construction equipements

To be able to work in height we may have so many options like scaffolding, hanging on rope or elevator work platform. Each has its own advantages and disadvantages. Working by hanging on rope can be the cheapest but it would be useful for only small tasks and whenever team has to work together this seems to be risky and annoying.
Scaffolding can be the good option as it holds working place and security regions. But in this project I am going to talk about, it has a prefabricated aluminium blocs to put on for the facades and scaffolding will not allow easily to put on the blocks. The third and the best option is elevator work platform. However it is a bit expensive but from the point of view of security it is the best option. Security is the big question in the construction industry today so in this project elevator work platform is used to pile the prefabricated blocs. Below are some photos of elevator work platform, facades and the team member including me who is in charge of this task.



Why to insulate building?

In this 21st century the comfort has been essence in the modern life. To live in comfort we need  favorable conditions like fresh air circulating inside the building, good average temperature irrespective of the weather etc. New laws on consummation of energy oblige us to make maximum utilization of energy provided  i.e. we may not be able to buy as much energy as we wan, it is costly on the other hand.

Now we started building low energy consuming housing which is only possible by proper insulation of building and using solar panels.  Insulating in general sense means to make a structure water-proof. We must know solar energy released by sun in a day is quite enough for the world for entire year.To gain a title like of high environmental quality structure we should pay very a careful attention to such subjects which demands a careful study on related topics.

In addition to insulate a structure  we need to cover a structure by a materials which has a good thermal resistance. In market we can have so many materials. However in limited budget we can’t do whatever we like because it demands a good calculation behind. If we use less insulation, condensation can take place inside the structure (which means there is big difference of temperature between two surfaces) as we can see in the classical buildings. A proper choice demands a calculation. However the commonly used insulation materials are rock wool( laine de roche in french), glass wool (laine de verre in french) ,extruded polystyrene (fr: polystyrène extrudé) etc.  Below is one example of rock wool used in building insulation.
