Some of the most important building materials are:

However, timber is still employed as a building material in the form of boards. For the interior of buildings plywood and veneer serve a number of purposes.

There exists variety of bricks for different purposes: ordinary, hollow or porous, lightweight, multicolour bricks for decorative pur¬poses, etc. Bricks are usually laid in place with the help of mortar.

Metals:

A lot of decorative plastics, now available, have brought about a revolution in interior and exterior design. But plastics are used now not only for decoration. These materials are sufficiently rigid to stand on their own without any support. They can be worked with ordinary builders' tools.

Structural foamed glass blocks designed to fill ceilings, and for making interior partitions in buildings and rooms, to ensure heat and sound insulation.

Material: timber, brick, stone, concrete, metal, plastics and glass.

Type:   Timber is provided by different kinds of trees. Timbers used for building purposes are divided into two groups called softwoods and hardwoods.

There exists variety of bricks for different purposes: ordinary, hollow or porous, lightweight, multicolour bricks for decorative pur¬poses, etc

Metals: aluminium (in the form of various alloys), brass, steel

Plastics are artificial materials used in construction work for a vast number of purposes.

Foamed glass is a high–porosity heat insulating material, avail¬able in block made of fine–ground glass and a frothing agent.

Properties:​ Timber is still employed as a building material in the form of boards. For the interior of buildings plywood and veneer serve a number of purposes.

A brick is best described as a "building unit". It may be made of clay by moulding and baking in kilns, of concrete, of mortar or of a composition of sawdust and other materials.

Aluminium, principally in the form of various alloys, is highly valued for its durability and especially for its light weight, while brass is frequently used for decorative purposes in facing.

Steel finds its use in corrugated sheets for roofing, for girders, frames, etc. Various shapes are employed in construction.

Plastics have some good ad¬vantages as they are lighter than metals, not subject to corrosion, and they can be easier machined. Besides, they are inflammable, they can take any colour and pattern, and they are good electrical insulators. More over, they possess a high resistance to chemical action.

Laminate is a strong material manufactured from many layers of paper or textile impregnated with thermosetting resins. This sandwich is then pressed and subjected to heat. Laminate has been developed for both inside and outside use. It resists severe weather condi¬tions for more than ten years without serious deformation. As a struc¬tural material it is recommended for exterior work. Being used for surfacing, laminate gives the tough surface.

Foamed glass has a high mechanical strength, is distinguished by moisture, vapour and gas. It is non-inflammable, offers resistance to frost, possesses a high sound adsorption, and it is easily sewn and nailed.
