As the demand for contemporary window design with sleek frames and window sills is constantly growing, a new window support strategy for conventional cavity wall
structures is required, because the conventional concrete window sill has no use anymore.
Triotherm thermal brackets do create the required structural support for windows in the cavity in a simple way, as the installation principle is just reversed in
comparison to EWI.
Instead of installing the Triotherm on the outside, it is located in the cavity and bonded either against the outer leaf or the inner leaf. The mechanical fixing is
carried out through the masonry into the triotherm. Please ensure a slightly bigger borehole through the block (e.g. 8mm for 7.5mm concrete screws) to allow a firm press of Triotherm towards the
block or brick.
To compensate the slope of the aluminium window sill, it is required to raise the window frame above the wall level. We´d recommend to consider the Triotherm Base
profile as connection profile (packer) in between Triotherm+ and the window frame.
