PARTITIONS

Partitions have become today’s most mobile and flexible wall system as their secret is making it possible to divide one room into several different ones with incredible sound insulation.

Partitions are usually thin and light of construction. where the essential purpose is to serve as divisions.

Building a partition will not increase the actual floor area available within a house but by subdividing it more appropriately it can provide extra rooms which will make living in the house more enjoyable.

Whatever the purpose of the partition, a number of points need to be considered:

Lighting - natural daylight may not be necessary although it is often desirable. If an existing window is not going to be included in the partitioned off area, a new window could be added in an outside wall. Alternatively glazing could be incorporated into the partition to 'borrow' light from the adjacent room, this can easily be incorporated along the top of the partition.

Ventilation - although a window is probably the most common form of ventilation, it is quite possible to include an electrical extractor fan to ventilate the new area.

Electrics - often when a room is divided, it is necessary to change the ceiling lights. The existing light may need to be repositioned and a new light and switch may need to be added in the 'new' area..

Services -
Outlets may also be required on the partition for heaters, shower units etc.
Plumbing may also be required. The most obvious requirement is where the partition is being built to create a shown area.

Glass partitions:
Glass is very commonly used for partitions.
Usually used in offices, restaurants,workshops and also residences.
Many types of treatments are done on glass for it to loose its transparency.
Cause of which it can be used in bedrooms and bathrooms also.




Glass Blocks:

Now a days glass blocks are also used as partitions.

The standard size of one block is ,
7 ½” * 7 ½”
6 ½” * 6 ½”

They are usually joint by white cement.

One glass block cost around Rs 120 to Rs 130.



Rotating Glass Panels Used In A Partition:
Use of translucent panels which are fixed into stainless steel rods.

12 mm thick------rs.85/sq. ft
10 mm thick------rs 75
Glass block-120 to 130 rs
Adhesives used-
Araldite
Silicon
u.v. glow
Poloshing-
Crystal polish-rs10/running feet
Bewelling-rs 40 per running feet
Half round/full round-rs40 per running feet

Free standing metal room dividers:


These room dividers are fee standind i.e. assemblies not required.
Can be removed when not wanted.
Are portable.
Sound absorbing to some extent.
Full length aluminum hinges add strength and stability throughout the entire divider.


Room dividers can be locked together to form unlimited lengths.
Room Dividers will provide multiple and variable sized class or work areas without the limitations and costs of ceiling mounted track systems.


Room Dividers come in 6 heights ranging from 4' to 8'. The length of the divider depends on the number of panels you select. Available lengths are: 5'9" (3 panels), 9'-5" (5 panels), 13'-1" (7 panels), 16'-9" (9 panels), 20'-5" (11 panels), 24'-1" (13 panels).

Timber partitons :
Also known as stoolhings ,or stoothed ,stud or quarter partitions.
Consists of vertical members called studs or quarters.
2 main horizontal members known as head and sill.
Studs are stiffened by nogging pieces or noggings at vertical intervals of from 0.9 to 1.2 metre which are fitted more or less horizontally and tightly between the studs.
if provisions has to be made for a door the door posts should be sufficiently rigid to resist the impact of the door.



Plasterboard partitons:

Plaster board can be used to cover stud partition.
Consists of aerated gypsum encased in paper.
There are 4 types of plaster boards,
a) gypsum wallboard
b) gypsum lath
c) gypsum base board
d) gypsum plank
Available in plain and insulating grade.

Three types of joints which are used are:
Tapered edge
Square edge
Bevelled edge
Gypsum wallboard-
Ideally suited for direct decoration because the paper covering to one surface is smooth and ivory coloured.
Different sizes available: 2438mm x 1200mm
1829mm x 900mm
1219mm x 914mm
Available in two thicknesses 9.5 mm & 12.7 mm
It is secured by nails which has flat head and smooth shank.

b) Gypsum lath-
Narrow width plaster board.
Cheaper than wall board.
It has grey paper covering and characterised by rounded edges.
Sizes available: 406 mm x 1200 mm
406 mm x 1219 mm

Sizes available: 600 mm x (2350,2400,2700,3000) mm
Mainly used for encasement of steel columns and beams.




Aluminium frame partitions
The present concept of modular design in offices and commercial establishments has offered a wide scope of applications for use of aluminium extruded sections in door and partition.
The strength, low density, corrosion resistance and design flexibility of aluminium make it an ideal material for partitions.
The partitions can be so designed to have wooden panels at the bottom and glass on the top.
They can be built on site with very little disturbance to the masonry.
Being very light, these sections don’t add up much to the load on the structure.







