Subsequent roof insulation and roof insulation

Roof insulation and roof insulation are among the most important measures for saving energy. Old buildings in particular lose a large amount of heat through the roof.
Among other things, a good roof insulation ensures that it is neither too hot nor too cold under the roof.
Also, the roof insulation can ward off moisture, which in turn contributes to the formation of mold, which represents a not insignificant health hazard. In addition, the roof insulation allows no heat escape from the house and no cold penetrate, so that significant savings in heating can be achieved.
Now, in many cases, all work has already been done without thinking of the roof insulation. In this case, a subsequent roof insulation must be done, for which basically three variants are available: The
Rafter insulation, the rafter insulation and the under rafter insulation. All three variants can be easily combined with each other, but also offer advantages and disadvantages.
The
Rafter insulation

As a subsequent roof insulation is the
Savings insulation usually not suitable. It can only be applied if the roof is completely covered. If the roof of the house but anyway to be re-covered, is the
Savings insulation is the best solution, since no thermal bridges can arise here.
In this form of roof insulation, an insulating layer is applied directly to the rafters. It sits between rafters and roof cover so that no thermal bridge is present.
The intermediate rafter insulation
The second
Variant is the rafter insulation. It can be used both as a roof insulation from inside and outside. The insulating layer is inserted between the rafters during the intermediate rafter insulation. If the roof is newly covered, the rafter insulation can be done easily from the outside and is suitable as a supplement to
Rafter insulation.
Then the rooms underneath do not have to be renovated again. It looks different if the rafter insulation is to be done from the inside. In this case, supplementing with the under rafter insulation is absolutely recommended in order to achieve better insulation.
The lower rafters insulation
The third variant for the subsequent roof insulation is the Untersparren insulation. Here, the insulating layer is mounted below the rafters. Since the intermediate rafter insulation sometimes causes thermal bridges, these can be compensated by the lower rafter insulation. It should be noted, however, that the space located directly under the roof is somewhat reduced by the lower rafter insulation.

FAQ - 💬

❓ What is the difference between ceiling insulation and roof insulation?

❓ What is the gap between roofing membrane and insulation?
