  • H.D.G.I wire method.
  • Mesh with subsidiary column method.
  • Angle iron method.

Insulation of  buildings

insulation of walls
Insulated Walls
Insulation Of Building Walls:-  This is the best and modern Technique of civil engineering where we insulate the walls internal sites of the building to maintain the temperature of house. This method is applying mostly in cold areas. Some of materials used for insulation are mention under here.
1. P.E. Foam
2. Wooden Strips
3. Reflective Foil
4. Polythene Sheet
5. Expended Metal Mesh
6. Plaster or ply wood
Q. Why insulation is important?

Ans:- Particularly in cold areas, we can't bear the cold temperature. Therefore, we insulate  internal sites of the building against by the cold temperature.
