Base insulation Eliminate energy-related weak spots

Much heat can be lost to the exterior through exterior wall components that are in contact with the ground in particular via thermal bridges. The consequences: The house cools down more rapidly. More heating is required, thus increasing the heating costs. Base insulation, also known as perimeter insulation, can eliminate this energy weak spot in homes over the long-term.

Base and perimeter insulation boards

Efficient from the ground up

Base insulation boards efficiently insulate the base or ground contact area down to about 30 cm below ground level. They correspond to material class "B1 – schwer entflammbar (flame-retardant)" in accordance with DIN 4102 and are applied using the adhesion method. The thermal insulating composite system (ETICS) has an insulation value to 0.032 W/(m*K) with insulation layer thicknesses up to 300 mm. For the top coat in the base area, Brillux also provides a wide selection of finishing renders, flat facing bricks and ceramic coverings.

Base joint profile

ETICS Base Joint Profile 3815

Aluminum base profiles are often used as the lower ending of a ETIC system. This should be regarded as critical, however. After all, such profiles made of metal act as a significant thermal bridge on a recessed base insulation. With the development of the ETICS Base Joint Profile 3815, a solution was created for thermal-bridge-free, fast and easy formation of recessed base surfaces.

Application: fast and simple

When using the ETICS Base Joint Profile 3815, the facade surface is usually insulated first, followed by the base surface. This creates an impact-protected, exact and smooth transition between facade and base insulation without thermal bridge influence. There are different options for mounting the first row of facade insulation boards including the implementation using the innovative Qju mounting method.

Step 1

Affix the Qju fixing brackets horizontally and separated by a distance of approx. 50 cm (two per insulation board) with adhesive.

Step 2

Apply the adhesive, place the Qju insulation boards, align them so that they are flush, and fix them in place on the underside with fixing nails.

Step 3

Position the Qju insulation boards such that they are perpendicular and fix them in place at the top with Qju fixing brackets incl. nails.

Step 4

Mount the ETICS Base Joint Profile 3815, incl. corner connectors and plug connectors.

Step 5

Embed the mesh strip first, then the surfaces.

Step 6

Bonding of the base insulation boards incl. ETICS sealing tape.

Step 7

Implement the base reinforcement and finishing render coating done!

Facade insulation systems

The insulated facade should alsobe beautiful. Individual and unique. Brillux provides six perfectly coordinated ETIC systems for this purpose.


Facade design

An ETICS system means thermal insulation and lasting protection. At Brillux, however, it goes hand in hand with attractive facade design.
