Ballistic & Forced Entry Grade Sub-framing
Riot Glass® J Series sub-framing is available in ballistic and forced entry grades and designed to provide a smooth, even surface for mounting our secondary glazing systems.
The J Series is custom-made to the dimensions of each individual window opening. Acting as an exoskeleton, the J Series provides a suitable structure to which we can attach our AP and RG Series retrofitted systems.
The J Series is only required when existing framing conditions are not conducive to retrofit. Examples may include damaged or uneven existing framing or other limiting factors.
The J Series is not a standalone product, but a foundation for our primary framing when required to provide a smooth, stable mounting surface.
