Insu® Jac Pedestal System

Adjustable Pedestal Leveling System
Insu® Jac Pedestal System is a high-performance adjustable support system engineered for raised flooring, timber decking, stone pavers and rooftop applications. Designed for flexibility and durability, the system allows precise height adjustment while creating a level finished surface over uneven substrates and sloped waterproofed areas.
 
The modular pedestal system improves drainage performance beneath raised floors by creating a continuous void space that allows water flow, ventilation and easy access to waterproofing systems and concealed services.
 
Suitable for roof decks, podiums, balconies, terraces and landscaped areas, the Insu® Jac Series supports various architectural finishes including timber decking, porcelain tiles, concrete pavers and stone slabs.
 
The system includes a complete range of pedestal bodies, shims, slope correctors and accessories to accommodate different project conditions and installation requirements.
 
Manufactured with high compressive strength materials, the Insu® Jac System provides long-term structural stability, installation flexibility and efficient maintenance access for modern architectural and landscape projects.

Fire-resistant versions are available for selected project requirements.
