Easy installation, safe transport
RotaFix has been developed with on-site efficiency in mind. Because the window sill is installed at a later stage than the mounting profile, the risk of damage during transport, storage and structural works is significantly reduced.
Prefab walls can be transported tightly together without protruding elements. At the construction site, the window sill profiles are installed quickly and easily. This speeds up the construction process and helps reduce failure costs.
Clean finish with concealed fixings
Installation of the RotaFix Window sill 35 RF is carried out using plastic anchors, keeping all fixings completely out of sight. Where additional securing is required, a custom-made aluminium screw anchor can be applied.
The result:
- No visible screws
- A clean, modern façade design
- Consistent, high-quality finish
Sustainable aluminium
Like many of Comhan’s façade components, the RotaFix® 35 RF is made from aluminium. This material is lightweight, strong, and fully recyclable. In addition, the RotaFix base profiles and window sills are manufactured from aluminium with a high percentage of post-consumer recycled material, resulting in a low CO₂ footprint. These profiles are therefore perfectly aligned with the growing demand for sustainable, circular, and future-proof construction.
