INTRODUCTION TOVENEERS Veneer refers to thin slices of wood,

usually thinner than 3 mm (1/8 inch),that typically are glued onto core panels(typically, wood, particleboard or medium-density fibreboard) to

produce flat panels such as doors, topsand panels for cabinets, parquet floorsand parts of furniture.

Plywood consists of three or more layersof veneer, each glued with its grain at

right angles to adjacent layers forstrength. Veneer is obtained either by "peeling"

the trunk of a tree or by slicing largerectangular blocks of wood known asflitches.

TYPES OFVENEERS Raw veneer : has no backing on itand can be used with either sidefacing up.

Paper backed veneer : veneersthat are backed with paper

Phenolic backed veneer :lesscommon. Mainly used for composite

or manmade wood veneers. Laid up veneer : raw veneer joinedtogether to make larger pieces.

Reconstituted veneer : raw veneer cut and attimes dyed. Usually made from fast-growingtropical species.

Wood on Wood : decorative wood veneer facewith a utility grade wood backer that is applied tothe opposing direction to the face veneer. Alsocalled 2-ply.Multilaminar wood veneer : uses plantationwood to reproduce decorative effects which are

typical of quality wood species (often protectedand rare).

Edge lifting from substrate

- Insufficient adhesive coverage- insufficient dry time- not enough pressure when applying

Possible Solutions:- apply more adhesive to veneer and- substrate

- Increase drying time for adhesion- apply more pressure

Bubbles in the Veneer- trapped solvent- edges bonded first- uneven adhesive coverage- uneven pressure- ineffective glue

Possible Solutions:- increase dry time- apply pressure from center outwards- review application procedure

- review pressure procedure- use glue with more solids

PROBLEMS TH N C

DV NT GES Furniture made with wood veneer uses less wood than

the same piece of furniture made with solid wood.

Toxicity : Nontoxic; veneer stores carbon and also

maximises the use of harvested wood. It is cost efficient.

Creates new design philosophies.

DIS DV NT GES The qualityof wood veneers is absolutely lower

compared to its hard wood counterpart. Veneer products are extremely thin and more

susceptible to water damagea problem that will causethe material to peel and reveal the particle boardbeneath it.

Maintenance is expensive. Veneers expands or contracts according to the climate

whereas, the material below it does not expand orcontract at the same rate causing the veneer to crackovertime.

INTRODUCTION TOL MIN TES Laminates are a multi-layersynthetic flooring product. It iscreated high-density fibre,melamine resin or wood particles.On top, the laminate has a

photographic appliqu layer, whichis in turn covered with a clearprotective layer.

Laminates are laminated productsprimarily used as furniture surface

materials or wall panelling. Laminate is a manufactured

product that simulates the look ofhardwood, ceramic tile, natural

stone and many other types offlooring.

L MIN TE ST ND RDS They are specifically applied for high-pressure decorative

laminates. European Standard EN438 : The European Standard EN438 is

one of the standards that most decorative laminates manufacturersselling to worldwide market adhere to. The specific code is EN438,

entitled: Decorative high-pressure laminates (HPL) sheets based onthermosetting resins, specifications.

Anti Bacterial: Antibacterial properties are important fordecorative laminates because these laminates are used as kitchentops and counter tops, cabinets and table tops that may be inconstant contact with food materials and younger children.Antibacterial properties are there to ensure that bacterial growth isminimal.

Fire Resistant and Flame Retardant : There are many differentstandards with regards to fire resistant and flame retardantproperties of High Pressure Decorative Laminates.

TYPES OFL MIN TES Glue less laminate flooring : glue less installation makes these floors quick and easy-to-install.Most laminate floors require a plastic underlay sheet (4 mil poly) be installed directlyunderneath the laminate planks or tiles. This helps the floor float freely over the subfloor.Another option is to add a vapour barrier or noise reduction underlay before installing thelaminate flooring.

Laminate flooring with attached underlay : These floors come with several different types oftongue and grooved locking systems and an attached underlayment to reduce noise levels.

Glued laminate flooring : These are the original laminate floors that do require a specialformulated glue to be applied to the tongue and grooved areas for each plank. Once the glue isdried the planks are almost impossible to pull apart. These floors are offered in both planks andsquares.

Pre glued laminate flooring : No mess, because the glue is already applied to the tongue andgrooves which makes these floors quick and easy-to-install. A thin, plastic underlayment isneeded to seal out moisture and prevent the glue from sticking to the substrate.

INST LL TION METHODFOR L MIN TES Flooring should sit in the room for at least 48 hours

prior to installation, giving it time to expand orcontract in relation to the room's temperature andhumidity. This prevents buckling and otherproblems after installation.

Use the pry bar to remove baseboard from the walland set the pieces aside for reinstallation. Floatinglaminate planks (the kind used in this project)should be installed over a hard, smooth surface,such as vinyl. Remove damaged flooring to revealthe subfloor.

Clear the floor of staples, nails, and other debris.

Roll out the underlayment. Do not overlapadjoining strips. Use the utility knife to cut pieces asneeded. The foam underlayment deadens sound andhelps the floor feel more resilient.

This underlayment allows the floor to expand andcontract with changes in temperature and also acts

as a sound and moisture barrier.


13/17

In some installations, there are two underlayment layers. The first

layer is installed to specifically act as a moisture barrier while the

second layer provides a sound barrier and enhances yourfloorings performance. The underlayment is typically rolled out and taped together at the

seams. Installers will cut the pieces of underlayment where needed with a

precision utility knife to make a perfect fit. Installers will typically begin in the left corner of the area and

leave a minimum 1/4" space between the flooring and theperimeter walls. This is done because the laminate requires space around the edges

of the room to expand or contract. Without that breathing room your floor will express its

discontent. If the floor is touching or too close to a wall, it canbuckle in the middle.

Along the wall, the installers use spacers as they work, to ensurethe accuracy of this perimeter space.

They use one spacer for each square foot. Once your floor is fullyinstalled they remove the spacers and cover the perimeter gapwith quarter round trim or a wall base.

As the installers lay the planks or tiles in the desired pattern, theywill carefully measure and precisely cut them to fit.

PPLIC TIONS

high-pressure laminates are usuallyused for furniture tops especially onflat surfaces, including cabinets andtables.

They are also used in models thatinclude wall panels with conceptual

designs and custom prints.

DV NT GES Exceptional durability

Easy to clean surface

Superior stain resistance

Superior fade resistance

Install in/on all grade levels, even below grade

Install over many different types of subfloors

Great impact and indentation resistance Exceptional realism at affordable costs

Easy to replace later on, if desired

DIS DV NT GES While laminate can simulate the look of hardwood, stone, or

brick perfectly, the illusion fades as soon as you feel thematerial with your bare hands.

When you walk on a laminate floor it produces a hollow

sound, that makes the material feel fake and manufactured. Laminate flooring is quite hard and unyielding under foot. Some environmental experts have expressed concerns over

laminate materials that are made with compounds derivedfrom formaldehyde. They claim that floors made with thesematerials can release volatile organic chemicals over time,which can have harmful effects on the air quality of thesurrounding room.

The life span of a laminate floor is going to be based on the

quality of the material and the thickness of the wear layer.
