Keralite products should be installed only into listed fire rated frame assemblies with suitable setting blocks and glazing tape. Check that the opening is plumb and square. Carefully inspect glass edges before installation. Superficial chips smaller than 5/32" (4mm) are acceptable, wider chips or deep chips (with V profile) are not acceptable and should not be installed. Place setting blocks (3" min) at sill, located at quarter points. Do not block the glass and avoid restricted movement due to thermal expansion, direct glass to perimeter frame contact should be strictly avoided. Check perimeter clearance and adjust setting blocks as needed.
Keralite is a specially engineered fire protective glass-ceramic material. Its primary function is fire resistance integrity. Certain optical and visual faults are inherent to the manufacturing. process, according to our quality standards. These characteristics do not generally impair the transparency or affect the performance of the glass in case of fire; and therefore, should not be considered cause for rejection or replacement.
STORAGE AND HANDLING
Keralite should be handled with care during transportation, storage, inspection, and installation. Store in a dry place. Do not pile Keralite in a horizontal position.
Care must be taken not to scratch the film applied to one of the glass surfaces. The film is applied on the opposite side of the UL stamp / logo.
Do not use bristle brushes or abrasive cleaning materials. Cleaning methods used should be similar to those used on Plexiglas.
A soft cloth or clean synthetic sponge is recommended for washing and do not use the same cloth or sponge for wiping sills or frames.
A squeegee of 70 - 85 durometer hardness is recommended for removal of wash water and dirt from the film. Do not apply heavy pressure in any cleaning operation.
Do not leave the film wet.
Make sure to use a different sponge, cleaning cloth and water for cleaning the outside and the inside of the windows.