WOOD-WOOL CEMENT PARTITIONS
The material consists of wood-wool (wood shavings) and ordinary cement.
Long shavings from 3 to 6 mm wide are coated with liquid cement, consolidated into slabs by means of a machine press, and then stored to mature.
The slabs are very light, can be easily fixed and sawn, and provide a good key to the plaster which is applied to the surfaces after fixing.
Their dimensions vary from 1800 to 4000 mm long by 600 mm wide by 50, 75 and 100 mm thick.
50 and 75 mm thick walls are more commonly used when the height does not exceed 2.4 to 3 m respectively for the cavity walls.



CLAY AND TERRA-COTA BRICK AND BLOCK PARTITIONS
THE COMMONEST TYPE OF CLAY PARTITION IS THE ORDINARY SOLID BRICK WALL OF 105mm {or 65mm IF LAID ON EDGE}
SUCH WALLS ARE RELATIVELY STRONG AND FIRE RESISTANT but THEIR WEIGHT PRECLUDES THEIR USE FOR PARTITIONS
HENCE CLAY BLOCKS WHICH ARE LIGHT ARE USED.
LIGHTNESS IS OBTAINED BY MAKING THEM HOLLOW.

Table giving the usual range of sizes in which clay blocks are made.


HEIGHT LIMITATION
62.5 WIDE BLOCK-HEIGHT SHOULD NOT EXCEED 3m
75 WIDE BLOCK-HEIGHT SHOULD NOT EXCEED 3.65m
100 WIDE BLOCK-HEIGHT SHOULD NOT EXCEED 6m
Height of one block corresponds to the height of three bricks plus two joints [{3*65}+{2*10}]
Blocks are built in cement mortar and are bonded in usual way with staggered vertical joints.
Advantages
Satisfactory mechanical strength, light, good heat insulation, fireproof, non-shrinkable and vermin proof.

Types of hollow clay blocks


A: smooth-faced block- faces being decorated as required

B: keyed block- deep sinking form a good key for plaster


C: rug face block- can be used for internal and external walls


D: six cavity load bearing block. Used as inner leaf of cavity wall


E: FIXING BLOCK.NAILS CAN BE DRIVEN DIRECTLY INTO THESE BLOCKS.




PRECAST CONCRETE BLOCK PARTITIONS
PRECAST CONCRETE BLOCKS ARE
-SOLID: FOR GENERAL BUILDING USE INCLUDING BELOW d.p.c LEVEL
-HOLLOW: FOR GENERAL BUILDING USE INCLUDING BELOW d.p.c LEVEL

CELLULAR: MAINLY FOR INTERNAL NON-LOADBEARING WALLS [i.e PARTITIONS]
THE BLOCKS ARE COMPOSED OF A BINDER WHICH IS USUALLY CEMENT, ALTHOUGH LIME IS ALSO USED, AND AGGREGATES LIKE NATURAL STONE, CRUSHED BRICK.etc

P.V.C. [POLY VINYL CHLORIDE] FLOORING]

INTRODUCTION
Polyvinyl chloride (PVC) is a major thermoplastic
material finding use in a very wide variety of
applications and products.
PVC's major benefit is its compatibility with many different kinds of additives, making it a highly versatile polymer. PVC can be plasticised to make it flexible for use in flooring and medical products.

Its compatibility with additives allows for the possible addition of flame retardants although PVC is intrinsically fire retardant because of the presence of chlorine in the polymer matrix.
Its good impact strength and weatherproof attributes make it ideal for construction products.
PVC can be clear or coloured, rigid or flexible, formulation of the compound is key to PVC's "added value".

Things to Do Before Installation
Verification of the installation date.
Ensuring the removal of all "breakables" from the room.
Determining who will remove furniture, appliances and the sub-floor, if needed .
Arranging for the disconnection of gas appliances and icemakers.
Determining if any change to the height of the floor require adjustments to doors in order for them to close properly.
Ensuring the removal of items in storage areas and closets where the floor is to be resurfaced.
Make certain drapes, wall hangings and pictures are removed from walls.
Verify that your in-home temperature is appropriate for installation.

PVC flooring is made of soft PVC, and other materials such as cork tiles may have a PVC coating. Types of PVC flooring are cushion vinyl, sheet vinyl and vinyl tiles, and contain phthalate softeners, which are released into the air.

PVC INTERLOCKING FLOOR TILES

PERFORATED TILES - ANTI SLIP These perforated tiles are ideal for creating a workspace that's clean, safe and functional. With a 1/4" hole, they're very easy to clean, as the perforations catch dust, dirt and other particles that are quickly removed with a vaccum. Size per Tile is 12 x 12 inches x 3/4 inch thickness. Border Strips are 12 x 2 1/2 inches x 3/4" thickness with Beveled Edges.

