Difference between Hemlock and Douglas fir lumber

Hemlock Fir vs. Douglas Fir - by ColdAudio @ LumberJocks ..

  1. The Douglas Fir is a more defined species, but is still not a real Fir tree. All Fir trees are of the Abies genus. Douglas Fir is of the Psudotsuga genus (notice kinda Hemlock not kinda Fir) It is the second tallest tree in North America and grows along the eastern coast and comprises of most of the Fir lumber in the US
  2. With hemlock it's a bit dependent on species, mountain hemlock needles encircle the branch more than western hemlock. Both species will have needles growing all around the branch on more immature twigs and foliage but once a western hemlock gets growing it will have needles clearly growing flat out from the branch
  3. Hemlock. Hemlock is a great economical wood for country homes and barns. It is pale in color and naturally develop a richer appearance over time. It looks great rough sawn and hand hewn. Hemlock is very strong, has a long grain and is a renewable resource. It is resistant to rotting and it is also much less expensive than Douglas fir
  4. Compare Properties of Canadian Wood Species Few places on earth can match the diversity and richness of British Columbia's (B.C.'s) forests. Canadian wood offers five wood species: Douglas fir, western hemlock, western red cedar, spruce-pine-fir (SPF), and yellow cedar. Each of these species have unique features which they bring to the table
  5. Conifers with leaf stalks called petioles will be bald cypress, hemlock, and Douglas fir trees. 1. of 3. Identifying the Major Firs. with small differences between them
  6. g applications. Compared to other species, Hem-fir is lighter in both the color and the weight, but this does not make it any less stronger
  7. Mountain hemlock grows between 125 and 175 feet in the Pacific Northwest, while the rest of the hemlocks are in the 50- to 100-foot range. Many fir species, such as white fir (Abies concolor) and noble fir (Abies procera), commonly grow between 100 and 150 feet tall

The designation is Hem/Fir covering a broader range of harvested specieas mixed in same load, much the same wauy that SPF does ( spruce, pine, fir) it stands for hemlock and fir mixed. The H/F mix is slightly more brittle than the doug fir and definitely less strong if you were looking at roof raters or joists, but it is fine for stud materials. DOUGLAS FIR is a straight grained and resilient timber with high strength to weight ratio as well as quick availability and ease of use. Hem Fir is light in color varying from a creamy, nearly white to a light, straw-brown color Hem-Fir is a species combination of Western Hemlock and the true firs (Noble, California Red, Grand, Pacific Silver and White fir). With strength properties slightly below Douglas Fir-Larch, this is an extremely versatile species group and useful for multiple, general-purpose framing applications There are easily identifiable differences in the leaves, cones and seed, even in silhouette. Looking at the grain of western hemlock vs amabilis fir shows their distinction clearly with a trained eye. I agree the average urbanite would have difficulty if they don't work with wood

how to tell the difference betwen a douglas fir and hemlock

Douglas Fir. As the second strongest softwood on out chart, Douglas fir is often found in structural framing. It's more immune to abrasive wear & tear than other softwoods, and it offers some resistance to decay. As a result, this is a common material found in large buildings and bridge trestles Eastern Hemlock. Eastern Hemlock timbers come from trees in New Hampshire and are milled to order. Eastern Hemlock is strong and durable enough for any projects. Hemlock Timbers provide homeowners great value for their projects and provide a unique look compared to Douglas Fir or Western Red Cedar Many woods have a substantial difference between the so-called earlywood (sometimes called springwood) and latewood (summerwood) in their annular rings, but in SYP (and douglas-fir, which we'll get to soon), it's dramatic. Simply put, the earlywood is fairly soft and the latewood is dense and tough Although some lumber may be traditionally stocked in green or kiln dried, it's important to note just because it is stocked one way doesn't mean you can't order it specific to your job. Take Doug Fir beams for example. Normally stocked green, it can be ordered in kiln dried usually in a day or two. It all just depends on what you are planning. Similarly, what is the difference between hemlock and Douglas fir? Both the Hemlock firs and the Douglas firs are large fir trees. They have soft needles with white lines. The needles are flat and not stinging or rigid

