Exterior Sheathing

Three different methods are applied for heat insulation in buildings which are interior, exterior and cavity walls. The best application to prevent the formation of heat bridges and to ensure the continuity of the insulation is the sheathing application. Exterior sheathing application is the most suitable heat insulation system in terms of building physics.

Exterior sheathing is the coating of the building's exterior envelope with heat insulation materials in order to prevent heat losses and gains depending on seasonal conditions. Technically, it is the heat insulation made on the exterior surface of the building to reach the required heat transmission coefficient without creating a heat bridge.

When it comes to exterior sheathing types, the first method that comes to mind is the sheathing method. The reason for this is that it is the most well-known method, since its application is low-cost and used almost everywhere. It can be done in three different ways, which can be applied to interior, exterior and both parts of the building.

According to the Energy Efficiency Law No. 5627 and the Energy Performance Regulation in Buildings issued according to this law, it is required to comply with the insulation standards as of 1 January 2011. In addition, in the old buildings built before this date, it is obligatory to obtain Energy Identity Certificate until May 2, 2017.
