Insulate the roof from above using Bituminous

Bituminous sheets with silver coating on one side are available for top insulation of the roof. They not only reflect heat and insulate but also protect the roof from water leakage. They are about 8 mm thick and have a silver coating on the exposed side. They are glued to the roof with bitumen liquid.
Insulate the roof from below

Another option is to blow cellulose insulation into the free space between the floor and the ceiling below. To do so, one makes little holes in the ceiling or concrete floor. Cellulose insulation primarily insulates air noises. In order to mute impact sounds as well, you should choose a thick insulation layer.

Avoid the heat transfer from the roof to the room

• Simple ways to reduce heat loss include fitting carpets, curtains and draught excluders. It is even possible to fit reflective foil in the walls or on them.
• Heat loss through windows can be reduced by using double glazing. These special windows have air or a vacuum between two panes of glass. If the double glazing has a vacuum there will be no conduction or convection. If the double glazing is made with air between the glass then convection is minimised because there is little room for the air to move. Air is a poor conductor so there will be very little heat loss by conduction.
• Heat loss through walls can be reduced using cavity wall insulation. This involves blowing insulating material into the gap between the brick and the inside wall. Insulating materials are bad conductors and so this reduces the heat loss by conduction. The material also prevents air circulating inside the cavity, therefore reducing heat loss by convection.
• Heat loss through the roof can be reduced by laying loft insulation. This works in a similar way to cavity wall insulation.

Extract the hot air collected below the roof

Warm air rises because it is lighter than cool air. In commercial buildings such as factories and workshops, the warm air generated by machinery and workers rises into the roof space where it is trapped. The sun heats the air in the roof space to over 60C (140F); in turn this superheated air heats both the structure of the building and the cooler air below.
