The Thermal Packer has been developed for creating a base underneath the window and door frames. Due to its depth of 64mm, it will fit perfectly for the most available windows and door systems.
To joint the bracket with the window frame, a mechanical fixing is required.
The Thermal Packer can be linked with the standard Triotherm thermal supports, e.g. when installing windows in the cavity without conventional concrete sills. It creates a secure and approved installation strategy for aluminium window sills without thermal bridging.