CUSHIONED TILES - SHOCK ABSORBENT These cushioned tiles offer unparalleled air cushioned comfort. Great for aerobics studios. This anti-fatigue comfort tile greatly reduces stress where work is conducted while standing, or where noisy machines that cause strong vibrations are used. Resistant to mold and mildew. Cushioned tiles make an ideal covering for damp and cold basement floors; are easily assembled, interlocking one to the other; and form a strong but cushioned floor surface with multiple applications.

MULTI LOCK VERSA TILE A Thermo-plastic rubber, (PVC), 20" X 20" X 5/16" thick interconnecting
tile is designed for extra heavy vehicle traffic, (fork lifts, etc.), as well as heavy foot traffic. Great for basketball and roller hockey courts. 3.75
lbs. per tile. Actual coverage of each tile is 19 5/8" x 19 5/8" or 2.67 Sq. Ft. The coin finish provides an anti-slip surface. A great
economical solution for new surfaces, or to repair old
worn out, cracked surfaces in warehouses, dock areas,
high traffic entrance areas, industrial workshops, sports
and leisure centers, arenas, schools, public buildings,
walkways. Available in smooth surface also for sporting courts.

RUBBER FLOORING
Rubber tile floors gives a room a high-tech look. Rubber flooring was once made from the milky sap of the rubber tree, but most rubber tile flooring is now synthetic or manmade. Rubber tile flooring is resilient, flexible and durable. Rubber flooring is resistant to burns and dents; it's built-in self-releasing wax allows some rubber tile flooring to self heal most scratches and abrasions. Rubber tile flooring comes in wet suit finishes, primary and pastel colors, and in industrial studded rubber sheet or rubber tiles.
Rubber Flooring is washable, easy to maintain & available in various designs like
Chip Rubber Flooring, Granite Rubber Flooring & Marble Rubber Flooring.
These floor coverings beautify the home & office. In kitchens, bars, and industrial
settings, rubber floorings with an anti-slip textured surface resists grease and
chemicals, and it rolls up for easy handling and maintenance. The rubber flooring
can be installed in stadiums and arenas, sports and entertainment facilities, schools
and universities, healthcare, commercial, office and retail facilities.

LINOLEUM FLOORING

What is Linoleum Flooring?
Linoleum is a highly durable, ecologically
friendly substance. It can last fifty years
and more and still be an excellent flooring.
In fact, it continues to become more durable
after installation due to the oxidation the
flax oil.
The original resilient flooring invented in 1863 is made from clay, cork, wood flour, linseed oil, resins, and pigments applied to a jute backing (tile has a dimensionally stable fiberglass backing).
Dubbed the "40 year floor" because of its durability, this all natural sheet (2.5mm thick 79" wide) and tile (2.5mm thick, 20" x 20") flooring is available in many exciting new colors.

Why is it better?
· No toxic off-gassing
· Highly durable and withstands heavy loads
· Non petroleum-based and biodegradable
Other features and benefits
· Cost effective because of long-life and low maintenance costs
· Adds to good indoor air quality; inherently anti-bacterial
· Easy to clean
· When heat-welded, seams are water-tight unlike vinyl composition tile (VCT)
· Inlays and heat-welding provide design flexibility
· Twice the indentation resistance of VCT
· Less costly to maintain and greater stain resistance
· Anti-static

Maintenance
Dry or wet floor method.

Price Comparison
The cost of linoleum flooring varies with many factors. The initial
cost of material is higher than vinyl composite tile but lower
maintenance and longer wear provide a better value.

Linoleum advantages
Linoleum is a beautiful surface that is available in a remarkable range of colors and patterns. Because it can be cut, linoleum lends itself to creative floor design with patterns and bands to create unique floors for every room in your home. It´s comfortable and resilient underfoot.
Linoleum is extremely durable and has a life expectancy of decades with a minimum of maintenance, which makes it ideal for high traffic areas. It´s water resistant so it´s a logical choice for kitchens, bathrooms, laundry, and mud rooms. It doesn't´t generate static electricity so it´s appropriate for offices too.
The color is integral to the flooring, so if you drop a knife you can repair the damage and reseal it. If it´s not too large a ding, it may even self-heal.
It is also characterized by being naturally anti-microbial. This makes it a good choice for schools and hospitals, and would be great solution in a child´s room, nursery, or playrooms. It´s easy to clean; generally sweeping and occasional damp mopping is about all that´s required.
In addition to using for floors, linoleum also makes nice countertops everywhere but where it may come in contact with food. Because it is finished with acrylic, it isn´t suitable for kitchen counters unless you use a chopping board or have a designated counter for food preparation.
The cost of linoleum usually runs about the same as high-end vinyl and is often comparable to wood flooring or carpet.