What Wood Species Should I Build With

We have broken down these differences into the 4 most common concerns we have received: Redwood heartwood vs redwood sapwood (and other redwood grade concerns) Finger jointed lumber vs redwood or cedar siding. Pressure treated Douglas Fir vs. Pressure treated Hemlock Fir. Fence board quality differences Heartwood vs Sapwoo What is the difference between hemlock and Douglas fir? Both the Hemlock firs and the Douglas firs are large fir trees. They have soft needles with white lines. The needles are flat and not stinging or rigid. Douglas fir are easily recognizable and so are Hemlocks Both red oak and white oak are harder than Douglas-fir wood. The Janka rating for red oak, the softer of the two oaks, is 1,220 pounds-force, while that for Douglas-fir is only 620, which is a little more than half. When it comes to general strength, oak is also the winner, but fir is more workable My experience as a carpenter was that Hem Fir, was mostly hemlock. Years ago maybe one in 100 boards were fir, now even less. And SPF was just about all spruce. Don't remember ever seeing a fir board in a stack. Now if you want douglas fir, the redish colored premium studs are doug fir. And lumber longer than 20' are usually doug fir

Top Lumber Species: Properties and Uses of Different

  1. Some other abbreviations that you may notice on the lumber is the mill code and the species mark. The following species are organized from strongest to weakest: Doug Fir, D Fir-L: Douglas fir (L=western larch) SYP: Southern pine; Hem, Hem-fir, H-F: Hemlock or fir; S-P-F: Spruce, pine, or fir; Kiln-dried wood moves less and is preferred for.
  2. Douglas fir is very common in Dutch forests, sometimes more common still than the Norway spruce. Hemlock firs are not often seen in forests, but nevertheless you see them here and there. Douglas fir are easily recognizable and so are Hemlocks. The different Hemlock species are quite impossible to keep apart
  3. Hemlock is locally widely used for raised garden beds, fencing, and barn construction and repair. There is no guarantee as to how long the wood will last in the ground, but in the right conditions, some people report that it lasts 5 to 7 years. There is enough of a price difference between the hemlock and cedar or fir, that it is locally preferred wood for general outdoor and farm use

Lumber Grading - Construction Lumber In order to help you determine what lumber you need for a specific building project and what grade you are receiving, a grade stamp is placed directly on the softwood lumber that includes information about the lumber's grade, moisture content, species, and other characteristics. To the left is an example of a grade stamp with each part numbered and defined Fir wood can go either way and be ideal for use in construction or shoddy and undesirable, depending on the species. Douglas fir woods are strong and ideal, with straight grains that are the result of long, straight trunks. Their wood is resilient and therefore a favorite choice for many people in various trades

Doug Fir or Hemp Fir?? - Fine Homebuildin

I found that an 8X12X24ft #1 grade douglas fir beam would handle the same load at 1/3 less cost to the lam. The beam has been in place for 13 years now with no perceptable deflection. There was some twisting, but that's the way trees are. In short, the doug fir handles loads well-can't tell you about spruce Grand Fir (Abies grandis) The grand fir is an evergreen true fir. True firs, (Genus Abies) are so named to distinguish them from Douglas firs and a number of other pretenders.. Medium to large trees, often 150-200' tall. Trees tend to have narrow shape and rigid upright or horizontal branching Species like hemlock, Douglas fir, western red cedar, or redwood. Is One Better than the Other for Wood Ceilings? Sometimes there's confusion about one being more premium than the other, but interestingly some softwoods are technically harder, more dense, and more durable than some hardwoods Next up is the difference between green lumber and kiln dried (KD) lumber. What is Green Lumber? Green lumber refers to lumber that has a high moisture content - freshly harvested logs are considered to have a moisture content (MC) of 100%. Once harvested and sawn into lumber, the wood begins the slow process of air drying

