What is Timber ?
 Simply the name suggest that the flooring made of timber i.e wood
is called timber flooring.
 Wood is a common choice as a flooring material due to its
environmental profile, durability, and restorability.
3

Why Timber ?
 Long lasting i.e more durablity.
 Easy to clean.
 Easy to resurface.
 Soft for foots unlike concrete and tiles.
 Gives better look.
 Low maintainence.
 Soft for falling objective
4

History
 It wasn't until the Barouque Era (1625-1714) that wooden floors
became elegant, starting with the French parquetry and marquetry
patterns.
 They were then hand scraped of their overwood, scrubbed with
sand, stained and polished.
5

History
During 16th century
 The first wooden floors in colonial America were wide, thick planks
cut from the continent’s abundant old-growth forests.
During 18th century
 During 18th century wooden were lest bare end kept untreatable
after installation.
6

History
 It was kept on the action of time i.e as the time goes the timber gets
treated according to requirement.
Before 19th century
 Decorative flourishes :As decoratively painted interiors became
popular in the 19th century, this technique was applied to wood
floors, too.
Recent trend
 New trends include many of the types, shades,techniques.
 Wooden flooring is the symbol of royalness and wealthness too.

Types of flooring
 Strip flooring
 Wood block flooring
 Parquet flooring
 Plank flooring
11

Strip flooring
 They are narrow and thin strips of timber
 jointed by tongue and groove joints
 Normal strips 6 to 10 cm in with and 2 to 2.5 cm in thickness are
used
12

Wood block flooring
 This consist of short but thicker wood blocks which are laid in
suitable designs over a concrete base
 This block are properly joined together with the grains exposed
 Size varying from 20*8cm to 30*8cm thickness 2 to 4 cm are used
13

Parquet flooring
 This is similar to block flooring except thin blocks are supported on
sub-floors
 The blocks are laid by means of hot glue in desired pattern and then
nailed with panel pins
 Popular in this days
14

Plank flooring
 In this type of flooring wider planks are used
 Jointed by tongue and grooves
 Normally Width
15

Joists & Types Of Joists
 Truss
 Purlin
 Girder
 Rafter
16

Rafter
 A rafter is one of a series of sloped structural members (beams)
that extend from the ridge or hip to the wall plate, downslope
perimeter or eave, and that are designed to support the roof deck
and its associated loads
17

Truss
 A truss consists of typically straight members connected at joints,
traditionally termed panel points. Trusses are typically composed
of triangles because of the structural stability of that shape and
design.
18

Purlin
 A purlin is any longitudinal, horizontal, structural member in a roof.
19

Girder
 A girder is a support beam used in construction. It is the main
horizontal support of a structure which supports smaller beams.
Girders often have an I-beam cross section for strength, but may
also have a box shape, Z shape and other form
20

Timber flooring
 Single joist timber beam
 double joist timber beam
 Frame triple joist timber beam

Construction Details
In this type of flooring timber planks of 20 to 25mm thickness and
width - 150 to 200
 A concrete bed of 100 to 150mm thick is laid.
 Wooden battens of 50 to 75mm thickness and trapezium in shape
are embedded in bed concrete at an interval of 500 to 700mm.
 Wooden planks are laid on the battens.
 Planks are connected to each other-
by tongue and groove joints.
 Planks are connected to battens by-
using screws.
38

Construction Details
 In this type of construction base concrete is first laid in 15 to
20 cm thickness over it, a layer of mastic asphalt is applied.
 Wooden block flooring is then laid over.
 blocks of size 20x 8cm to 30x8cm and
 thickness 2.5to4cm
40

Characteristics
 Durability . – it should be capable of resisting the actions of fungi,
insects ,chemicals .
 Toughness – it should be tough.
 Weathering effects –
 it should be able to stand -
reasonably the weathering effects.
 timber is bad conductor of heat .
44

Characteristics
 Variety. There are a lot of styles, colours and species of timber
flooring available.
 Affordable.--timber floor finish may last for up to 8 years.
 The cost of recoating a timber floor is more affordable.
 Timber is natural, hard wearing and when maintained and kept
clean it avoids carrying dust and allergens which promote asthma
and other respiratory problems.
45

Characteristics
 Ecological. Timber Floors are ecologically friendly. Since it is a
natural resource, timber is both renewable and recyclable
 Easy to maintain --Maintenance of timber floors is easy.
 Flexible -- Hardwood timber floors will always look good both in
contemporary and traditional interior design.
46

Advantages & Disadvantages
Advantages
 Being strong and durable wooden floor provides infinite benefits as
it is as beautiful as any other designer flooring.
 Timber flooring can withstand huge traffic without replacement and
minimal maintenance.
 It just needs to be re-sanded or re-polished to retain its original
luster and finish.
 Eco-friendly and natural material which hardly requires energy
during manufacturing.
 Timber is hypo-allergic which do not extract dirt and other allergens.
 Good insulator and hygienic
 Low maintenance
48

Advantages & Disadvantages
Disadvantages
 Expensive
 May loose its shine giving dull look
 Takes lot of time to set on the floor
 Sometimes slippery and dangerous

Sr No Type Application
1 BUTT JOINT Generally in Furniture as
relatively its weaker
2 DOWELLED
BUTT
The dowels inserted inside
enables the joint to be used
in excess load bearing units
3 DADO Used at T joints generally in
connecting joists with pillars
in a wooden construction
house
4 RABBET Used at L junctions
generally in furniture as the
bonding surface area is less
which disables higher load
taking capacity
50Types of common Joints and its uses

Sr No Type Application
4 DOVE TAIL Used at L junctions
generally in furniture
As well as in house
constructions; the
higher sticking
surface area enables
it to take much more
load
5 MITRED WITH
WOOD SPLINE
Used at L junctions
but the Spline
inserted inside
makes it much rigid
and tough that it can
relatively take excess
loads as compared to
other joints
51

6 MORTICE
AND TENON
Used at T joints
generally in
FURNITURES as
the tenon makes
the bond so rigid
that the joint can
take much higher
loads and makes
the furniture much
more durable
7 TONGUE AND
GROOVE
Very common used
joint as can be used
in variable functions
as straight joins and
other types of the
same
