1. Wall Insulation

1.1.

Interior Insulation

Advantages:


Easy installation, no need for scaffolding


No problems of exterior emissions


Cost
-
effective method


Faster Heating (Wall has less thermal inertia)


Insulation with plasterboard mounted on studs

Inconveniences:


Having to clean the studs if the rails are installed first


Loss of space, if the studs are installed after


Low thermal inertia

Cost
-
effective method


Faster Heating (Wall has less thermal inertia)


Inconveniences:


Difficult treatment of thermal bridges, like wall
-
floor
intersection


Medium Thermal Inertia


Standard solution in Spain, with approximately 25 million square
meters every year.

ades


Multiple options for exterior finish


Low possibility of interstitial condensations

Inconveniences:


Difficult application, need for scaffolding or cranes


More product loss and emissions into the
environment


Parked cars may be stained my small dropplets


High dependence on weather conditions
