Quick-Fix System® — IHT Fixing and Installation System
The Quick-Fix® System is IHT’s unique and patented installation system, developed to assemble composite decking, façade cladding, and composite fencing quickly, simply and with high efficiency.
It enables installation up to 3 times faster, using only 1 screw per board, and allows individual boards to be lifted for easy access to the substructure for cleaning and maintenance.
How does the Quick-Fix® System work?
Quick-Fix® is a click-in system that is extremely easy to install and uninstall.
It is composed of:
- Structural joists in PVC and aluminium, creating stable substructures for floors, façades and fencing.
- Specific fixing clips for different installation scenarios.
- Complementary accessories that guarantee levelling, stability and perfect finishing, regardless of the application.
Its ease of use makes it ideal for professionals and DIY projects alike.
Main advantages of the Quick-Fix System®
Thanks to the locking system with only one screw per board.
No visible screws, ensuring a cleaner, more modern finish.
Boards can be lifted individually for deep cleaning or maintenance.
The system allows the materials to expand and contract, adapting to temperature and humidity variations.
All components are designed to withstand demanding weather conditions and ensure system longevity.
