Hard and soft woods

Hard and soft woods

There is a strong relationship between the properties of wood and the properties of the particular tree that yielded it. The density of wood varies with species. The density of a wood correlates with its strength (mechanical properties). For example, mahogany is a medium-dense hardwood that is excellent for fine furniture crafting, whereas balsa is light, making it useful for model building. One of the densest woods is black ironwood.

It is common to classify wood as either softwood or hardwood. The wood from conifers (e.g. pine) is called softwood, and the wood from dicotyledons(usually broad-leaved trees, e.g. oak) is called hardwood. These names are a bit misleading, as hardwoods are not necessarily hard, and softwoods are not necessarily soft. The well-known balsa (a hardwood) is actually softer than any commercial softwood. Conversely, some softwoods (e.g. yew) are harder than many hardwoods.

Color

Color

In species which show a distinct difference between heartwood and sapwood the natural color of heartwood is usually darker than that of the sapwood, and very frequently the contrast is conspicuous (see section of yew log above). This is produced by deposits in the heartwood of chemical substances, so that a dramatic color difference does not mean a dramatic difference in the mechanical properties of heartwood and sapwood, although there may be a dramatic chemical difference.

Some experiments on very resinous Longleaf Pine specimens indicate an increase in strength, due to the resin which increases the strength when dry. Such resin-saturated heartwood is called "fat lighter". Structures built of fat lighter are almost impervious to rot and termites; however they are very flammable. Stumps of old longleaf pines are often dug, split into small pieces and sold as kindling for fires. Stumps thus dug may actually remain a century or more since being cut. Spruce impregnated with crude resin and dried is also greatly increased in strength thereby.

The wood of Coast Redwood is distinctively red in color

Since the latewood of a growth ring is usually darker in color than the earlywood, this fact may be used in judging the density, and therefore the hardness and strength of the material. This is particularly the case with coniferous woods. In ring-porous woods the vessels of the early wood not infrequently appear on a finished surface as darker than the denser latewood, though on cross sections of heartwood the reverse is commonly true. Except in the manner just stated the color of wood is no indication of strength.

Abnormal discoloration of wood often denotes a diseased condition, indicating unsoundness. The black check in western hemlock is the result of insect attacks. The reddish-brown streaks so common in hickory and certain other woods are mostly the result of injury by birds. The discoloration is merely an indication of an injury, and in all probability does not of itself affect the properties of the wood. Certain rot-producing fungi impart to wood characteristic colors which thus become symptomatic of weakness; however an attractive effect known as spalting produced by this process is often considered a desirable characteristic. Ordinary sap-staining is due to fungal growth, but does not necessarily produce a weakening effect.

"It's a horribly complex and ill-designed system that's going to be good for some people - 

mostly people with lower incomes - but for a lot of people, it's not going to be good for them," 

said Jeff Francisco health insurance agent who supports universal coverage but believes the law doesn't go far enough to help consumers and curb costs."Every plan is going to cost more than what I pay now. And what I pay now is ridiculous," said Ross, 47, who owns a cat-sitting business called y and pays more than $400 a month for her insurance. "It's a great thing for some people, but it's certainly not helping me."

the Affordable Care Act because she was hoping to get a better deal.

Ross is among the millions of Americage on their own, but must find new coverage because the health law has rendered their current policies outdated. But Ross, like many others, is not finding the plans sold through the Affordable Care Act to be particularly affordable.

Aside from a prohibition on denying coverage to people with pre-existing medical conditions beginning Jan. 1, the health law also rlicies sold next year to cover a minimum number of benefits. And that can add to the cemiums.

These include such mandamaternity and newborn care, substance abuse treatment, and dental 

But now that she's seen her options, Ross is disappointed. Turns out she earns slightly too much money to qualify for federal financial aid to help her buy coverage in the state's exchange, called Covered California. And because policies have to be upgraded to comply with the new law, her rates are going up nearly 10 percent.

Laminate Flooring Is An Alternative To “Real” Wood

If your home maintenance projects have led you to the conclusion that some of your finish floor covering needs to be replaced, then take a look at laminate flooring….it is durable alternative to wood that is worthy of consideration. This Raleigh Home Inspector installed some laminate flooring in his own home; after six years, its performance and durability are proving to be quite satisfactory.

(ARA) – You love the look of natural wood flooring but are afraid to install hardwood because you know the floor will take a beating from the kids, dogs and the heavy day-to-day traffic all too common in modern family life.

But you don’t have to sacrifice high style looks for boring sensibility when considering a new flooring option in your home – not if you choose laminate, that is.

Today’s best laminates combine the realistic grain and texture of wood with high durability and scratch and indentation resistance that “authentic” wood floors don’t provide, according to Jeff Katz, director – laminate for Tarkett Residential, a leading provider of innovative and sustainable flooring. And not only are today’s laminates available at a fraction of the cost of real wood floors, but they’re right in sync with the latest designs.

“There’s always a new decorating trend around the corner,” Katz says. “It’s imperative for manufacturers to respond to market demand, keeping up with the most up-to-date trends to ensure consumers are getting the latest in style and design, as well as technology.”

One such line is Tarkett’s Trends laminate, a durable new collection featuring eight of the hottest flooring designs, including Old World-inspired antique-stained planks and soft, hand scraped wood grains. Colors and styles in this line will continually rotate out with new introductions to give homeowners the newest, most popular looks in flooring, ultimately providing them with the high style of premium wood floors without the fuss.

“That’s the beauty of laminate products,” Katz says. “They’re the new normal – great-looking products that deliver great performance at a great value.

When shopping for laminate products consumers should look for flooring that is engineered with sturdy inner core board layers – preferably ones that deliver high impact resistance (at least an IC3 rating). This type of rating helps provide excellent indentation resistance, and when combined with highly rated top surface protection (AC3 or better) kids and pets can run and play freely on laminate floors without making a dent or marring up the surface’s good looks. As a result, laminate flooring is so durable versus real wood products that some laminates come with up to a full lifetime warranty.

What’s more, creating a laminate flooring transformation in your home is a relatively simple DIY project. Many of today’s new laminate floors come in easy-to-install planks that simply snap together without the need for messy glue or nails to pound. Laminates can even be used over several types of existing flooring, often eliminating the need for costly sub-floor preparation.

“Consumers now have the choice of selecting laminate floor innovations that provide excellent performance and value, while also reflecting and accommodating their changing tastes,” Katz says. “Laminate flooring solutions keep up with their day-to-day life. That’s something we know will never go out of style.” For more information about the latest trends in laminate flooring, visit www.tarkettna.com.
