SGG CONTRAFLAM® N2

SGG CONTRAFLAM N2 is a multi-laminated and fully insulating fire-resisting glass produced from two or more panes of tempered safety glass, separated by clear, colorless advanced intumescent interlayers. In case of fire, the interlayers absorb the energy from the fire, limiting the temperature rise to the non-fire side, protecting people and property.

Installation
SGG CONTRAFLAM N2 should be installed only into listed fire-rated door and frame assemblies using suitable setting blocks and closed cell PVC tape, pure silicone, or ceramic glazing tape. Allow for minimum edge coverage of 3/8" and a minimum edge clearance of 1/4".

Check that opening is plumb and square. Inspect carefully before installation; do not install glass that has visible edge or surface damage. Place setting blocks (3" min) at sill, located at approximate quarter points. Check perimeter clearance and adjust setting blocks as needed. Do not block the lite so as to restrict movement due to thermal expansion; direct glass-to-perimeter frame contact should be strictly avoided.

SGG CONTRAFLAM N2 is an engineered specialty fire-resistant glazing material. Certain optical and visual imperfections are inherent in the production process. These characteristics may be evaluated according to the manufacturer’s quality standards but do not impair the transparency or affect the performance of the glass in case of fire, and shall not be considered cause for rejection.

Labeling
Each lite of SGG CONTRAFLAM N2 will be permanently labeled, in accordance with NFPA 80, with the product and manufacturer’s name, testing laboratory, fire rating and safety rating.
