2.1.2 Adding or increasing internal insulation in walls

2.1.2 Adding or increasing internal insulation in walls

Description

The internal insulation system is based on the placement of thermal insulation in the internal layers of facades and party walls to coat after with a new internal finish, usually of plasterboard panel, or cladding finish of hollow brick. This system leaves out of the envelope the thermal mass of the wall, and therefore it allows a rapid warming of the habitable areas. In return the closures will not radiate the stored heat during the day to the inside.

Benefits

  • Ease and speed of execution without the need of install auxiliary means

  • Suitable for buildings that need heating with an intermittent use

  • The outside finish is not conditioned

  • This system is a good choice where there is impossibility of acting from outside or where the building façades are classified or protected

Limitations

  • Risk of condensation. It can be necessary a vapour barrier, especially in humid areas

  • Lost useful surface

  • Costly treatment of thermal bridges

  • Do not use in areas of the building with humidity pathologies

Economic assessment

Between 17 and 39 €/m2 depending of the installation method (plasterboard panel or hollow brick internal finish)
