Tougher building codes are addressing three major areas in construction: fire, energy and water/mold.   Common wood sheathing burns or rots.  Gypsum products can meet fire codes, but are not structural, damaged by water and susceptible to mold.  Continuous insulation is typically on the outside of the sheathing; requiring layers of materials to protect the assembly from fire, water penetration and impact. It is a complex and costly approach.

Through proprietary formulations and manufacturing, ROK-ON™ was developed to eliminate many layers of protection traditional systems require to achieve code compliant walls.  ROK-ON™ SIS is fire, water, mold, termite and impact resistant.  It has a non-combustible, impact and water- resistant structural board on the exterior of a thermal barrier.  This allows for simple, direct application of finishes or cladding without expensive attachment systems to increase construction velocity and lower installed cost. It is the ideal configuration for a continuous insulation substrate.