Lumber is stamped after it is milled and prior to being pressure treated. Pressure treated lumber commonly is end-tagged with an information label before leaving the plant. The stamp identifies: Wood Species. D Fir-L or Doug Fir for Douglas fir or larch (L) SYP for Southern yellow pine. H-F, Hem-fir, or Hem for hemlock-fir or hemlock One is location. Fraser fir (or she balsam) is found on the highest mountain tops of the southern Appalachians between Virginia and Tennessee, generally above 4000 ft and up to 6,600 ft. Hemlock does not usually grow above 4900 ft., so it is absen.. What is the difference between a Douglas fir tree and a noble fir tree? Most folks find it difficult trying to choose between a Douglas fir and a noble fir tree for their Christmas tree. The main difference between the two is that the noble fir tree has more weeping-like branches, but they are quite sturdy, making a great choice for heavier. The closer together grain lines are, the more strength and stability there is to the wood. Pine tends to have broad grain lines that wander, and if not properly prepared and dried the soft wood between those grain lines may expand and contract, causing cupping and twisting. Douglas Fir on the other hand, features a tight, flowing grain pattern.

What is hemlock fir lumber? - AskingLot

The reason for this is that most of the wood that is pressure treated is Hem-Fir. It is classification of wood that includes both Western Hemlock and Amabilis Fir. These are good building materials, but do poorly if left outdoors untreated. Hem-Fir is very common, and grows well in most of British Columbia's climates The weight of wood varies by the species of wood and the moisture content of the lumber. Green lumber will weigh significantly more than kiln dried boards due to its higher density. Find Wood Density. To find how much wood weighs start by finding the density of the wood. Use the wood density chart below to find the density for different species. pine, Douglas-fir, ponderosa pine, Sitka spruce, western hemlock, and eastern hemlock is examined in bending strength of beams and joists and crushing strength of short columns. The principal purpose is to check assigned working-stress values against actual observed breaking strengths. Working stresses are compared with the 2 percent exclusio Look for the number of needles that come out of the same spot on a twig. If a twig bears needles in groups of two, three, or five, you can safely call it a pine. If the twig carries its needles singly, it's a good bet you've got a fir or a spruce. Pull off a needle, and roll it between your fingers

If wood strength and hardness matter to you, choose Douglas-fir wood over whitewood. Fir is harder and stronger than pine, spruce or hemlock, and it's less likely to have knots or other blemishes. It may be more expensive but probably not as expensive as a hardwood like oak unless it's clear fir Hem-Fir is a species combination of Western Hemlock and the true firs (Noble, California Red, Grand, Pacific Silver and White fir). Being only slightly below DF-L (and above DF-S) in strength properties, this is an extremely versatile species group and useful for multiple, general-purpose framing applications

Douglas Fir vs. Spruce vs. Framing. I am building a workshop that is 20′ x 30′. I was planning on using 2x12x20′ Douglass Fir at 12″ on center for the joists for the second floor. The problem I have is that no one in my area carries Douglass Fir of that size. One place had Spruce, another has framing lumber Douglas fir is another type of wood commonly used in garden planter boxes and raised bed assemblies. According to the writers from Greenhouse Today, fir is a hardy wood that can last 10 to 15. Douglas fir firewood is arguably one of the most popular softwoods to burn especially if you live in an area where these trees are abundant. Let's face it, everyone would love to burn seasoned oak, madrone, maple or some other popular hardwood but these trees don't grow everywhere. In fact, a lot of people who heat with wood live in a area where softwoods dominate the landscape Douglas fir is seen as a first-class wood for the manufacturing of sash, doors and windows. The wood is also used for a wide variety of products including general millwork, furniture, cabinets, veneer, vats, ship and boat construction, transmission poles and marine pilings, and for structural purposes including laminated arches and roof trusses

