Hardwood & Softwood

•Softwoods are found in building components e.g., windows, doors, furniture, medium-density fibreboard (MDF), paper, Christmas trees, use to make balustrade or composite block boards for bookshelves or panelling. Pines are one of the most commonly used softwoods.

•Poor in fire resistance

•Low in cost

•hardwoods are more likely to be found in high-quality furniture, decks, flooring, and construction that needs to last. Used in fixtures such as stair tread, doors. Available in laminated veneers and sheets

•Lumber is stronger, denser and homogeneous.

•Good in fire resistance

•Cost is high

Comparison Between Wooden and Metal Furniture:• Design :

▫ Wood : limited shapes▫ Metal : flexibility in forming and shape

• Weight▫ Wood : heavy▫ Metal : could be light ( aluminum )

• Firefighting▫ Wood: easy to burn▫ Metal : does not burn easily

• Cleanness : ▫ Wood : could be cleaned but it is difficult to use water / A material

liked by insects that hide in .▫ Metal : easy to clean by water and it is not a field for insects

• Shape and looking :▫ Wood : fixed shape▫ Metal : could have different shapes using colors and paints

• Construction :▫ Wood : complicated using glue and nails▫ Metal : could be fixed and unfixed easily

• Safety :▫ Wood : needs efforts to be smooth and easy to scratch.▫ Metal : smooth surfaces and bears scratch / could be used for multi-

loch doors .

Glass is a chemically inert, brittle, hard but transparent construction material.

Glass is an element that helps us to achieve this goal of creating an empty space. It’s the optimal solution for room that receive too little light. making your home look spacious

.Laminated glass is a type of safety glass that holds together when shattered.

.In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyric (PVB), between its two or more layers of glass.

.The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces.

. Windshields --- when cracked produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. Used where security is concern like for high grade construction , curtain wall , architectural ceiling , elevator parapet , skylights.

Specification : standard glass comes in 4-25mm thickness

Laminated glass

•Huge range of colours available•Coloured laminated glass•Transparent and translucent

•Glass wall curtain – weather proof•UV protection•Acoustic insulation

•Balustrade

Toughened or tempered glass is glass that has been processed by controlled thermal or chemical treatments.

It has increased strength compared with normal glass and will usually shatter into small fragments, rather than sharp shards, when broken.

Toughened glass (tempered glass)

The ellipse table has a walnut wood base and a barrel-shaped tempered glass top.

•The use for laminated glass ranges from entrance doors and glass floors to aquariums and display cases

•Tempered glass is almost 5 to 10 times stronger when compared to its untempered counterpart. One very noticeable quality of this type is that it breaks down into small granular pieces rather than sharp shards.

•tempered glass can take a higher load and deflects further before breaking. However once the glass is toughened it cannot be reworked.•Polishing and drilling holes into the glass needs to be done pre-toughening.

•Ground level doors and windows made from laminated glass are a safe bet. This is also the most susceptible area when it comes to breaking and entering.

Laminated / toughened glass :

Fusion GlassFused glass is a term used to describe glass that has been fired (heat-processed) in a kiln at a range of high temperatures from 593º C (1100ºF) to 816º C (1500ºF).

There are 3 main distinctions for temperature application and the resulting effect on the glass.

Fused glass consists mainly of silica.

While the precise origins of glass fusing techniques are not known with certainty

Float GlassFloat glass is a sheet of glass made by floating molten glass on a bed of molten tin.

This method gives the sheet uniform thickness and very flat surfaces. Modern windows are made from float glass.

Most float glass is soda-lime glass, but relatively minor quantities of specialty borosilicate and flat panel display glass are also produced using the float glass process.

•Most widely used type of glass• Monolithic and highly transparent•Manufactured in two main varieties, i.e.; clear and tinted.•Used in mirrors , windows,curtain walls and doors.•float glass can be toughened, a process that creates safety glass out of annealed glass. •Available in thicknesses 2-19 mm•Can be coloured during manufacturing

Stained GlassAs a material the term stained glass generally refers to glass that has been coloured by adding metallic salts during its manufacture.

The coloured glass is crafted into stained glass windows in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead and supported by a rigid frame.

Painted details and yellow stain are often used to enhance the design.

The term stained glass is also applied to windows in which all the colours have been painted onto the glass and then annealed in a furnace.

Etched glass

•Etching refers to the technique of creating art on the surface of glass by applying acidic, caustic, or abrasive substances.

•Glass with excellent finish to match your interiors.
