BP 20
Under-sill profile with mesh
Contact us
APPLICATION
For creating the junction between the window sill (PVC, steel, stone, galvanized) and the thermal insulation system.
CHARACTERISTICS
PROPERTIES
- proper connection between the sill and the thermal insulation
- elimination of thermal bridges under the sill
- reduction of wind-induced acoustic effects
INSTALLATION
The BP20 under-sill profile is equipped with a special expansion adhesive foam and fiberglass mesh.
- Remove the protective film from the foam.
- Glue the profile under the window sill after carefully cleaning the inner surface of the sill (dust, dirt, grease).
-
Embed the integrated mesh of the BP20 profile into the adhesive, then immediately cover it with the façade reinforcement mesh, ensuring an overlap.
The bonding of the BP20 profile and the installation of the mesh should be carried out in a single operation.
SPECIFIC FUNCTION
The BP20 profile eliminates the “under-ventilation” effect beneath the sill, caused by a gap between the sill and the insulation.
Wind entering this space creates an unpleasant whistling noise and cools the window area.