We now offer other softwood lumbers such Alaskan Yellow Cedar, Port Orford Cedar, Douglas Fir, Ponderosa Pine, Lodgepole Pine, Sitka Spruce, Western Larch and Hemlock The words fir and for are often confused because of their similar spelling. But what is the difference? For means towards when used as a preposition.. Fir means any conifer of a variety of genera, especially a Scots pine, Pinus sylvestris or a (Abies) when used as a noun.. Out of the two words, 'for' is the most common. It appears about 1953 times more frequently than 'fir'

What is Hem-Fir? - Sherwood Lumbe

  1. The occurrence of wetwood in balsam fir is a problem in the drying of sawn lumber: drying time increases and moisture content of dried lumber is heterogeneous. Permeability may be used as an.
  2. Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material - a natural composite of cellulose fiber
  3. Academia.edu is a platform for academics to share research papers
  4. Spruce, Fir, or Hemlock? One of my main goals in creating the Sibley Guide to Trees was to apply modern methods of bird study to tree identification. This meant looking at trees at a distance and trying to figure out what, if any, differences would allow me to distinguish species quickly and reliably in just a glance
  5. Despite the name Douglas Fir, the tree is actually part of the Hemlock family. When properly dried, Hemlocks provide extremely stable lumber that resists checking or twisting. Even when constantly exposed to heat and moisture, such as in saunas, Hemlocks retain their smooth texture and stability
  6. Denotes the wood's species or a group of species with similar strengths. (See Wood Code, below). While all species are graded at the same four levels of strength and appearance, they are not equally strong.

Douglas Fir. Pound for pound, Douglas Fir is one of the strongest western soft woods. This wood is used in the manufacturing of more products than any other lumber species. This strong, reliable and workable wood is perfect for use in many projects. It's lightweight and easy cutting properties make Douglas Fir great for home improvement The Pinaceae family is very large and contains some of the most commonly foraged conifers, such as pine, fir, Douglas-fir, spruce, hemlock, and true cedars. Pine Tree Identification Pine trees ( Pinus spp.) have needles that are bundled in clusters of 1-7, with 2-5 being most common, depending on the species Hemlock. Hemlock is cheaper and is therefore used in some products to reduce costs. It is acceptable to use and is a relatively clean wood. It does tend to crack a bit more than some other woods due to its hardness and the prevalence of knots in the grain. It will also become hotter to the touch due to its hardness

Distinguishing Western Hemlock from Amabilis Fi

  1. Fir tree identification. Balsam firs grow to between 46 and 66 ft. (14 - 20 m) tall with some of the tallest trees reaching 90 ft. (27 m). The balsam fir is identified by its flat needles that grow to 1.18 (3 cm) long. Cones are dark purple to brown and grow to between 1.5 and 3.14 (4 - 8 cm) long

For example, acquiring old growth Douglas fir in the 6 by 12 dimensions that were commonly used 100 years ago are expensive and rare to come by, if at all, from today's lumber mills. This is due to a number of factors, including present availability or laws preventing the harvesting of existing old growth trees There's a big difference between western hemlock which comes from the coastal mountains in Oregon, Washington, and British Columbia and eastern hemlock which comes from the northeastern states and Canada. Western hemlock is sold as premium structural lumber in douglas fir, hemlock, larch mix. It's strong, stiff, and durable Hemlock and Spruce. About 20% of our logs are either Western Hemlock or Sitka Spruce. The lumber from both species is so light in color that it is often called white wood. The wood is a uniform light tan, with little or no difference between the heartwood and sapwood. Sitka Spruce is even lighter in color than Western Hemlock Plywood, lumber, railroad ties, flooring, fence posts and even furniture are a common use of Douglas fir. Douglas fir has been commonly used as a Christmas tree since the 1920s because it is typically less expensive than other species. There are many different firewood species to choose from 1 x 8 Net 3/4 x 7-1/4 wide. pictures represent grade of wood - no the width. Douglas Fir is one of the most common used woods in the Pacific Northwest. Its great for furniture, trim-work, cabinetry and doors. With right finish you can use Doug Fir inside or outside. It's an incredibly valuable commercial timber, widely used in construction.

