3.5.3.1 Plasterdboard laminates
Plasterboard laminates are widely used and easy to install. The available products’ insulation
thicknesses might cause a problem, if very high improvements in thermal insulation are
targeted. (EST 2005)
As an example, one manufacturers’ plasterboard laminate product range includes thicknesses
from 30 to 90 mm. With a plasterboard thickness of 10mm, this gives insulation thicknesses
from 20 to 80mm.

3.5.3.2 Insulation boards covered with plasterboard
The difference between this system and the plasterboard laminates is that the system
components are installed separately. The installation is not as fast, but the benefits are lower
cost and that the insulation thickness can be chosen freely.
