. As well as being rich in vermiculite, this mine had the misfortune of having a deposit of tremolite, a type of asbestos. When the vermiculite was extracted, some tremolite came in with the mix. For Canadian use, the raw product from the Libby mine was shipped to Grace subsidiary F. Hyde processing plants in Montreal, St. Thomas, Ajax and Toronto, and Grant Industries in western Canada. At these plants, it was processed and sold as Zonolite.



What Is The Risk?

 

Asbestos minerals tend to separate into microscopic particles that become airborne and are easily inhaled. People exposed to asbestos in the workplace have developed several types of life-threatening diseases, including lung cancer. Workers in and around the Libby mine developed serious health problems. 

 

Like any hazards, length and intensity of exposure are major factors in the risk of asbestos-related respiratory illness. To assess the risk of asbestos exposure at a house, a sample of the vermiculite would need to be analyzed by a lab. Since most of the vermiculite used in Canada was taken from the Libby mine, the odds are quite good that there is asbestos in the vermiculite in Canadian attics.

 

The good news is that we don’t live in our attics. In addition, as long as it is undisturbed, neither the asbestos fibres bound up in the vermiculite chunks nor the dust will be released into the air. According to the National Institute for Occupational Safety and Health in the U.S., “Most people who get asbestos-related diseases have been exposed to high levels of asbestos for a long time.” Lastly, most of the time the air in your house flows from the house into the attic, rather than into the house from the attic.

 

The bottom line is, like most household products that may contain asbestos, and there are many, doing nothing is often the best approach. Naturally, the risk of exposure increases with the amount of time spent in the attic.


Our Recommendations


If the attic or walls of a house contain vermiculite insulation, leave it alone. Avoid disturbing the material. Do not sweep it or vacuum it up. Do not store belongings in the attic.


If work is planned that involves these areas, for example installing pot-lights in a room below the attic, send a sample of the vermiculite to a private lab. Send several samples, and use a lab specializing in asbestos analysis. If it is found to contain asbestos, or if you just assume it does, precautions should be taken. The safest approach would be to have the insulation in the affected areas removed by a qualified environmental contractor.



For smaller jobs, it may be sufficient to isolate work areas with temporary barriers or enclosures to avoid spreading fibres, use disposable protective clothing, and use proper respiratory protection. An important note – disposable respirators or dust masks are not appropriate for asbestos. Again, it is best to consult a qualified contractor.

The Janka Hardness Scale


Hardwood flooring is one of the best decisions you can make when it comes to interior home design, as it is a product that never goes out of style. It’s easy to assume that all hardwood flooring is the same when it comes to durability, but this is actually quite far from the truth. Hardwood’s actual hardness is measured by something called the Janka hardness scale. Let’s take a look at what the Janka scale is and how it works.


What is the Janka Hardness Scale?




The Janka hardness scale is a way of measuring the hardness of a given piece of hardwood. It was invented in the year 1906 by an Austrian wood researcher named Gabriel Janka, and it is an adaptation of the Brinell hardness test for metals. In order to better understand the Janka scale, you first need to know how the Brinell test works. The Brinell hardness test is used to test metal materials that are too coarse or rough to be tested by other means. The test involves a steel ball with a 10mm diameter being pressed into the material’s surface under 3,000 kgs of pressure. The resulting indentation is then examined to determine the hardness of the material.


How Does the Janka Hardness Scale Work?





The Janka hardness scale works in a very similar way to the Brinell test. It measures the pounds of force (lbf) it takes to drive an 11.28 mm diameter steel ball halfway into the surface of a slab of hardwood. A test done on the surface of a board, perpendicular to the grain is called a test of “side hardness”, while the same test being performed on the cut surface of a stump is called a test of “end hardness”. Every hardwood board will not yield the same test result, seeing as the hardness of wood varies with the direction of the wood grain, and will be different from one board to another. While durability issues come up when we look at different types of wood grains, there is usually not much deviation when it comes to differences in separate types of wood material, as estimates usually find the difference to be about plus or minus 10%.


Why is a Janka Hardness Rating Important?





Hardwood flooring is a big investment and will typically cost you a pretty penny, so you’ll want to make sure you are getting top quality wood that is not going to deteriorate or wear down after a few short years. While wood with a low Janka rating can still serve you just fine, it is only going to do so if you live a quieter lifestyle that does not involve your home seeing heavy foot traffic. If you have children and/or pets, try to find hardwood with a higher Janka score. A Janka hardness rating is going to give you a great indication of what kind of wear and tear your hardwood is going to be able to handle, helping you make a smarter decision when it comes to making a purchase.

Differences Between Engineered Wood Flooring vs. Hardwood Flooring



Engineered Wood Flooring vs. Hardwood Flooring


Engineered hardwood flooring sure has made a name for itself. Some people won't even look it's way, preferring traditional hardwood flooring, but there are of course advantages to both. What advantages does engineered flooring have over regular wood flooring you ask? Let's look at both sides of the equation and compare these two types of flooring so that you get a good look at the complete picture.

Engineered Harwood Flooring


First of all, engineered hardwood has a better reaction when it comes to both temperature and humidity. There are many reasons why companies prefer engineering flooring, it can be built and modified to be longer-lasting, more durable, and more cost-effective than some of its contemporaries. That's not the end of the story, however, so let's take a look at more of the differences.



Hardwood Flooring

In order to install Hardwood flooring, it is required that the floor be nailed into the ground. This is not the case with engineered floors however as glue can be used, or in some cases, staples. So far, we are painting a picture together that highlights engineered flooring as the winner of this battle but there are still two sides to this story. 

Let's say that you have been using a hardwood floor for over 20 years in your home. The chances are that by then it may start to lose its original finish. A tremendous benefit to Hardwood floors is that they can be easily sanded and refinished. This is not the case with engineered wood floors as the amount of true wood surface that on has to work with is limited in comparison.

Hardwood flooring will typically cost more money than its engineered counterpart. However, this is not always the case as there are many different kinds of materials that can be used to construct an Engineered Wood floor. One of the benefits of Hardwood is that it has a reliable material that one can expect to last for decades on end. This is not to downplay engineered hardwood, however, as there are many brands that offer tremendous quality and value for the product.





Now you know have a little more knowledge on what you can expect from both types of flooring, you may see why engineered flooring is making such a splash in the market. With more flexible installation options, an engineer’s design palette and reliable companies backing the product, we believe Engineered Floors offer something of great substance and value to the consumer.

At the end of the day however both hardwood and engineered wood flooring both have many advantages and neither is strictly better than the other. Different situations call for different types of flooring and what matters most is choosing the ideal product that will not only help your floor but also make you happy. Flooring is a big decision and there should be no bigger criteria than customer satisfaction.
