Around for centuries, …..has always been a popular, practical and stylish choice
.
* …..is used for flooring, wall cladding and furniture making
wood
wood types
hard and soft
Types of Trees:The word deciduous means to “fall off”, and every autumn
these trees shed their leaves.
* Most deciduous trees are broadleaved, with wide, flat
leaves. take anything up to 100 years to fully grow.
Deciduous:
Types of Trees An evergreen plant/tree is a one that has leaves
throughout the year that are always green & don’t fall out.
* Take as little as 25 years to fully grow
. Evergreen
How the tree was cut (plain-sliced and
quarter-sliced) Different Cuts present different grain.
- Material makeup (cuts):
WOOD SPECS:
Characteristics
- Shrinking and Swelling: Response to moistures
- Oxidation and Fading: when wood changes color over time. E.g. Cherry will darken over time. Or other bleach with sun
- Natural color and grain: Some have pronounce grain like Walnut others have light and unified grain like Maple
Mahoganyor purple like purple heart - Figuring: Natural disturbing to the natural grain. More expensive.
….refers to lumber that has been cut from an Evergreen tree.
* …are widely used as a basic construction material but are less durable than hardwoods.
* Flexible, lighter in weight and less dense than most
* Can be used across a broad range of internal and external
projects : from furniture and flooring to decking, landscaping and structural applications
.
Softwood
have a wide range of applications and are found in building components (e.g., windows, doors and
furniture)
Softwood
- Comes from Deciduous trees.
- ..generally offer a strength and
durability. - Grow at a slower rate and require longer drying times, these factors drive up the cost of the wood
(takes between 1 – 2 years)
Hardwood
most likely to be found in high-quality furniture
Hardwood
Hardwood VS Softwood
Comes from Deciduous trees
found in high-quality furniture,
Beech, mahogany, maple, oak,
Most hardwoods have a higher
density
more expensive
a slower growth rate.
Comes from evergreen trees which usually
have needles and cone
About 80% of all timber comes from
softwood. -wide range of applications
& found in building components.-(e.g., windows, doors and furniture
Pine, redwood, spruce, and yew
a lower density
less expensive
faster rate of growth.
: refers to thin slices of hardwood that are glued and pressed softwood. onto core panels of It can be used for a variety of purposes, such as
doors, tops and side panels for cabinets, wood flooring and more
Wood veneer
is a remarkably strong composite typically
made of thin veneers of wood( hard or soft)
* They are sandwiched together
with binders, pressed
and heated
.
Plywood
used in many applications that need quality, high-strength sheet material. This includes
,
Furniture, Kitchen Cabinets, Wall/Ceiling Claddings.
* The edges also need to be covered with suitable pieces of wood.
Plywood
is an engineered wood-based sheet material made by bonding together
wood fibers with a synthetic resin adhesive.
cheaper than plywood.
* The surface smooth
a great surface for painting
very consistent and easy to work with.
Medium Density Fiber board (MDF)
A plank is timber
parallel faces
that is flat and rectangular
with
that are higher and longer than wide.
Engineered wood plank layers
1.Finishing material
2.Face veneer (hardwood)
3.Core (softwood, MDF, etc)
4.Backer venee
t
Wood planks are used for flooring or wall
paneling.
* Sizes vary from 6
cm to 25 cm in width and 2
to 5 cm
in thickness.
The lengths
are going to be 70
vary but most likely, they
to 100 cm.
* Installation: allow for contract and expand (
cm
).
* Floor: Tongue
1 to 2
and Groove technique. It solve
shrinking problem.
* Wall: Board and batten
(revered)
t
Wall: Board and batten (revered)
* board and batten basically just means putting wood/
strips
on your wall in a pattern or design!
* It is an affordable way
mdf
to give a space character, add a focal
point, and elevate your space
t
Even if you cut a piece of wood from one tree
,
you can have different appearance
t
Different Types of Lumber Cuts:
- Plain sawn
- Quarter sawn
- Rift sawn
- Live sawn
WOOD SPECS: Shrinking and Swelling
Shrinking and Swelling
* Solid Wood shrinks and swells in response to
moisture.
* When the air is humid,
swells
woodadsorbs moisture and
; when the air is dry,
and shrinks.
woodloses moisture
* Shrinkage and swelling of wood cannot be prevented
only the rate of shrinking and swelling can be
slowed by
Coatings.
t
Cause color changes in some woods, usually
a fading of the color
Oxidation and Fading :
- It is a pattern of fibers seen in a cut surface of wood
- It has two componentscolor & physical texture.
A. Color
*Why has wood variation in grain colors?- Because of different time/ seasons of growing.
B. Physical texture
.
*Some types of wood have open grain “coarse-grained”
pattern, while others have close pattern “fine-grained“
t
. Physical texture
* Open grain “coarse-grained” pattern, so you feel its
texture.
* Open grain is used to describe a piece of wood with
large grain. The uniqueness of a piece of wood is defined
by many characteristics such as
color, hardness and grain.
* Close pattern “fine-grained”, so it gives smooth feeling
* Fine grain refers to the types of wood that have very small,
tight lines in the wood
