Modular, Prefabricated Sandwich Panels supporting rapid, robust and safe constructions.

Overview

HPCC

As businesses adopt faster and innovative construction solutions, Rinac’s InstaBuild, prefabricated sandwich panel systems are the perfect choice for sturdy yet aesthetic modular constructions. This translates to reduced construction time at the site, cost-saving, flexibility, better quality control as well as sustainability. Moreover, you avoid dealing with local construction issues such as skilled labour availability or regulations!

These steel-faced, polyurethane-insulated composite panels help create clean, dust-proof, energy-efficient structures with excellent insulation properties. These panels can be free-standing or supported with steel structures. We also provide specially-engineered panels that work perfectly for walk-on ceilings, insulated roofs, as well as walls and floors.

Rinac has also developed InstaBuild, walkable, insulated ceiling panels to offer you a complete construction solution. A superior alternative for conventional and false ceilings, InstaCeil is a prefinished ceiling with exceptional fire-resistant and thermal properties, reducing radiant heat transfer and enhancing your comfort level.
