4. 1. Wall Insulation 1.1. Interior Insulation
Insulation with plasterboard mounted on studs
Advantages:
Easy installation, no need for scaffolding
No problems of exterior emissions
Cost-effective method
Faster Heating (Wall has less thermal inertia)
Inconveniences:
Having to clean the studs if the rails are installed first
Loss of space, if the studs are installed after
Low thermal inertia