Softwoods have been exported from the United States for over 400 years. Today, America is recognized worldwide as a sustainable source of top quality products. The simple cell structure of softwoods' long, uniformly packed fibers gives them a high strength-to-weight ratio, making them flexible and capable of bearing heavy loads. American softwoods have the strength [ Spruce-Pine-Fir (South) This species combination, classed as moderately strong, is cross-continental in origin. Because of similar design values, the combination includes Engelmann and Sitka spruces, and Lodgepole Pine from the West, along with Balsam Fir, Jack Pine, Red Pine and several eastern spruces from the U.S. Northeast Other conifers include bald cypress, cedar, Douglas-fir, hemlock, pine, redwood, and spruce.

  1. e timbers, house logs, posts and poles, fencing, flooring, pulp, and furniture
  2. Because of its slow early height growth, associated species such as western hemlock, Douglas-fir, and noble fir initially overtop Pacific silver fir when grown in the open. After the initial overtopping, on many sites Pacific silver fir appears to outgrow and become taller than western hemlock after 100 years (19)
  3. The term timber describes sawn wood that is 140mm (5-1/2) or more in its smallest dimension. There are two in the Douglas Fir-Larch and Hem-Fir species combinations; however S-P-F and Northern species Unlike Canadian dimension lumber, there is a difference between design values for No.l and No.2 grades for timbers

This is your assurance that the panels purchased meet or exceed performance requirements

Douglas-fir. Douglas-fir is among the world's chief timber trees, valued for its prolific growth and solid performance as lumber. In the wild, it grows across a broad range in western North America as two distinct varieties: coast Douglas-fir and interior Douglas-fir Cedar Soffit Lumber Products Western Hemlock. Western Hemlock is used for interior and exterior construction, cabinets, furniture, flooring, paneling, doors and millwork. Douglas-Fir. Douglas Fir is one of the strongest woods in the world. It is an ideal choice for aesthetically and structurally demanding applications. It is used. Douglas Fir - A soft wood, Douglas Fir is offered in two different grains. The mixed grain truly celebrates the wood's natural feel and depicts a Southwest style with a creamy, sun-washed tone. You can also paint it a warm white to create a Bungalow style In strength hemlock doesn't compare to Doug fir, for example, and the rise in this material's use is tied in part to the reduction (and increased cost) of traditional structural lumber (i.e. Doug fir). Hemlock tends to hold its knots more tightly but even so I would find clear material Fir is a group of tree species related to pine, just as spruce, hemlock, tamarack, and other coniferous trees are. As far as what the differences are between fir and pine, I live in the east and we don't have much in the way of fir where I live, so I can't tell you what the differences are in living trees

Douglas Fir is what is pressure treated, redwood cedar or oak would survive, pine most likely would be gone in a couple years. Pressure treated lumber is to protect from insects and mold it can still get dry rot Eastern Hemlock. Eastern Hemlock timbers come trees in New Hampshire and are milled to order. Eastern Hemlock is strong and durable enough for any project.

This study used the second-growth plantations of Douglas-fir, western hemlock, Sitka spruce, and western redcedar of the Ministry of Forests Experimental Project 571 (species-espacement trial established in 1965-1966 on southern Vancouver Island) to take a preliminary look at the effects of different conifer species on collembolan, oribatid. What about the difference between a fir and spruce tree? Again, needle types are the key to identification. Spruce needles have four sides and they roll easily between your fingers. Fir needles are flat and if they don't roll easily, chances are it is a fir tree, not a pine or spruce. Identifying Spruce, Pine or Fir Based on their Needle 1996). Consequently, although they vary highly in composition and structure, Douglas-fir - western hemlock forests are mostly in early seral stages (Barbour and Billings 1988). Douglas-fir wood is valued for its superior mechanical properties, making it most useful in building and construction (Barbour and Kellogg 1990)

The western type of white fir looks a lot like red fir (true red fir, not Doug fir), and the best way to tell the difference between white and red fir is to twirl the needles between your fingers. Red fir needles are square and will roll easy between your fingers, whereas white fir needles are flat and will not B.C.