Linoleum disadvantages
Though linoleum is beautiful and durable, it has its weaknesses. It must be protected from moisture in the sub flooring, which makes it a poor candidate for basements or concrete sub floors. Armstrong recommends against using it in bathrooms, though Forbo uses it liberally throughout their sales literature. Read the manufacturer´s recommendations for installation to prevent voiding the warranty.
Nevertheless, linoleum is very common for bathroom installations. Because it is made of linseed oil, it is water-resistant; most vendors suggest adding a bead of silicone caulk as extra insurance to prevent water from getting to the sub flooring. Joints where the flooring meets the tub or shower would be the most likely candidates for sealing.
Some folks consider not being able to install it themselves to be a disadvantage too. Most manufacturers and vendors maintain that sheet linoleum should be installed by pros, though tile may be installed by do-it-yourselfers.

Linoleum tile installation
The following steps are an outline, but shouldn´t be considered a comprehensive guide for your linoleum tile installation.

Prep the floor. Linoleum tile can be installed over existing flooring if it is securely attached to the sub floor. If it isn´t, you´ll need to rip it out. However you approach it, the surface to which you intend to put your linoleum needs to be smooth, clean, and dry without any bumps, dirt, oil, or paint that could prevent a tight fit.
Use a water-resistant Portland-cement filler to create a smooth surface. Mix to the consistency of peanut butter, then apply with a mud knife. Keep it smooth to avoid having to sand more than necessary.
Sand to a smooth, even surface.
While working on the floor preparation, put the linoleum tile in the room for a couple days to acclimatize to room temperature. (It tends to be brittle if it´s too cold.)
Use a chalk line to determine placement of tile. Use a carpenter´s square to make sure you have 90 degree angles.
If installing borders, precut edges with a utility or linoleum knife, then dry fit pieces. For a nice corner, cut 45 degree angles to miter joints
Apply adhesive according to manufacturer´s instructions, apply tile, then use a hand roller to ensure a good seal. A 100-pound rollers is recommended.
Once all the tile is laid, apply sealer according to manufacturer´s instructions.

Removing old linoleum
Removing old flooring is hard, dirty work no matter how you cut it. There are a few things to keep in mind before you start.
If the flooring is is firmly attached to the floor, your simplest course may be to put an underlayment down and not bother with stripping the old material up. Just screw down 1/4" masonite or cement board, mud the seams, and install your tile on top. This is especially effective if you are doing floors in different rooms and the difference in floor thickness isn´t apparent.
If you have to take up the old flooring, make sure that it does NOT contain asbestos. Old flooring was sometimes backed with asbestos and when it is disturbed it releases asbestos fibers into the air. It is a very BAD thing, so be careful. Take a small sample to your flooring company. They should be able to tell you if asbestos is present. If so, you´ll need to hire someone with experience doing asbestos abatement, or use an underlayment over the existing floor.
Methods of removal depend on how well attached the flooring is, the original adhesive, and the flooring itself. Often experimentation is needed to come up with the right approach. Using a pole, steel, or a razor scraper may work, various solvents including boiling water are common, or even renting a floor stripper might work. If you have a hardwood sub floor, try scoring the surface with a utility knife, then pull up as much of the flooring as possible. Take an old towel and fold it into quarters, then pour boiling water on the towel. Let it sit for a couple minutes. You should be able to scrape up the left over backing and adhesive.
Ultimately, removing old flooring is hard work and it may take a
few false starts to get the right combination of tools or solvents to
attack yours.

Maintaining linoleum
Once it is installed and sealed, you can keep it looking new for years by just sweeping, occasionally damp mopping, and applying a sealer periodically. The best way to make sure you care correctly for your linoleum floors is to read the manufacturer´s instructions for maintenance.
To mop, use just water or water and a little mild detergent. Don´t permit standing water because that may loosen the tiles around the edges. Some people add about a tablespoon of baby oil to the water occasionally to help restore natural oils lost over time.
To reseal the floors, use the manufacturer´s suggested sealant once a year or so. Or you may be able to use a water-based wax. To remove the wax, use isopropyl alcohol in water (1 part alcohol to 3 parts water) to remove the old wax. Scrub well and rinse thoroughly. Make sure the area is well ventilated, wear gloves, and something to protect your eyes.
Never use harsh solvents or cleaners though. Those with a high or low pH can discolor and pit the floor´s surface.
