RAL installation is a professional method of fitting windows and doors that ensures long-lasting thermal and sound insulation as well as protection against moisture. This installation is carried out in accordance with German RAL guidelines and standards.
The main difference between RAL installation and conventional installation lies in controlling vapour diffusion and preventing moisture from penetrating the wall, which prevents condensation, mould and damage to the joinery.

Layers of RAL installation
Inner layer – vapour barrier
Prevents internal vapour from penetrating the joint between the wall and the window.

Middle layer – thermal and sound insulation
PU foam or a special tape is most commonly used. It provides strength and insulation.

Outer layer – vapour-permeable tape
Allows moisture to escape outwards, but does not permit water and wind to penetrate.

Advantages of RAL installation
- Elimination of mould formation and condensation
- Better thermal and sound insulation
- Extends the service life of the joinery
- Energy efficiency and savings
- A professional and aesthetically perfect finish

When is RAL installation recommended?
- In new construction and low-energy houses
- When replacing joinery where superior insulation is desired
- In buildings with increased humidity (bathrooms, kitchens…)
